我只在摩托罗拉里程碑上遇到这个问题。代码:
// init recorder
recordInstance = new AudioRecord(MediaRecorder.AudioSource.MIC,
8000, AudioFormat.CHANNEL_CONFIGURATION_MONO,
AudioFormat.ENCODING_PCM_16BIT, 8000);
recordInstance.startRecording();
//more code here
recordInstance.stop();
我拥有的错误信息(暂时找不到更多信息,因为我自己没有用于调试的里程碑):
Uncaught handler: thread main exiting due to uncaught exception
java.lang.IllegalStateException: stop() called on an uninitialized AudioRecord.
at android.media.AudioRecord.stop(AudioRecord.java:51 6)
显然我不是唯一一个遇到这个问题的人。我发现了一些非常相似的线程(没有解决方案):
