Rosie incompatible with android.arch.lifecycle ¿? #94

Closed rubdottocom closed 6 years ago

rubdottocom commented 6 years ago

Hi I'm trying to implement a Lifecycle observer using android arch components and it crashes, seems the cause is RosieApplication, android.arch is unable to get ApplicationContext, so crash because is null.

 java.lang.RuntimeException: Unable to get provider android.arch.lifecycle.ProcessLifecycleOwnerInitializer: java.lang.NullPointerException: Attempt to invoke virtual method 'void android.app.Application.registerActivityLifecycleCallbacks(android.app.Application$ActivityLifecycleCallbacks)' on a null object reference

Do you know how can I integrate both parts?

pedrovgs commented 6 years ago

Hi @rubdottocom the current implementation of the framework is not related to the architecture components. Without taking a look at the code I can't see where the issue is. Could you upload an example project reproducing the crash?

rubdottocom commented 6 years ago

RosieTest.zip

I isolated a base Rosie project and seems to work, so should be a problem with my legacy project... I'll continue to investigate.

Thanks

Closing the issue then until we find a better clue about what's going on. Thanks for the example project 😺
