通过ADB拔出设备的电源：“找不到服务” [英] Unplugging the device via ADB: "can't find service"

问题描述

我必须测试我的应用在打ze模式下的行为。根据文档，我首先必须通过在终端中输入以下命令，设备认为已将其拔出：

I have to test how my app behaves in doze mode. According to the documentation, I first must make the device think it's unplugged by entering the following command in the terminal:

$ adb shell dumpsys battery unplug

但是什么也没发生，它会记录：

However, nothing happens and it logs:

找不到服务：电池

Can't find service: battery

我该怎么办？

推荐答案

日志中没有指出电池服务（这可能是特定于设备的。）

There is no battery service as the log points out (this may be device specific).

输入以下命令以查找现有的电池相关服务：

Enter the following command to find existing battery related services:

$ adb shell service list | grep battery

它会导致类似这样的情况

it will result in something like this

$ adb shell service list | grep battery
88      batterymanager: [android.app.IBatteryService]
107     batterystats: [com.android.internal.app.IBatteryStats]
114     batteryproperties: [android.os.IBatteryPropertiesRegistrar]

管理电池应该使用 batterymanager 。

$ adb shell dumpsys batterymanager

输出（如果已插入已充电的USB）

outputs (in case the usb charged is plugged)

Current Battery Service state:
  (UPDATES STOPPED -- use 'reset' to restart)
  AC powered: false
  USB powered: true

然后，当您键入

$ adb shell dumpsys batterymanager unplug

并再次运行上一个命令，它输出

and run the previous command again, it outputs

Current Battery Service state:
  (UPDATES STOPPED -- use 'reset' to restart)
  AC powered: false
  USB powered: false

验证您应该使用 batterymanager 服务而不是 battery 。

Which validates that you should use the batterymanager service instead of battery.
