`RuntimeException` on stop about audio_recorder

To make matters worse, you cannot stop the recording after is error was thrown. Also, await AudioRecorder.isRecording stays returning true.

If you try to call AudioRecorder.stop() again:

[huangruiLearn]

may cause by stop() is called immediately after start()... i tried `` try {
mRecorder.stop();
mRecorder.reset();
mRecorder.release();
mRecorder = null;
}catch (RuntimeException e){

}` ``
Is there a better way?
