Questions:

I am trying to play an mp3 audio file from sd card, using the path and the filename of the audio file to get its Uri.

I have a Spinner populated with the tracks names stored in sd card.
When an item is selected, the following code will be executed:

final Uri uri = MediaStore.Audio.Media.EXTERNAL_CONTENT_URI;
OnItemSelectedListener listener = new OnItemSelectedListener(){
        @Override
        public void onItemSelected(AdapterView<?> parentView, View selectedItemView, int position, long id) {
            TextView tv = (TextView) selectedItemView;

            File file = new File(uri.getPath() + "/" + tv.getText().toString());
            Log.i(TAG, "-------------  PATH : " + file.getAbsolutePath());
            Uri uri = Uri.fromFile(file);
            MediaPlayer mP = new MediaPlayer();
            try {
                mP.setDataSource(context, uri);

                mP.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
                    @Override
                    public void onPrepared(MediaPlayer mp) {
                        // TODO Auto-generated method stub
                        mp.start();

                    }
                });

            } catch (IllegalArgumentException e) {
                  e.printStackTrace();
            } catch (IllegalStateException e) {
              e.printStackTrace();
            } catch (IOException e) {
              e.printStackTrace();
            }
            try {
                mP.prepare();
            } catch (IllegalStateException e) {
              e.printStackTrace();
            } catch (IOException e) {
             e.printStackTrace();
            }

        }
    };

I am getting the following errors:

Does anyone have any idea about it?
Thanks in advance 🙂

How to&Answers:

Dude you have placed mP.prepare(); at wrong line
you need to call it after mP.setDataSource(context, uri); function
and before mp.start();

Also not try to make several instances of MediaPlayer. Make one and use reset() function everytime before start.

Please see this link for more help.

Answer:

Do you have this permission in AndroidManifest.xml?

<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />

Answer:

Incrorect file name or path to file which set in.setDataSource(fileName).

Or wrong call .prepare() (MUST CALL .setDataSource() before .prepare()) .See answer @TheLittleNaruto.
