[android-beginners] Re: MediaPlayer Volume Range
Thanks Dave. Although when I tried putting 100 in the setVolume method clickSound.setVolume(100, 100); The volume level in the emulator seems to be louder when compared to 1.0. Any idea? -Marc On Thu, Jan 8, 2009 at 10:39 AM, Dave Sparks davidspa...@android.comwrote: The range is 0 to 1.

[android-beginners] Re: MediaPlayer Volume Range
So should we report that? Any reaction, google employees? -M On Fri, Jan 9, 2009 at 11:48 AM, Dave Sparks davidspa...@android.comwrote: I took a quick look at the code, and it looks like we're not clamping the values. If I'm reading the code correctly - not easy because there are a lot of layers between the Java client and the audio output - it looks like some nasty wrapping effects will occur if you use values higher than 1.0. I would consider that a bug in the code. I suggest sticking to values between 0 and 1. On Jan 8, 3:41 am, Marc Lester Tan mail...@gmail.com wrote: Thanks Dave.
