excludeFromRecents不与taskAffinity工作 [英] excludeFromRecents doesn't work with taskAffinity

问题描述

比方说，我有两个活动的一个（主要活动）和B.我开始从A，B如下：

Let's say I have two activities A (the main activity) and B. I start B from A as follows:

    Intent i = new Intent(A.this, B.class);
    i.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
    startActivity(i);

我想我的应用程序已经在最近通话随时AND B只是一个入口在一个新的任务来启动。如果B有一个清单条目，如下所示，我做到这一点：

I want my app to have just one entry in the recents at any time AND B to be started at a new task. If B has a manifest entry as follows, I achieve that:

    <activity
        android:name="com.example.verysimpleactivity2.app.B"
        android:excludeFromRecents="true"
        android:label="B" ></activity>

不过，我也希望B有不同的taskAffinity比的主要活动，即：A。所以我改变了清单进入：

But I also want B to have a different taskAffinity than the main activity, i.e. A. So I change the manifest entry into:

    <activity
        android:name="com.example.verysimpleactivity2.app.B"
        android:excludeFromRecents="true"
        android:taskAffinity=""
        android:label="B" ></activity>

在这种情况下，如果B不在前台那么它不会在最近通话显示了，我只有一个（好！）但是，如果B是在前台和我preSS最近通话按钮，我看到A和B在那里。为什么显示在这种情况下的最近通话乙？如何确保我不会见B呢？

In this case, if B is not in the foreground then it does not show up in the recents and I only have A (good!) However, if B is in the foreground and I press recents button, I see both A and B there. Why is B shown in the recents in this case? How to make sure I don't see B at all?

推荐答案

显然，这是不可能实现我想要的（至少在奇巧）。

Apparently, it is impossible to achieve what I want (at least in KitKat).
