Tried to execute this command to reboot an Android TV Box:

{"jsonrpc":"2.0","id":1,"method":"System.Reboot" }

Got this message:

{"error":{"code":-32100,"message":"Failed to execute method."},"id":1,"jsonrpc":"2.0"}

And the device obviously did not reboot.

The permissions are ok:

{"jsonrpc":"2.0","id":1,"method":"JSONRPC.Permission" }

{"id":1,"jsonrpc":"2.0","result":{"ControlGUI":true,"ControlNotify":true,"ControlPVR":true,"ControlPlayback":true,"ControlPower":true,"ControlSystem":true,"ExecuteAddon":true,"ManageAddon":true,"Navigate":true,"ReadData":true,"RemoveData":true,"UpdateData":true,"WriteFile":true}}

Reboot is not implemented for Android. And "exit" iirc
