Dilemma: when to use Fragments vs Activities:

Question

I know that Activities are designed to represent a single screen of my application, while Fragments are designed to be reusable UI layouts with log

Answer 1

Don't forget that an activity is application's block/component which can be shared and started through Intent! So each activity in your application should solve only one kind of task. If you have only one task in your application then I think you need only one activity and many fragments if needed. Of course you can reuse fragments in future activities which solve another tasks. This approach will be clear and logical separation of tasks. And you no need to maintain one activity with different intent filter parameters for different sets of fragments. You define tasks at the design stage of the development process based on requirements.
