ExoPlayer reading mp3 file from raw folder

Question

Is there any possibility to set an mp3 file that's located in the app's raw folder to ExoPlayer?

I tried to achieve it with the following code snippet without success unfortunately:

mMediaPath = "android.resource://" + getPackageName() + File.separator + R.raw.ringtone;

Any help is greatly appreciated!

It's possible to load files from the raw folder, the key is to use RawSourceDataSource.

Here's an example(in Kotlin) to create a LoopingMediaSource for an mp3file in the raw directory:

val uri = RawResourceDataSource.buildRawResourceUri(R.raw.mp3file)
val dataSource = RawResourceDataSource(this)
dataSource.open(DataSpec(uri))

val source = ExtractorMediaSource(uri, DataSource.Factory { dataSource }, Mp3Extractor.FACTORY, null, null)

LoopingMediaSource(source)
