Show your blocks. Someone could find a solution maybe then.

its my block on screen 1 , screen 2 ( BCB ) still working on the blocks .

there is only webviewer as component

How can you know that you have a problem if you do not have the relevant blocks yet??
First make your app, then describe precisely what is going wrong, for example by showing the relevant blocks, otherwise you are wasting our time.
Cheers, Ghica.

To be able to play Youtube videos in the webviewer, you have to edit the manifest and add android:targetSdkVersion="14" or higher. Thank you Boban!

It does not look like you have used the forums yet, as a search using the search box above would have returned several threads about this topic.
