The mParticle SDK automatically monitors the “application state” of your app and forwards data to mParticle via a dedicated event type called Application State Transition (AST). Each AST event includes a transition_type property, describing the state change.
The transition types for the iOS SDK are:
application_initialized: The application has been opened by the user.application_background: The user has moved the app to background, but it is still open.application_foreground: The user has brought the app back to the foreground.One of the main uses of AST events is to track when a user installs or upgrades your app. Each output integration handles app installation tracking differently: some partners simply infer that the app was installed when they first begin to receive data with a Device ID that hasn’t been seen previously while others receive a specific install event.
AST events with type application_initialized include two boolean properties to help track installs:
is_first_runis_upgrademParticle uses these properties to determine how to forward AST events to your connected outputs.
By default, the is_first_run and is_upgrade properties discussed above are automatically detected and set by mParticle.
However, if you have your own criteria you want to use to define installs and upgrades, you can manually set the “install type” in the MParticleOptions object when you initialize the SDK.
The install type options are:
MPInstallationType.knownInstallMPInstallationType.knownUpgradeMPInstallationType.knownSameVersionMPInstallationType.autodetect (default)MParticleOptions *options = [MParticleOptions optionsWithKey:@"REPLACE WITH APP KEY" secret:@"REPLACE WITH APP SECRET"];
options.installType = MPInstallationTypeKnownInstall;
[[MParticle sharedInstance] startWithOptions:options];let options = MParticleOptions(key: "REPLACE WITH APP KEY", secret: "REPLACE WITH APP SECRET")
options.installType = .knownInstall
MParticle.sharedInstance().start(with: options)ASTs with type application_initialized have a successfully closed parameter which tracks whether the previous user session was successfully closed. This parameter helps mParticle to successfully record sessions when users force quit the app. See Force Quit for more.
The mParticle platform tracks user sessions. Sessions track a common pattern, in which a given user opens an app and interacts with it for a period of time, then moves on to another app, or stops using their device. Various output integrations use sessions to group user interactions. All events tracked during a session will also share a Session ID. The mParticle platform translates the sessions it detects into a consumable format for each output.
The mParticle iOS SDK provides APIs to allow you to customize the measurement of sessions.
When a user launches your app, the mParticle SDK will begin a new session. This session is maintained for as long as your app is in the foreground and all events logged during this time will be associated with the session.
If a user navigates away, or sends your app to the background, the SDK starts a timer to expire the current session. If the user brings your app back to the foreground before the session times out, the same session is continued. Otherwise, the session will expire and a new session will begin the next time the app is used.
By default, the session timeout is 60 seconds, but can be customized with a minimum timeout of 1 second and no maximum.
//Set the session timeout in seconds up to a max of 120
[MParticle sharedInstance].sessionTimeout = 60;If an application is allowed to continue running in the background for long periods of time, such as media playing or recording, and map based applications, the current session will expire based on the session timeout even if the media or maps operations are still active. If you need the background activity to be included in the user’s session length, you can disable automatic tracking and manually start/end sessions.
//Disable automatic tracking
MParticleOptions *options = [MParticleOptions optionsWithKey:@"foo-key" secret:@"foo-secret"];
options.automaticSessionTracking = NO;
[[MParticle sharedInstance] startWithOptions:options];
//Manually begin or end a session
[[MParticle sharedInstance] beginSession];
[[MParticle sharedInstance] endSession];We’ve observed a common pattern where users launch an app, interact with it, and then forcibly terminate the app, rather than allowing it to remain in the background. The mParticle SDK handles this situation gracefully.
When an app is terminated before a session had the chance to end itself, the SDK will end that session and start a new one the next time the app is launched.
The SDK logs when an app is launched, sent to the background, resumed to the foreground, and/or terminated. Those state transitions are not only sent to the server, but also they help to identify user sessions.
You can register to receive notifications from the mParticle SDK when a new session begins or when the current session is about to end. The registration is done in the NSNotificationCenter using the mParticleSessionDidBeginNotification and mParticleSessionDidEndNotification name constants. The notifications contain a userInfo dictionary containing the Session ID. You can access its value by using the mParticleSessionId key constant.
- (void)registerForSessionNotifications {
NSNotificationCenter *notificationCenter = [NSNotificationCenter defaultCenter];
[notificationCenter addObserver:self
selector:@selector(handleSessionDidBegin:)
name:mParticleSessionDidBeginNotification
object:nil];
[notificationCenter addObserver:self
selector:@selector(handleSessionDidEnd:)
name:mParticleSessionDidEndNotification
object:nil];
}
- (void)handleSessionDidBegin:(NSNotification *)notification {
NSDictionary *userInfo = [notification userInfo];
NSLog(@"New session has begun. Id: %@", userInfo[mParticleSessionId]);
}
- (void)handleSessionDidEnd:(NSNotification *)notification {
NSDictionary *userInfo = [notification userInfo];
NSLog(@"Session id %@ will end.", userInfo[mParticleSessionId]);
}If you use embedded kits, keep in mind that most kits perform their own session and install tracking, independently of mParticle. While it is impossible to guarantee that session times will match between mParticle and a kit partner, you can sometimes tweak the kit settings to help sessions line up. For example, the Braze kit provides a session timeout setting that works similarly to mParticle’s own, and you may wish to set it to match your mParticle session timeout.
