Instant App modularization

Question

I've been working on instant app for a few days. I didn't get it compiled yet.

The project is split into instant , installed , base , export , preview as features.

In export module relies on some layouts, string resources from the base module. Then installed will compile base and export module. Everything just works

However, in preview does the same thing like some layouts, string resources from the base module. Both export and preview do different things but use the same resources. instant module will compile base , preview but get an error below

Unresolved reference: id
Unresolved reference: layout
Unresolved reference: anim

Is that a expected behavior from build tool, or a bug from build tool?

Answer 1

When building an instant app, the feature module's R class doesn't contain resource identifiers from the base feature. For all resources that come via the base feature, you should change the import to the base feature R class. (base.R instead of preview.R)
