Android Media Player

For this app, you'll build a simple media player app which will allow a user to retrieve audio files and play them.

Requirements

Add a button to post an intent to request a file.

You can use .setType("audio/*") to specify which type of file to return
Use MediaPlayer or VideoView to play the files as required
Allow for basic controls:
- Play/Pause
- Display progress in track with a SeekBar
- Allow user to use the SeekBar to move to different points in the track
To call mediaPlayer.release() when you activity is stopped and create a new one in onStart

There are a few additional features which you can include in order to improve your app

Allow users to select either audio or video files and play each one accordingly

Use setType("video/*") to retreive a video
Save each track persistently with the last played position to allow the user to pick up where they left off
When tracks are added, add them to a list and allow the user to select previous tracks from that list
Instead of an intent to retrieve the images, use that intent to request a directory using setType("file/*") then step through that directory to add all media files inside of it to your list.
