Media Player state error when calling PlaylistManager.play() with a seek position greater than 0 about playlistcore

[brianwernick]

I wonder if this is what #34 was trying to describe.

Anyways, reproduction steps:
1. Play the 2nd-4th audio item in the demo
2. Back out of the player activity
3. Select the 1st item

• What I was seeing was a bug in the demo. @AngelJedi would you upload your reproduction steps

Expected Result:

The 1st item plays correctly

Actual Result:

The playlist resumes where it was previously playing

It looks like I was in the wrong area for what was happening and I saw something out of place, but it wasn't the cause.

The real culprit seems to be line #1227 of PlaylistServiceCore which calls performPause() in an invalid state on the media player if I pass a seekPosition other than 0 into the play() method of my playlist manager.

After calling that method the media player outputs these two lines into my log:

E/MediaPlayer: pause called in state 8, mPlayer(0x7f0758dac0)
E/MediaPlayer: error (-38, 0)

Then the onError method of the MediaListener is called, which tries to retry playback a number of times, each time causing a state error on the media player, and then eventually the next item is queued up for playback because of the error.
