MyAs mentioned in the comments of your question, you can use service.

Alternatively, I guess it can be done in Activity with the use of wakelock too. Acquire a partial wakelock in your activity. This way, the CPU wont go to sleep and your activity keeps running.

For acquiring wakelock:

PowerManager pm = (PowerManager) getSystemService(Context.POWER_SERVICE);
PowerManager.WakeLock wl = pm.newWakeLock(PowerManager.PARTIAL_WAKE_LOCK, "My Wakelock");
wl.acquire();

For releasing wakelock:

  wl.release();

You can acquire wakelock when your activity is created and release the wakelock when the activity is destroyed.
