Version 4.0.1 (30th April 2021)​

Bug fixes​

  • Fixed predefined events to publish their custom parameters with the correct dimensions.

Version 4.0.0 (22nd April 2021)​

Changed​

  • The implementation for standard events changed significantly. Each standard event now has an associated class and should be created via an instance of this class.
  • Standard events now carry built-in dimensions next to the three custom dimensions.
  • A UserEvent now takes a EventDetails instance instead of a String as the name parameter. You can create a EventDetails instance from a string, leaving category, element, and action empty.
  • There is now a short delay before sending user events to batch them.
  • The justtrack SDK is now licensed under the MIT license.
  • Added the current version name (if available) to the app version send to the backend.
  • The JustTrackSdkBuilder has been simplified and now only depends on an Activity or Application.

  • Added a static class justtrack to record application start and load times before initializing the SDK.

Removed​

  • Removed setEnableActivityTracking from the SdkBuilder interface.

Version 3.2.0 (6th April 2021)​

Changed​

  • AttributionResponse#getCampaign(), AttributionResponse#getChannel() and AttributionResponse#getNetwork() now return Campaign, Channel and Network interfaces instead of the old IdString interface.
  • RetargetingParameters#getUrl() was replaced by RetargetingParameters#getUri() to allow URIs with an unknown protocol (e.g., your app name) to be returned.

Added​

  • Added Campaign, Channel and Network interfaces.
  • Added Campaign#getType() to retrieve the type of a campaign.
  • Added Channel#isIncent() to retrieve the incent flag of the channel.
  • Added support for a preliminary retargeting result. This allows you to already display some welcome screen while the SDK is still waiting for the retargeting attribution to be confirmed by the justtrack backend (as this can take a few seconds). Therefore there is a new interface PreliminaryRetargetingParameters, a new method JustTrackSdk#getPreliminaryRetargetingParameters(), a new listener interface PreliminaryRetargetingParametersListener and a new method JustTrackSdk#registerPreliminaryRetargetingParametersListener(PreliminaryRetargetingParametersListener) to register said listener. After obtaining an instance of PreliminaryRetargetingParameters, you can validate() them to check whether the user did really a retargeting campaign or whether they e.g. crafted the Intent by hand.

Version 3.1.0 (16th March 2021)​

Changed​

  • The SDK now fetches the attribution again after 5 seconds (default, can be changed) after a re-attribution opportunity was detected.

Added​

  • Added setReFetchReAttributionDelaySeconds to the SDK builder to control when attributions are fetched a second time after a re-attribution opportunity was detected.

Version 3.0.0 (22nd February 2021)​

Changed​

  • Renamed various parts of the attribution response:
    • uuid > userId
    • subId > sourceId
    • subAppId > sourceBundleId
    • adSetId > adsetId (small S)
    • recruiter.clientId > recruiter.packageId
  • Added recruiter.userId, recruiter.platform, installId, userType, sourcePlacement to the attribution response
  • Updated okhttp dependency to 3.14.9 and play-services-ads dependency to 19.7.0
  • JustTrackSdkBuilder and ExistingJustTrackSdkBuilder now take an Intent as the second parameter.
  • Starting with this version, you have to implement Activity#onNewIntent(Intent) to allow the SDK to detect receiving intents while the app is already running.

Added​

  • Added setInactivityTimeFrame(long) and setReAttributionTimeFrame(long) to the SdkBuilder interface. Use it to specify how often we need to fetch for a new (re-)attribution. By default we will fetch a new attribution every 14 days or after the SDK wasn't initialized for more than 48 hours.
  • Added getRetargetingParameters to the JustTrackSdk interface. It provides the retargeting parameters the app was started with (if any, otherwise null).
  • Added registerAttributionListener and registerRetargetingParametersListener to the SDK as well as needed companion types.
  • Added onNewIntent to the SDK to notify it about new intents (if you don't call setIntent in your activity).

Version 2.4.2 (11th January 2021)​

Changed​

  • The SDK now waits for some time before retrying requests.
  • Allow the advertiser ID to be missing if we have a tracking ID.

  • Added integrateWithIronSource() to JustTrackSdk interface.
  • Added setEnableIronSourceIntegration(boolean) to SdkBuilder interface.
  • When you have the IronSource SDK integrated into your app, you can now automatically sent the userId to IronSource as well as subscribing to impression events as user events by calling integrateWithIronSource() or setEnableIronSourceIntegration(true).

Version 2.3.3 (22th October 2020)​

Changed​

  • The Logger interface was changed and supports additional fields now.
  • The SDK now automatically sends logs to the justtrack backend.
  • The SDK now sends additional information about the install referrer to the backend.

Bug fixes​

  • The SDK now correctly reports the Version of the app upon install.

Version 2.3.2 (8th October 2020)​

Added​

  • Added setFirebaseInstanceId and publishFirebaseInstanceId methods to forward a firebase ID to the justtrack backend.

Version 2.3.1 (17th September 2020)​

Changed​

  • The SDK now automatically publishes SESSION_APP_OPEN events each time the SDK detects an app launch.

Version 2.3.0 (7th September 2020)​
