Can APP send device data(e.g. accelerometer gyroscope proximity sensor) to the server in the background?
Yes, it is possible to send data in background. In Android, you need to use a service for that type of application. Here you can find a more complet answer.
But be careful with that. It is not a good practice because running the sensors continuously like that would drain the battery quickly.

I am trying to write a program that analyses the analogue audio content of an incoming call on an Android device - i.e. frequency / amplitude.
I have been looking at ways of trying to do this using Android Studio, but can't see anything obvious, any ideas on this would be really appreciated, thanks

Am new to android ,i want to create an android app to track indoor position using ips(wifi signals)
I need to know what are Prerequisites required for and the basic idea to develop it
You must have:
1) some wiFi antennas working around (minimum three to have the precise position in the room);
2) you must use your Wifi and check the power of each antenna.
Depending on the variations of these three levels of power, you can understand where you are. This is called triangulation.

Can an Android app (runs on background and uses Spotify SDK) get info of which track the user listens currently at exact time in Spotify Android app?
I think you'd be interested in the Android Media Notifications.
If you are developing an Android application and want to know what is
happening in the Spotify app, you can subscribe to broadcast
notifications from it.

I am looking to write an app that is aware of what music the user is listening to (in any other app). Does the Android SDK allow for this?
I know that MediaPlayer objects are generally used, however they seem to be created within the context of the specific app...
Any ideas?
Thanks
Most music apps will send out metadata about songs/tracks that are playing.
You may want to look at using a BroadcastReceiver

Can anyone tell me where to search for the following?
I'm trying to create an application that allows the user to schedule an SMS to be sent at a specific time.
I can do this when the application is open and running but I want my application to work even if it is not running, using a service for example.
Can anyone tell my where can I find any resource for doing that?
U will need to use WakefulBroadcastReceiver to achieve this see this example
