我找到了一种在Android上使用LuaJ的方法！:-)

关键是直接使用LuaJ API，而不是通过。由于没有教程，所以要弄清楚这有点棘手，所以这里有一个之前和之后，这样其他人就不必通过选择LuaJ源代码和JavaDoc。我真的希望这能帮助某人，因为它让我发疯！javax.script

注意：“秘密游戏”不是我游戏的实际名称;-）

后：

package secretgame.scripting;

import java.io.ByteArrayInputStream;
import java.io.IOException;
import java.io.InputStream;
import java.util.ArrayList;

import org.luaj.vm2.LuaClosure;
import org.luaj.vm2.LuaTable;
import org.luaj.vm2.LuaValue;
import org.luaj.vm2.Prototype;
import org.luaj.vm2.compiler.LuaC;
import org.luaj.vm2.lib.jse.CoerceJavaToLua;
import org.luaj.vm2.lib.jse.JsePlatform;

import secretgame.SecretGameException;
import secretgame.events.EventArgs;
import secretgame.levels.Level;

public class DirectLuaj implements Lua
{
  private final Level level;
  private final ScriptTools scriptTools;
  private final ScriptEvents scriptEvents;
  private int nextId = 0;
  private ArrayList<LuaClosure> scripts = new ArrayList<LuaClosure>();

  public DirectLuaj(Level level, ScriptTools scriptTools,
      ScriptEvents scriptEvents)
  {
    this.level = level;
    this.scriptTools = scriptTools;
    this.scriptEvents = scriptEvents;
  }

  @Override
  public int add(String scriptText) throws SecretGameException
  {
    try {
      InputStream input = new ByteArrayInputStream(scriptText.getBytes());
      Prototype p = LuaC.compile(input, "script");
      LuaValue g = JsePlatform.standardGlobals();
      LuaClosure c = new LuaClosure(p, g);
      scripts.add(c);
    }
    catch (IOException e) {
      throw new SecretGameException("compile failed", e);
    }

    return nextId++;
  }

  @Override
  public void run(int id, EventArgs args) throws SecretGameException
  {
    LuaClosure script = scripts.get(id);

    LuaTable bindings = new LuaTable();

    bindings.set("java", toLua(scriptTools));
    bindings.set("level", toLua(level));
    bindings.set("args", toLua(args));
    bindings.set("events", toLua(scriptEvents));

    script.setfenv(bindings);

    script.call();
  }

  private LuaValue toLua(Object javaValue) {
    return javaValue == null? LuaValue.NIL:
            javaValue instanceof LuaValue? (LuaValue) javaValue:
            CoerceJavaToLua.coerce(javaValue);
  }
}

以前：

package secretgame.scripting;

import java.util.ArrayList;

import javax.script.Bindings;
import javax.script.Compilable;
import javax.script.CompiledScript;
import javax.script.ScriptEngine;
import javax.script.ScriptEngineManager;
import javax.script.ScriptException;

import secretgame.SecretGameException;
import secretgame.events.EventArgs;
import secretgame.levels.Level;

// sadly this won't work on Android because there's no such thing
// as javax.script in Dalvik ... dumb Android java :|
public class JavaxScriptingLua implements Lua
{
  private ScriptEngine scriptEngine;
  private final Level level;
  private final ScriptTools scriptTools;
  private final ScriptEvents scriptEvents;
  private int nextId = 0;
  private ArrayList<CompiledScript> scripts = new ArrayList<CompiledScript>();

  public JavaxScriptingLua(Level level, ScriptTools scriptTools, ScriptEvents scriptEvents)
  {
    this.level = level;
    this.scriptTools = scriptTools;
    this.scriptEvents = scriptEvents;

    ScriptEngineManager sem = new ScriptEngineManager();
    scriptEngine = sem.getEngineByExtension(".lua");
  }

  public int add(String scriptText) throws SecretGameException
  {
    try {
      CompiledScript script = ((Compilable)scriptEngine).compile(scriptText);
      scripts.add(script);
    }
    catch (ScriptException e) {
      throw new SecretGameException("could not compile lua.", e);
    }

    return nextId++;
  }

  public void run(int id, EventArgs args) throws SecretGameException
  {    
    Bindings bindings = scriptEngine.createBindings();

    bindings.put("java", scriptTools);
    bindings.put("level", level);
    bindings.put("args", args);
    bindings.put("events", scriptEvents);

    try {
      scripts.get(id).eval(bindings);
    }
    catch (ScriptException e) {
      throw new SecretGameException("could not run script.", e);
    }
  }
}

除了LuaJ，你还可以（也可以）使用LuaJava和Lua一起使用NdK为Android编译。这允许Lua完全访问Java提供的任何内容。请看一下此示例，了解如何开始使用。

Lua 5.1.4 + LuaJava编译在目录（单个文件）中提供，如果你不想摆弄NDK，但无论如何它相对容易设置。libslibluajava.so
