如何啓動android應用程序管理器

有誰知道android上的應用程序管理器的軟件包名稱。我有我想允許用戶直接從我的應用程序到應用程序管理器的方法：如何啓動android應用程序管理器

public void goToApplicationManager(){ 
     Intent startMain = this.getPackageManager().getLaunchIntentForPackage("com.android.settings.ManageApplications"); 

     startActivity(startMain); 
    }

而是拋出一個錯誤..我可以做com.android.settings，這將需要用戶進行設置，但我想將它們專門帶到應用程序管理器。我有錯誤的包名嗎？

我的錯誤：

你看着ACTION_MANAGE_APPLICATIONS_SETTINGS或ACTION_MANAGE_ALL_APPLICATIONS_SETTINGS？
