The application will create a customized service (extend from service) to keep generating random character every one second from A to Z using a new thread (DO NOT use application main thread). Here are the important characteristics: There should be two buttons, start service and stop service, shown on the app. The start button will trigger the random character generator service. The stop button will stop the service. Whenever the service status changed, you should display the current service status in the logcat. When random character generator service is running, the random character the service generated must be shown in the logcat. Here are the screenshots of the lab application:
