IOException when playing .mp4 with android mediaplayer

Question

I am trying to play a .mp4 file in MediaPlayer but it always throws an IOException at mediaplayer.prepare():

private MediaPlayer mediaPlayer;

@Override

        mediaPlayer = new MediaPlayer();
        mediaPlayer.setScreenOnWhilePlaying(true);
        mediaPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);
        mediaPlayer.setOnPreparedListener(new MediaPlayer.OnPreparedListener()
        {
            @Override
            public void onPrepared(MediaPlayer mp)
            {
                if (mediaPlayer != null)
                    mediaPlayer.start();
            }
        });

        mediaPlayer.reset();
        try
        {
            FileInputStream fileInputStream = new FileInputStream(file);
            mediaPlayer.setDataSource(getApplicationContext(), Uri.parse(file));
            fileInputStream.close();
            mediaPlayer.prepare();
        }
        catch (IOException e)
        {
            e.printStackTrace();
        }
    }
}

}

Can somebody help me out here?

Does the file exist at that location? You can check with file.exists(); — Sybregunne, Sep 21 '15 at 12:31

Try using

String file= Environment.getExternalStorageDirectory().toString()+"/Download/media/_29187_v.1_Light_Bulb_16HD_25fps.mp4";

File f = new File(file);

And also add

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

to your Manifest file

I have now a solution for my problem.
I don't really know why with MediaPlayer it is not possible to play this video in my test application but with VideoView it is.

Here is my code with Videoview:

public class VideoViewActivity extends Activity
{
VideoView videoView;

@Override
protected void onCreate(Bundle savedInstanceState)
{
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_video_view);

    videoView = (VideoView) findViewById(R.id.videoView);
}

@Override
protected void onResume()
{
    super.onResume();

    String file = Environment.getExternalStorageDirectory().toString() + "/Download/media/Light_Bulb.mp4";

    File f = new File(file);
    if (f.exists())
    {
        videoView.setMediaController(null);
        videoView.setOnPreparedListener(new MediaPlayer.OnPreparedListener()
        {
            @Override
            public void onPrepared(MediaPlayer mp)
            {
                videoView.start();
            }
        });
        videoView.setVideoURI(Uri.parse(file));
    }

    findViewById(R.id.closeVideoView).setOnClickListener(new View.OnClickListener()
    {
        @Override
        public void onClick(View v)
        {
            System.exit(0);
        }
    });
}

@Override
protected void onPause()
{
    super.onPause();
    if (videoView != null)
        videoView.stopPlayback();
}
