C#

After adding the iOS ACPCore NuGet package or the Android ACPLifecycle NuGet package, the Lifecycle extension can be added by this import statement

Copy
using Com.Adobe.Marketing.Mobile;
Copied to your clipboard
using Com.Adobe.Marketing.Mobile;

1. Register the Lifecycle extension:

Copy
public class TargetApp extends Application {

@Override
public void onCreate() {
    super.onCreate();
    MobileCore.setApplication(this);

    try {
        Lifecycle.registerExtension();
        // register other extensions
        MobileCore.start(new AdobeCallback () {
            @Override
            public void call(Object o) {
                MobileCore.configureWithAppID("yourAppId");
            }
        });    
    } catch (Exception e) {
        //Log the exception
    }
}
}
Copied to your clipboard
public class TargetApp extends Application {

@Override
public void onCreate() {
    super.onCreate();
    MobileCore.setApplication(this);

    try {
        Lifecycle.registerExtension();
        // register other extensions
        MobileCore.start(new AdobeCallback () {
            @Override
            public void call(Object o) {
                MobileCore.configureWithAppID("yourAppId");
            }
        });    
    } catch (Exception e) {
        //Log the exception
    }
}
}

2. In the onResume function, start the lifecycle data collection:

Copy
    @Override  
    public void onResume() {  
        MobileCore.setApplication(getApplication());
        MobileCore.lifecycleStart(null);
    }
Copied to your clipboard
    @Override  
    public void onResume() {  
        MobileCore.setApplication(getApplication());
        MobileCore.lifecycleStart(null);
    }

Setting the application is only necessary on activities that are entry points for your application. However, setting the application on each Activity has no negative impact and ensures that the SDK always has the necessary reference to your application. We recommend that you call setApplicationin each of your activities.

3. In the onPause function, pause the lifecycle data collection:

Copy
    @Override
    public void onPause() {
        MobileCore.lifecyclePause();
    }
Copied to your clipboard
    @Override
    public void onPause() {
        MobileCore.lifecyclePause();
    }

To ensure accurate session and crash reporting, this call must be added to every activity.

Swift

1. Register the Lifecycle extension with the SDK Core by adding the following to your app's application:didFinishLaunchingWithOptions: delegate method:

Copy
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
    // register the lifecycle extension
    ACPLifecycle.registerExtension();
}
Copied to your clipboard
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
    // register the lifecycle extension
    ACPLifecycle.registerExtension();
}

2. Start Lifecycle data collection by calling lifecycleStart: from within the callback of the ACPCore::start: method in your app's application:didFinishLaunchingWithOptions: delegate method.

If your iOS application supports background capabilities, your application:didFinishLaunchingWithOptions: method might be called when iOS launches your app in the background. If you do not want background launches to count towards your lifecycle metrics, then lifecycleStart: should only be called when the application state is not equal to UIApplicationStateBackground.

Copy
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
    // register the lifecycle extension
    ACPLifecycle.registerExtension();

    let appState = application.applicationState;            
    ACPCore.start {
        // only start lifecycle if the application is not in the background    
        if appState != .background {
            ACPCore.lifecycleStart(nil)
        }    
    }    
}
Copied to your clipboard
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
    // register the lifecycle extension
    ACPLifecycle.registerExtension();

    let appState = application.applicationState;            
    ACPCore.start {
        // only start lifecycle if the application is not in the background    
        if appState != .background {
            ACPCore.lifecycleStart(nil)
        }    
    }    
}

3. When launched, if your app is resuming from a backgrounded state, iOS might call your applicationWillEnterForeground: delegate method. You also need to call lifecycleStart:, but this time you do not need all of the supporting code that you used in application:didFinishLaunchingWithOptions::

Copy
func applicationWillEnterForeground(_ application: UIApplication) {    
    ACPCore.lifecycleStart(nil)
}
Copied to your clipboard
func applicationWillEnterForeground(_ application: UIApplication) {    
    ACPCore.lifecycleStart(nil)
}

In iOS 13 and later, for a scene-based application, use the UISceneDelegate's sceneWillEnterForeground method as follows:

Copy
func sceneWillEnterForeground(_ scene: UIScene) {
    ACPCore.lifecycleStart(nil)
}
Copied to your clipboard
func sceneWillEnterForeground(_ scene: UIScene) {
    ACPCore.lifecycleStart(nil)
}

For more information on handling foregrounding applications with Scenes, refer to Apple's documentation here

4. When the app enters the background, pause Lifecycle data collection from your app's applicationDidEnterBackground: delegate method:

Copy
func applicationDidEnterBackground(_ application: UIApplication) {    
    ACPCore.lifecyclePause()
}
Copied to your clipboard
func applicationDidEnterBackground(_ application: UIApplication) {    
    ACPCore.lifecyclePause()
}

In iOS 13 and later, for a scene-based application, use the UISceneDelegate's sceneDidEnterBackground method as follows:

Copy
func sceneDidEnterBackground(_ scene: UIScene) {
    ACPCore.lifecyclePause()
}
Copied to your clipboard
func sceneDidEnterBackground(_ scene: UIScene) {
    ACPCore.lifecyclePause()
}

For more information on handling backgrounding applications with Scenes, refer to Apple's documentation here

Objective-C

1. Register the Lifecycle extension with the SDK Core by adding the following to your app's application:didFinishLaunchingWithOptions: delegate method:

Copy
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    // register the lifecycle extension
[ACPLifecycle registerExtension];
    return YES;
}
Copied to your clipboard
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    // register the lifecycle extension
[ACPLifecycle registerExtension];
    return YES;
}

2. Start Lifecycle data collection by calling lifecycleStart: from within the callback of the ACPCore::start: method in your app's application:didFinishLaunchingWithOptions: delegate method.

If your iOS application supports background capabilities, your application:didFinishLaunchingWithOptions: method might be called when iOS launches your app in the background. If you do not want background launches to count towards your lifecycle metrics, then lifecycleStart: should only be called when the application state is not equal to UIApplicationStateBackground.

Copy
- (BOOL) application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    // register the lifecycle extension
    [ACPLifecycle registerExtension];

    const UIApplicationState appState = application.applicationState;
    [ACPCore start:^{
        // only start lifecycle if the application is not in the background
        if (appState != UIApplicationStateBackground) {
            [ACPCore lifecycleStart:nil];
        }
    }];
}
Copied to your clipboard
- (BOOL) application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    // register the lifecycle extension
    [ACPLifecycle registerExtension];

    const UIApplicationState appState = application.applicationState;
    [ACPCore start:^{
        // only start lifecycle if the application is not in the background
        if (appState != UIApplicationStateBackground) {
            [ACPCore lifecycleStart:nil];
        }
    }];
}

3. When launched, if your app is resuming from a backgrounded state, iOS might call your applicationWillEnterForeground: delegate method. You also need to call lifecycleStart:, but this time you do not need all of the supporting code that you used in application:didFinishLaunchingWithOptions::

Copy
- (void) applicationWillEnterForeground:(UIApplication *)application {
    [ACPCore lifecycleStart:nil];
}
Copied to your clipboard
- (void) applicationWillEnterForeground:(UIApplication *)application {
    [ACPCore lifecycleStart:nil];
}

In iOS 13 and later, for a scene-based application, use the UISceneDelegate's sceneWillEnterForeground method as follows:

Copy
- (void) sceneWillEnterForeground:(UIScene *)scene {
    [ACPCore lifecycleStart:nil];
}
Copied to your clipboard
- (void) sceneWillEnterForeground:(UIScene *)scene {
    [ACPCore lifecycleStart:nil];
}

For more information on handling foregrounding applications with Scenes, refer to Apple's documentation here

4. When the app enters the background, pause Lifecycle data collection from your app's applicationDidEnterBackground: delegate method:

Copy
- (void) applicationDidEnterBackground:(UIApplication *)application {
    [ACPCore lifecyclePause];
}
Copied to your clipboard
- (void) applicationDidEnterBackground:(UIApplication *)application {
    [ACPCore lifecyclePause];
}

In iOS 13 and later, for a scene-based application, use the UISceneDelegate's sceneDidEnterBackground method as follows:

Copy
- (void) sceneDidEnterBackground:(UIScene *)scene {
    [ACPCore lifecyclePause];
}
Copied to your clipboard
- (void) sceneDidEnterBackground:(UIScene *)scene {
    [ACPCore lifecyclePause];
}

For more information on handling backgrounding applications with Scenes, refer to Apple's documentation here

Registering the extension with Core

When using React Native, registering Lifecycle with Mobile Core should be done in native code which is shown under the Android and iOS (ACP 2.x) tabs.

When using Cordova, registering Lifecycle with Mobile Core must be done in native code which is shown under the Android and iOS tabs.

Starting and Pausing a lifecycle event

Add the OnApplicationPause in the MainScript with the following code:

Copy
private void OnApplicationPause(bool pauseStatus)
{
  if (pauseStatus)
  {
    ACPCore.LifecyclePause();
  }
  else
  {
    var cdata = new Dictionary<string, string>();
    cdata.Add("launch.data", "added");
    ACPCore.LifecycleStart(cdata);
  }
}
Copied to your clipboard
private void OnApplicationPause(bool pauseStatus)
{
  if (pauseStatus)
  {
    ACPCore.LifecyclePause();
  }
  else
  {
    var cdata = new Dictionary<string, string>();
    cdata.Add("launch.data", "added");
    ACPCore.LifecycleStart(cdata);
  }
}

iOS

1. Register the Lifecycle extension with the SDK Core by adding the following to your app's FinishedLaunching: delegate method:

Copy
public override bool FinishedLaunching(UIApplication app, NSDictionary options)
{
    ACPLifecycle.RegisterExtension();
    return base.FinishedLaunching(app, options);
}
Copied to your clipboard
public override bool FinishedLaunching(UIApplication app, NSDictionary options)
{
    ACPLifecycle.RegisterExtension();
    return base.FinishedLaunching(app, options);
}

2. Start Lifecycle data collection by calling LifecycleStart: from within the callback of the ACPCore::start: method in your app's FinishedLaunching: delegate method.

If your iOS application supports background capabilities, your FinishedLaunching: method might be called when iOS launches your app in the background. If you do not want background launches to count towards your lifecycle metrics, then LifecycleStart: should only be called when the application state is not equal to UIApplicationState.Background.

Copy
public override bool FinishedLaunching(UIApplication app, NSDictionary options)
{
    ACPLifecycle.RegisterExtension();

    // only start lifecycle if the application is not in the background
    var appstate = app.ApplicationState;
    if(appstate != UIApplicationState.Background)
    {
    ACPCore.LifecycleStart(null);
    }
    return base.FinishedLaunching(app, options);
}
Copied to your clipboard
public override bool FinishedLaunching(UIApplication app, NSDictionary options)
{
    ACPLifecycle.RegisterExtension();

    // only start lifecycle if the application is not in the background
    var appstate = app.ApplicationState;
    if(appstate != UIApplicationState.Background)
    {
    ACPCore.LifecycleStart(null);
    }
    return base.FinishedLaunching(app, options);
}

3. When launched, if your app is resuming from a backgrounded state, iOS might call your WillEnterForeground: delegate method. You also need to call LifecycleStart:, but this time you do not need all of the supporting code that you used in FinishedLaunching::

Copy
public override void WillEnterForeground(UIApplication uiApplication)
{
    base.WillEnterForeground(uiApplication);
    ACPCore.LifecycleStart(null);
}
Copied to your clipboard
public override void WillEnterForeground(UIApplication uiApplication)
{
    base.WillEnterForeground(uiApplication);
    ACPCore.LifecycleStart(null);
}

4. When the app enters the background, pause Lifecycle data collection from your app's DidEnterBackground: delegate method:

Copy
public override void DidEnterBackground(UIApplication uiApplication)
{
    base.DidEnterBackground(uiApplication);
    ACPCore.LifecyclePause();
}
Copied to your clipboard
public override void DidEnterBackground(UIApplication uiApplication)
{
    base.DidEnterBackground(uiApplication);
    ACPCore.LifecyclePause();
}

Android

1. Register the Lifecycle extension:

Copy
protected override void OnCreate(Bundle savedInstanceState)
{
    base.OnCreate(savedInstanceState);
LoadApplication(new App());
    ACPCore.Application = this.Application;
    ACPLifecycle.RegisterExtension();
}
Copied to your clipboard
protected override void OnCreate(Bundle savedInstanceState)
{
    base.OnCreate(savedInstanceState);
LoadApplication(new App());
    ACPCore.Application = this.Application;
    ACPLifecycle.RegisterExtension();
}

2. In the onResume function, start the lifecycle data collection:

Copy
protected override void OnResume()
{
    base.OnResume();
    ACPCore.LifecycleStart(null);
}
Copied to your clipboard
protected override void OnResume()
{
    base.OnResume();
    ACPCore.LifecycleStart(null);
}

Setting the application is only necessary on activities that are entry points for your application. However, setting the application on each Activity has no negative impact and ensures that the SDK always has the necessary reference to your application. You should set the application (ACPCore.Application = this.Application;) in each of your activities.

3. In the onPause function, pause the lifecycle data collection:

Copy
protected override void OnPause()
{
    base.OnPause();
    ACPCore.LifecyclePause();
}
Copied to your clipboard
protected override void OnPause()
{
    base.OnPause();
    ACPCore.LifecyclePause();
}

To ensure accurate session and crash reporting, this call must be added to every activity.
