Recent Key UI -> Home screen (SystemShortCut 快捷方式的一种)
RecentTaskInfo -> WMS (其实是 ActivityManager 的内部静态类，继承自 TaskInfo。 可提供给App 使用 )
TaskInfo参考之前的介绍：https://www.jianshu.com/p/1aee1948ebf6
1. RecentTaskInfo 源码
frameworks/base/core/java/android/app/ActivityManager.java
package android.app;
@SystemService(Context.ACTIVITY_SERVICE)
public class ActivityManager {
/**
* Information you can retrieve about tasks that the user has most recently
* started or visited.
*/
public static class RecentTaskInfo extends TaskInfo implements Parcelable {...}
2. SystemShortCut 源码
packages/apps/Launcher3/src/com/android/launcher3/popup/SystemShortcut.java
package com.android.launcher3.popup;
/**
* Represents a system shortcut for a given app. The shortcut should have a label and icon, and an
* onClickListener that depends on the item that the shortcut services.
*
* Example system shortcuts, defined as inner classes, include Widgets and AppInfo.
* @param <T>
*/
public abstract class SystemShortcut<T extends Context & ActivityContext> extends ItemInfo
implements View.OnClickListener {
