I am compiling using mmm /root/android/system/packages/apps/Contacts/

My doubt is when i recently rebooted my machine the output directory of the installed app is changed from OldPath : /root/android/system/out/target/product/vision/system/app to NewPath : /root/android/system/out/target/product/generic/system/app

all my other apps are present in the old path and when i install the contacts.apk from old path it installs properly and after i rebooted my machine and when i try to install from the new path where it is built, it gives me the following error. I don't understand what enviroment issue could that be? Could any one suggest me what can be done.

adb push Contacts.apk /system/app/Contacts.apk

You forgot to lunch before building. That's why it's building in out/target/product/generic instead of out/target/product/vision. It looks like your generic build is set up to build odexed apks, which is why there is no classes.dex inside the apk.

. build/envsetup.sh
lunch vision-userdebug # or -eng or -user
mmm packages/apps/Contacts
