[FIXED] FileNotFoundException using MediaPlayer

Issue

I am trying to solve this problem for hours now and can't find a proper solution: I am trying to Play a media File (Mp3/Ogg) but always get the FileNotFoundException (and I'm sure it's there ;) )

This is what I try:

Check if SD Card is available.

Check if reading/writing permissions are granted.

Load/Play Song.

if(isExternalStorageReadable() && isExternalStorageWritable())
        if (ContextCompat.checkSelfPermission(this, Manifest.permission.READ_EXTERNAL_STORAGE) == PackageManager.PERMISSION_GRANTED) {
            Log.v("Permission","Readingpermission is granted");
        }
        if (ContextCompat.checkSelfPermission(this, Manifest.permission.WRITE_EXTERNAL_STORAGE) == PackageManager.PERMISSION_GRANTED) {
            Log.v("Permission","Writingpermission is granted");
        }
        playSong(getExternalFilesDir(Environment.DIRECTORY_MUSIC).toString() + "/t1.mp3");

That part of the code is working so far.

But as soon as it comes to the playSong(String) :

try {
        MediaPlayer mediaplayer = new MediaPlayer();
        mediaplayer.setDataSource(path);
        mediaplayer.prepare();
        mediaplayer.start();
    } catch (Exception e){
        Log.e("Mediaplayer", e.toString());
    }

The program crashes trying to setDataSource with this Exception:

E/Mediaplayer: java.io.FileNotFoundException: /storage/emulated/0/Android/data/OMSclient.omsgui/files/Music/t1.mp3

What am I missing? I'm clueless.

Alright, I've found the following problem:

If I simply execute

playSong("storage/17E5-1C14/Android/data/OMSclient.omsgui/files/Music/t1.ogg");

It works fine, but if I Use:

playSong("/storage/emulated/0/Android/data/OMSclient.omsgui/files/Music/t1.mp3");

or

playSong("storage/emulated/0/Android/data/OMSclient.omsgui/files/Music/t1.mp3");

It does not.

Why? ...

Solution

Alright. Because getExternalFilesDir did not seem to work, I used the following workaround:

public String getExternalPath(){
    String removableStoragePath = "";
    File fileList[] = new File("/storage/").listFiles();
    for (File file : fileList)
    { if(!file.getAbsolutePath().equalsIgnoreCase(Environment.getExternalStorageDirectory().getAbsolutePath()) && file.isDirectory() && file.canRead())
        removableStoragePath = file.getAbsolutePath(); }
    return removableStoragePath;
}

This code worked fine on every Emulator I tested it. Hope this helps, if somebody had the same problem.
