Android : How to set MediaPlayer volume programmatically?

Question

How to set the mediaplayer volume programmatically. I use it for alarm notification. Any help is highly appreciated and thanks in advance.

Answer 1

You can do the below using Kotlin, this code will check if the media volume is more than 20% of the maximum volume of the device, and will reduce it to be 20% only.

    val audio = this.getSystemService(Context.AUDIO_SERVICE) as AudioManager
    val level = audio.getStreamVolume(AudioManager.STREAM_MUSIC)

    val maxVolume = audio.getStreamMaxVolume(AudioManager.STREAM_MUSIC)
    val percent = 0.2f
    val twintyVolume = (maxVolume * percent).toInt()

    if ( level > twintyVolume) {
        Toast.makeText(this,"audio level is $level", Toast.LENGTH_LONG).show()
        audio.setStreamVolume(AudioManager.STREAM_MUSIC,twintyVolume,0)
    }
