App lifecycle observer

Lib adds lifecycle observer for your app. Can add logic for method of pause app, resume app, start or close your app.

Features

• Handle of app states (onStartApp, onCloseApp, onPauseApp, onResumeApp, onAppConfigurationChanged).
• Add several listeners.
• Simple implementation.

Quick start

1. Implement gradle dependency:

add repositories:

buildscript {
    repositories {
        ...
        maven { url "https://jitpack.io" }
    }
}

add implementation

dependencies {
    implementation "com.github.danylo-pavenko:app-lifecycle-observer:<latest version>"
}

Latest version:

2. Call init method of AppLifecycleObserver.init() in your Application class.

class MyApp : Application {

  override fun onCreate(){
    super.onCreate()
    AppLifecycleObserver.instance?.init(this)
  }
}

3. Add listener as Adapter, use extension method AppLifecycleObserver.instance.addAppLifecycleListener.

fun setupListeners() {
        AppLifecycleObserver.instance.addAppLifecycleListener("tag_listener") {
            onAppStart { Log.d(TAG, "onAppStart") }
            onAppResumed { activity, byUnlocked -> Log.d(TAG, "onAppResumed") }
            onAppPaused { activity, byLocked -> Log.d(TAG, "onAppPaused") }
            onAppClose { Log.d(TAG, "onAppClose") }
            onAppConfigurationChanged { configuration -> Log.d(TAG, "onAppConfigurationChanged") }
        }
    }

End

Remove listeners

AppLifecycleObserver.instance.removeAllListeners() // remove all registered listeners
AppLifecycleObserver.instance.removeListener("tag_listener") // remove selected by tag of listener

Attention

If you will add for activity, need to call method removeListener(tag).

// key words: android, handle app states, handle app lifecycle, app close, app resume, app stop, app configuration changed
