Answer 1

First do the following :

try {
        Thread.sleep(1000);
    } catch (InterruptedException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }

then call the abortBroadcast() method before calling your activity and make sure to put a priority in your intentFilter like the following :

 <intent-filter android:priority="99999" >
            <action android:name="android.intent.action.PHONE_STATE" />
  </intent-filter>

and to answer the incoming phone call from the custom UI do the following :

answerButton = (Button) findViewById(R.id.pickup);
    answerButton.setOnClickListener(new OnClickListener() {
        public void onClick(final View v) {
            Intent answer = new Intent(Intent.ACTION_MEDIA_BUTTON);
            answer.putExtra(Intent.EXTRA_KEY_EVENT, new KeyEvent(KeyEvent.ACTION_UP,   KeyEvent.KEYCODE_HEADSETHOOK));
     context.sendOrderedBroadcast(answer, null);

        }
    });

and to reject the call do the following :

rejectButton= (Button) findViewById(R.id.pickup);
    rejectButton= .setOnClickListener(new OnClickListener() {
        public void onClick(final View v) {
            Intent buttonDown = new Intent(Intent.ACTION_MEDIA_BUTTON);
    buttonDown.putExtra(Intent.EXTRA_KEY_EVENT, new KeyEvent(KeyEvent.ACTION_DOWN, KeyEvent.KEYCODE_HEADSETHOOK));
    getApplicationContext().sendOrderedBroadcast(buttonDown, "android.permission.CALL_PRIVILEGED");


    }
});

Hope that helps
