Here is the release notes, known issues, and hot fix information for Android SDK 4.x for Experience Cloud Solutions:
a.target.sessionIdin the internal Analytics-for-Target hit sent to Adobe Analytics.
Acquisition - Added a new API,
Analytics.processGooglePlayInstallReferrerUrl(final String url), to support Google Play Install Referrer APIs.
For more information about the Install Referrer APIs, see Still Using InstallBroadcast? Switch to the Play Referrer API by March 1, 2020.
Adobe Target: All requests now include the client and the sessionId in the URL query parameters.
In-app Messaging: Fixed an issue where, when a message was triggered with an empty clickthrough URL, Android apps crashed.
Visitor ID Service: The
Visitor.getUrlVariablesAsync APIs no longer double-encode their return values.
The double-encoding was causing the return values from those APIs to be flagged by certain security reviews.
setPushIdentifierAPI call now sends a sync call to the Visitor ID Service every time it is called.
