How to grant MODIFY_PHONE_STATE permission for apps ran on Gingerbread

Question

I write an application that attempts to modify phone call state. It works well on Android 2.2 or less, but throw an exception on Android 2.3 because of the lack of permissio

Answer 1

Try this.

public static void answerPhoneHeadsethook(Context context) {
    // Simulate a press of the headset button to pick up the call
    // SettingsClass.logMe(tag, "Simulating headset button");
    Intent buttonDown = new Intent(Intent.ACTION_MEDIA_BUTTON);
    buttonDown.putExtra(Intent.EXTRA_KEY_EVENT, new KeyEvent(KeyEvent.ACTION_DOWN, KeyEvent.KEYCODE_HEADSETHOOK));
    context.sendOrderedBroadcast(buttonDown, "android.permission.CALL_PRIVILEGED");

    // froyo and beyond trigger on buttonUp instead of buttonDown
    Intent buttonUp = new Intent(Intent.ACTION_MEDIA_BUTTON);
    buttonUp.putExtra(Intent.EXTRA_KEY_EVENT, new KeyEvent(KeyEvent.ACTION_UP, KeyEvent.KEYCODE_HEADSETHOOK));
    context.sendOrderedBroadcast(buttonUp, "android.permission.CALL_PRIVILEGED");
}
