I have seen several examples of how to implement a BroadCastReceiver, but how should I implement a Service that has to react to some pending Intent (for example incoming phone call)... Actually I was wondering about the same "problem" but in an Activity.. You obviously have a class which extends a Service or an Activity) so it cannot also extend BroadCastReceiver... It looks like we cannot make "platform-aware" services and/or Activties?
you can create an inner class
class A extends Activity {
BroadcastReceiver r = new BroadcastReceiver(){
// code to handle broadcase
}
}
that class will receive events, which you can pass to main handler, or just call some outer methods
Actually you can react to incoming phone call just by adding listener to TelephonyManager
You define PhoneStateListener in your Service/Activity
private PhoneStateListener mPhoneStateListener = new PhoneStateListener() {
@Override
public void onCallStateChanged(int state, String incomingNumber) {
super.onCallStateChanged(state, incomingNumber);
switch (state) {
case TelephonyManager.CALL_STATE_OFFHOOK:
break;
case TelephonyManager.CALL_STATE_RINGING:
break;
case TelephonyManager.CALL_STATE_IDLE:
break;
}
}
};
Then in onCreate method:
mTelephonyManager = (TelephonyManager) getSystemService(TELEPHONY_SERVICE);
mTelephonyManager.listen(mPhoneStateListener, PhoneStateListener.LISTEN_CALL_STATE);
Finaly you clear the listener in onDestroy:
mTelephonyManager.listen(mPhoneStateListener, PhoneStateListener.LISTEN_NONE);
So much simpler in this case.
