android - How to play file from external storage in exoplayer?

Question

From assets all working fine! But from external storage no.

This is my exoplayer instance:

// ExoPlayer
        val renderesFactory = DefaultRenderersFactory(
            this,
            DefaultRenderersFactory.EXTENSION_RENDERER_MODE_OFF
        )
        val trackSelector = DefaultTrackSelector()
        exoPlayer = ExoPlayerFactory.newSimpleInstance(
            this@PlayerService,
            renderesFactory,
            trackSelector
        )
        exoPlayer!!.addListener(exoPlayerListener)

Here I'm trying to build a path:

val dirPath = applicationContext.getExternalFilesDir(audio.uri)!!.absolutePath
val filePath = "$dirPath/001.mp3"
val audioFile = File(filePath)
val uri = Uri.fromFile(audioFile)
prepareToPlay(uri)

audio.uri --> "Downloads/audio_reading/"
And this is prepareToPlay() method:

private fun prepareToPlay(uri: Uri) {
            if (uri != currentUri) {
                currentUri = uri
                val userAgent = Util.getUserAgent(this@PlayerService, "ExoPlayer")
                val mediaSource = ExtractorMediaSource(
                    uri,
                    DefaultDataSourceFactory(this@PlayerService, userAgent),
                    DefaultExtractorsFactory(), null, null
                )
                exoPlayer!!.prepare(mediaSource)
            }
        }

When I start app and click "play" I'm getting that error:

E/ExoPlayerImplInternal: Source error.

Answer 1

As mentioned in the comments, the error is indicting that the system is seeing the path you are trying to open not as a file but as a directory.

open failed: EISDIR (Is a directory)

You code to open the file looks good so one common reason for an error like this is that the code that actually created or stored the file created a directory rather than a file - e.g. if the following is called:

yourFilePath.mkdirs()

This will actually create a directory called 'yourFilePath' rather than create a directory for a file called 'yourFilePath'.
