XPLATJ2

XPLATJ is a trial project aim to make a cross-platform layer to create application (This project is still in early stage.).

this repository is a fork from XPLATJ1(https://github.com/partic2/xplatj1), and gdx backend is dropped(*).

How to build

prerequire

C Compiler(GCC CLANG)

CMake

OpenJDK

Gradle

Android SDK

Android NDK

SDL2 Source

Python3(to run build script)

step1

cd $XPLATJ_SOURCE_ROOT
export ANDROID_NDK=AndroidNdkDir  #set Android ndk location
cp $SDL_SOURCE_ROOT $XPLATJ_SOURCE_ROOT/SDL  #copy SDL source

cd launcher

export CC=GCC
export CXX=G++

#you can create and custom build_config.txt refer to build_config_sample.txt.
python build.py

step2

You can find the native distrubution in ${XPLATJ_SOURCE_ROOT}/launcher/build/xplatj-native-release

For Android, You can find the distrubution in ${XPLATJ_SOURCE_ROOT}/launcher/build/xplatj-release.apk

Two backend

You can switch the backend by modify the config file "$RESOURCE_DIR/flat") The first word control the backend and can be one of webapp or sdl.

When use SDL backebd, xplatj compile "$RESOURCE_DIR/boot0.c" and load this file , then run the entry function _start(void *) Some symbol will added to the context. View launcher/SDLLoader.c for more detail.

On windows/linux target: RESOURCE_DIR=./res

On android target: RESOURCE_DIR=/sdcard/xplat

Why dropped gdx backend and switch to XPLATJ2

The dynamic module mechanism of Java/Android is not as convinient as some "script language", due to platform difference and type model. and it is impossible to upgrade Java on Android without os upgrade. but there are still possibility for gdx backend to reappear in future.
