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

Remove

this.getWindow().setType(WindowManager.LayoutParams.TYPE_KEYGUARD_DIALOG|WindowManager.LayoutParams.FLAG_FULLSCREEN);

From your onAttachedToWindow(), like this:

 @Override
     public void onAttachedToWindow() {
        //this.getWindow().setType(WindowManager.LayoutParams.TYPE_KEYGUARD_DIALOG|WindowManager.LayoutParams.FLAG_FULLSCREEN);

          super.onAttachedToWindow();
     }

Answer 2

Sorry for late reply. You should add:

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

in onCreate method if you are using api level 15 or above. It works for me.

Answer 3

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.

Answer 4

I also had this problem, but I solved it by removing the Window, changing the params and then adding the window again. This was good enough for me.

WindowManager.removeView(View); params = params2; //changed the params to something else WindowManager.updateViewLayout(View, params); WindowManager.addView(View, params);

Answer 5

Try to use this for window :

requestWindowFeature(Window.FEATURE_NO_TITLE);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
                     WindowManager.LayoutParams.FLAG_FULLSCREEN);
setContentView(R.layout.activity_adjectives);
