Optimizing build performance is important, especially for large-scale Apps, there is now an option to enable or disable the build Features as and when required. This is feasible because of the improved Android Gradle Plugin.
  10. Build Analyzer
    With the assistance of a Build Analyzer, the App Developer can understand and resolve bottlenecks in the Application’s Build.
