Answer 1

I too wrote a small JS script which you can find https://hrankit.github.io/RoomSQLiteDifferenceFinder/

The process is pretty Simple.

1. Input the Expected error log in Expected column which is the Left One.

2. Input the Found error log in Found column which is the Right One.

3. Press Go. button. The error logs get converted to JSON.

4. Press Compare button and Voila, you have the difference you need.

This plugin finds out the difference in the two Expected and Found dump from the Android Studio Logcat.
