Android Display How to stop screen from dimming by enforcing wake lock?

Enforcing a wakelock is sometimes necessary but should be used with caution as it will take it's toll on the battery. 

import android.app.Activity;

import android.content.Context;

import android.os.Bundle;

import android.os.PowerManager;

public class DoNotDimScreen extends Activity  {

 private PowerManager.WakeLock wl;

 @Override

 protected void onCreate(Bundle savedInstanceState) {

  PowerManager pm = (PowerManager) getSystemService(Context.POWER_SERVICE);

  wl = pm.newWakeLock(PowerManager.FULL_WAKE_LOCK, "DoNotDimScreen");

 }

 

 @Override

 protected void onPause() {

  super.onPause();

  wl.release();

 }

 @Override

 protected void onResume() {

  super.onResume();

  wl.acquire();

 }

}

You will need to include this permission in your manifest:

<uses-permission android:name="android.permission.WAKE_LOCK" />
