了解Android中的AudioTrack断言 [英] Understanding AudioTrack Assertion in Android

问题描述

在我的Android应用中，我正在使用AudioTrack API输出从RFCOMM蓝牙连接接收到的音频字节.音频将按预期播放，并且非常清晰.但是，由于AudioTrackShared.cpp中的以下声明，该应用有时会崩溃:

In my Android app, I'm using the AudioTrack API to output audio bytes that I receive from a RFCOMM Bluetooth connection. The audio plays as expected and is very clear. However, the app occasionally crashes due to the following assertion in AudioTrackShared.cpp:

stepCount <= mUnreleased && mUnreleased <= mFrameCount

我不太确定此断言的含义，但是没有人知道可能导致此问题的原因吗?如果需要，我可以提供其他源代码:

I'm not really sure of what this assertion entails, but does anyone have an idea of what could cause this issue? I can provide additional source code if needed:

我对AudioTrack的设置:

My setup for AudioTrack:

int minSize = AudioTrack.getMinBufferSize(8000, AudioFormat.CHANNEL_OUT_MONO, AudioFormat.ENCODING_PCM_8BIT);
mAudioPlayer = new AudioTrack(AudioManager.STREAM_MUSIC, 8000, AudioFormat.CHANNEL_OUT_MONO, AudioFormat.ENCODING_PCM_8BIT, minSize * 4, AudioTrack.MODE_STREAM);

推荐答案

使AudioTrack缓冲区的大小与您从minBufferSize获得的大小相同.那可以解决您的问题.

Make AudioTrack buffer size the same you get from minBufferSize. That could fix your issue.
