Android: MediaPlayer setVolume function

For Android MediaPlayer.setVolume, searching the web seems to show 0.0f for no sound, 1.0f for full sound.

Following user100858 solution I just post my exact code that works:

private final static int MAX_VOLUME = 100;
...
...
final float volume = (float) (1 - (Math.log(MAX_VOLUME - soundVolume) / Math.log(MAX_VOLUME)));
mediaPlayer.setVolume(volume, volume);

soundVolume is the volume you would like to set, between 0 and MAX_VOLUME. So between 0 and 100 in this example.

This function is actualy wonderful. Thanks to it you can create a volume scale with any number of steps!

Let's assume you want 50 steps:

int maxVolume = 50;

Then to set setVolume to any value in this range (0-49) you do this:

float log1=(float)(Math.log(maxVolume-currVolume)/Math.log(maxVolume));
yourMediaPlayer.setVolume(log1,log1); //set volume takes two paramater

Nice and easy! And DON'T use AudioManager to set volume! It will cause many side effects such as disabling silent mode, which will make your users mad!
