We recommend that you regularly perform an (external) code review.


Make use of linting

On Android you can use AndroidLint to improve the quality of your code.

Check if you are using outdated code. In Android Studio you can check this by selecting the following menu options:

  1. Kotlin

  2. Migration

  3. Usage of redundant or deprecated syntax or deprecated symbols

Avoid errors with automated testing. Follow the UI-testing guide for Android.
