Description

Summary:
It is a good practice to keep the codebase free of lint warnings, to make it more robust, performant, and readable.

Steps to reproduce:
Go to Analyze -> Inspect Code... -> select the Whole project

Expected behavior:
Minimized number of warnings, leaving only those whose fixation would crash the app itself.

Observed behavior:
Following warnings and errors are present in the codebase:

• Android - 1 errors and 264 warnings
• Groovy - 6 warnings
• Java - 1047 errors
• Kotlin - 23 warnings
• XML - 1 error and many more
