PojavLauncher

• From 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 and Fabric, mods like OptiFine and LabyMod, as well as hack clients like Wurst, and much more!

• For more details check out our wiki

  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. Any others (most notably @PojavLauncher) are fake.

Introduction

• PojavLauncher is a Minecraft: Java Edition launcher for Android and iOS based on 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.

Getting PojavLauncher

You can get PojavLauncher via three methods:

1. You can get the prebuilt app from stable releases or automatic builds.

2. You can get it from Google Play by clicking on this badge:

3. You can build from source.

   Building

   If you want to build from source code, follow the steps below.

   Java Runtime Environment (JRE)

   • JRE for Android is here, and the build script is here.
   • Follow build instruction on build script README.md.
   • You can also get CI auto builds 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-<arch>.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

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).

• Probably more, that's why we have a bug tracker ;)
