Android多线程错误

Question

当我调用finishRecord（）调试器返回错误时：

                    05-09 19:26:58.491 17576-17576/? E/Zygote: accessInfo : 0

我的finishRecord方法是：

  public void finishRecord() {
            mr.stopRecording();
            try {

                int recorderStateLocal = recorderState;
                if (recorderStateLocal != RECORDER_STATE_IDLE) {
                    synchronized (recorderStateMonitor) {
                        recorderStateLocal = recorderState;
                        if (recorderStateLocal == RECORDER_STATE_STARTING
                                || recorderStateLocal == RECORDER_STATE_BUSY) {
                            recorderStateLocal = recorderState = RECORDER_STATE_STOPPING;
                        }
                        do {
                            try {
                                if (recorderStateLocal != RECORDER_STATE_IDLE) {
                                    recorderStateMonitor.wait();
                                }
                            } catch (InterruptedException ignore) {
                            /* Nothing to do */
                            }
                            recorderStateLocal = recorderState;
                        } while (recorderStateLocal == RECORDER_STATE_STOPPING);
                    }
                }
            }
            catch(IllegalStateException ee){}
        }

如果我评论mr.stopRecording（）; 项目可以成功运行
但我需要调用mr.stopRecording（）;
有人可以帮我解决这个问题吗？
