Android application with different build type having same package name

Question

If I have like the following

Debug: com.test.project
Staging: com.test.project
Release: com.test.project

Of-course the release will be uploaded to the Play Store, Huawei Store, and Samsung Store -if possible- 1) Will this cause any type of problems? 2) If I created a firebase project to each build type,will I be getting any type of problems?

Answer 1

1. No

2. It's not possible to have two apps with the same ID and SHA-1 hash registered with Firebase. If you want to have two apps with the same ID, then you will need to sign them with different keys.
