BUILDING -------- - requirements: Android SDK, Android NDK r6b - If using CDT, correct the project and ndk-sdk locations in .cproject and .project files - On my Win7 x64 box, the first build fails because of a permission error with obj/local/armeabi/libstlport_static.a. Chmod 777:ing the file with cygwin seems to fix the problem.
What steps will reproduce the problem?
1. use .ogg file to play
2.
3.
What is the expected output? What do you see instead?
the sound is noise
What version of the product are you using? On what operating system?
i9300
Please provide any additional information below.
I think the parameter should be config for .ogg file, but I didn't find it,
author, do you know which parameter should I modified for play .ogg file.
Thanks a lot!

What steps will reproduce the problem?
1. Test the current implementation with a medium volume (e.g. 0.5)
2. Test the current implementation with a low volume (e.g. 0.1)
What is the expected output? What do you see instead?
We expect the first test to be about 5 times louder than the second test. If
testing against the native SoundPool we would see this outcome. Instead, the
two tests have nearly the same volume.
A fix for this issue is easily made by replacing the code in
OpenSLSoundPool.cpp between lines 288 and 295 with the following:
// Convert requested volume 0.0 - 1.0 to millibels
if (volume <= 0.0f) {
volume = 0.001f; // Can't actually take the log of 0 so bump it up a bit
} else if (volume > 1.0f) {
volume = 1.0f;
}
SLmillibel newVolume = (SLmillibel) (1000.0f * log(volume));
I removed the three unused #defines in OpenSLSoundPool.h but maybe you'd rather
use the NDKSP_MIN/MAX_VOLUME #defines with the range checking code? This
requires the addition of #include <math.h> in OpenSLSoundPool.cpp but gives
much better volume scaling than the current implementation; almost exactly the
same as the native SoundPool does.
I guess I should also mention this lets you take out the minVolume and
maxVolume private variables of OpenSLSoundPool along with the code that
initializes them since they are also no longer used.
