Flipper: App failing in release mode Android

[hackaprende]

When I run my app in release mode I am getting this:

location: class MainApplication

Can you please provide a full example of how your project is set up? Preferably a GitHub project we can check out, or otherwise a full list of the build settings.
If you have those information, please feel free to open a new issue.

I suspect that this is because you're using debugImplementation while importing the lib and so the classes are not found while compiling the release version. If you were to use implementation instead, this will probably compile, but it will bloat your release app. Another solution would be to have a separate Application class for the debug version of your project that includes Sonar while the main Application class excludes it.

@passy do you know if there are plans to include empty class definitions of the lib for a releaseImplementation?

A no-op version (similar to LeakCanary) for release implementations would be really useful to avoid duplicating the application class by buildType, are at the end any plans on adding it? Thanks!

@carlosmuvi Here is a Q&D temporary solution I came up with, would be better if this was implemented within the core library tho :/
