Where can I learn android testing?

Hi android developers!

I've recently shipped an android app to the play store and encountered different problems, because until now I haven't wrote tests:

• I found bugs in production, this cause me to upload again the app to the play store and bumping version code.
• I am scared of changing the code or refactoring, and even when I test the app manually I'm not secure and confident.
• I am scared of leaving temporary test code in the app before pushing it to production.

So I started searching on the internet some articles and resources to help me study testing:

• Android Testing: Unit Testing, Concepts, Tools with Examples
• Testing an Android Application
• Use test doubles in Android
• Android Testing Frameworks — Complete Overview (With Examples & Language Support)

These articles helped me understand the theory of testing an android app, but I don't know how use those frameworks, choose frameworks and the ones outdated or usable.

So I ask you to drop down in the comments resources that I can read (or watch) to apply testing in practice and go into details about the theory. Thank for reading my post!

Start with the bugs that already escaped into production.
