String path = Environment.getExternalStorageDirectory().toString()+"/Music/";
    File directory = new File(path);
    File[] mSongsList = directory.listFiles();

    Uri mUri= Uri.fromFile(mSongsList[0]);
    Log.v("MainActivity",mUri.toString());
    mMediaPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);
    mMediaPlayer.setDataSource(this, mUri);

You can play the song from your device by the following codes, but I don't know how to play next songs and previous songs , if you have any idea , pls share me.

fun getURI(){
    val path: String =
        Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_MUSIC).getAbsolutePath()
    val directory = File(path)

    try {
         mSongsList= directory.listFiles()
        val mUri = Uri.fromFile((mSongsList as Array<File>?)!![0])
        Log.v("MainActivity", mUri.toString())

        mp!!.reset()
        mp!!.setAudioStreamType(AudioManager.STREAM_MUSIC)
        mp!!.setDataSource(this, mUri)
        mp!!.prepare()
        mp!!.start()
    } catch (e: IOException) {
        e.printStackTrace()
    }
}

Place music files(s) under res/raw or any other folder under SD card. We are going to refer the audio file based on the Uri.

Create MediaPlayer object:

MediaPlayer mPlayer = new MediaPlayer();

Locate the audio file:

Uri myUri1 = Uri.parse("file:///sdcard/Songs/ARR Hits/hosannatamil.mp3");

Set the audio stream type of the media player:

mPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);

Set the data source as a content Uri:

try {
    mPlayer.setDataSource(getApplicationContext(), myUri1);
} catch (IllegalArgumentException e) {
    Toast.makeText(getApplicationContext(), "You might not set the URI 
    correctly!", Toast.LENGTH_LONG).show();
} catch (SecurityException e) {
    Toast.makeText(getApplicationContext(), "You might not set the URI 
    correctly!", Toast.LENGTH_LONG).show();
} catch (IllegalStateException e) {
    Toast.makeText(getApplicationContext(), "You might not set the URI 
    correctly!", Toast.LENGTH_LONG).show();
} catch (IOException e) {
    e.printStackTrace();
}

Prepare the player for playback, synchronously:

try {
    mPlayer.prepare();
} catch (IllegalStateException e) {
    Toast.makeText(getApplicationContext(), "You might not set the URI 
    correctly!", Toast.LENGTH_LONG).show();
} catch (IOException e) {
    Toast.makeText(getApplicationContext(), "You might not set the URI 
    correctly!", Toast.LENGTH_LONG).show();
}

Start the player:

mPlayer.start();

First of all make sure you have read permissions in your manifest file.

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

If you are using the android version Marshmallow or above you need to ask the user for Runtime Permissions.

This is a good article to request runtime permissions.

For now you can go to the app info page and give the permissions manually. It will start working.

Replace Your Code Like below:

Note: Make Sure That You Have Some Music In MusicDirectory. 

    String path = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_MUSIC).getAbsolutePath();
                File directory = new File(path);
try{
 File[] mSongsList = directory.listFiles();

                Uri mUri= Uri.fromFile(mSongsList[0]);
                Log.v("MainActivity",mUri.toString());
                mMediaPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);
                mMediaPlayer.setDataSource(this, mUri);
                mMediaPlayer.prepare();
                mMediaPlayer.start();
}catch(IOException exception){
    e.printStacktrace();
}

Keep your code inside the try-catch block.

try{
// your code
}catch(IOException exception){

}

This is because you are trying to get the music file. If its not present then it will throw IOException, so you must handle this.
