安卓控件获取器uiautomatorviewer初体验："unable to connect to the adb. check if adb is installed correctly"

解决方法：转自:https://plus.google.com/108487870030743970488/posts/2TrMqs1ZGQv

Challenge Accepted:
1. ScreenshotAction class has this in its run() method when !DebugBridge.isInitialized()

2. DebugBridge is not initialized when it can't find the "platform-tools" folder which it gets via the property ""com.android.uiautomator.bindir"

3. The above property is set (in windows) in uiautomatorviewer.bat:
call %java_exe% Djava.ext.dirs=%javaextdirs% -Dcom.android.uiautomator.bindir= -jar %jarpath% %

4. Strange that it is empty isn't it. Changing the above line in my case to:
call %java_exe% -Djava.ext.dirs=%javaextdirs% -Dcom.android.uiautomator.bindir=H:\android-sdk\tools -jar %jarpath% %

This solves the issue, and UI Automator Viewer is up. The app is pretty neat with all the "mouse over""find view" feature.
