Animation To Guide Us All 2nd Edition

At DevFest Seattle and Android TO I talked about how animations can greatly increase the UX of your app and make it more simple.

The source code for the project can be found here: https://github.com/marcospaulo/cinema_example

1. Animations to Guide Us All How animations can help guide your users +Marcos Damasceno @marcospaulosd
2. +Marcos Damasceno @marcospaulosd Google Developer Expert Android Android Engineer @ Mirego Droidcon Montreal and GDG Android Montreal Organizer Speaker (Droidcon NYC, London…) Brazilian
3. Outlines Evolution of Mobile Apps UX Complexities Meaningful Animations Activity Transitions Conclusion
4. A STORY!
5. I’m an engineer/developer/programmer
9. Complicated environment Demands better apps
10. Engineer UX/Design
11. The Evolution of Mobile Apps At the beginning of all times, Mobile Applications were there for simple uses.
12. The Evolution of Mobile Apps Big screens have brought way more possibilities But bad design strategies decrease UX quality
13. The UX/UI Dilema Unnecessary Buttons Lack of context Bad use of design strategies
14. The UX/UI Dilema Coding an app is not the hardest part anymore, but actually knowing where to put your elements, functionalities and even how to do the flow of your app is the real challenge.
15. Motion Design
16. Motion Design Where things come from, where do they go, what can I do. Motion Matters
17. Motion Design Where things come from GOOD BAD
18. Motion Design Where do they go
19. Motion Design What can I do
20. Drawables Overview We will see how we can take advantage of drawables so we can reduce the amount of resources in our application. Also we will see cases where a drawable could easily replace views, making our app more clean and faster. Objective
21. Motion Design Animations to the rescue Animations can help simplify your app and eliminate unnecessary tutorials or even buttons
22. Motion Design Just answer these 3 questions Where things come from Where do they go What can I do
23. Motion Design Your animations should make sense It should have a reason to exist
25. Activity Transitions
26. Activity Transitions Activity transitions in material design apps provide visual connections between different states through motion and transformations between common elements
27. Activity Transitions Enter Exit Shared Element How views in an activity enter the scene How views in an activity exit the scene How views shared between 2 activities transition
28. Default Activity Transition
29. Cool Activity Transition :)
30. Even Cooler Activity Transition :)
31. Provided Activity Transition Animations - Explode getWindow().setEnterTransition(new Explode()); getWindow().setExitTransition(new Explode());
32. - Slide getWindow().setEnterTransition(new Slide(Gravity.TOP)); getWindow().setExitTransition(new Slide(Gravity.Bottom)); Provided Activity Transition Animations
33. Animations should make sense Choreography should be used to show the elements of your screen to the user, guiding him so he can know what he can do
34. Cool Activity Transition :)

54. Activity Transitions are easy they said It will save you time they said
55. The problem /** @hide */
 @Override
 public void captureTransitioningViews(List<View> transitioningViews) {
 if (getVisibility() != View.VISIBLE) {
 return;
 }
 if (isTransitionGroup()) {
 transitioningViews.add(this);
 } else {
 int count = getChildCount();
 for (int i = 0; i < count; i++) {
 View child = getChildAt(i);
 child.captureTransitioningViews(transitioningViews);
 }
 }
 } Before the transition starts, the framework constructs the set of transitioning views by performing a recursive search on the Activity window’s (or Fragment’s) entire view hierarchy.

85. Activity Transitions - Easy to use once understand how it works - Limited customization due to TransitioGroup handling - Only available on Lollipop +
86. THINK LIKE AN ANIMATOR The way you write your xml layout will directly affect how your Activity Transition Animations will work.
