3.1.0

Added

• MvpQueueingBasePresenter: This Presenter has a method onceViewAttached(ViewAction) that internally queues all ViewAction if no view is attached to this presenter and executes all queued actions once a view is attached. If a view is attached, the ViewAction executes immediately. This class is useful in MVP powered apps with backstack navigation.

Changes

• MvpPresenter.detachView(boolean retainInstance) is now split in two methods:
  • detachView(): Was the same as detachView(retainInstance = true)
  • destroy(): Was the same as detachView(retainInstance = false)
    Please note that destroy() is called when the corresponding View is also destroyed permanently. For example, if FragmentA (View) has PresenterA. Once we push a new Fragment B (with Presenter B) on top of the stack, PresenterA.detachView() is called because View of FragmentA is destroyed temporarily.

Deprecations

• MvpPresenter.detachView(boolean retainInstance) is deprecated now. Use detachView() and destroy().
• MvpBasePresenter.getView() and MvpBasePresenter.isViewAttached() are deprecated. Use MvpBasePresenter.ifViewAttached(ViewAction), see #233
