IllegalArgumentException: Window type can not be changed after the window is added

Question

I\'ve tried the advice here, the advice here, the advice here, I\'ve commented out the onAttachedToWindow() in my Base Activity. I have two Activities inheriting from this

Answer 1

I run into the same question. But after stopping adding

getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
getWindow().setType(WindowManager.LayoutParams.TYPE_KEYGUARD);
requestWindowFeature(Window.FEATURE_NO_TITLE);

before super.onCreate(savedInstanceState); of BaseActivity, it works well. I cut and paste above codes before super.onCreate(savedInstanceState); of descends of BaseActivity.

BTW, I don't think you have to call super.onAttachedToWindow(); inside methods of life circle of Activity. Because onAttachedToWindow(); is called when the view is attached to a window when you overriding a View.
