InjektionException: No registered instance or factory for type com.brianegan.bansa.Store

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?

[brianegan]

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.

[brianegan]

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

[DavidMihola]

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.

[brianegan]

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!

[DavidMihola]

Great! I am looking forward to trying Bansa!

[brianegan]

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.
