活动在被销毁时是否保存其意图？

Question

想象一下，在用户打开另一个活动，然后再打开另一个活动等等之后，以意图启动活动的情况。此刻，由于缺乏RAM，第一个活动被破坏。用户导航回第一个活动后，第一个活动是否可以访问其初始意图？是否存在严格确定的行为？

Answer 1

从Android source获取的一些评论摘要：

/**     
     * Information you can retrieve about a particular task that is currently
     * "running" in the system.  Note that a running task does not mean the
     * given task actually has a process it is actively running in; it simply
     * means that the user has gone to it and never closed it, but currently
     * the system may have killed its process and is only holding on to its
     * last state in order to restart it when the user returns.
     */
    public static class RunningTaskInfo ...

请注意最后一句话： ...仅保留其最后状态，以便在用户返回时重新启动

         /**
         * The original Intent used to launch the task.  You can use this
         * Intent to re-launch the task (if it is no longer running) or bring
         * the current task to the front.
         */
         public Intent baseIntent;

从这一点可以看出，Android将保留原始的Intent以重新启动Activity，就像它从未被销毁一样。
