According to the SDK, the parameters are:
Using java Syntax Highlighting
- public final int play (int soundID, float leftVolume, float rightVolume, int priority, int loop, float rate)
Parsed in 0.034 seconds, using GeSHi 1.0.8.4
However, the left/right channels seem to be reversed for me, when I call it like this:
Using java Syntax Highlighting
- play(idx, 0f, 1f, 1, 0, 1f)
Parsed in 0.030 seconds, using GeSHi 1.0.8.4
the sound plays on the left and if I swap the l/r parameter it plays on the right. I'm not sure if this a bug in the documentation, a bug in the SDK, or a bug in the emulator. Unfortunately I've lost my headphone adapter for my G1 so I can't test it on a real device.
If anybody has any further info it would be greatly appreciated!
