Removing Title in Android Application

In onCreate function:

Between ;

super.onCreate(savedInstanceState);

and 

setContentView(R.layout.activity_main);

add these codes:

//Remove title bar this.requestWindowFeature(Window.FEATURE_NO_TITLE); //Remove notification bar this.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);

Worked for me ;)
