adb shell dumpsys

• 命令集合

  adb shell dumpsys命令是用于打印出当前系统信息(更切确的说是dumpsys命令,因为adb shell只是为了进入手机或模拟器的shell内核,使其能够执行dumpsys命令),可以在命令后面加指定的service name(比如activity,location),如果不加则默认打印出设备中所有service的信息.

  下面列举使用最多的命令：

  # 列出最近使用过的任务栈，按时间从近到远排序：
  adb shell dumpsys activity
  # 查看Activity的相关信息
  adb shell dumpsys activity [包名]
  # 查看最上层的activity的View布局

  # 查看battery相关信息
  adb shell dumpsys batterystats [包名]
  # 查看Location相关信息:最近请求过定位的app和最近请求定位的地址
  adb shell dumpsys location
  # 导出GPU 呈现模式分析结果，最近大约100帧的渲染情况，直接在控制台打印

这里将逐一解释以上重点信息：

• Draw：测量绘制Display List的时间，也就是measure和layout的时间。
• Prepare：标示准备时间
• Process：OpenGL渲染Display的时间
• Execute：CPU等待GPU处理的时间，主线程被其他任务占用的时间，比如：处理业务逻辑之类的
