I hope this helps . I am working on a kiosk project using an android tablet.If there is no input power to the kiosk for a long time then, the tablet will eventually shutdown.In order to auto-reboot the tab when the power comes back I modified the code in my tabs battery animation file(ipod) using: , Try this command too,
code :
echo 100 > /sys/devices/platform/nov_cabc.0/leds/lcd-backlight/brightness
echo 100 > brightness

Any of those help It is not possible to control this programatically with the current SDK.
The user has exclusive control over the brightness setting.
Linux shell commands behave strange with Runtime.exec() (screen command)

Linux shell commands behave strange with Runtime.exec() (screen command)

it fixes the issue The real problem is the way the command line is parsed: Java's Runtime.exec doesn't follow the same quoting rules as Bash. You should use the array version of the API instead:
code :
String[] command = {"bash", "-c", 
    "screen -p 0 -S screenname -X eval 'stuff \\\"cmd\\\"\\015'"};
Runtime.getRuntime().exec(command);
String[] command = {"screen", "-p", "0", 
    "-S", "10624.pts-2.koivu", "-X", "eval", "stuff \"cmd\"\\015"};

I hope this helps you . Essentially those steps would work... you would just have to figure out the right configure commands. Getting the ndk, checking out AOSP, even checking out CM would probably get you the cross-compilers you would need. AOSP and CM would probably be overkill but they include what you would get with the ndk. If you are only planning on porting utilities the ndk might be all you need though.
Hope that helps.

I think the issue was by ths following , Often times a laptop will have it's own screen key binding that turns on and off the display. If your laptop has no such key, try searching for programs other than xrandr that will do what you want. Ubuntu's default screensaver can assign a key that will automatically turn off and lock the screen.
Navigate System Settings > Keyboard > Shortcuts > System. Click the +, name your custom shortcut anything you want, and put as the command gnome-screensaver-command -la. Click Apply, then assign the shortcut you want to add.
