Current bug behaviour

error throw on configAndPrepare in WrappedPlayer

audioplayers/packages/audioplayers_android/android/src/main/kotlin/xyz/luan/audioplayers/player/WrappedPlayer.kt

Lines 306 to 307 in 414d94d

	private fun Player.configAndPrepare() {
	setRate(rate)

Expected behaviour

Error should throw when the user use the setRate function in api < 23.

Steps to reproduce

1. Install to example app in android device api < 23
2. change mode to play instead of setSource
3. Press Asset 1 - laser.wav
4. See a crash

More information

we can change to configAndPrepare to

    private fun Player.configAndPrepare() {
        try {
            setRate(rate)
        }catch (e: Exception){ }
        setVolume(volume)
        setLooping(isLooping)
        prepare()
    }

or check the sdk version in the Player.configAndPrepare before calling setRate

With the "try catch", I can play sound on android 5.1.1

@aideric I think that setting Player to Low Latency mode will resolve this issue for you. It doesn't seem that the MediaPlayer supports variable playback rates.

player.setPlayerMode(PlayerMode.LowLatency)

@aideric are you interested in working on a fix? We are currently on our capacities 😅
