How to close another app in Android?

Question

I have been developing an app, and I need to close another app in my code. Does anyone know any api to call to close an app?

BTW: my app will be pre-installed.

If both applications are yours, you can use AIDL for inter-process communication to send a message telling the other application to close. See http://developer.android.com/guide/developing/tools/aidl.html.
