Could someone please help and implement this? I would appreciate and it and it would help a lot. Also, I have even helped myself by trying.

You need to use the TelephonyManager
mTelephonyMgr = (TelephonyManager) getSystemService(Context.TELEPHONY_SERVICE);
mTelephonyMgr.listen(mPhoneStateListener, PhoneStateListener.LISTEN_CALL_STATE);
The listener object can be created like this
private PhoneStateListener mPhoneStateListener = new PhoneStateListener() {
#Override
public void onCallStateChanged(int state, String incomingNumber) {
// Test for incoming call, dialing call, active or on hold
if (state==TelephonyManager.CALL_STATE_RINGING || state==TelephonyManager.CALL_STATE_OFFHOOK)
{
stop(); // Put here the code to stop your music
}
super.onCallStateChanged(state, incomingNumber);
}
};
When stopping, or closing your app, remember to call this.
mTelephonyMgr.listen(mPhoneStateListener, PhoneStateListener.LISTEN_NONE);

How to connect multiple clients to one host via Wifi P2P

I'm trying to create a WiFiP2P to communicate with 2 android phones and one Raspberry Pi. I want one phone as host and the second phone + Raspberry Pi as clients.
Until know i could create a test APP to connect the 2 phones via Wifi direct (tested successful). I was following a great tutorial on Youtube Wifi P2P. Unfortunately the tutorial just show how to connect one host with one client and not multiple clients.
I was trying to follow the Android developer guide, but I have not enough experience to understand everything.
I hope you guys can help me to understand what I have to change in my code and explain me why.
The following code is the exact copy from the mentioned tutorial.
Here my MainActivity:

Running My App In The Background

I have tried to get this working so that it plays in the background?? why won't it work it looks fine to me??
I am new to java/android development so hope someone can fix the issue and explain what I problem was so I can learn something
Yes I got it to stream so far but once you exit the app the music stops playing
For being new think im doing great must be since I have previous experience with PHP etc..
Thanks ;)

well, it is stopping because you're asking it to stop.
When the activity goes to background it pauses.
You should run the stream from a service (that stays in the background without issues) and use a bound service to communicate between activity and service http://developer.android.com/guide/components/bound-services.html

Stop App On Incomming Phone Call?

How would I stop music playing so call the OnPause if there is a incoming or outgoing call?
So once there is a call or they make a call it will stop the music by calling OnPause.

how would I stop music playing so call the OnPause
onPause() and onStop() are lifecycle methods that will be called automatically; you do not call them manually. You should override them and add your code that would stop the music.

You don't need to do anything in your lifecycle methods to stop the music. Android provides you with a mechanism to handle these cases.
The mechanism is called Audio Focus. Apps request Audio Focus when they want to play audio (or video!). When another app needs audio, it requests the Audio Focus. And the subscribed parties receive a broadcast saying: Hey, you've lost the audio focus. If the focus was only temporarily lost (like when a notification comes and it plays a short audio beep) then the Broadcast says: Hey, you've lost the audio focus but duck the audio, I'll give it back in a moment.
The idea in that case is that you lower (duck) your volume to 0.1 (for example) to let the other sound (beep) be louder.
After the "beep" from the notification is done, the broadcast says: hey, here's the audio focus you had earlier.
At this point if you're still playing, you'd restore the volume to what it was before.
That's the concept behind audio focus. It's perfectly explained in the Android Docs (and the Android Samples) albeit the Google code is rather messy and inconsistent, it does work out of the box. They do a lot of crappy abstraction and some strange code practices but irregardless of that, the code works fine.
The same goes for a phone call, you subscribe to it and tell your service to pause/resume the sound when there's a call in progress. Not when your app goes to the background (onpause) because that's unreliable and doesn't mean at all that you app went to the background.
Here's the Android Official Docs for Audio Focus.
