Introduction

PojavLauncher is a Minecraft: Java Edition launcher for Android and iOS based on Boardwalk. This launcher can launch almost all available Minecraft versions (from rd-132211 to 21w08b (1.17) snapshot, including Combat Test versions). Modding via Forge and Fabric are also supported. This repository contains source code for Android. For iOS/iPadOS, check out PojavLauncher_iOS.

Building

To get started, you can just get prebuilt app from stable release or automatic builds. If you want to build after launcher code changes, follow steps below.

Will be moved to BUILDING.md

Java Runtime Environment (JRE)

JRE for Android is here, also the build script here.
Follow build instruction on build script README.md.
You can also get CI auto builds.
Either get jre8-pojav artifact from auto builds, or do splitting by yourself:
- Get JREs for all of 4 supported architectures (arm, arm64, x86, x86_64)
- Split JRE into parts:
Platform-independent: .jar files, libraries, configs, etc...
Platform-dependent: .so files, etc...
- Create:
file named universal.tar.xz with all platform-independent files
4 files named bin-<arch>.tar.xz with all platform-dependent files per-architecture
- Put these in assets/components/jre/ folder
- (If needed) update the Version file with the current date

LWJGL

Coming soon

The Launcher

Because languages are auto added by Crowdin, so need to run language list generator before building. In this directory, run:

# On Linux, Mac OS:
chmod +x scripts/languagelist_updater.sh
bash scripts/languagelist_updater.sh

# On Windows:
scripts\languagelist_updater.bat

Then, run these commands ~~build use Android Studio~~.

# Build GLFW stub
./gradlew :jre_lwjgl3glfw:build
# mkdir app_pojavlauncher/src/main/assets/components/internal_libs
rm app_pojavlauncher/src/main/assets/components/lwjgl3/lwjgl-glfw-classes.jar
cp jre_lwjgl3glfw/build/libs/jre_lwjgl3glfw-3.2.3.jar app_pojavlauncher/src/main/assets/components/lwjgl3/lwjgl-glfw-classes.jar
        
# Build the launcher
./gradlew :app_pojavlauncher:assembleDebug

(Replace gradlew to gradlew.bat if you are building on Windows).

Current status

Known Issues

Minecraft 21w10a or newer are currently not yet supported due to the new GLSL usage.
In 1.16 and up spawn eggs banners are white (you can fix this by switching renderer to gl4es 1.1.5, only works on 1.16 and up, do not use under this version)
Controller mods aren't working
Random crashes could happen very often on Android 5.x during game load or join world.
With big modpacks textures could be messed up
If you're using gl4es 1.1.5 on 1.16 and lower texture will bug out when hit a mob
probably more, that's why we have a bug tracker ;)
