How to add a new App in an Android build?

I have implemented a small application in Android and I want to add it in my own customised build. I included it und开发者_C百科er /packages/apps. However, when I build the image I can't find the package in my system, despite the fact that others such as the Camera and other apps exist.

The Android.mk file is OK but it looks like I'm missing somewhere in a make file or a script where to compile my own app and copy it into the system apps.

Could anyone provide me any hint?

You should add the app's folder path to one of the .mk files. I dont remember the mk file's name right now. But you can search in the source for "*.mk" . Search under frameworks too. Check core.mk.
