插入电源时如何使Android设备启动? [英] How to make Android device boot when power is plugged in?

问题描述

我需要将它用于三星平板电脑.

I need to use this for a Samsung Tablet.

通常，如果设备已关闭并且正在连接 USB 数据线，则显示屏会唤醒几秒钟，显示动画电池.相反，我想让它启动.

Usually if the device is switched-off and the USB cable is being connected the display will wake up for some seconds showing an animated battery. Instead I want to let it boot.

我怀疑这与金属很接近.我必须在哪里进行修改?在内核中，在Android平台中，还是隐藏在厂商的一些专有代码中?

I suspect this is close to the metal. Where do I have to make a modification? In the kernel, in the Android platform, or is this hidden in some proprietary code of the manufacturer?

推荐答案

XDA 上的一个成员发布了一个 解决方案 似乎适用于某些三星设备.

A member on XDA has posted a solution for this which seems to work on some Samsung devices.

这个想法是用一个可以启动手机的自定义脚本替换电池图标的脚本(当然，一旦插入设备，它就会出现).为了使这项工作找到 /system/bin/playlpm.将旧的 playlpm 重命名为 playlpm.bak 并将其替换为以下脚本:

The idea is to replace the script for the battery icon (which will appear of course as soon as the device is plugged in) with a custom script that will boot the phone. To make this work locate /system/bin/playlpm. Rename the old playlpm to playlpm.bak and replace it with the following script:

#!/system/bin/sh
/system/bin/reboot
