我正在开发一个使用Lua脚本的
Java中的
Android游戏.要执行这些脚本,我使用LuaJ与Java的ScriptEngine类.例如…
ScriptEngineManager sem = new ScriptEngineManager();
scriptEngine = sem.getEngineByExtension(".lua");
script = ((Compilable)scriptEngine).compile("some lua here");
然而,这显然不是在Android上支持的(与android没有完整的JVM有关,我在某处阅读).有没有办法在Android上使用Lua脚本？也许有一个LuaJ的选择？也许有一种使用LuaJ直接编译和执行Lua脚本的方法(虽然我看不到如何).
FYI,当我尝试在Android上运行这个代码时,我看到这个错误：

也许这个项目有一些有用的代码？ http://code.google.com/p/android-scripting/
解决方法
我发现在Android上使用LuaJ的一种方法！
