我在网上找到了一些资料:
echo 1/sys/devices/platform/flashlight.0/leds/flashlight/brightness
但是在我的 Nexus 7(刷了一个 AOSP)上,我找不到那个目录。
知道我应该写入哪个文件吗?这可行吗?
在 ls/sys/devices/platform
之后,我得到:

Android Jellybean 4.2 附带了一个新的二进制文件,可用于直接读取/写入系统设置提供程序,可通过命令行访问。
例如:为了增加屏幕的亮度,使用下面的命令:
adb shell settings put system screen_brightness 200

请注意,值的范围是 [0 - 255]
