When Android 5.0 plays music, the alarm clock rings, and the phone calls and hangs up, and the alarm clock and music ring simultaneously.

Please follow the steps below to modify it:
Frameworks\base\media\java\android\media\mediafocuscontrol.java:
1, Import Packages:
Import Com.android.internal.telephony.ITelephony;
Import Android.os.ServiceManager;

2, increase the access to the current phone call state method Getphonecallstate ():
private int getphonecallstate () {
int phonecallstate = Telephonymanager.call_state_idle;

Telephonymanager Telephonymanager = (telephonymanager) mcontext.getsystemservice (Context.telephony_service);
Itelephony Telephonyservice = ITelephony.Stub.asInterface (Servicemanager.getservice (Context.telephony_service));

if (telephonyservice! = null) {
LOG.W (TAG, "Getphonecallstate:mtelephonyservice! = null");
try {
Phonecallstate = Telephonyservice.getprecisecallstate ();
LOG.W (TAG, "getPhoneCallState:telephonyService.getPreciseCallState () =" + phonecallstate);
} catch (RemoteException ex) {
if (Telephonymanager! = null) {
Phonecallstate = Telephonymanager.getcallstate ();
LOG.W (TAG, "getPhoneCallState:telephonyManager.getCallState () =" + phonecallstate);
}
LOG.W (TAG, "Catch exception when Getprecisecallstate:ex ="
+ ex.getmessage ());
}
} else {
LOG.W (TAG, "getphonecallstate:telephonyservice = = null");
if (Telephonymanager! = null) {
Phonecallstate = Telephonymanager.getcallstate ();
LOG.W (TAG, "getPhoneCallState:telephonyManager.getCallState () =" + phonecallstate);
}
}
LOG.W (TAG, "getphonecallstate:phonecallstate =" + phonecallstate);
return phonecallstate;
}

3. Modification
Private Boolean Canreassignaudiofocus () {
Focus requests is rejected during a phone call or when the phone is ringing
This was equivalent to in_voice_comm_focus_id have the FOCUS
if (!mfocusstack.isempty () && Mfocusstack.peek (). Hassameclient (in_voice_comm_focus_id)) {
return false;
}
return true;
}
