Unable to start activity, virtual method?


This question already has an answer here:


mpAudio =   MediaPlayer.create(this, R.raw.youngagain)

MediaPlayer.create() return a MediaPlayer object, or null if creation failed.

MediaPlayer.create() failed and mpAudio = null .

So when you mpAudio.setLoop, you get nullpointer error.
