具体表现:
调用MediaRecorder的start()与stop()间隔不能小于1秒(有时候大于1秒也崩),否则必崩。
错误信息:
java.lang.RuntimeException: stop failed.
at android.media.MediaRecorder.stop(Native Method)
解决办法:
在stop以前调用setOnErrorListener(null);就行了!

mMediaRecorder = new MediaRecorder();
mMediaRecorder.setOnErrorListener(this);
} else {
mMediaRecorder.reset();

结尾吐槽:
1、这个bug太2了!!
2、Instagram你是怎么发现的?!
后续补充:
1、如果单独设置不管用,请参考代码部分的完整代码设置。
