Android T 远程动画显示流程（更新中）

序

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
在这里插入图片描述添加log
Slog.i("WindowManager","createAnimationLeash type = " + animationTypeToString(type) + " animatable = "+animatable, new Exception());

removeLeash
在这里插入图片描述添加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）：

冷启动

WindowManager: createAnimationLeash type = app_transition animatable = Task{d0b86 #77 type=standard A=10116:com.example.mysystemdialog}
WindowManager: createAnimationLeash type = app_transition animatable = Task{2c8eb49 #1 type=home}
WindowManager: createAnimationLeash type = window_animation animatable = WallpaperWindowToken{79ea104 token=android.os.Binder@30f6996}
WindowManager: removeLeash leash = Surface(name=Surface(name=Task=1)/@0x50de32e - animation-leash of app_transition)/@0x5e2271f
WindowManager: removeLeash leash = Surface(name=Surface(name=Task=77)/@0xeb831c3 - animation-leash of app_transition)/@0xebdcd79
WindowManager: removeLeash leash = Surface(name=Surface(name=WallpaperWindowToken{79ea104 token=android.os.Binder@30f6996})/@0xa32d428 - animation-leash of window_animation)/@0xd323396
WindowManager: createAnimationLeash type = starting_reveal animatable = Window{a65f40b u0 com.example.mysystemdialog/com.example.mysystemdialog.MainActivity}
WindowManager: createAnimationLeash type = window_animation animatable = Window{dad6bc2 u0 Splash Screen com.example.mysystemdialog}
WindowManager: removeLeash leash = Surface(name=Surface(name=a65f40b com.example.mysystemdialog/com.example.mysystemdialog.MainActivity)/@0xdbce2c1 - animation-leash of starting_reveal)/@0x6df31a7
WindowManager: removeLeash leash = Surface(name=Surface(name=dad6bc2 Splash Screen com.example.mysystemdialog)/@0x3868f87 - animation-leash of window_animation)/@0x9d22add

应用不在后台运行，从桌面点击一个应用冷启动，动画顺序如下：

动画窗口动画类型操作
mysystemdialog（Task）app_transition创建
home（桌面Task）app_transition创建
WallpaperWindowToken（壁纸）window_animation创建
home（桌面Task）app_transition移除
mysystemdialog（Task）app_transition移除
WallpaperWindowToken（壁纸）app_transition移除
MainActivity冷启动应用主界面（ActivityRecord）starting_reveal创建
mysystemdialog的冷启动窗口（Splash Screen）window_animation创建
MainActivity冷启动应用主界面（ActivityRecord）starting_reveal移除
mysystemdialog的冷启动窗口（Splash Screen）window_animation移除

热启动

WindowManager: createAnimationLeash type = app_transition animatable = Task{d0b86 #77 type=standard A=10116:com.example.mysystemdialog}
WindowManager: createAnimationLeash type = app_transition animatable = Task{2c8eb49 #1 type=home}
WindowManager: createAnimationLeash type = window_animation animatable = WallpaperWindowToken{79ea104 token=android.os.Binder@30f6996}
WindowManager: removeLeash leash = Surface(name=Surface(name=Task=1)/@0x50de32e - animation-leash of app_transition)/@0x6c5dc4f
WindowManager: removeLeash leash = Surface(name=Surface(name=Task=77)/@0xeb831c3 - animation-leash of app_transition)/@0x8775329
WindowManager: removeLeash leash = Surface(name=Surface(name=WallpaperWindowToken{79ea104 token=android.os.Binder@30f6996})/@0xa32d428 - animation-leash of window_animation)/@0x8534d86
WindowManager: createAnimationLeash type = window_animation animatable = Window{d22fcb2 u0 SnapshotStartingWindow for taskId=77}
WindowManager: removeLeash leash = Surface(name=Surface(name=d22fcb2 SnapshotStartingWindow for taskId=77)/@0xfcbebd0 - animation-leash of window_animation)/@0x3faeece

应用本身就在后台运行，从桌面热启动应用，动画顺序如下：

动画窗口动画类型操作
mysystemdialog（Task）app_transition创建
home（桌面Task）app_transition创建
WallpaperWindowToken（壁纸）window_animation创建
home（桌面Task）app_transition移除
mysystemdialog（Task）app_transition移除
WallpaperWindowToken（壁纸）app_transition移除
mysystemdialog的热启动窗口（SnapshotStartingWindow）window_animation创建
mysystemdialog的热启动窗口（SnapshotStartingWindow）window_animation移除

home回到桌面

WindowManager: createAnimationLeash type = app_transition animatable = Task{2c8eb49 #1 type=home}
WindowManager: createAnimationLeash type = app_transition animatable = Task{d0b86 #77 type=standard A=10116:com.example.mysystemdialog}
WindowManager: createAnimationLeash type = window_animation animatable = WallpaperWindowToken{79ea104 token=android.os.Binder@30f6996}
WindowManager: removeLeash leash = Surface(name=Surface(name=Task=77)/@0xeb831c3 - animation-leash of app_transition)/@0x77da703
WindowManager: removeLeash leash = Surface(name=Surface(name=Task=1)/@0x50de32e - animation-leash of app_transition)/@0x12ce9bd
WindowManager: removeLeash leash = Surface(name=Surface(name=WallpaperWindowToken{79ea104 token=android.os.Binder@30f6996})/@0xa32d428 - animation-leash of window_animation)/@0x5e69f0a

在应用界面，点击home键退回到桌面界面，动画顺序如下：

动画窗口动画类型操作
home（桌面Task）app_transition创建
mysystemdialog（Task）app_transition创建
WallpaperWindowToken（壁纸）window_animation创建
mysystemdialog（Task）app_transition移除
home（桌面Task）app_transition移除
WallpaperWindowToken（壁纸）window_animation移除

小结

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；移除动画时，从IRemoteAnimationFinishedCallback流程到removeLeash流程。
