Hi,

I just wanted to try your Bansa counter example (by the way, I have to chuckle every time I misread this as "Bansa counterexample") and it crashed with the following exception:

java.lang.RuntimeException: Unable to instantiate application com.brianegan.bansa.counter.Application: uy.kohesive.injekt.api.InjektionException: No registered instance or factory for type com.brianegan.bansa.Store<com.brianegan.bansa.counter.ApplicationState, com.brianegan.bansa.Action>

I haven't done much Kotlin and haven't used Injekt at all - could you tell me what I am doing wrong?

commented

Ah, very interesting problem! Is this on an Android 4.x device by chance? I've been developing against Lollipop+ Devices and hadn't tried out Injekt with 4.x devices just yet.

commented

Also "Bansa Counterexample" haha -- might need to change that one up :P

commented

4.x indeed. An LG G2 with Android 4.4.2, to be precise.

Unfortunately, I won't have access to any Android 5 devices before Tuesday to try Bansa on.

But maybe I have the time to look into Injekt and Android 4.

commented

Good catch! This is my first time using Injekt, was trying it out as an experiment. I've tried a couple other sample projects and saw similar errors. I'll find the root cause and fix it up for 4.x devices.

Thanks for the report, and sorry about the trouble!

commented

Great! I am looking forward to trying Bansa!

Hey, just as a heads up, I'm working with the author of the dependency Injection framework to figure out the 4.x issues: kohesive/injekt#33

In the meantime, I'll probably rip out this form of dependency injection in favor of 1) No injection (It's not necessary for a lot of these smaller apps). or 2) Replace it with dagger so it works everywhere.

Thanks again for reporting this bug!

As a heads up: Bansa works fine with Android 4.x once the dependency injection is removed.
