Boot android, if there is power

Question

There is such a task - to include an android device, if there is power and turn off programmatically. I know that in order to turn off, you need a root (it will). But is there any way to turn on the device if the power is applied?

Answer 1

So, in my case I can use system scheduler for boot device at specialised time (f.e. 5:00 AM) and with root access shutdown device with this code

try {
    Runtime.getRuntime()
           .exec(new String[] { "su", "-c", "reboot -p" })
           .waitFor();
} catch (Exception ex) {
    ex.printStackTrace();
}
