當它被銷燬時，活動會保存它的意圖嗎？

Question

想象一下，一種活動是以意向開始的，然後是用戶打開另一個活動，然後是另一個活動，等等。一時之間，由於缺乏內存，第一項活動將被破壞。用戶導航到第一個活動後，第一個活動是否可以訪問其初始意圖？有沒有嚴格的決定行爲？

Answer 1

從Android source採取了一些意見摘錄：

/**  
    * 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 ... 

注意最後一條語句：......只有堅持自己的最後的狀態，以便當用戶返回

  /** 
     * 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; 

重新啓動它

從中可以明顯看出，Android會堅持原來的Intent來重新啓動Activity，就好像它從未被銷燬一樣。
