```
public final class POBAppStateMonitor
 implements POBAppStateMonitoring, Application.ActivityLifecycleCallbacks
                    
```
This class monitors the lifecycle events of the host application's activities to determine whether the app is in the foreground or background. It uses the ActivityLifecycleCallbacks to track activity lifecycle events and determine the app's state.

  - release
```
 Unit release()
```
    Releases the lifecycle monitor and unregisters the callbacks.
  - addAppLifecycleListener
```
 Unit addAppLifecycleListener(POBAppStateMonitor.POBAppLifecycleListener listener)
```
    Sets the listener to receive lifecycle events.
    
    Parameters:
    
    listener - POBApplicationLifecycleListener to receive lifecycle events.
  - removeAppLifecycleListener
```
 Unit removeAppLifecycleListener(POBAppStateMonitor.POBAppLifecycleListener listener)
```
    Removes a listener from receiving lifecycle events.
    
    Parameters:
    
    listener - The listener to be removed from receiving lifecycle events.
  - onActivityCreated
```
 Unit onActivityCreated(Activity activity, Bundle savedInstanceState)
```
  - onActivityStarted
```
 Unit onActivityStarted(Activity activity)
```
    Called when an activity is started. If the app is not in the foreground, it notifies the listener that the app is in the foreground. It also resets the activity start timer and removes any pending handler callbacks.
  - onActivityResumed
```
 Unit onActivityResumed(Activity activity)
```
  - onActivityPaused
```
 Unit onActivityPaused(Activity activity)
```
  - onActivityStopped
```
 Unit onActivityStopped(Activity activity)
```
    This lifecycle callback posts a delayed runnable to check if the app is in the background. If the app remains inactive which means no onActivityStarted callback for more than FOREGROUND_DELAY duration, it notifies the listener that the app is in the background.
  - onActivitySaveInstanceState
```
 Unit onActivitySaveInstanceState(Activity activity, Bundle outState)
```
  - onActivityDestroyed
```
 Unit onActivityDestroyed(Activity activity)
```
  - getInstance
```
 final static POBAppStateMonitor getInstance(Application application)
```
    Returns the singleton instance of the POBAppStateMonitor. If the instance is not already created, it initializes a new instance.
    
    Parameters:
    
    application - The application instance to register lifecycle callbacks.
    
    Returns:
    
    The singleton instance of POBAppStateMonitor.
