how to replace a RoboGuice default binding?

[kevin wu]

I want to inject a ContentResolver into a POJO class.  In my AbstractModule sublcass, I've created a provider that simply gets the content resolver from my application's context.  I've also bound ContentResolver.class to the provider.

When I start my application, however, RoboGuice says that "A binding to android.content.ContentResolver was already configured at roboguice.config.DefaultRoboModule.configure(DefaultRoboModule.java:140)".

How do I resolve this?

Actually it looks like there's a placeholder for this how-to on RoboGuice's github, called "Remove or replace RoboGuice's default bindings"...


Alternatively, is there a way to use a RoboGuice-provided injection in a POJO class?  I suppose I'd like to know both :)

Take a look at Modules.override.  This should get you started: http://stackoverflow.com/a/531110

Cool thanks.

I wasn't entirely sure how to use it.  I thought I had to override the DefaultRoboModule.  I ended up creating a separate module just for my ContentResolver override; then in my Application subclass constructor, I put "Modules.override( new MyGuiceBindings() ).with( new ContentResolverBindingOverride() );".  Hopefully I am not committing any weird faux pas but it seems to work.  Thank you!

That's about right.  Just make sure you also include an instance of DefaultRoboModule in your modules list, otherwise you won't get any roboguice bindings at all.
