How to solve QCMediaPlayer mediaplayer NOT present Error?

Question

I'm trying to play .mp3 file from ListView I have tried following but its not working

public static class FirstFragment extends Fragment {
    private MediaPlayer mp;
    View myView;
   private  String[] theNamesOfFiles;
    @Nullable
    @Override
    public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, Bundle savedInstanceState) {
        mp=new MediaPlayer();
        myView= inflater.inflate(R.layout.first_layout,container,false);

        File dir = new File(Environment.getExternalStorageDirectory()+File.separator+"Ringtones");
            File[] filelist = dir.listFiles(new FileFilter() {
                @Override
                public boolean accept(File pathname) {
                    return !pathname.isHidden();
                }
            });
            theNamesOfFiles = new String[filelist.length];
            for (int i = 0; i < theNamesOfFiles.length; i++) {
                theNamesOfFiles[i] = filelist[i].getName();
                int pos = theNamesOfFiles[i].lastIndexOf(".");
                if (pos > 0) {
                    theNamesOfFiles[i] = theNamesOfFiles[i].substring(0, pos);
                }
            }

        ListView listview=(ListView) myView.findViewById(R.id.RecordingList);
        ArrayAdapter<String> listviewAdapter= new ArrayAdapter<String>(
                getActivity(),android.R.layout.simple_list_item_1,theNamesOfFiles
        );
        listview.setAdapter(listviewAdapter);
        listview.setOnItemClickListener(new AdapterView.OnItemClickListener() {
            @Override
            public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
                playSong(position);
            }
        });
        return myView;
    }
    public void playSong(int songIndex)
    {
        //Play Songs
        mp.reset();
        mp=MediaPlayer.create(getActivity().getApplicationContext(),theNamesOfFiles[songIndex]);
        mp.start();
    }
}
}

can anyone tell me how to do this and what i'm missing ?

EDIT I have tried with Uri passing as

 Uri myUri = Uri.parse(theNamesOfFiles[position]);

but the file is not playing and the Error Log is as follows

QCMediaPlayer mediaplayer NOT present

can anyone tell me whats going wrong and what to do?

Try this in playSong method

Uri myUri = Uri.parse("file:///sdcard/mp3/example.mp3");
mp.setAudioStreamType(AudioManager.STREAM_MUSIC);
mp.setDataSource(getApplicationContext(), myUri);
mp.prepare();
mp.start();

On your file list I suppose maybe Environment.getExternalStorageDirectory()+File.separator+"Ringtones" + "/"+ theNamesOfFiles[songIndex]; – C Van Feb 27 '18 at 21:14
the problem is how to pass the path of the clicked item into Uri? – Ravi Patil Feb 27 '18 at 21:15
try passing a route that you know – C Van Feb 27 '18 at 21:18
i have given the path but the file is not playing – Ravi Patil Feb 27 '18 at 21:22

It looks like the log

QCMediaPlayer mediaplayer NOT present

is not related.

Why MediaPlayer throws NOT present error when creating instance of it?

I would add a progressListener to see if it's playing but it's not outputting for some reason.

what is the reason behind that and the link you have given also don't have any answer – Ravi Patil Feb 27 '18 at 22:43
There are a number of reasons why the media player wouldn't play music. I'm wondering if it actually is playing (or thinks it is), but it's just not outputting. I would also add a log statement for your file along the lines of `file.exists()` to make sure that you don't have a path error. – LukeWaggoner Feb 28 '18 at 20:35
