问题 I know the question can be regarded as "politically incorrect", but I'm designing an app which "by design" must get the attention of people within the maximum possible distance range, otherwise it will not be used... :-) I'm currently using SoundManager class, and this is the code which plays my ogg clip: public void playSound(int index) { int streamVolume = mAudioManager.getStreamVolume(AudioManager.STREAM_MUSIC); mSoundPool.play(mSoundPoolMap.get(index), streamVolume, streamVolume, 0, 0, 1

Thanks! 回答1: There does not seem to be a quick and easy way to adjust the volume.. If you have
