how to communicate in multi module dynamice feature Application

Question

I have project structure like

app:

InstantApp:

library:

dynamic-feature1:

dynamic-feature2:

dynamic-feature3:

Now there is some dependency between dynamic-feature1 and dynamic-feature2. Now if i add it as dependency in dynamic-feature2 build.gradle then it will cause cyclic dependency. Above is just one example there are many other cases too. How to handle such dependency conflicts properly or any suggestion?

Answer 1

Communicate from the main app module to a dynamic feature module

You can do this by reflection in Java. Make sure your class and method names are not obfuscated in the dynamic modules.

Get a Fragment/Activity or other class from module:

method.invoke(objectYouWantToInvokeTheMethodOn);

Get a method from your class:

 Method method = class.getMethod("GenerateQuestion");

Invoke the method:

 method.invoke(objectYouWantToInvokeTheMethodOn);

Communicate from dynamic feature module to main module

To get a parent activity of a dynamic feature module's fragment you can do:

 @Override public void onAttach(Context context) { super.onAttach(context); activity = (Activity) context; }

Then you can call a method on that activity.
