Material Animations

[Android Transition Framework][transition-framework] can be used for three main things:

1. Animate activity layout content when transitioning from one activity to another.
2. Animate shared elements (Hero views) in transitions between activities.
3. Animate view changes within same activity.

 /*Create an object of activity options to enable scene transition animation*/
 ActivityOptions options = ActivityOptions.makeSceneTransitionAnimation(this);

/*Pass it to startActivity() method as the second parameter*/
startActivity(intent, options.toBundle());

Jacoco setup for calculating kotlin test coverage (single module)

put the jacoco.gradle file below somewhere in your app repo (like scripts folder), and then add apply from: '../scripts/jacoco.gradle' to your module gradle file.

This will add additional gradle build tasks to your app, in the form of "testFlavourUnitTestCoverage" that you can run manually (e.g. testStagingDebugUnitTestCoverage) to generate the coverage.

You can edit def excludes definition to further exclude classes you don't want to generate the coverage for. If you have source in other folders beyond those specified in def coverageSourceDirs, add them.

This will generate both exec file used by external code quality analyzers (like Sonarqube), in the build/jacoco folder, and XML and HTML reports, in the build/reports/jacoco/flavourName folder.

solution based on - based on Sevastyan answer on StackOverflow


changes:
- take to account views offsets
- transformed to Kotlin
- now works on viewHolders
