从内部存储android播放.mp3

Question

I know there are several questions about this, sadly none of them helps me. (or I am too stupid to apply the answer to my problem).

On my virtual phone I created the folder "Musik" inside this folder a "King.mp3" is located.

I am not able to play this mp3 via media player.

This is the crucial part of my code:

MediaPlayer mp;
mp = MediaPlayer.create(this, Uri.parse(Environment.getExternalStorageDirectory().getPath()+
                "/Musik/King.mp3"));
mp.start();

I already tried it with:

mp.setDataSource(Environment.getExternalStorageDirectory().getPath()+
                    "/Musik/King.mp3");
mp.prepare();
mp.start();

but it is still not working.

(I know there is a lot of useless stuff in the code, I just wanted to show the mp3 path (on the right).

I tried pasting the mp3 directly into the "sdcard".

i dont even care if the path would be hard coded like "/storage/sdcard/Musik" (already tried, its not working. not even with mnt/sdcard/Musik

Answer 1

Did you verify what path "Environment.getExternalStorageDirectory()" is? Maybe it is not what you expect it to be. This path doesn't necessarily always point to the external sd card location.

You're probably using the wrong path o no permission. I recommend you to check the path and check if exits with File.exists() method .
