问题 I am attempting to make an application that reads text messages. The application works fine, when I get a text message, the message is displayed in a toast along with the phone number. The problem is, even with the application closed, ie not in the foreground, it still shows the toast when I get a text message. I have used a task killer application, and it still shows the toast. The only way to not show the toast is to unistall the application. I am using this website as a tutorial http://www
