Full Screen without navigation & status bars
If there are still spaces for the system bar and navigation bar even under immersive mode. Make sure the splash imageView is not in a FrameLayout that insets it. If it is do this i.e. set android:fitsSystemWindows = "false"
<FrameLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="false">
What you need is called Immersive Full-Screen Mode.
// This snippet hides the system bars.
private void hideSystemUI() {
// Set the IMMERSIVE flag.
// Set the content to appear under the system bars so that the content
// doesn't resize when the system bars hide and show.
mDecorView.setSystemUiVisibility(
View.SYSTEM_UI_FLAG_LAYOUT_STABLE
