## Setting up your development environment

In order to make changes to Gradle, you'll need:

* [Adoptium JDK](https://adoptium.net/temurin/archive/?version=17) (Java Development Kit) **version 17**. Fixed version is required to use [remote cache](#remote-build-cache).
* A text editor or IDE. We use and recommend [IntelliJ IDEA CE](http://www.jetbrains.com/idea/). IntelliJ Ultimate will also work. You'll need IntelliJ 2021.2.2 or newer.

Advanced Profiling
------------------

Android Studio’s Advanced Profiling feature rewrites OkHttp bytecode for instrumentation.
Unfortunately it crashes on OkHttp 4.x’s bytecode. Until [Google’s bug][advanced_profiling_bug] is
fixed you must disable advanced profiling in Android Studio.
