#### make failed to build some targets (01:41 (mm:ss)) ####
The app compiles and runs on android studio without any errors and warnings. As far as the ROM setup is concerned, I have added the app name in core.mk file at build/target/product. I have also added an Android.mk file in the main folder of the app. Any idea what could be the reason for these errors?
I was getting this error because my app had the precompiled java code that was created by Android studio. These errors were gone after I deleted those precompiled files from the java folder. The ROM compiler has a different build environment than the Android Studio or Eclipse environment.
