Answer 1

Unfortunately its not possible if you neither have root permission nor your app is system app. If your app is a System app then you can do following:

In your Manifest file put following permission:

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

Use following code to restart:

PowerManager pm = (PowerManager) getSystemService(Context.POWER_SERVICE);
pm.reboot(null);
