Pre Installing Android Application

How to pre-install an Android application? Because I have a specific device, and I wanted to make my application pre-installed.

Solution 1:

I'm assuming you're talking about a rom here.

If you want the user to be able to delete the application you should put the .apk file in "/data/app" If you want to have the app behave like a system app (like e-mail or calendar) you can put the .apk in "/system/app"
