Acceptance Criteria

• 1. If usage reporting is enabled every android build should produce a file with build statistics at platforms/android/analytics/build-statistics.json with content:

{
   "kotlinUsage": {
       "hasUseKotlinPropertyInApp": true,
       "hasKotlinRuntimeClasses": true
   }
}

• 2. With attached projects the properties in the should be changed.
• 3. An event with Action: Using Kotlin and label hasUseKotlinPropertyInAppData__true__ hasKotlinRuntimeClassesData__true. The values should be true/false according to the content of the build-statistics.json.

Make sure that usage reporting is enabled - tns usage-reporting enable. The flag --analyticsLogFile could be used for easier verification of the events that are sent.

For testing the properties use the attached project. To have hasUseKotlinPropertyInApp turn to false remove App_Resources/android/gradle.poperties. To have hasKotlinRuntimeClasses turn to false remove the jar file from App_Resources/android/libs. To test the feature use android@next.
