#Android 如何快速定位当前页面是哪个Activity or Fragment
(1)查看当前activity：adb shell “dumpsys window w | grep name”
(2)查看当前栈顶的activity：adb shell dumpsys activity |grep mFocusedActivity
(3)通过logcat查看页面情况,as中通过Layout Inspector查看当前页面的调用栈
(4)adb shell dumpsys activity activities |sed -En -e ‘/Running activities/,/Run #0/p’
