Some Transition Animations Not Work on Android 2.2/2.3

[Ming Zhe Huang]

Please use an Android Mobile Phone (2.2/2.3) to visit the test page: ​http://archive.dojotoolkit.org/nightly/checkout/dojox/mobile/tests/test_transition-animations2.html The following animations do not work.

Cover Cover (Reverse) Slide Vertical Slide Vertical (reverse) Cover Vertical Cover Vertical (reverse)

hi kami, what's the latest status on this? we're getting close to beta2

[Atsushi Ono]

We have been working on this issue. The root cause of this issue appears to be that a transition animation and a scroll animation of ScrollableView? occur at the same time. We have reached a workaround on Android 2.3, although which does not work on Android 2.2. We do further investigation on Android 2.2.

[Atsushi Ono]

We have also found a solution on Android 2.2. To dispatch mouse click events initiating transition animations in ScrollableView? with "setTimeout" function resolve this issue. We will commit it after regression tests.

I tried the mobile gallery. Some transition effects do NOT 100% work in "Transitions" demo: Cover, Cover(reverse), Slide Vertical, Slide Vertical(reverse). Please see the attached test case. They sometimes fail. It seems that the problem is related to the deep component hierarchy.

flip still isnt working on android in beta 2 - see test_transition-animations2.html

Yes, as far as I know, rotateY/rotateZ on webkit on android 2.2/2.3 are broken, thus animations that use rotateY/rotateZ (like flip) never work on such platforms. There's nothing we can do about it.

onoat, correct me if I am wrong.

(In [25734]) Fixes #13154 !strict. View#performTransition changes display/visibility styles a couple of times, reducing of them seems to mitigate the problem. The problem apparently comes from android animation's instability, so there's no logical explanation here. The revealv animation was too fast. Adjusted its duration.
