would you mind pasting the output of the build error?
The goal here is to use caffe2 as a prebuilt dependency. Try downloading caffe2 and running ./scripts/build_android.sh
@bwasti Here is the prompt FAILURE: Build failed with an exception.

I have tried ./scritps/build_android.sh and integrated by android.mk in my app, But it seems the same problem, the undefined reference 'atof' ... The only version that run well is the previous one who do the compile and build in gradle. I can't understand what happened. By the way, I use android 18.
Thanks for propose a caffe2 android demo, But it can't pass the build and compile step when this project passed to new verison. It always has a link problem. So I ask for the previous version which includes the build and compile step in android studio by source code, and I had tested it, it works. If it has a link or something to go to the old version, thank you.@bwasti
