Answer 1

Did you try using wake-locks? Generally app will wake up on the receive of broascast butif it doesnot (happens in few devices), then try using wake-locks which will forcefully wake up the device.

How to use wake-locks :

//Register for wake-locks

if (mWakeLock == null) {
        PowerManager pm = (PowerManager)yourcontext.getSystemService(Context.POWER_SERVICE);
        mWakeLock = pm.newWakeLock(PowerManager.PARTIAL_WAKE_LOCK, yourcontext);
        mWakeLock.setReferenceCounted(false);

}

//Apply wake-lock using acquire

mWakeLock.acquire();
