Android project with different modules(sharedPreferences)

Question

Does anyone know if android supports sharing the same sharedpreference across multiple Android Modules compiled in one project?

i have two shared preferences and currently when i try to access some data from a shared prefence outside of the current module, it doesnt work and creates a new sharedPrefence instead

example

Module one:

 mSharedPreferences = context.getSharedPreferences(
                "pref", Context.MODE_PRIVATE);

Module Two:

 mSharedPreferences = context.getSharedPreferences(
                "pref", Context.MODE_PRIVATE);

It creates two preference file instead of one where both modules can share the data

Answer 1

You can create a common :core module and add all your dependencies in that module.

Implement :core module in all your other modules.

Place you PrefHelpers class in :core module to access them from any module or you could configure sharedpreference using common package name can be obtained using BuildConfig.APPLICATION_ID.

 mSharedPreferences = context.getSharedPreferences(
                "pref", Context.MODE_PRIVATE);

can be replaced with

mSharedPreferences = context.getSharedPreferences(
                BuildConfig.APPLICATION_ID, Context.MODE_PRIVATE);

You can use the mode as Context.MODE_PRIVATE itself.

Make sure your BuildConfig is from your :core module.
