Optimize library size with libsigner.so

[G00fY2]

Our release APK has a size of roughly 11 MB. The libsigner.so (uncompressed) alone is about 950 KB (for arm64-v8a). So the native library from Adjust Signature SDK causes a significant amount of the app size.

We can not evaluate how much effort you already put into optimizing binary size. Maybe there is still some room for improvement, like e.g. these technics: Android NDK: How to Reduce Binaries Size – The Algolia Blog
