[FIXED] How to save object in memory for all activity\ies when application is alive, Android

Issue

I have an app, it uses Rxjava and Retrofit to retrieve data from backend.

after login, I will get a JSON file which includes User information (name, email, id, stripeId....). I will need to use User information when retrieving data from backend in other activities. Since there are many times I need to use the User information, saving it in Database or SharePreference may spend a lot of time.

Is there any way that I can save the data in the memory when the App is alive (not killed in the background)? Thanks first.

Solution

You can extend Application Class which is initiated on application startup. Check it here:
