[jcesarmobile]

Platforms affected

Android

What does this PR do?

Increases old plugin compatibility by adding 'app/src/main' to all plugin source-file tags that didn't include it, so the files are copied to the new Android Studio structure

What testing has been done on this change?

Tested with cordova plugin add https://github.com/OutSystems/cordova-plugin-audiorecorder.git as it uses source-file for images and xml

Really nice!

Wondering if this should be considered a breaking change or not?

[purplecabbage]

LGTM!
I think this is just a minor.bump as we are not changing apis, just how some missing input is treated.

[jcesarmobile]

Yeah, I don't think it's a breaking change.
If plugins were updated to use the new path, then it won't affect them
If plugins were updated to use resource-file tag instead of source-file tag, then it won't affect them
Plugins with old paths and using source-file tag instead of resource-file tag for resources are currently broken on cordova-android 7.1.0 and this change will make them work as they used to, so shouldn't be breaking change.

[dpogue]

I think we should really strongly be encouraging plugins to update to the new project structure, but this makes sense as a move to allow people to update to the latest cordova-android without breaking existing plugins.

[jcesarmobile]

Agree, but we should start by updating core plugins and docs
