How to shut down android device programatically using Intent or PowerManager API?

Question

I am trying to shutdown my custom android device programatically. I am using the below code to do the same, but it is restarting again.I want the device to be completely shut down.

Intent intent = new Intent("android.intent.action.ACTION_REQUEST_SHUTDOWN");
            intent.putExtra("android.intent.extra.KEY_CONFIRM", false);
            intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
            startActivity(intent);

How to achieve complete shut down i,e avoid auto restart?

Note: I have signed app with platform signatures. Placed it in /system/app Added <uses-permission android:name="android.permission.SHUTDOWN" /> permission in manifest.

If your device is rooted, you can use this code for shutdown

Java.Lang.Runtime.GetRuntime().Exec(new String[] { "/system/xbin/su", "-c", "reboot -p" });

and use this code for Reboot

Java.Lang.Runtime.GetRuntime().Exec(new String[] { "/system/xbin/su", "-c", "reboot now" });

I use this on Xamarin.Android

Try this code, it might help.

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

Thanks, I'll check this – user2879697 Jul 14 '16 at 14:19
I used this, but since I am calling this from service, its asking to use intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK). And if I use this flag, it just restarts. – user2879697 Jul 14 '16 at 14:34
