I have built an enterprise app and now i have an update coming up for this app. Now, how do i make my clients install this app? I read it here but just want to make sure that it works and want to know if i have to take any precautions or anything which i need to do before i send the updated app to my clients?
Anyone who has done this or who has an idea about this, please help me out!
if someone updates application then their document folder will remain as it is. so make sure that those existing data is not affecting your new version and if you want to retain some old data then keep same bundle identifier and ask user not to delete application.
Best way to test this is make a local server setup, then install old version, then update it with new version and test it again.
setup of local web server will not take more than 20 min.....
Hope this is helpful....

I recently found that Facebook App (for Android & iOS, but i'm using Android anyway) downloads almost all friends' information (including FB ID and real e-mail account) to a SQLite database called fb.db. I am trying to do the same thing programmaticaly (using python, perl, bash etc) but with no luck so far. I need a way that will do similar requests with FB APP, and will download all of my friends' info upon login, just like the way FB APP work.
I tried so far to:
Decompile com.facebook.katana and see how it's done - No luck (or just missed it).
Sniff the facebook app with burp - No luck (due to SSL and app's protection when certs have been changed)
I am sure you went through this: http://developer.android.com/guide/topics/data/data-storage.html#db
There it is stated:
Android provides full support for SQLite databases. Any databases you create will be accessible by name to any class in the application, but not outside the application.
It was not the answer, it was just a text, which states that you can create a database for your web app. But unfortunately they are not providing any kind of helping material about writing and removing the data from that Database. So lets move to another source!

How to insert data into SQLite database in android?
There is a sweet example of how to add the content to a database in Android.
There is another example on this question too, Downloading data/content into Sqlite database
Why they didn't work:
Decompiling won't work! As they might have editted the app to be only fb-developer-readable on the first place. So you will never have success this way.
And the second thing is same.
All you can do, is to guess the algorithm or ask for it here: http://programmers.stackexchange.com and give it a try from scratch! :)
Suggestions:
I would try to recommend you to first learn how to:
Access Data connection on the phone.
Access the server from where to download the data.
Create a string or what ever data type to be inserted in database.
Create the connection, and save the data there!
I would now assume that you are a beginner, and want a tutorial! Then the first guess could be to visit their own project sites (SQLite, Android). Visit the developer network. And look for what you get!
Good luck buddy! Cheers.
I have very little knowledge about app development, but I am updating an existing SQLite database (simple text changes to the html that is stored within the database). Everything works fine, but when I submitted the app to Apple the changes weren't showing when people upgrade (if you download it for the first time - straight from the App Store - it is fine, so the database must be saved to the cache).
Does anyone know how I can overwrite the existing database? People have said to change the file name of the database, but will this make the app run slower (will two databases be stalled in the cache). Also peoples data are stalled on the database (bookmarks etc.) so somehow that info still needs to be retained if possible.
Any help would be appreciated.
i also would recommend you to rename the database. thats the easiest and fastest way. rename your model and set it to the standard.
i am using this solution, too. my app is not running slower then before. just test it.
please also see this two links for adding new models to your project:
create new model version(apple)

I think that change should happened only in the build u r tested and not in you have uploaded on appstore.
So better way u upload it again... With all testing done.
I want to create an application in which i want a login logout authentication from the database file that can be handled by web services. This application should always need to be connected with the internet and after login i need to upload images and also give there views about the image and i am not getting any idea how start work on that can anyone help me.... I want to use this application some sort similar like facebook.
There is also a problem that which type of application i create native or web or else. Please help me to start this application.....
Try setting up a server that can handle the requests from your app. Your app can then request content or upload content to the server using NSURLRequest. For further reading refer http://developer.apple.com/library/ios/#documentation/Cocoa/Conceptual/URLLoadingSystem/Concepts/URLOverview.html
I think you are asking the wrong question. What web development language do you know to help you accomplish this? There are many different ways to go, like open source as opposed to paid, which services best handle your specific needs, like Ruby or PHP, which RDBMS to use, etc. If you don't know any programming, then it is going to be a long road. Your first step should be taking what you already know and branching from there, learning what you need to know. In your case, you'll need to learn server side scripting, connect it with a database, how to set up a server to put it all in, as well as client side development like javascript to go with the html.
I hope that my title is descriptive enough. I am planning on creating a directory application for my town however I would like to to be a fully offline experience.
The idea would be to offer businesses a yearly subscription for listing their business in the directory.
My concept would be to create a web interface where they can pay for their subs and then enter all of the information into a their profile listing that would then be saved into a sql db.
I am wondering if it is then possible to take this sql database and then use it in the application by saving it into the application directory some how.
Basically my question is how could I do something like this? what is the best way to get them to enter their own information then me somehow build that database into the application?
Its not certain that I will even end up doing this but I am just really intrested in how to generate my own content for application like this that I can then use strictly offline.
Any help would be greatly appreciated
In my opinion , need to create some web application that provide information each specific client and client need to sync some update information with server and do caching.
If there is no need to update , use your cache . and If there are something to update . try to decide what is need to update and show them.
hope it helps you
I have an app on the App Store that needs to have its resource data files updated periodically (every 2-3 months). So far, I've just been deploying a new version of the app to the App Store every time I need to do this, but the fact that I have to wait a week or two for the changes to become live is cumbersome.
Theoretically, I was thinking of creating a new "version_control.txt" resource file which tracks the version numbers of every other resource file. Periodically, the app would check its version_control.txt against a version up on some web server, and then download any files that need to be updated.
Do there exist any frameworks or SDKs to handle all of this for me, or do I have to write everything myself? Is there a better solution?
You can't update the resources in your app bundle without updating the entire application. However, there's no problem with having your app retrieve resources from a web server and save them in your app's Documents folder. From there, it's simple to have the app look for its resources in the Documents folder before looking in its own bundle.
I don't know of any frameworks that manage resource versions for you. There's not a lot of work involved, and each app likely has its own requirements, so I'm not sure that a framework would help that much. If your web server supports it, you could request the resource file(s) each time your app runs, but add the if-modified-since header so that you only download a new copy if the version on the server is newer than the one your app already has.
I also had similar problems. I had tried to download some custom files from my ftp domain but that really didn't work very well. Not only I had to pay for the bandwidth, the users weren't very happy about it. The coding complicated considerably. Now, I've decided to update periodically via AppStore. The users are more satisfied since they see updates, but they don't understand is that only a couple of resources have been updated.
PS: I'm not aware of any SDK or framework for it. But you don't need it, you just need to download some files...
