Set volume to max in Android

Question

In my app, I am trying to set the volume when playing an audio clip to the maximum level but it doesn't appear to have any affect. I have to manually adjust the volume to the maximum level. Here's my code:

MediaPlayer mp = new MediaPlayer();
mp.setVolume(1, 1);

AudioManager

int origionalVolume = mAudioManager.getStreamVolume(AudioManager.STREAM_MUSIC);
mAudioManager.setStreamVolume(AudioManager.STREAM_MUSIC, mAudioManager.getStreamMaxVolume(AudioManager.STREAM_MUSIC), 0);

wrong. It changes the user setting – Linga Apr 26 '13 at 06:00
So what's the purpose of setVolume for MediaPlayer? – Johann Apr 26 '13 at 06:02
Yes this works. Not sure what ling means by changing the user setting. Does this mean that using this code will change the volume globally on the device for all audio or just the current audio being streamed? – Johann Apr 26 '13 at 06:11
@AndroidDev : I think ling.s new in android. you can use this code for max volume – Nirav Ranpara Apr 26 '13 at 06:12
@AndroidDev it will change volume for all music volume globally – Poovizhirajan N Apr 26 '13 at 06:34
oh come on you can obviously use the `orignalVolume` to set it back to the user desired volume – Muhammad Babar May 27 '13 at 10:19
if this code doesn't work, don't forget the MODIFY_AUDIO_SETTINGS permission : – Oubaida AlQuraan Oct 28 '16 at 11:35

Use This

it s for total volume

AudioManager mgr = (AudioManager) appContext.getSystemService(Context.AUDIO_SERVICE);
        int valuess = 9;//range(0-15)
mgr.setStreamVolume(AudioManager.STREAM_MUSIC, valuess, 0);

it is for left right while current song is playing...

AudioTrack m = (AudioTrack) appContext.getSystemService(Context.AUDIO_SERVICE);
m.setStereoVolume(leftVolume, rightVolume);

it works for me.

i get an java.lang.ClassCastException: android.media.AudioManager cannot be cast to android.media.AudioTrack when i try your solution for the current song. any idea why? – SjoerdvGestel Oct 01 '13 at 14:55
check imports you imported wrong audio manager.... – Poovizhirajan N Oct 03 '13 at 04:01
You have twice the same getSystemService(Context.AUDIO_SERVICE) first casted as AudioManager (correctly) and second casted as AudioTrack (incorrectly) I assume second service should be something else than AUDIO_SERVICE (or even other method) – Lukasz 'Severiaan' Grela Oct 27 '14 at 23:38
while playing the song we need to use AudioTrack – Poovizhirajan N Oct 28 '14 at 04:38

Using AudioManager you can control the volume of media player.

AudioManager audioManager = (AudioManager)getSystemService(Context.AUDIO_SERVICE);
audioManager.setStreamVolume(AudioManager.STREAM_MUSIC, 20, 0);

also from MediaPlayer

public void  setVolume  (float leftVolume, float rightVolume)

for example you can use this method as,

int maxVolume = 100;
float log1=(float)(Math.log(maxVolume-currVolume)/Math.log(maxVolume));
mp.setVolume(1-log1);
