Android 在命令行使用 adb shell dumpsys 相关命令

Posted 2022-12-04 花姓-老花

在平常开发中，为了更了解app使用栈相关情况，是不是使用到了adb shell dumpsys命令【注：操作系统是window】。

在cmd 输入adb提示

这时需要配置其环境变量，需要在环境变量path中配置下载好sdk的platform-tools目录路径：比如G:\\androidSdk\\platform-tools即可

命令：

1、adb shell dumpsys activity [包名]

查看指定app activity相关信息，如图：

2、adb shell dumpsys batterystats [包名]

查看battery（电池）使用相关信息

3、adb shell dumpsys location

查看location相关信息

4、adb shell dumpsys 查看内存

Android程序内存被分为2部分：native和dalvik

    dalvik就是Java堆，创建对象就在这里分配的

    bitmap是直接在native上分配的

    app内存大小=native+dalvik 不能超过最大限制值

app内存使用情况 adb shell dumpsys + 包名

    

想知道 adb shell dumpsys 有哪些命令可以用，可以使用adb shell service list来查看

有兴趣可以执行一下 adb shell dumpsys + 上面打印service

比如下面

// 查看Activity相关信息
adb shell dumpsys activity
// 查看CPU相关信息
adb shell dumpsys cpuinfo
// 查看电池使用信息
adb shell dumpsys battery
//查看Window的相关信息,最后部分可以看到分辨率的信息
adb shell dumpsys window

想更了解更多用法，上面有些service还支持额外参数，可以在其后面使用 -h 查看帮助信息，如：

// 查看package这个service的帮助信息
adb shell dumpsys package -h
// 查看activity这个service的帮助信息
adb shell dumpsys activity -h
