Android VideoView “Video cannot be played” works in Gallery

Question

I receive an error when trying to play a large m4v file in my Android application. "Sorry, this video cannot be played" The VideoView's onError handler gets called like: onError(MediaPlayer mp, int what, int extra)

With "what" being 1 and "extra" being -2147483648

The exact same video plays without issues in the Gallery application.

Answer 1

have you set the permission to read the internal storage???

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"></uses-permission>
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"></uses-permission>

do this and it should work

Answer 2
