在Media Player Android上播放MediaStore的音频

Question

Is there a way to play audio obtained from MediaStore through the use of the MediaPLayer, Or am I going in the completely wrong direction? I've looked and MediaStore.Audio so far but nothing is really helping me. I just need to know if I'm on the right track

Answer 1

First, I assume you have basic knowledge of querying a ContentProvider and working with Cursors. If you dont, I suggest you research it here

Once you have a basic knowledge of how to use a ContentProvider, query the URI MediaStore.Audio.Media.EXTERNAL_CONTENT_URI for the column Audio.Media.DATA , along with any other fields you need.

Let's say you put the returned cursor in yourCursor

String path = yourCursor.getString(getColumnIndex(Audio.Media.DATA));

MediaPlayer mp = new MediaPlayer();
mp.setDataSource(path);
mp.prepare();
mp.start();

That's a very basic implementation. Get comfy with the android docs if you need to get fancy with it.

Answer 2

Have a look at the bundled music application source:

1. List music using content providers
2. Use MediaPlayer in order to play the file you will get from the cursor

You also have examples on the android developer website: http://developer.android.com/guide/topics/media/index.html
