This can be done by acquiring a Wake Lock.

I didn't tested it myself, but <a href="http://android.voxisland.com/code_examples/How_to_stop_screen_from_dimming_by_enforcing_wake_lock.rhtml" rel="nofollow">here</a> is a small tutorial on this.

In a View, in my case a SurfaceView subclass, you can set the screen on always on. I wanted the screen to stay on while this view was still drawing stuff. 

<pre><code>public class MyCoolSurfaceView extends SurfaceView { 
@Override
protected void onAttachedToWindow (){
 super.onAttachedToWindow();
 this.setKeepScreenOn(true);
}

@Override
protected void onDetachedFromWindow(){
 super.onDetachedFromWindow();
 this.setKeepScreenOn(false);
}
</code></pre>

1.getWindow().addFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);is best solution for Native Android. 
2. if you want to do with React android application then please use the below code. 

<pre><code>@ReactMethod
 public void activate() {
 final Activity activity = getCurrentActivity();
 if (activity != null) {
 activity.runOnUiThread(new Runnable() {
 @Override
 public void run() {
 activity.getWindow().addFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);
 }
 });
 }

 }
