Availability For JAVA

[BismeetSingh]

Can this be ported to java. Seems better than the dagger hanging over my head.

Hello,

the interest of Koin is in its ease of use. Check the gists where I put Koin for a Java app:

I have used it in java. But injection was not done by java code. I have implemented base Kotlin class that I extended in java. Kotlin class was doing the injection and I could use it in java code. It looked like this:

class InjectClass {
  val presenter: Presenter by inject()
}

and then I have extended this class by java:

class InjextExtension extends InjectClass {
    public void fun() {
     ///this is how we access our dependency in java
      getPresenter();
   }
}

Here there are some utility functions to inject koin components and properties in java.
Basically this utility functions remove the reified types and replace them for java class.

Check it out:

@fredy-mederos looks like a very good solution. Could you also provide a snippet that shows how injection looks on java site?

[fredy-mederos]

Example in java:

MyManager myManager = KoinJavaUtils.get(MyManager.class);

You can use it in attributes and you can also use the function KoinJavaUtils.inject to get a Lazy object.

I wrote those utility functions to migrate from dagger2 some Android java activities that I can't convert to kotlin and it works good!

Good job @fredy-mederos! Could be a good contribution and blog post about it 👍

Thanks!
I'll create some test cases and include them all in the koin-core via PR
It is a good idea the blog post thing... I'll prepare a draft ;)

I close the issue here to continue on PR. Thanks
