Hi im still not 100% with xcode and android. I have the Droid X and I code with Xcode. My dad is on the Fire Dept. and wants me to code an app for either the android and/or iphone that detects the dispatch's radio signal and receives it and streams it in the background so the firemen could listen to the radio on their phones so they wouldn't have to carry their bulky radios with them everywhere. If there is someone that could help me or point me in the right direction, I would greatly appreciate it.
Thank you, Halokllr
Some bad news Halokllr, the iPhone doesn't have a radio chip, and the FM radio included in some Android models will probably not be able to physically pick up emergency broadcast signals. In order to do what you are suggesting, you would need a web service of some kind that already exists and streams audio for the emergency signals you're interested in. Now there ARE some services like this, though I would strongly suggest that if it is intended to be used for actual first responders that you very carefully research their timeliness guarantees. Some of them may be hours behind live events. Check out http://www.radioreference.com/ as an example service provider.

I have a question, I want to buy a beacon and send the signal from the beacon to the flutter application and then do something.
Is that possible with flutter?
Thank you very much!
Yes, it is possible. I tried https://pub.dev/packages/flutter_beacon for myself interest once when covid-19 declared a pandemic by WHO to solve Handshake problem.
I was converting the existing device as a beacon and then used "flutter_beacon" package to get the list of beacons in a defined region. So yeah, it is possible to do it flutter also. You can customize it as per your need further. But basic things are possible like getting the list of beacons in reason.
If asked whether or not, the answer is yes. but there are some obstacles or limits, such as Bluetooth will not scan in the background as in this article, this is indeed from Android and IOS which causes the limit. I am also working on this project, but there are still some problems as I have described above.
This link also can help Beacon scanning in background - Android O
I shake my iphone headphone jack and it changes the song on my nano iPod 7th gen and I move it in circles and it also changes the song or pauses it I take out lint get still does it I don't understand is it programmed to act this way I use any other headphones doesnt act the same way I've already used two iPhone head phones still does it if the headphones aren't Apple related it won't do it
Are your headphones the kind with a build in mic/controller? I had a similar issue happen to me with my iPhone recently - it was to do with a poor connection or fraying within the headphones themselves. After trying a new set, the problem stopped. If as you say it only happens with one set of headphones - the issue is likely the headphones, rather than the iPod/iPhone.
Check also that the headphones you have are designed for use with Apple devices - it seems a bit much, but recently with more functionality being allowed via a simple interface, different manufacturers (ie: Samsung/Apple) have different standards for how they treat different events from this controller.
Finally - note that this is a community site for developers - aspiring and professional alike (I fall into the former at the moment!). your question perhaps may be better suited to the Apple website forums, rather than here. Hope this helps all the same.
I need to develop an App witch detects voice when it´s running (not what are they saying, just if someone speaks) and if so, I need to launch an especific mp3 from my sd.
I never developed for android/iphone but I need to especify my boss in how many hours it could be done.
Is there any easy way for voice recognition? and... I think that the answear could be yes but, is ther a way to listen a specified mp3 from my code?
(no plataform specified yet, it could be android or iphone)
Thanks very much in advance
Try looking at this question. It might help a bit. if you got back something valid from the google servers, then you could cause it play an MP3, I suppose.
EDIT: Also, it's important to remember that android phones don't do the "voice recognizing" themselves. The sound is streamed to Google servers (like a phone call) and the servers "recognize" what you're saying, and send that back to the phone.
I am working on an app for the iPad and would like to be able to include the option to use a separate iOS device to control it. I have seen examples of this with games (notably Chopper 2), but have no idea how it is done.
Can anyone point me in the direction of the iOS frameworks that back this feature? I have looked through the SDK but cannot find the relevant sections.
Thanks
Im sure they use Game Kit or you could use the lower level Bonjour discovery.
Read through the GameKit docs.
You can start there. I guess the controller is actually a separate feature of the app that just sends messages over the network, using sockets to send and receive the data.
Send over the network from the controller. Receive them on the ipad in a running thread or however the service you use handles it. process the received messages.
Agreed with #alJaree. I'm working on something similar, though I've found it much easier to implement through Unity. Prime31 has a number of sweet plugins that allow you to implement things like Bluetooth through gamekit in a single line of code. I'm on my ipad right now so I cant be sure of the exact URL, but I think it's just prime31.com, in their 'unity' section.
Which of the new features are you looking forward to the most in iPhone SDK 3.0?
Is it one of the main advertised six new things, or something smaller? Something in the "1,000 new APIs", perhaps?
Phone to phone communication via bluetooth seems like it will terribly useful for some apps I am writing. No longer do you have to input all the data you want to store yourself, you can share some of it with other iPhone users.
not really a feature, but the best thing about developing the iPhone SDK further is the great frameworks that arise. there are some really, really great frameworks out there already (like the Three20 project) which will become even better with the new 3.0 SDK.
my real excitement will take over once they let us run background processes. maybe in 4.0?
Video! The ability to write decent tools for mobile video uploads is a big draw.
MapKit by far will bring the biggest change sweeping across the app space.
My personal favorite is that we can finally easily track upload progress of large files (like images).
I really, really want to see fixes in the camera API so that it isn't either broken (2.2.1) or forcing a switch to portrait (3.0).
Apart from that, the most useful features to me are:
push notifications. Great for making an app more sticky - you can let the user know that something of interest to them has happened.
CoreData - I've been using a third-party SQL layer, but it's a little buggy and no longer supported.
Peer-peer bluetooth, as the poster above said, is also useful for local data exchange.
And the least useful? Cut and paste. I actually want to disable it in my app (to discourage people from copying content) - and it doesn't look as though you can (yet).
Bluetooth phone-to-phone communication with GameKit will enable a host of currently impossible applications. Multiplayer games with no WiFi network needed and data exchange between two phones are obvious use-cases.
I'd also like to see - not currently included in the betas - a decent camera API that allowed us to customize the appearance of the capture screen, and as another poster said, have it work properly in landscape and portrait mode.
