如何获得在我们的应用程序在设备上运行的所有活动的列表。

How to get the list of all activities in our application that are running on the device.

例如：PDF生成和电子邮件活动包括：

For example: pdf generation and email activities included.

我可以检查与code的活动，如：

I can check for activities with the code like:

ActivityManager am = (ActivityManager) this.getSystemService(ACTIVITY_SERVICE);

     // get the info from the currently running task

     List< ActivityManager.RunningTaskInfo > taskInfo = am.getRunningTasks(1);

     Log.d("topActivity", "CURRENT Activity ::"

             + taskInfo.get(0).topActivity.getClassName());

     ComponentName componentInfo = taskInfo.get(0).topActivity;

   componentInfo.getPackageName();

然而，这将提供有关正在运行的活动是顶级活动的信息。

This will however give information about the running activity which is the top activity.

我的想法是白名单运行，使我的第三方应用程序可以运行它，而在设备上的活动。所以基本上，我需要在应用程序中所有正在运行的活动。

My idea is to whitelist the activities running so that my third party application can run it while on the device. So I basically need all of the running activities in the application.

推荐答案

这是方式来获得应用程序中所有正在运行的活动 -

This is the way to get all the running activities in the application -

try {
    ActivityInfo[] list = getPackageManager().getPackageInfo(getPackageName(),PackageManager.GET_ACTIVITIES).activities;

        for(int i = 0;i< list.length;i++)
        {
            System.out.println("List of running activities"+list[i].name);

        } 
    }

    catch (NameNotFoundException e1) {
        // TODO Auto-generated catch block
        e1.printStackTrace();
    }
