You're probably experiencing this NPE because your app is probably re-using MediaSource instances. As per the developer guide, you should not do this, although we will be removing this restriction in future versions (probably from 2.8.0).

Alternatively, it's possible that you're app is hitting #3796, which was fixed in 2.7.0.
