Android MediaPlayer - error (1, -4) when playing a song

Question

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

I have a Spinner filled with the track names stored on the 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 get the following errors:

Does anyone know about this? Thanks in advance:)

Answer 1

Dude you put mP.prepare(); on the wrong line, you need to call it after the function mP.setDataSource(context, uri); and to mp.start();

Also, do not try to make multiple instances of MediaPlayer . Do this and use the reset () function each time before starting.

See this link for more details.

Answer 2

Do you have this permission in AndroidManifest.xml?

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

Answer 3

Incrorect is the name of the file or the path to the file that is set to .setDataSource(fileName) .

Or an invalid call to .prepare() (MUST .setDataSource() before .prepare() ). See @TheLittleNaruto answer.
