How to reduce tensorflow size for android?

I am trying to use TensorFlow in my android app. But the .so file is little bit larger than needed, is there a way to reduce libtensorflow_inference.so size?

I don't know how to reduce the size of the .so files, but there is a way to save huge amounts of space by making it possible to compress the TensorFlow model. See this excellent blog post by Pete Warden for more details.

In summary, you can use optimize_for_inference and quantize_graph to make it possible to compress a 87MB model to 24MB (you'll see this space saving when building the APK).

In addition to selective registration, you can try passing -c opt to bazel. For me this takes the uncompressed .so size from 24mb -> 13mb, and compressed from 5.5mb -> 4.4mb.

There's no good guide to doing this yet, but you can start by removing unneeded ops using the print_selective_registration_header script: https://github.com/tensorflow/tensorflow/blob/master/tensorflow/python/tools/print_selective_registration_header.py

This needs to be documented more extensively.

You can try to divide your apk to reduce apk size. Check this.
