Example of Android project showing integration with Kotlin and Dagger 2

kotlin-dagger-example

This project demonstrate how to setup an Android Project with Kotlin and Dagger 2.

It's based on Dagger 2 example

##Known issues/limitations

When lateinit modifier is used, your variable cannot be used in init{} block. It will not compile. So in that case I suggest to move code from that block into a separate function and then call that function from init{} block.

##More than Dagger

This sample project includes some more dependencies which are very usefull. It's like a base setup for almost every project using Kotlin. So you will find there Anko libraries. You can uncomment Anko's DSL libraries if you need them. There is also a set of Rx dependencies. Rx works really great with Kotlin. At last but not least there my favourite networking dependencies from Square.

kotlin-dagger-example's Issues

Move all classes to Kotlin

Is it already possible to move all the code to Kotlin?

Here is a sample from JetBrains https://github.com/JetBrains/kotlin-examples/tree/master/gradle/kotlin-dagger and only one class is in java. That class uses code that should be generated by Dagger. Unfortunately if I rewrite it to Kotlin then Dagger is not generating anything.
According to this blog post http://blog.jetbrains.com/kotlin/2015/06/better-annotation-processing-supporting-stubs-in-kapt/ it should work now. Am I missing something?

I have tried to use 0.1-SNAPSHOT version of Kotlin as well as the newest 1.0 beta and result is the same.

Error when upgrading to Kotlin 1.0.0-beta-1103

Hi! I found this project very helpful to see how to set up kotlin with dagger! But when I tried to use the same method in my app, it didn't work. I realized that it is because I was using a newer version of Kotlin (version 1.0.0-beta-1103).

If you try updating the Kotlin version in this repo, you will get an error like this:
java.lang.NoSuchMethodError: No virtual method provideLocationManager$app_compileDebugKotlin()Landroid/location/LocationManager; in class Lorg/loop/example/AndroidModule;

Unfortunately, I don't know any solution for this problem. Do you have any ideas?

Can't inject Kotlin classes

Hello,

I've cloned your project and made some changes to see if I can introduce Dagger in my project, I cannot seem to find the way to inject Kotlin classes, and this example doesn't show that. I just inject a Java class..

The dagger generated classes doesn't seem to be able to find the Kotlin class and failed to compile..

I have this code in my activity:

@Inject
 lateinit var presenter: LoginPresenter

And this is the LoginPresenter:

class LoginPresenter : BasePresenter<LoginView> {

    @Inject constructor() {

    }

   ....
}

and it throws the following error

any ideas?

No Dagger 2 generated classes for androidTest (question)

Hey Damian, thanks for a great example.

Have you tried having Components in androidTest folder? It seems that Dagger2 doesn't generate its files for this setup. People solve this problem by using Android-apt plugin when using Java. Do you know anything about how to fix it in pure "Kotlin's way"? Thanks a lot.

[Question] Annotation Processing

There were rumors, that annotation processing doesn't work in Kotlin. But I see, that your example perfectly works. How is it possible?

NotNull

Is there any reason you don't use Delegates.notNull()?
