Enterprise Distribution of Blackberry application - deployment

Is there any enterprise distribution program for blackberry applications?
Is there any method similar to Apple's enterprise distribution of iphone applications?
While going through their documentation, they are talking about using a deployment server and distributing apps with it.
Note: for early OS versions of blackberry - OS 7 or previous versions are my target

As Peter said in his answer, you can use BES to distribute applications in an Enterprise environment.
In iOS, the Enterprise program is basically the only Apple-approved way to deploy software, other than via the iTunes App Store (ignoring how you deploy to your test team).
BlackBerry Java (e.g. OS 5,6,7) devices don't have the same restriction on apps that Apple has implemented. Normal jailed iPhones cannot install software from any arbitrary web server, but BlackBerry devices can.
So, another option is just to post your app (.jad and .cod files) to a (corporate) webserver, and let users download the apps themselves. This is called Over-The-Air (OTA) deployment.
I'm not endorsing this over BES deployment, just adding to your options.

Sorry, don't know anything about iPhone Enterprise distribution.
For BlackBerry, there are two 'variations' depending on whether you are talking BB10+ or BB7- phones. However in principle they are the similar, the BlackBerry Administrator makes an application available to the corporate BlackBerry devices associated with the corporate BES, and these can be pushed to the phone, or can be made available to the phone (for BB10).
A possible restriction here is that the application will only made available to BlackBerry devices associated with that specific BES.
There is more available from the link you have already found.
I think to give a more specific answer we need to understand what you are trying to achieve, and if this is targeted to BB10+ or BB7- devices.
Edit:
Since you have indicated that you are targeting BB7 and earlier, then I would recommend one of these approaches:
a) If you wish to force users to have your software, then the best approach is create a software profile on the BES
b) If the software is optional, then place it on a corporately accessible web server and OTA download as described by Nate. This is significantly easier to maintain than the BES distribution.

iPhone development on Windows
I want to build apps for the iPhone but i can't find a right program.
I don't have a mac, so xcode isn't possible. I used MobiOne, but i had to pay, and i prefer a program that's completely free.
I want to ask if some of you know a program to build native iPhone apps thats compatible with windows and is completely free.
Yours,
Gromdroid
You need a Mac computer with an Intel CPU and MacOS X 10.6+, and a copy of the Xcode software (it's free) to build apps for iPhone. That's the Apple policy. They just don't license the build toolchain to anyone. Even with third party iOS-compatible SDKs like Mono or PhoneGap you have to produce the final build on Xcode.
A Hackintosh or MacOS X under VMWare is probably your best bet, short of buying the cheapest Mac Mini you can find.
To upload your apps to the App Store or to live devices (as opposed to the emulator) you'll have to pay, too. $100/year for a basic account.
EDIT: IIRC, in the latest policy, you can run and debug on devices without a paid developer account. To upload to the App Store, an account is still required.
I don't know much about this, from my limited knowledge,you can Use phone gap for application development. It's free and you can develop applications for I-phone,android,windows mobile,black berry etc using this sdk.
Titanium sdk is another one.
But you need to create IPA on XCode for installing it on Apple devices (Iphone,Ipad etc).
It's better if you install Mac OS on your windows machine using Virtual box (Virtual box).
Please check the sdk links.
Phone gap
Titanium
if you're good in java/lwuit programming you can also check Codename One http://codenameone.com
you use their designer and framework, and you publish to iphone, android, j2me etc..
you'll still need development certificates.

iOS development on Windows [duplicate]

How can I develop for iPhone using a Windows development machine?
I've read a lot of questions and answers about developing iOS apps on Windows:
iPhone development on Windows
How can I develop for iPhone using a Windows development machine?
But most of the ways to accomplish this is because the people with this problem (make ios apps on windows) want to make apps for themselves. Also, some of them suggest web apps.
I'm working for a company who needs to make a little App (later other companies will need more) and the person who is in charge of all about IT told us that we need some facts so we can demonstrate that we really need a Mac for developing apps for iOS legally.
First, I don't know if all that says on this page would be enough https://developer.apple.com/support/ios/ios-dev-center.html
To develop with the iOS SDK and Xcode, you must have an Intel-based Mac
running Mac OS X Snow Leopard or later and you must be registered as
an Apple Developer.
Now I have some questions:
Is there a legal way for a company to make iOS apps on Windows?
If one of those ways is running OS X under a Virtual Machine... Is it possible to do it with OS X Lion USB Thumb Drive?
I know there are some SDK such as Marmalade, Corona, DragonFire... and they give us licenses but are they 100% reliable? Would apple give us support if we use one of these SDK?
Does Apple check if the app was created over a legal OS X copy? I mean, when the code is compiled, is there a sign so Apple can check that the app was made without cheating?
Creating games on OS X (VM) would be hard?
In the case we get the Mac (mini)... Would we need the Magic Touch or Magic Trackpad to test multi-touch? Or is only possible doing it by pressing one of the keys plus the left click?
Creating Web Apps would be a solution? I know that we can't use the Camera of the device using Javascript but is the rest ok?.
Testing
Some of our co-workers have iTouchs but we don't know if the company should buy a new one. Also, Would you suggest to get the oldest generation of iPod Touch for testing purposes or only the 3rd and 4th generation?
I hope you could understand me. Thanks in advance!
Update:
I got this answers:
You will work over Windows with the respectively SDK
Me: I know there isn't an official SDK for developing iOS apps on Windows from Apple.
The programming language that we will use is the same it would be install on a PC or MAC.
Me: Impossible?
Update
We got the Mac. ":D"
While there are things like FlashBuilder, these solutions don't provide the performance or flexibility of an actual native application. As for virtualizing OS X, this is not an option. The EULA for all versions of OS X specifically prohibit hardware virtualization (though I believe Lion allows for it but only when running directly on genuine Apple hardware. In other words, there is no way to run OS X on any computer other than a Mac without violating the EULA.
I dont have a Mac, but i setup a hackintosh (MacOSX running in pc) by following guide from this blog http://tonymacx86.blogspot.com/. If your pc spec is compatible, the Mac OSX will running flawlessly, just like in normal Mac.
Since you ask this question, I assume you dont want to fork a money to buy Mac, so setup a hackintosh machine is the best option for you. You just need to spend some money for buying legal copy of Mac OSX. Yeah I also setup the hackintosh in order to develop iphone apps on a pc.
Although there are always hacks and work-arounds you'll need a Mac for any serious iOS development. You can pick up a Mac Mini for under $1000, I'd be surprised if you could setup a Windows machine that could build iOS Apps for fewer than $1000 worth of man-hours... plus you'd probably end up having to constantly tinker to keep it working.
AFAIK, Mac OS X doesn't reliably run in a VM on a Windows Machine, but that could have changed since I last checked.
Most of the cross-platform development tools fall back to HTML/Javascript-based technology that is run in an embedded browser and packaged with a custom tool, I'd tend to avoid those as the Apps that they produce will not feel native.
I don't believe that Apple checks to see where the code was built. Adobe's FlashBuilder can export to an iOS binary, those Apps are accepted by Apple.
Creating them shouldn't be hard... testing them may be a little slow, but you'll definitely want to test on real hardware early and often.
If you get the Mac Mini you may hold option and click to simulate a dual touch in the iPhone simulator, but for more significant multi-touch testing you'll need to target a real device.
Depending on your goals, a web app may be a good solution. You'll potentially lose some performance, and some control, but you may not need all that much to accomplish your task.
My personal experience with IT has always been like pulling teeth to get them to allow/support any Apple product. Don't let them talk you into some patch work alternate system for making apps. Straight up OSX is far and away the best way to go, especially since you guys are talking about doing more later. Do it right from the start.
Now with adobe flashbuilder you can make iphone apps through windows http://www.adobe.com/devnet/air/articles/packaging-air-apps-ios.html it would all be coded in actionscript just like flash however looks pretty much alike. Personally I have never used it, i own a mac, but my school does cheers
Also I know you can put apps from this builder right into the app store just like the OS X process
You cant put it directly on a thumbdrive because OS X boots differently, you would need to install a new boot loader on you computer, but it can be done, look up Hackintosh
Finally , you do not need the magic touch pad, it is not possible to do multitouch while running on the simulator via OS X, you must put the app on your phone to test multitouch
Is there a legal way for a company to make iOS apps on Windows?
My advice is to try as hard as possible to get an Mac.
But just to provide another alternative :
Try Phonegap. It's basically a HTML5 wrapper, mainly used by app that needs to be published in multiple type of devices. However it also able to access native resource like camera and storage, which you can see in their feature page.
If your concern is more into development machine, by using Phonegap you can develop an app in any OS. You don't need to buy multiple mac for all the developer.
PhoneGap also have a service called PhoneGap build which is actually a cloud service that able to build your code to multiple platforms, including Iphone. This is legal and you can publish it App store.
If one of those ways is running OS X under a Virtual Machine... Is
it possible to do it with OS X Lion USB Thumb Drive?
No, You can only run OSX virtual Machine in OSX also.
Creating games on OS X (VM) would be hard?
It depends on the developer. But since the game should be tested in emulator, your question is not that relevant.
In the case we get the Mac (mini)... Would we need the Magic Touch or Magic Trackpad to test multi-touch? Or is only possible doing it by pressing one of the keys plus the left click?
Xcode Emulator able to simulate that. Read this blog
Creating Web Apps would be a solution? I know that we can't use the
Camera of the device using Javascript but is the rest ok?
If you are using PhoneGap, it's basically web apps wrapped by native. It's still give you access to resource like Camera, Compass, Storage etc.
Would you suggest to get the oldest generation of iPod Touch for
testing purposes or only the 3rd and 4th generation?
The iOS 5 SDK has many new features that make app development easier. By the time your app is ready for release, most users will have moved on to iOS 5. It is my understanding that iOS 5 does not support 3rd-gen devices, so there's no point in obtaining those if you're going to use SDK 5.

I've heard that you need to get a Mac if you want to develop iPhone apps. Is this true?
Is it possible to develop iPhone apps using Linux? If yes, what do I need and where do I download the necessary tools?
To provide a differing response, I'm running OS X and Xcode on a virtualised (VMware) machine on Linux. CPU is a Core2Quad (Q8800), and it is perfectly fast. I found a prebuilt VM online (I'll leave it to you to find)
Xcode/iPhone development works perfectly, as does debugging via USB to the phone itself.
It actually surprised me a lot - but I've had no issues at all.
The answer to this really depends on whether or not you want to develop apps that are then distributed through the iPhone store. If you don't, and don't mind developing for the "jailbroken" iPhone crowd - then it's possible to develop from Linux.
Check this chap's page for a comprehensive (if a little complex) guide on what to do :
http://www.saurik.com/id/4
It seems to be true so far. The only SDK available from Apple only targets the macOS environment. I've been upset about that, but I'm looking into buying a mac now, just to do iPhone development. I really dislike what they are doing, and I hope a good SDK come out for other environments, such as Linux and Windows.
Obstacles regarding the SDK:
The iPhone SDK and free software: not a match
Apple's recently released a software development kit (SDK) for the iPhone, but if you were hoping to port or develop original open source software with it, the news isn't good. Code signing and nondisclosure conditions make free software a no-go.
The SDK itself is a free download, with which you can write programs and run them on a software simulator. But in order to actually release software you've written, you must enroll in the iPhone Developer Program -- a step separate from downloading the SDK, and one that requires Apple's approval.
I think it's rather elitist for them to think only macOS users are good enough to write programs for their phone, and the fact you need to buy a $100 license if you want to publish your stuff, really makes it more difficult for the hobbyist programmer. Though, if that's what you need to do, I'm planning on jumping through their hoops; I'd really like to get some stuff developed on my iPhone.
There used to be a project dedicated to solve this defect: iphone-dev
The goal of the iphone-dev project is to create a free, portable, high quality toolchain to enable development for the Apple iPhone and other embedded devices based on the ARM/Darwin platform.
Regarding the alternative tool chain, Saurik's site is useful but for latest firmware development he indicates building on the iPhone itself and stays clear of indicating that you may need to copy necessary iPhone firmware files to your Linux environment. It's not impossible, but just requires additional work, especially for signing the code (there are open alternative solutions out there as well).
Also, take a look at other guides (for the same tool chain) that approach it more methodically.
I'd suggest to still do the final build and code signing and packaging in XCode (which may mean borrowing someone's Mac) in case you run into problems when submitting the application to Apple. Using the alternative tool chain opens up (at least on the Mac) the possibility of using other IDEs other than XCode for developing the application and again resorting to XCode for the deployment and testing with the simulator.
Of course if you do get the code signing / certificate generation working from the command line outside of XCode then you can install a certificate on your actual iPhone and test there (installing the app via iTunes w/your certificate).
The only way I know of doing development in Linux for the iPhone would be to install Vmware and work on getting OS X running in a virtual machine. With that said there are some "legal" concerns in doing that. It is reported that OS X Server can be virtualized but as far as the development story on that I don't know.
If you are truly serious, that's the what I'd investigate.
Good luck.
You can use Tersus (open source), and it lets you export the app as an Xcode project.
You might be able to write code on a Linux box that will eventually find itself on an iPhone or iPad, but ultimately you would need a Mac to test or deploy the code to the iPhone or to submit it to the App store. So ultimately you need a Mac, so you might as well do the work on the Mac too, with all the tools that Apple provide. There are alternatives to Xcode & Objective-C, such as Monotouch - but these utilize the Apple tools too.
You can with some work run OS X in a VM on Linux. However I should point out that this will break the OSX license agreement, even if you buy the copy of OSX - as it is only licensed to run on Apple hardware.
Sorry to give you this news - the ecosystem around the iPhone/iPad is very tightly controlled.
EDIT: One major exception to this is writing a web app for the iPhone. There are some excellent web apps for the iPhone which are almost as good as user experience as a native app. However I did interpret your question to be about native app development. Web apps, although the user can create an icon for launching them - are still 'second class' citizens.
I've had success building iOS apps on linux using the iOS clang toolchain by cjacker. Basically it consists of the upstream clang and llvm tools from your linux distro, a linux port of apple's linker and some extra tools to help simplify the build process (such as converting xcode projects to Makefile format).
It does take a few steps to install, but you're a software developer so you'd be used to that. I posted an up to date howto for Debian 7 (Wheezy) online:
https://rogerkeays.com/how-to-build-an-ios-toolchain-for-linux-debian-7
Otherwise you want to go with the generic instructions which are a little older:
http://code.google.com/p/ios-toolchain-based-on-clang-for-linux/wiki/HowTo_en
Good luck.
There's a framework called Rhodes.
The concept is based on Ruby on Rails and you develop your mobile app in Ruby and HTML, and you can write your code in a Linux environment. You can then create an account at Rhohub, where you add the code (through GitHub), and it allows you to compile it for iPhone, Blackberry, Android, Windows Mobile and Symbian, all off the same code. You don't have to code in Objective-C for iPhone, nor Java for Android, etc. It does the conversions for you. All you need to do is stick to the Rules for creating an iPhone application (or the Phone's you want to develop for) so it can be accepted at iTunes (or the equivalent market).
This will allow you to add the app to iTunes as well.
I have not found any emulators, however, which means that to test your app you need to put it on an iPhone, which is a mission.
I am using this option as I want to create apps for all phones and I use Ruby on Rails already. If you just want to make an app for an iPhone, then invest in a Mac.
Hope this helps.
You're right non-jailbroken phones are limited to Apple's App store and Apple "has the right" to enforce whatever rule, it's totally nonfree territory.
However while developing, one won't have to deal with Apple at all. You can use e.g. rsync to upload the code to the device and test it.
To a certain extent, yes, it is possible. You can type Objective-C code and set up your projects. You can even test the C and C++ parts of your code with gcc.
What you cannot do:
Use Interface Builder to set up your interface, as it's Mac-only. (Not required, but recommended.)
Compile code that uses Apple's Cocoa classes - they don't exist on Linux.
Test code in the Simulator - there isn't one for Linux.
Compile code for real devices or for the App Store - all this requires tools that Apple only provides for OS X.
You need to get mac for it. There are several tool chains available (like win-chain) that actually lets you write and build i Phone applications on windows. There are several associated tutorials to build the Objective C code on Windows. But there is a problem, the apps hence developed will work on Jail broken i Phones only.
We’ve seen few hacks to get over that and make it to App Store, but as Apple keeps on updating SDKs, tool chains need regular updates. It’s a hassle to make it up all the time.If you want to get ready app you can also take help from arcapps its launches apps at a reasonable price.
iphone app development
I did an attempt to port cocos2d-iphone to GNUstep so that you can Develop game based on cocos2d. However for publishing you need a mac. cocos2d-GNUstep.
I would recommend getting a mac because the ios simulator is amazing for testing in the early stages of an app. But I do know of a small company we work with that develops using Unity so they don't need a load of macs. That way they only need one mac for the office and that's just to compile the final build. It also means it works on android but it really depends on what your building because it's a games engine. You may want to look into web apps using frameworks like Sencha Touch Mobile
Unity: http://unity3d.com/
Sencha Touch: http://www.sencha.com/products/touch/
If you value your time, buy a Mac! I don't know enough about Linux development options to offer a viable solution, but it seems the proposed methods involve some pretty roundabout work. If you plan on seriously writing and selling iPhone apps, I think you could easily recoup the cost of a Mac Mini or Macbook. :-)
You will never get your app approved by Apple if it is not developed using Xcode. Never. And if you do hack the SDK to develop on Linux and Apple finds out, don't be surprised when you are served. I am a member of the ADC and the iPhone developer program. Trust, Apple is VERY serious about this.
Don't take the risk, Buy a Macbook or Mac mini (yes a mini can run Xcode - though slowly - boost the RAM if you go with the mini). Also, while I've seen OS X hacked to run on VMware I've never seen anyone running Xcode on VM. So good luck. And I'd check the EULA before you go through the trouble.
PS: After reading the above, yes I agree If you do hack the SDK and develop on Linux at least do the final packaging on a Mac. And submit it via a Mac. Apple doesn't run through the code line by line so i doubt they'd catch that. But man, that's a lot of if's and work. Be fun to do though. :)

iPhone: Software Development And Distribution

I have a few quick questions about the iPhone software development. I did some research about the topic, but there are a few specific things I would like to ask here, because I will have to estimate the cost of the required hardware and software, before I am allowed to buy anything. I never did any Mac development nor have I ever owned an iPhone, so needless to say this is quite hard for me.
I will buy an iMac mini with 2 GB RAM for iPhone development. I will have to use it at the same time as my regular PC, but the majority of the time I won't use the Mac at all. Do I have to buy an additional monitor, a mouse and a keyboard or is there a better solution?
I will have to port a C library to the iPhone platform and develop an iPhone application that uses the ported library. Do I need anything else than the iPhone SDK to do this?
If I use an external library (see above), can I test the application with the integrated emulator, or is it recommend to buy the device?
I will have to send data to a remote webservice. Aside from this I don't require any other features. Can I just buy the iPhone online from another country (the iPhones here are sim locked), or should I buy one with a contract?
When the application is ready, it will be installed on a few iPhones owned by our customer. Because of security reasons it is crucial that there is no third party involved in this process (i.e. the application should not be distributed on the app store). Is this possible?
If you don't use both computers at the same time it's perfectly possible to use the same monitor and keyboard / mouse for both computer
With the SDK you're set, also, you probably won't need to port the library since C is a subset of objective-C and your library will be available for use with the sdk right away.
The simulator can understand external library just fine
Countries like italy sell the iphone without a contract, you won't have any problem with those. Bear in mind that if all you need an iPhone with a camera then the 3g, 3gs and even the 2g will suit your needs, as all of those have cameras.
Yes, there's an option for distribution called "Ad hoc distribution". Using that you can install you app in your client phone without going thru the appstore

Is Android development restrictive in any way like for the iPhone?

Is Android development restrictive in any way like the iPhone, or can you download whatever and from whoever you want?
I want to learn about development for either iPhone or Android, but from what I hear iPhone development is pretty restrictive!
There are a variety of areas to consider regarding the relative restrictiveness of the two platforms.
The Market
Android Market is undoubtedly less restrictive than the App Store when it comes to the submission process. The upside is that you can get pretty much anything you want into the Android Market. The downside is that you can get pretty much anything you want into the Android Market (a market flooded with spam "applications" is in some ways a restriction).
A big negative on the iPhone side is the fact that your options for installing applications that are not in the App Store are limited -- you can either distribute the application as a beta (limited to 100 users) or jailbreak your iPhone. Android, however, allows you to install apps from anywhere, including a web page.
The Applications
One of the core design philosophies of the Android platform is "All Applications are Created Equal", which is supposed to mean that you can freely replace applications on the phone with a third party version. In practice this is not really the case, as many of the Google applications either have special capabilities not available to most applications (see: Android Market) or use undocumented/native APIs (see: Calendar).
The iPhone on the other hand makes no such claims about equality, and the Apple stance in general is "There is only one way to do it, and that is the Apple way". Additionally third party iPhone applications may not run in the background while Android applications can. New for iPhone OS 4.0 is the ability for apps to run in the background. One thing iPhone applications can currently do that Android applications can not is receive push notifications. New for Android 2.2 is the ability for apps to receive push notifications via something called the Android Cloud.
The Source
Android is open source - mostly (some firmware components are closed source). Even so, there is some rocket science involved just in getting the Android codebase to compile. In addition Google has sent cease & desist orders for redistributing custom images that include the Android Market and Google Maps application.
The iPhone is completely closed source, and recent changes to the developer agreement have been controversial as they mandate that all apps submitted to the app store be originally written in "Objective-C, C, C++, or JavaScript as executed by the iPhone OS WebKit engine, and only code written in C, C++, and Objective-C may compile and directly link against the Documented APIs"
The SDK
The Android SDK can be freely downloaded; the iPhone SDK requires free user registration to download. Android development can be done under Mac OS X, Windows or Linux, while iPhone development is only possible under Mac OS X. You'll also need to pay for the $99 iPhone developer account if you want to test your software on an actual device (rather than the simulator).
The Userbase
And last but certainly not least, the userbase. When this answer was originally written the iPhone had a much larger userbase and was growing much faster than Android. This is changing as Android begins to support multiple carriers and hardware platforms (see: the Open Handset Alliance). The list of devices running Android is now quite long although none yet match the popularity of the iPhone.
Some analysts are now reporting that Android is outselling the iPhone and are predicting that Android will soon overtake iPhone for market share. Other analysts think that Apple will make up ground when the iPhone 4g is released. The former seems more likely based on the parallel history of the PC industry -- Apple's design and user experience were copied by GoogleMicrosoft and opened up to run on commodity hardware.
Nope! That's the beauty of Android. Even though there is a AppStore equivalent, you can download an app from anywhere. Plus, it's programmed in Java, so you don't have to worry about all that mundane stuff like garbage collection (just at the cost of speed).
Don't mean to insult the iPhone. It is a great platform too.
EDIT: A lot of people have been noting that the iPhone APIs are not restrictive, but rather the approval process is. This is true, however the iPhone's APIs are still somewhat limited, in the way of low level hardware access, backgrounding (only notifications in 3.0), etc.
iPhone 3.0 is a step in the right direction, but there is some work left to do.
Also, have you considered making JB iPhone software? I'm not sure of it's market share, but I do know of a lot of people with Jailbroken devices.
EDIT: I have read in some more posts on similar questions that Android's Java can slow things down due to the Garbage Collector. Just something to watch out for.
If you say iPhone is restrictive, I would describe Android as immature.
There are still many bugs in Android that you will inevitably run into if you are doing some none-trivial programs. Some of those only exist on the emulator while others only on the actual phone.
Though in my experience, developing on Android with Eclipse feels just as good as developing on iPhone with Xcode, if not better. The tool set provided by Google is very complete and is cross-platform. Garbage collector does make huge difference while programming.
I'm assuming you already have a Mac otherwise the iPhone wouldn't be an option at all.
iPhone development isn't particularly restrictive. Getting the resulting app on Apple's App Store is the restrictive part.
If the app you're working on follows Apple's guidelines on what an iPhone app is allowed to do, picking that as your initial development platform seems a no-brainer. If it violates Apple's guidelines and can't be modified to follow them, your market will be restricted to jailbroken phones - a very small subset.
Well is Apple open at all? Uhm.. eh.. no. Closed hardware, closed software, closed everything. I think Alcatraz is more open then Apple, at lease you get to leave your cell there.
You can write an application for the iPhone. Will it get approved? Well not sure. They could deny it for any reason whatsoever. You may have used a blue background and Apple only likes white and gray, thus deny.
However with Android it is completely open. You can develop for it, or even develop Android itself. No fear of ever being denied.
But in all seriousness. Apple has a larger market share, millions of people use and love the iPhone and they will most likely not be leaving for quite a while. While on the other hand the Android was for T-Mobile. Does anyone even use T-Mobile?
IMO if you do not have a gPhone I would develop for the iPhone. However as much as I dislike the Apple philosophy of being such a closed nature, they are the better bet if you wish to make some money with your application.
There are some restrictions...
some functionality requires rooted phones (e.g. Wireless Tether for Root Users)
distribution via the Android marketplace is subject to the Developer Distribution Agreement. Google limited access to this tether app due to their carrier agreements.
some Android APIs are not finished (e.g. Bluetooth HID)
'Restriction' can mean two things:
The ability to install anything you want. Google is very good at that, Nokia somewhere in the middle and Apple is the worst
What you are able to do with you app. They all have arbitrary restrictions on what you can and can't do, but it seems to me Nokia is the least restrictive, Google inbetween and Apple the worst (again).
YMMV
No, you can sign the application yourself and distribute the resulting APK file via your own web server or by other means.
Yes, Android is indeed open and you can publish whatever you'd like to the Market Place
But:
you still need to learn how sign your application and mind the technical posting requirements to the market (like keeping proper version IDs etc.)
if you really want to get/send a package from/to anyone, then the receiver of the package (called an APK file will need to know how to use a command line tool called 'adb' to administer their phone to install & uninstall applications. It's pretty simple to do, but
you need to have Android drivers installed and the SDK tools.
To be fair to the iPhone development model, you can also distribute test versions of your application reasonably easily, though perhaps not as easily as with Android. Your testers need to provide you a special device ID which they get from iTunes while the device is connected, then you create a license file containing keys for all of your testers which you distribute with the release directory of your application. The users then install your application via iTunes.
In most cases no, but Google has allowed the carrier and the device manufacture the ability to restrict certain things. Carriers are allowed to block individual apps. Also carriers/manufactures can prevent certain features of the device.
One example is the Motorola Backflip, it wont let you install non Official market applications. Also some phones do not have access to the Official Market.
