Android Studio 3.4 Canary 3 available

Android Studio 3.4 Canary 3 is now available in the Canary and Dev channels.

If you have Android Studio set to receive updates on the Canary or Dev channel, you can get the update by choosing Help > Check for Updates (Android Studio > Check for Updates on Mac). Otherwise, you can download it here.

This update includes the following new features and changes in behavior:

• Lint now informs you when a non-public Java method is annotated with @JavascriptInterface.

This update includes fixes for several bugs, including the following:

• ExtractAnnotations in Gradle would cause an error when sources were missing.
• JacocoTask didn't consume runtime R-classes, and removed them instead, causing crashes.
• Building databinding in AOSP depended on the hardcoded paths of prebuilts SDK.
• Running lintDebug would throw NullPointerExceptions.
• Lint would incorrectly state that MediaMetadataCompat.Builder does not support custom keys.
• Processes couldn't be selected in Profiler when there were too many to display on the screen at once.
• IDE classpaths were not handled correctly for api.jar in libraries.
