Android mediarecorder stop failed

Solution
If the recorder is not in a recording state, then the stop could fail.

Problem
I've faced a very strange behavior: sometimes my mediarecorder crashes with an error "Stop failed" and sometimes it works fine. Is there my fault or it is a bug of the system? I cant't get what is wrong. ``` private void stopRecording(){ ticker.cancel(); ticker.purge(); recorder.stop(); startBtn.setText("Start"); recordInProcess = false; markList = locWriteTask.getMarkArray(); mCamera.lock(); recorder.release(); } private void startRecording(){ startBtn.setText("Stop"); recordInProcess = true; recorder = new MediaRecorder(); mCamera.unlock(); recorder.setCamera(mCamera); recorder.setPreviewDisplay(mSurfaceHolder.getSurface()); recorder.setAudioSource(MediaRecorder.AudioSource.MIC); recorder.setVideoSource(MediaRecorder.VideoSource.CAMERA); recorder.setOutputFormat(MediaRecorder.OutputFormat.THREE_GPP); recorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB); recorder.setVideoEncoder(MediaRecorder.VideoEncoder.MPEG_4_SP); recorder.setMaxDuration((int) 10000000); recorder.setVideoSize(320, 240); recorder.setVideoFrameRate(15); recorder.setOutputFile(FULL_PATH_TO_LOCAL_FILE + counter + MP4); try{ recorder.prepare(); } catch (Exception e){ finish(); } lm.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0, 0, ll); ticker = new Timer(); locWriteTask = new WriteTimeLocationTimerTask(ll); ticker.schedule(locWriteTask, 0, DELAY); recorder.start(); } ```
