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！

相关代码：

/** 开始录制 */ @Override public MediaPart startRecord() { if (mMediaObject != null && mSurfaceHolder != null && !mRecording) { MediaPart result = mMediaObject.buildMediaPart(mCameraId, ".mp4"); try { if (mMediaRecorder == null) { mMediaRecorder = new MediaRecorder(); mMediaRecorder.setOnErrorListener(this); } else { mMediaRecorder.reset(); } // Step 1: Unlock and set camera to MediaRecorder camera.unlock(); mMediaRecorder.setCamera(camera); mMediaRecorder.setPreviewDisplay(mSurfaceHolder.getSurface()); // Step 2: Set sources mMediaRecorder.setVideoSource(MediaRecorder.VideoSource.CAMERA);//before setOutputFormat() mMediaRecorder.setAudioSource(MediaRecorder.AudioSource.MIC);//before setOutputFormat() mMediaRecorder.setOutputFormat(MediaRecorder.OutputFormat.MPEG_4); //设置视频输出的格式和编码 CamcorderProfile mProfile = CamcorderProfile.get(CamcorderProfile.QUALITY_480P); // mMediaRecorder.setProfile(mProfile); mMediaRecorder.setVideoSize(640, 480);//after setVideoSource(),after setOutFormat() mMediaRecorder.setAudioEncodingBitRate(44100); if (mProfile.videoBitRate > 2 * 1024 * 1024) mMediaRecorder.setVideoEncodingBitRate(2 * 1024 * 1024); else mMediaRecorder.setVideoEncodingBitRate(mProfile.videoBitRate); mMediaRecorder.setVideoFrameRate(mProfile.videoFrameRate);//after setVideoSource(),after setOutFormat() mMediaRecorder.setAudioEncoder(MediaRecorder.AudioEncoder.AAC);//after setOutputFormat() mMediaRecorder.setVideoEncoder(MediaRecorder.VideoEncoder.H264);//after setOutputFormat() //mMediaRecorder.setVideoEncodingBitRate(800); // Step 4: Set output file mMediaRecorder.setOutputFile(result.mediaPath); // Step 5: Set the preview output // mMediaRecorder.setOrientationHint(90);//加了HTC的手机会有问题 Log.e("Yixia", "OutputFile:" + result.mediaPath); mMediaRecorder.prepare(); mMediaRecorder.start(); mRecording = true; return result; } catch (IllegalStateException e) { e.printStackTrace(); Log.e("Yixia", "startRecord", e); } catch (IOException e) { e.printStackTrace(); Log.e("Yixia", "startRecord", e); } catch (Exception e) { e.printStackTrace(); Log.e("Yixia", "startRecord", e); } } return null; } /** 停止录制 */ @Override public void stopRecord() { long endTime = System.currentTimeMillis(); if (mMediaRecorder != null) { //设置后不会崩 mMediaRecorder.setOnErrorListener(null); mMediaRecorder.setPreviewDisplay(null); try { mMediaRecorder.stop(); } catch (IllegalStateException e) { Log.w("Yixia", "stopRecord", e); } catch (RuntimeException e) { Log.w("Yixia", "stopRecord", e); } catch (Exception e) { Log.w("Yixia", "stopRecord", e); } } if (camera != null) { try { camera.lock(); } catch (RuntimeException e) { Log.e("Yixia", "stopRecord", e); } } mRecording = false; } /** 释放资源 */ @Override public void release() { super.release(); if (mMediaRecorder != null) { mMediaRecorder.setOnErrorListener(null); try { mMediaRecorder.release(); } catch (IllegalStateException e) { Log.w("Yixia", "stopRecord", e); } catch (Exception e) { Log.w("Yixia", "stopRecord", e); } } mMediaRecorder = null; } @Override public void onError(MediaRecorder mr, int what, int extra) { try { if (mr != null) mr.reset(); } catch (IllegalStateException e) { Log.w("Yixia", "stopRecord", e); } catch (Exception e) { Log.w("Yixia", "stopRecord", e); } if (mOnErrorListener != null) mOnErrorListener.onVideoError(what, extra); }
