Join Chiu-Ki Chan for an in-depth discussion in this video Vector drawable: Create, part of Effective Android Testing for Mobile Developers.
- [Instructor] The last feature we are adding…to our app is favorites.…We want to be able to mark our favorite recipe with a star,…and we want the app to remember it.…First, let's create the star graphic.…We will use vector drawable.…So let's go to app slash build.gradle…and add the perimeter for it.…Click on build.gradle, and then at the top,…after version name at line 11,…add the perimeter VectorDrawables.useSupportLibrary.…
Set it to true.…Press sync now to do a gradle sync.…This means that we want to be able to use vector drawables…for devices that don't support it natively…by using the Support Library.…Next we will create our vector drawable.…Right click on the res folder, New, Vector Asset.…Click on the icon.…Select toggle, the last item on the left.…Choose the solid star with the name star.…
Press okay.…We'll rename it to ic_favorite_solid.…Press next, and press finish.…We're going to do this again to make the hollow one.…So res, New, Vector Asset.…Click on icon, toggle, star border.…Change the name to favorite_hollow.…

There's a difference between knowing how to implement testing and knowing when and why to do it. In this project-based course, get acquainted with best practices for testing Android apps by walking through a development workflow where testing is integrated throughout the process. As instructor Chiu-Ki Chan shows how to build the app, she explores the differences between JVM and on-device tests, explaining when to use each one. She also explores advanced techniques such as the MVP pattern. By demonstrating how testing fits into an app development workflow, she helps you bolster your ability to catch bugs—and determine where and when you should test.
