How to navigate to activity located in different module

Question

I am working on application which is divided by features into modules.

App structure looks like so:

• app (application)
  • MainActivity
  • MainApplication
• featureOne (module)
  • FirstActivity
• featureTwo (module)
  • SecondActivity

Feature modules cannot depend on each other, but I can edit them freely. My goal is to navigate from FirstActivity to SecondActivity.

I cannot use startActivity(Intent(com.example.featureTwo.SecondActivity)), because SecondActivity class is not visible to FirstActivity(different independent module).

Question is what is the proper way to navigate from FirstActivity to SecondActivity?

I was thinking about using:

• Broadcast - I would send broadcast from FristActivity and register broadcast receiver, in featureTwos manifest. From broadcastReceiver I would launch SecondActivity.
• Deep Links - Similar to the broadcastReceiver.
• Creating function in application class and an enum within app package containint activies I want to launch. I would call this function whenever I want to launch activity like so: launchActivityFromDifferentModule(EnumWithActivities.SecondActivity).

Which method should I use, which one I shouldn't and why?

Answer 1

have many approaches for lunching activity in another module

1. Reflection

   Props: easily navigate to another class without define class in the app module.

   Cons: reflection is running at runtime.

2. DeepLink

   Props: create a unique link for any item in another module like openFragmentA, addCreditToUserAccount, etc.

   Cons: not have a serious concern.

3. Broadcast

   Props: declare determined activity in the app module (if have nav module setup inside).

   Cons: need more time to change and define another module.

Conclusion

Deeplink is suitable for a dynamic feature (onDemand feature) Broadcast is suitable for a main feature, permanently feature Reflection is suitable when not confident for a feature like A/B test feature
