February 7, 2018
Android agent v5.17.0

New in this release

  • Added instrumentation support for Android Instant Apps The agent now detects and instruments all feature modules for an instant app. Because instant apps are typically side-loaded, users must add NewRelic.start() calls to each entry point activity in the module. We've also created a document to help integrate the agent into your Instant App. See Install the New Relic plugin for Android Instant Apps for more information.

Fixed in this release

  • Correctly restore any pre-existing unhandled exception handler when the agent shuts downs. Maintain the state of existing unhandled exception handlers when the agent returns to foreground.
  • Fixed instrumentation of abstract classes derived from Android SDK classes.
  • Fixed instrumentation failure when using certain Java 8 features, such as lambdas.
  • Updated instrumentation support for Dexguard 8 on Android Studio 3.0.
  • Enforce @SkipTrace with Android SDK-derived classes. Previously, onCreate() and onCreateView() could not be skipped from Activity, Fragment and other SDK classes.

December 14, 2017
Android agent v5.16.0

New in this release

  • MobileRequestError events now contain the response body returned in the network request response, if one exists. Response bodies will only be reported if the withHttpResponseBodyCaptureEnabled feature flag is enabled. HttpResponseBodyCapture is enabled by default. Response body data will be limited to the first 4096 bytes (the Insights attribute limit). A content type attribute will also be added to the event if a "content_type" header is found in the response.
  • MobileRequestError events now also contain any cross-application tracing (CAT) data returned in the response headers. See Introduction to cross-application traces for more information.

Fixed in this release

  • Stream file handle usage during class instrumentation has been tightened up to prevent potential resource leaks.
  • Proguard map detection of release variants when using AndroidStudio 3 has been restored.
  • Add content type parameter missing from HTTP error traces when instrumenting OkHttp2, OkHttp3 and Retrofit requests.
