c# - Xamarin Android: Recent Apps and Activities -

-



i've been developing first xamarin android app in c# few weeks. approach @ separating different aspects of app each other have multiple activities: 1 login 1 main menu 1 settings ...

while navigating through app noticed each activity opened shown under recent apps. counter started finishing current activity before launching new 1 using intent aswell overwriting onbackpressed in each activity control activity loaded next.

is bad design? how usual apps 1 know behave? never noticed app listed multiple times under recent apps feel wrong. state of art have 1 activity , handle fragments?

this question difficult answer, there advantages , drawbacks of both strategies.

in essence, people prefer use fragments nowadays multiple reasons:

  • activities more memory intensive,
  • it easier handle navigation stack using fragmentmanager
  • fragments adaptable both phone , tables
  • compared activities, fragments easier re-use
  • a fragment cannot exist on own, must part of activity
  • fragments although more complex implement compared activities

in end, strategy decide use. pointed out yourself, activities show in list of recent applications. won't case when using fragments.
