Webview broken when change display size in android.

Step when I got this picture.
1. change display size to large
2. back to app (everythings is ok)
3. back to change display size to small
4. back to app again (it's show like below photo)

It's happend with android only because iOS when back to app it will reload app auto.
How can I fixed this issue or how can detect that app will comeback after change display size?

Thanks.
