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.

I need to create a radio app in android using a radio frequency (without internet).
So, when doing some re-searches, I found all samples using streaming.
Can someone tell me some If we can create the radio frequency android app without any internet connection?
There is no specific API to access FM Radio. All the source codes are proprietary. But you can find some reverse-engineered code or library for specific devices on google.

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 work on an indoor tracking project using android.I used Gps to detect location but it does not work correctly at indoor tracking
How can I solve this problem?
If you GPS signal is bad there are 2 things you can do.
One is: improve you reception (e.g. remove the roof, good outside, replace roof with glass). Now this might be a little ... tricky
The other one is: use a different technique. Bluetooth tracking (BLE beacon) for instance.
You cannot 'amplify' GPS signal. The system works by finding out how long it takes a singal to go from several satallites to your phone. If you 'repeat' or amplify the system it is going to give false results. So you can not do stuff like "put an antenna on the roof", as all your locations would return the location of the antenna.

I am trying to get signal strength readings from existing access points within a given room without having to connect to them. I am very new to android development and eclipse so I would really appreciate it if someone could give me some direction in this matter.
}
Register a BroadcastReceiver for SCAN_RESULTS_AVAILABLE_ACTION
Start scanning using wifiManager.startScan()
In the receiver's onReceive(), get the results using wifiManager.getScanResults()
Loop the result, and get scanInfo.level
A similar example can be found here. I won't implement that into your class, because you should learn something. If you don't manage to implement your class, you should get yourself more knowledge on Android programming before starting such a project.

I understand that Google used a wardriving kit in its Street View cars to bootstrap its map of wifi beacon landmarks.
But which data sources and methods do they use to discover and register new access points? Will they only feed in new BSSIDs submitted my Android phones with a valid GPS fix?
I set up two new APs (one of them dual 2.4/5GHz) and within two weeks Google had a fix for them, albeit 290m away from the real location. I will see if this fix will become more precise with time.
I’m fascinated by this but I didn’t find more details about how they do it.
