Genymotion recently moved root access behind a paywall, making it a premium feature. However, if you're using Genymotion for Android development, testing, or educational purposes, having root access can be essential. Root access allows developers to access deeper functionality, test root-only features, and explore Android's internals without restrictions.
The good news is that with a bit of work, you can still enable root on a Genymotion emulator if you have access to its disk image and platform keys. This guide walks you through the process of adding a custom system app, RootToggle, which will allow you to switch root access on and off without needing Genymotion's paid root access feature.
This Gist details the steps to compile, sign, and install RootToggle as a system app in a Genymotion emulator by directly modifying the emulator's disk image IN LINUX (use a virtual machine on Windows to do that).
