全志行车记录仪里面FireEyepublic.apk反编译的分析（六）——时间水印分析

接（四）handler分析：

      case 4:
	  	FireEye.UpdateRecordingTime();
		break;

原始代码：

  private void UpdateRecordingTime()
  {
    if (!this.mRecordingStatus);
    while (true)
    {
      label7: return;
      long l1 = System.currentTimeMillis();
      millisecondToWaterMarkIndex(l1);
      long l2 = l1 - this.mRecordingStartTime;
      if (l2 < 0L)
      {
        StopRecording();
        StartRecording();
      }
      String str = millisecondToTimeString(l2, false);
      if (CODE_DEBUG)
        Log.d(TAG, "milli second : " + str);
      this.mRecordingTime.setText(str);
      if (l2 < this.mRecordingRepeatTime)
        break label184;
      if (this.mConfig.mMotionStatus != 0)
        break;
      LoopRecording();
      this.mHandler.sendEmptyMessageDelayed(4, 500L);
    }
    if (this.LastDet > 5)
    {
      this.openMotionDetect = true;
      StopRecording();
      this.mStartWork.setBackgroundResource(2130837584);
    }
    while (true)
    {
      this.LastDet = 0;
      break label7:
      LoopRecording();
      this.mHandler.sendEmptyMessageDelayed(4, 500L);
    }
    if (this.mFlickerFlags == 0)
    {
      label184: this.mFlickerFlags = 1;
      this.mRecordingFlag.setCompoundDrawablesWithIntrinsicBounds(2130837575, 0, 0, 0);
    }
    while (true)
    {
      this.mHandler.sendEmptyMessageDelayed(4, 500L);
      if (this.StartDet > 20);
      this.openMotionDetect = true;
      StopRecording();
      this.mStartWork.setBackgroundResource(2130837584);
      this.StartDet = 0;
      break label7:
      this.mFlickerFlags = 0;
      this.mRecordingFlag.setCompoundDrawablesWithIntrinsicBounds(2130837576, 0, 0, 0);
    }
  }

整理后的代码：

  private void UpdateRecordingTime()
  {
    if (mRecordingStatus){  //处于录制状态
      long l1 = System.currentTimeMillis();
      millisecondToWaterMarkIndex(l1);  //时间水印
      long l2 = l1 - mRecordingStartTime;
      if (l2 < 0L)//录制时间小于0，重新录制
      {
        StopRecording();
        StartRecording();
      }
      String str = millisecondToTimeString(l2, false);
      if (CODE_DEBUG)
        Log.d(TAG, "milli second : " + str);
      mRecordingTime.setText(str);

      if (l2 < mRecordingRepeatTime){
 	 mFlickerFlags = 1;
        mRecordingFlag.setCompoundDrawablesWithIntrinsicBounds(R.drawable.camera_recording_label_green, 0, 0, 0);
      }
	  
      if (mConfig.mMotionStatus == 0){//没有打开移动侦测的情况下，循环录像，每500ms更新时间
	      LoopRecording();
	      mHandler.sendEmptyMessageDelayed(4, 500L);
      	}
    }
	
    if (this.LastDet > 5)//这个LastDet没搞清楚什么意思,感觉像是检测运动侦测的幅度
    {
      openMotionDetect = true;
      StopRecording();
      this.mStartWork.setBackgroundResource(R.drawable.camera_stop_work);
    }
    else{
      LoopRecording();
      mHandler.sendEmptyMessageDelayed(4, 500L);
    }	

    this.LastDet = 0;

// 一段段的来分析可以简化复杂度
	
    if (mFlickerFlags != 0)
    {
      mFlickerFlags = 0;
      mRecordingFlag.setCompoundDrawablesWithIntrinsicBounds(R.drawable.camera_recording_label_red, 0, 0, 0);
    }
    mHandler.sendEmptyMessageDelayed(4, 500L);
      if (StartDet > 20);
      		openMotionDetect = true;
      StopRecording();
      mStartWork.setBackgroundResource(R.draw.camera_stop_work);
      StartDet = 0;
  }

由于项目比较赶，只是大概的修改方便阅读，如果大家发现逻辑上的错误，请指正，以免误导其他读者！谢谢！其实正真有用的函数被封在库里了：refreshWaterMark

涉及的知识点：

java calendar类的用法。这个估计一般都知道，但是我真心不知道，平常都是用c比较多，java不是很熟，得从头来。

上面有简单的用法

java.util.Calendar

        

Date localDate2 = new Date(paramLong);
Calendar localCalendar2 = Calendar.getInstance();
localCalendar2.setTime(localDate2);
int i4 = localCalendar2.get(Calendar.Year);

真正的时间水印没有解决，后面再baidu一下，先看下速度是怎么获取的:

import android.location.Criteria;
import android.location.Location;
import android.location.LocationListener;
import android.location.LocationManager;

 private Location currentLocation;

 private int getCurrentSpeed()
  {
    if (currentLocation != null)
    {
       speedMS = currentLocation.getSpeed();
       speedKMH = (3.6D * speedMS);
    }
    return (int)speedKMH;
  }

用mtk自带的gps不知道在这里会不会有问题？

以下是网上搜索到的时间水印资料：

这种属于纯上层的添加，下面还有一种基本上也是这样添加。

通过查找资料，得出一个结论，那就是首先得把Android4.4上的camera流程梳理一变。
