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 class, BaseActivity. One runs, and one does not. What could be the difference? My target SDK is 19; changing it to 12 makes no difference. Here is my onCreate for BaseActivity:

    @Override
    protected void onCreate(Bundle savedInstanceState) {
    getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
    this.getWindow().setType(WindowManager.LayoutParams.TYPE_KEYGUARD);
    requestWindowFeature(Window.FEATURE_NO_TITLE);
    super.onAttachedToWindow();
    super.onCreate(savedInstanceState);

    ....
    }

When navigating to the second activity, stepping through the code, it makes it through onCreate(), onResume(), then crashes.

What could be the problem?

EDIT: if I change to target API 12 and put all of the changes in from onCreate into onAttachedToWindow, I can get this exception to go away, but I'd like the target SDK to be 19.

My new onCreate():

@Override
protected void onCreate(Bundle savedInstanceState) {

    requestWindowFeature(Window.FEATURE_NO_TITLE);
    super.onCreate(savedInstanceState);
...
}

My new onAttachedToWindow():

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

This only works with target API 12.

Answer Min target must be less than 14 when WindowManager.LayoutParams.TYPE_KEYGUARD used

try this for API 19 : https://developer.android.com/training/system-ui/immersive.html — Fouad Wahabi, Jun 30 '15 at 20:36
Do not call `super.onAttachedToWindow()` anywhere other than from inside your override of `onAttachedToWindow()`, if you have one. While I cannot speak to `TYPE_KEYGUARD`, the rest of that code should be after `super.onCreate()`, but before any `setContentView()` call. Beyond that, see if you have anything interesting in your manifest that might explain the difference between your two activities. — CommonsWare, Jul 01 '15 at 16:21
The only thing that's different between the two activities is: android:clearTaskOnLaunch="true" — Kristy Welsh, Jul 01 '15 at 16:27
someone mentioned allready taht the super.onCretae() should be called at the beginning of onCreate(), so try this. And also you dont need to call the onAttachedWindow() method! — Ilja KO, Jul 06 '15 at 06:33

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);

This will probably be the answer that gets awarded the bounty, but this answer DID NOT WORK. – Kristy Welsh Jul 07 '15 at 20:30

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.

getWindow().setType(WindowManager.LayoutParams.TYPE_KEYGUARD); TYPE_KEYGUARD is deprecated. — Kristy Welsh, Dec 15 '15 at 22:01

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);

This was the only thing that worked for me in an AccessibilityService overlay. But the `updateViewLayout` isn't necessary since the view has already been removed from the window and will be re-added in the next line. – Brad Feb 14 '22 at 15:59

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();
     }

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.
