What's the best way to check for permissions at runtime using MVP architecture?

Question

I\'m developing an android app in which I have to ask for permissions at runtime. I\'m wondering about the best way to implement that using Model-View-Presenter architecture.

Answer 1

What I would do is:

The view will implement:

public Activity getViewActivity();

The presenter will implement:

public void requestPermissions();
public void onPermissionsResult();

Inside requestPermissions, the presenter will do: getViewActivity().checkSelfPermission; getViewActivity.requestPermissions(); etc.

The view will call inside the onRequestPermissionsResult callback to presenter.onPermissionsResult();

With this all the logic will be implemented inside the presenter.

In my opinion, your presenter is decoupled: it won't depend on any view implementation (it will only depend on the view interface).

"I've heard that keeping your presenter free from Android code is good for testing." I don't understand this part. If the code is good, it can be tested without any problem.
