I want to open last started activity by tapping on the notification in status bar. Suppose I start an Activity A (main activity of my app), this activity sends a notification to notification status bar. activity A also opens an activity B and B opens another activity C. From C i press home button. Now i want to go again to my app so from notification bar i tap on notification (which was sent by A). Here the notification should start activity C because it was last opened.

推荐答案

几天就回来我得到了我的问题非常非常简单的解决方案。而不是通过 recentTasks 迭代，并把我们的任务，然后得到的 baseIntent 通过它，我们可以做简单的事情，如下所示：

Few days back I got very very simple solution for my problem. Instead of iterating through recentTasks and getting our task and then getting baseIntent through it, we can do simple thing as follows:

Intent notificationIntent = new Intent(context, MainActivity.class);
notificationIntent.addCategory(Intent.CATEGORY_LAUNCHER);
notificationIntent.setAction(Intent.ACTION_MAIN);

baseIntent 包含相同的参数上面意图有。对因此而不是 baseIntent 从 recentTasks 霎那，这是相当不错的使用上面code。

baseIntent contains the same parameters as above Intent has. Hence instead of grabbing baseIntent from recentTasks, it's quite good to use above code.

本 notificationIntent 将被传递给 pendingIntent 继续使用。

This notificationIntent will then be passed to pendingIntent for further use.

提供： MainActivity 是，当我们推出我们的应用程序和第一个活动在AndroidManifest.xml中必须包含 IntentFilters 的 CATEGORY_LAUNCHER 和 ACTION_MAIN 。

Provided: MainActivity is the very first activity when we launch our app and in AndroidManifest.xml it must contain IntentFilters of CATEGORY_LAUNCHER and ACTION_MAIN.
