Roboguice, ADT 14+, and Android library projects

Question

Roboguice is such a neat little tool to tidy up boilerplate Android view code.

I loved using the @InjectView annotation so that I didn't have to initialize each and every view field in the onCreate() method of my Activities like this:

@InjectView(R.id.title) TextView title;

As part of Google's sweeping changes to library projects for ADT 14+ (which on the whole are a welcome improvement), id fields in generated R classes are no longer final.

So now when you want to use Roboguice inside of library projects, the @InjectView annotations no longer compile because annotations are processed at compile time, and R.id.title is no longer final.

Bummer...

Anybody else out there using Roboguice and have a creative workaround?

Android Annotations supports a resource name based injection with a compile-time check.

Still annoying for refactoring support, but at least a compile time error would be generated! – Jonathan Schneider Oct 18 '13 at 02:27

I guess you best bet is to follow this bug report on roboguice to see what kind of solution they come up with: http://code.google.com/p/roboguice/issues/detail?id=139&sort=-id

I suppose there is just no workaround right now. Unfortunate. – Jonathan Schneider Nov 15 '11 at 06:53

RoboGuice's recommendation is to replace the ID references by TAG ones instead: http://code.google.com/p/roboguice/wiki/LibraryProjects

Noted, although I would consider this unacceptably brittle against potential refactoring changes. – Jonathan Schneider Jan 14 '13 at 23:40
Agreed, any issues would be caught at runtime, in the consumer app. Ugh. – andrej_k Oct 16 '13 at 19:23

Agree, dont shoot the messenger, I did mention it was RoboGuice's own recommendation right? :) – Roberto Andrade Oct 16 '13 at 22:38
