4. Application Lifecycle

5. Launch
An app is launched whenever it is activated by the user while the process is in the NotRunning state.

6. Suspend
An app can be suspended when the user switches away from it or when the device enters a low power state. Most apps stop running when the user switches away from them.
When the user moves an app to the background, the OS waits a few seconds to see whether the user immediately switches back to the app. If the user does not switch back, the OS suspends the app.

7. Resume
A suspended app is resumed when the user switches to it or when the device comes out of a low power state.
If a suspended app is activated to participate in an app contract or extension, it receives the resuming event first, then the activated event.
When an app is suspended, it does not receive network events that it registered to receive. These events are not queued, they are simply missed. Therefore, your app should test the network status when it is resumed.
