Full screen button does not work in Android webview application.

Hello Guys,

I use videojs player in the webview application.

I created a class named Chrome client. I inherited from the WebChromeClient class.

private class ChromeClient extends WebChromeClient {
        private View mCustomView;
        private WebChromeClient.CustomViewCallback mCustomViewCallback;
        protected FrameLayout mFullscreenContainer;
        private int mOriginalOrientation;
        private int mOriginalSystemUiVisibility;

        ChromeClient() {
        }

        public Bitmap getDefaultVideoPoster() {
            if (mCustomView == null) {
                return null;
            }
            return BitmapFactory.decodeResource(getApplicationContext().getResources(), 2130837573);
        }

        public void onHideCustomView() {
            ((FrameLayout) getWindow().getDecorView()).removeView(this.mCustomView);
            this.mCustomView = null;
            getWindow().getDecorView().setSystemUiVisibility(this.mOriginalSystemUiVisibility);
            setRequestedOrientation(this.mOriginalOrientation);
            this.mCustomViewCallback.onCustomViewHidden();
            this.mCustomViewCallback = null;

            setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);

        }

        public void onShowCustomView(View paramView, WebChromeClient.CustomViewCallback paramCustomViewCallback) {
            if (this.mCustomView != null) {
                onHideCustomView();
                return;
            }


            setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);


            this.mCustomView = paramView;
            this.mOriginalSystemUiVisibility = getWindow().getDecorView().getSystemUiVisibility();
            this.mOriginalOrientation = getRequestedOrientation();
            this.mCustomViewCallback = paramCustomViewCallback;
            ((FrameLayout) getWindow().getDecorView()).addView(this.mCustomView, new FrameLayout.LayoutParams(-1, -1));
            getWindow().getDecorView().setSystemUiVisibility(3846 | View.SYSTEM_UI_FLAG_LAYOUT_STABLE);


            // getWindow().getDecorView().setSystemUiVisibility(3846 | View.SYSTEM_UI_FLAG_LAYOUT_STABLE);
        }
    }

After these operations, the screen works in landscape mode but it does not work as I want.

It goes into strange shapes like in the pictures.Then it goes into horizontal mode. The same happens when I get out of landscape mode. How can I get rid of this situation?
