[JCKodel]

Describe the bug
The cover appears, the loading spins and, when the video starts, there is a crash:

Fatal Exception: java.lang.NullPointerException: Attempt to invoke virtual method 'int android.graphics.Bitmap.getWidth()' on a null object reference

This behavior don't affect iOS.

To Reproduce
Steps to reproduce the behavior:
Unknown (I've implemented the player for iOS and then when I tested on Android, this crash terminated my app).

Expected behavior
To work.

Technical Details:

• Device: [e.g. iPhone6] MotoG 1st Edition (2013)
• OS: [e.g. iOS8.1] Android
• Version [e.g. 22] 5.1

Additional context
There is a Google AdMob banner at the bottom of the page (so my app is built with a container with a bottom padding to accomodate the banner, since the ad plugin only shows banners on top or bottom)
