我已阅读,http://developer.android.com/guide/components/tasks-and-back-stack.html并且我查找了FLAG_ACTIVITY_CLEAR_WHEN_TASK_RESET的文档,但我仍然不明白为什么Google的员工决定将其包含在他们关于共享的博客文章中.

这是他们的代码片段:
Intent intent=new Intent(android.content.Intent.ACTION_SEND); intent.setType("text/plain"); intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_WHEN_TASK_RESET); // Add data to the intent,the receiving app will decide what to do with it. intent.putExtra(Intent.EXTRA_SUBJECT,“Some Subject Line”); intent.putExtra(Intent.EXTRA_TEXT,“Body of the message,woot!”);
文件说:
If set,this marks a point in the task's activity stack that should be cleared when the task is reset...
我仍然不确定这面旗帜.我不确定我是否可以考虑将其包含在我的share()方法中,但如果Google在博客文章中使用它,那么我确信他们知道这种情况会发挥作用.提前致谢.
