Question

I develop an android application and I need to prevent the user to close the application from navigation bar buttons .. there is another way to close the application. I search a lot and didn't find any way to Permanently hide bottom navigation bar or at least stop all button control

Answer 1

If you meant to disable the back button on device, you could override

@Override
public void onBackPressed() {
    super.onBackPressed(); //delete or comment this line
    .......//do something you want
}

Answer 2

Use this method to disable the Home button

@Override
public void onAttachedToWindow() {
    this.getWindow().setType(WindowManager.LayoutParams.TYPE_KEYGUARD);
    super.onAttachedToWindow();
}
