Full screen activity/application
Set your android application on fullscreen view, removing the default Android task bar and the application title bar. We have two choices: editing the Activity with Java code and the other one is edit the Activity from the manifest file.
// YourActivity.java
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);
getWindow().setFlags(
WindowManager.LayoutParams.FLAG_FULLSCREEN,
WindowManager.LayoutParams.FLAG_FULLSCREEN);
setContentView(R.layout.main);
}
<!-- AndroidManifest.xml -->
<activity android:name=".YourActivity"
android:theme="@android:style/Theme.NoTitleBar.Fullscreen" />
