 Complete packagename is unnecessary. For example, `adb shell dumpsys activity services org.mazhuang` will output services related with `org.mazhuang.demo1`, `org.mazhuang.demo2` and `org.mazhuang123`, etc.
 
+### Query package detail information

+command:
+
+```sh
+adb shell dumpsys package <packagename>
