Vim4 not creating apk

1.I am trying to add new app in package which require to generate new apk at the time build.
2.I have added new app in package/app/ folder where every priv-app is present but it’s not generating apk which require service and framework.
3. when we keep that time it’s generating apk but if i put android.bp file it is not generating apk

in the you will have to add the apps that you want to have compiled with the rom.
