Reboot Android Device running 4.0

Question

I have set permissions in the manifest:

<uses-permission android:name="android.permission.REBOOT" />

I call the following lines to reboot device:

Intent intent = new Intent(Intent.ACTION_REBOOT);
sendBroadcast(intent);

Since I have root permissions in the emulator, I am curious why I encounter the following error:

 Permission Denial: not allowed to send broadcast android.intent.action.REBOOT from pid=963, uid=10046

REBOOT permission is only granted to applications having a platform signature or being a system application.

being root probably allows you to run commands as root, but your app still is not. (you could sudo call the shutdown command, though)

Do you have any advice to get a custom mod onto an emulator so that my app has the same signing cert as the OS? – Roy Hinkley Sep 17 '12 at 15:13

In case anyone is still looking and we indeed are talking about rooted devices, read this answer.

The following code sample should do it (added per request):

Process rebootProcess = null;
try
{
    rebootProcess = Runtime.getRuntime().exec("su -c reboot now");
}
catch (IOException e)
{
    // Handle I/O exception.
}

// We waitFor only if we've got the process.
if (rebootProcess != null)
{
    try
    {
        rebootProcess.waitFor();
    }
    catch (InterruptedException e)
    {
        // Now handle this exception.
    }
}
