本地动画和远程动画区别是什么? 本地动画自给自足。对自身SurfaceControl矢量动画进行控制。 远程动画拿来吧你一个app A对另一个app B通过binder跨进程通信控制app B的SurfaceControl矢量动画。 无论是本地动画还是远程动画都仅仅只是对SurfaceControl动画图层控制而无法控制应用内部的View。 注矢量动画包含位移、放大、缩小、透明度、圆角等。
常见的远程动画就是桌面与应用交互。比如我们从桌面点击一个应用启动这个应用这个过程中会产生的动画就是远程动画。 我们从这个角度分析其动画显示过程。
显示过程分析
我们前面通过学习Android T 窗口动画本地动画显示流程发现无论什么类型动画都有其创建和移除的过程在SurfaceAnimator中createAnimationLeash和removeLeash添加log打印堆栈信息。 createAnimationLeash 添加log Slog.i(WindowManager,createAnimationLeash type animationTypeToString(type) animatable animatable, new Exception());
removeLeash 添加log Slog.i(WindowManager,removeLeash leash leash , new Exception());
我们看看下面几种启动的动画创建和移除的过程排除了insets类型的动画

从当前分析以及堆栈来看应用的启动窗口相关动画冷启动应用主界面starting_reveal、冷启动窗口Splash Screen、热启动窗口SnapshotStartingWindow均为本地动画其他的动画均为远程动画。
本地动画 窗口类型冷启动应用主界面starting_reveal、冷启动窗口Splash Screen、热启动窗口SnapshotStartingWindow。 代码逻辑创建动画时从applyAnimationLocked流程到createAnimationLeash移除动画时从LocalAnimationAdapter的Callback到removeLeash流程。 注starting_reveal类型动画比较特殊涉及到StartingWindow动画流程。 远程动画 窗口类型桌面Task、应用Task、壁纸。 代码逻辑创建动画时从handleAppTransitionReady流程到createAnimationLeash移除动画时从IRemoteAnimationFinishedCallback流程到removeLeash流程。
