The Android SDK will now collect an app build identifier when an app crashes, which will be displayed in parentheses beside the version number in the Crash Details page in RPM. This value defaults to the string versionCode that is specified in the app's AndroidManifest.xml. If versionCode is not specified the build identifier not be displayed.
A new API method withBuildIdentifier(String) was added to allow specifying a custom app build identifier, overriding the default value pulled from versionCode.
Updates to unique ID management to improve accuracy of unique device counts.
