Google’s new Android App Bundle is a publishing format that offers a more efficient way for developers to build and release apps. It creates lean application APKs that are optimized for each device configuration, without refactoring. This means engineers need to code less, and users are happy to get a smaller download.

When it comes to your project succeeding, the quality of the code is secondary to user experience. That's because software is all about making users' jobs easier. If you start coding in a vacuum without understanding what your users need to do, you can't be sure you’re making the right thing. You need UX research.

When your application is scheduled to go to production, the development team may be asked what their regression testing strategy is. This is a perfectly reasonable question, but a lot of people have a hard time answering it. Don't overcomplicate it. Analyze your process, look at the other testing, and put it together.
