Failing to remove callback when user disconnects from WiFi

[ReyhanJB]

What steps will reproduce the problem?
In the setting, enable wifi only mode. Create a playlist with several musics. Start the playlist. When the first song is playing, disable WiFi.

What is the expected output? What do you see instead?
Jamendo keeps running in the background (It does not play any song, but keeps running in background) and does not remove the callback that is responsible to track the music play progress.

Please provide any additional information below
In the "PlayerEngineImpl.java" class, "mHandler" is responsible to run "mUpdateTimeTask" periodically (every one second). It seems that mHandler will be remove when the player is not playing. However, it seems that disconnecting from internet does not impact the playing status of the playlist. To ensure the callback is still executed in background, I added a log file in the method "run()" of "mUpdateTimeTask". After reproducing the issue, I can see that the log appears in the logcat every second.
