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.

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.

Android has Mouse support and I wonder if I can control a "virtual mouse" via service/app. I did a lot of research but I do not think the sdk provides anything I can use for obvious security reasons.
I wonder if anyone could give me a hint how to achieve this with root permission.
If android phones can run a VNC server this should be possible too shouldn't it?
I want to send the movement of a computer mouse to the phone. A cursor should be shown like if you connect a bluetooth mouse.
Thank you
