I am a software developer for solute GmbH. They are known in Germany for their price comparison website https://www.billiger.de (among other solutions).

I am doing Android-app development and am mostly using Stackoverflow to search for solutions for problems or discussions about problems.

As I have found many solutions here, I try to give back some of my own solutions to everybody, especially for previously unanswered questions, or if I find that a question only has insufficient or unhelpful answers.

The most noteworthy answer of mine seems to be for the question "What does google-services.json really do?" which is about the inner workings of the google-services gradle plugin, which I investigated.

What does google-services.json really do?

Apparently, this is still relevant after more than 5 years (still getting upvotes for this), so Google's documentation still seems to be lacking in visibility.
