有两种方法可以查看service list:

1. adb shell dumpsys

输出信息的开始部分就是所有运行的service，如下：

Currently running services:

2. adb shell service list

输出结果如下：

查询到运行的system service后，就可以在dumpsys后面加上service的名字，查看指定的service信息。

adb shell dumpsys window（最后部分可以看到分辨率的信息）

有些service能够接收额外的参数，我们可以使用-h查看帮助信息。

adb shell dumpsys package -h
