* From [Boardwalk](https://github.com/zhuowei/Boardwalk)'s ashes here comes PojavLauncher!
* PojavLauncher is a launcher that allows you to play Minecraft: Java Edition on your Android device!
* It can run almost every version of Minecraft, allowing you to use .jar only installers to install modloaders such as [Forge](https://files.minecraftforge.net/) and [Fabric](http://fabricmc.net/), mods like [OptiFine](https://optifine.net) and [LabyMod](https://www.labymod.net/en), as well as hack clients like [Wurst](https://www.wurstclient.net/), and much more!
* For more details [check out our wiki](https://pojavlauncherteam.github.io/)
## Some notes to start with
- We do not have an official TikTok account. No one from the dev team makes TikTok videos.
- The official Twitter for PojavLauncher is [@PLaunchTeam](https://twitter.com/PLaunchTeam). Any others (most notably @PojavLauncher) are fake.

## Introduction
* PojavLauncher is a Minecraft: Java Edition launcher for Android and iOS based on [Boardwalk](https://github.com/zhuowei/Boardwalk).
* This launcher can launch almost all available Minecraft versions ranging from rd-132211 to 1.21 snapshots (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](https://github.com/PojavLauncherTeam/PojavLauncher_iOS).
## Getting PojavLauncher
You can get PojavLauncher via three methods:
1. You can get the prebuilt app from [stable releases](https://github.com/PojavLauncherTeam/PojavLauncher/releases) or [automatic builds](https://github.com/PojavLauncherTeam/PojavLauncher/actions).
2. You can get it from Google Play by clicking on this badge:
[](https://play.google.com/store/apps/details?id=net.kdt.pojavlaunch)
3. You can [build](#building) from source.
## Building
If you want to build from source code, follow the steps below.
### Java Runtime Environment (JRE)
- JRE for Android is [here](https://github.com/PojavLauncherTeam/openjdk-multiarch-jdk8u), and the build script is [here](https://github.com/PojavLauncherTeam/android-openjdk-build-multiarch).
- Follow build instruction on build script [README.md](https://github.com/PojavLauncherTeam/android-openjdk-build-multiarch/blob/buildjre8/README.md).
- You can also get [CI auto builds](https://github.com/PojavLauncherTeam/android-openjdk-build-multiarch/actions) if you are lazy or are failing to build it for some reason.
* Either get the `jre8-pojav` artifact from auto builds, or split all artifacts 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:
A file named `universal.tar.xz` with all platform-independent files
4 files named `bin-.tar.xz` with all platform-dependent files per-architecture
- Put these in the `assets/components/jre/` folder
- (If needed) update the Version file with the current date
### LWJGL
The build instructions for the custom LWJGL are available over the [LWJGL repository](https://github.com/PojavLauncherTeam/lwjgl3)
### The Launcher
- Because languages are auto-added by Crowdin, you need to run the language list generator before building. In the project 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 ~~or build using Android Studio~~.
* Build GLFW stub:
```
./gradlew :jre_lwjgl3glfw:build
```
* Build the launcher
```
./gradlew :app_pojavlauncher:assembleDebug
```
(Replace `gradlew` with `gradlew.bat` if you are building on Windows).
