+NOTE:
+On Android 3.1 and higher, when your app is first installed on the device, it is in a
+“stopped” state. This has nothing to do with onStop() of any activity. While in the
+stopped state, your manifest-registered BroadcastReceivers will not receive any
+broadcasts.
+To get out of the stopped state, something on the device, such as another app (that
+itself is not in the stopped state), must use an explicit Intent to invoke one of your
+components.
+The most common way this happens is for the user to tap on a launcher icon
+associated with your launcher activity. Under the covers, the home screen’s launcher
+will create an explicit Intent, identifying your activity, and use that with
+startActivity(). This moves you out of the stopped state.
+As noted above, you start off in the stopped state. Once you are moved out of the
+stopped state, via the explicit Intent, you will remain out of the stopped state until
+one of two things happens:
+1. The user uninstalls your app
+2. The user “force-stops” your app
