How to use

you can download example and study how to use

1. init lua

init lua file only once after start app

private void initLua(){
        mLuaState = LuaStateFactory.newLuaState();
        mLuaState.openLibs();
        //push Log object to lua, in lua using like: Log:i(TAG, "this log can show in AS logcat window")
        try {
            mLuaState.pushObjectValue(Log.class);
            mLuaState.setGlobal("Log");
        } catch (LuaException e1) {
            // TODO Auto-generated catch block
            e1.printStackTrace();
        }
    }

2. add lua file to raw

app/src/main/res/raw/luafile.lua

function GetVersion(info, intvalue)
    Log:i("LuaLog", info..intvalue)
    print('this log')
    return 1
end

3. invoke lua function

private void executeLuaFile()
    {
            mLuaState.getGlobal("GetVersion");
            mLuaState.pushString("reload lua test");// input params
            mLuaState.pushNumber(10);
            mLuaState.call(2, 1);//2 input, 1 output
            String result = mLuaState.toString(-1);
            if (result == null){
                System.out.println("GetVersion return empty value");
            }else {
                System.out.println("GetVersion return value"+result);
            }
    }
