[bykim555]

OS: Ubuntu 18.04 64bit LTS
Anaconda3-2019.03-Linux-x86_64
conda env used, Python: 3.6.8

git clone --recursive https://github.com/apache/incubator-mxnet.git
Tried to build version mxnet1.8.0.rc2
ci/build.py -p android_armv7. And build success.

But libmxnet.so(1.03GB) size is very big.

How to reduce libmxnet.so file size.

ci/build.py -p android_armv7 is not optimized for size. You should be able to reduce the size by adding -DCMAKE_BUILD_TYPE=Release option to the cmake call in ci/docker/runtime_functions.sh. You can also manually run strip --strip-unneeded libmxnet.so after the build.

Finally, if you only need to support a known set of networks / operations, you can delete unneeded operators in src/operator before the build.
