What is the package name for “Task Manager” in Android to launch this activity?

问题

I want to launch Task Manager using Intent from my application. What is the package name for the Task Manager? I.e.,

startActivity(new Intent("android.intent.action.<task_manager_package_name>"))

Use this snippet to get package name of task manager

   apps=getPackageManager().getInstalledPackages(PackageManager.GET_META_DATA|PackageManager.GET_PERMISSIONS|PackageManager.GET_PROVIDERS); // gets all app details on phone

String packagename = new String(); 

  for(int index=0;index<apps.size();index++)
    {
        PackageInfo temp = apps.get(index);     //Iterate through the apps till you get task manager
        if(temp.applicationInfo.loadLabel(getPackageManager()).toString().equals("Task Manager")))
        {

          packagename = temp.packageName; //To get package name
          break;
        }

    } 

Then the string packagename will have the packagename of task manager
