Check the code from Erel and add this line together with the others in the manifest:

<item name="android:colorBackground">#FF6495ED</item>

Do not expect anyone can give you a congrete answer if you do not upload a small project showing the issue.

How can we know what you did and how?

Away from that
- the Question in #1 is answered.
- you should create A NEW THREAD for any new question/issue you have.
- Also give ENOUGH details for anyone want to help.
- Upload a small project showing the issue.

I´ll not try to guess what could be wrong. Your Manifest helps exactly zero to reproduce the issue.

- the Question in #1 is answered.
- you should create A NEW THREAD for any new question/issue you have.
- Also give ENOUGH details for anyone want to help.
- Upload a small project showing the issue.
