Answer 1

As per the answer of @Maňish Yadav your app should be device owner to do rebooting due to security reasons.

You cannot do a reboot from an ordinary SDK application. Only applications signed with the system firmware signing key can do this. Copied from this answer,

You need the system key to sign your app. See this post for details;

If you're root on your device, you can follow this method to become device owner.

First, create a file device_owner.xml with following content:

Now do the following steps

• adb push device_owner.xml /sdcard/

• adb shell

• su

• cp /sdcard/device_owner.xml /data/system/

• cd /data/system/

• chown system:system device_owner.xml

• reboot

Note : Before rebooting device, make sure that you installed the application, which you are trying to make device owner. If you will not do, you will get boot animation for infinite time.
