我有一个活动X中，已经进入一个有效的凭证后才能访问。

I have an Activity X which is only accessible after you've entered a valid credential.

如何从调用startActivity，意图指向于X prevent其他应用程序？

How can I prevent other apps from calling startActivity with an Intent pointing to X ?

例如

Intent intent = new Intent( this, ActivityX.class );
startActivity( intent );

基本上我不想活动X要出口到任何应用，除了我的应用程序。

Basically I don't want Activity X to be exported to any apps except my app.
