Getting the Title of an MP3 throws "java.lang.IllegalArgumentException"

Why does this code throw a IllegalArgumentException? I want to show the Title of an MP3-File which is located at the "raw" folder

mediaPlayer = MediaPlayer.create(getActivity(), R.raw.willy_william_ego);
            MediaMetadataRetriever mmr = new MediaMetadataRetriever();
            Uri uri = (Uri) Uri.fromFile(new File("android.resource://com.hthl.kellergassen_app/raw/willy_william_ego"));
            mmr.setDataSource(getActivity(), uri);
            String title = mmr.extractMetadata(MediaMetadataRetriever.METADATA_KEY_TITLE);

Assuming you're getting the issue in setDataSource, it'll be because the URI you're passing in isn't valid for some reason - most likely because the file couldn't be found. Are you sure it's present with that name and doesn't have a file extension?

From the Javadoc...

void setDataSource (Context context, Uri uri)

Sets the data source as a content Uri. Call this method before the rest of the methods in this class. This method may be time-consuming.

Parameters context Context: the Context to use when resolving the Uri uri Uri: the Content URI of the data you want to play

Throws IllegalArgumentException if the Uri is invalid SecurityException if the Uri cannot be used due to lack of permission.

UPDATE - Having looked at your code, it seems you're using the hard-coded String com.hthl.kellergassen_app as the package name, but that's not right. According to the stacktrace it's com.htlhl.kellergassen_app - note the extra "l" in "htlhl" (this is in the String you use to create the URI).
