How to shutdown an Android mobile programmatically?

Question

Is it possible to shutdown the mobile programmatically. that is with out using su commands..

Answer 1

It is possible, but you need a Rooted Android device with Superuser access. You can't do it without Root unless your app is signed with the System Firmware Key. Try using the following code:

Shutdown:

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

Reboot:

Same code, just use "reboot" instead of "reboot -p".

[On an other note: I read somewhere that these commands do not work on Stock HTC ROMs, but haven't confirmed myself]
