# angelauramc-openjdk-build 

**This branch is for OpenJDK 17 and 21.**

Based on [Java for Android](http://openjdk.java.net/projects/mobile/android.html) and [the PojavLauncher variant](https://github.com/PojavLauncherTeam/android-openjdk-build-multiarch)

## Building 

### Setup
#### Android
**Note:** We use Ubuntu 24.04 LTS to build our JDKs. Adapt these dependencies to your distribution, it should build fine.
- Install `autoconf`, `python3`, `python-is-python3`, `unzip`, `zip`, `systemtap-sdt-dev`, `libxtst-dev`, `libasound2-dev`, `libelf-dev`, `libfontconfig1-dev`, `libx11-dev`, `libxext-dev`, `libxrandr-dev`, `libxrender-dev`, `libxtst-dev`, `libxt-dev`.
- If building JDK 17, install `openjdk-17-jdk`. For 21, `openjdk-21-jdk`.
- Install Android NDK r27b.

#### iOS
- Install latest Xcode on your Mac.
- If building JDK 17, install JDK 17. For 21, install JDK 21.
