@Inject for findFragmentById?

[dsvensson]

Not sure if it's possible, but it feels like something that would be nice to deal with an @InjectSomething tag. Perhaps with supportFragmentManager vs fragmentManager distinction.

Currently do this in my onCreate:

frag = supportFragmentManager.findFragmentById(R.id.frag_something) as SomeFragment

I cant understand what you want to get. Can you please describe more in detail how it should work? You can post a complete class with your implementation and some comments in it to help us understand.
P.S. dont use 'as' operator too much, it will decrease performance.
Thanks.

Hi. If I'm not mistaken what you want is to be able to inject a fragment from XML:

<fragment android:id="@+id/myFragment" class="...">

In the same way we do it for views. While I think this could be a good thing, I'm not sure it should be done in an annotation way, as it isn't a widely used feature. I thought about using a DSL method, but it doesn't make it less verbose:

fragment = (MyFragment) activity.findFragment(R.id.myFragment)

I don't know. What do you think, @eugene-kamenev?

@Arasthel I think @dsvensson wants to define an additional parameter in annotation to use supportFragmentManager or fragmentManager am I wrong? :) just cant understand the goal

[dsvensson]

@SomeAnnotationCompatOrSupportOrSomething(R.id.frag_something) 
SomeFragment foo

Instead of what I wrote above

It could be done using just an annotation, as the AST transform could check if the activity/fragment is normal or compat. What I'm not really sure about is if it's worth the trouble of making the new transformation...
