Good news: you don't need to port zlib to Android, or use NDK to build it. The GitHub project has no value except educational sample.

Android NDK provides prebuilt libz.so and libz.a, and you should look up the standard manual to find the methods you need.

How do you use z library on android devices? I have iOS and I usually download epub files. I have told a few friends who have android devices and they tell me that they’re having trouble either with the z library app, or don’t know where to download the books. Please advise. I am curious. 👍🏽
I just use ZLibrary through the web like normal. I didn't know there was an app but they shouldn't need it. More on reddit.com
