MediaPlayer Url issue Only on Android 6.0.1

Question

After Calling the below method The app appears to be stuck on the loading screen and stop responding ,I'm performing my tests on a WiFi network so the connection should not be the issue. Testing with Android M 6.0.0 works fine, this only occurs for 6.0.1. Quite annoying, has anybody a hint
