[Help]Cocos2dxLuaJavaBridge调用LUA回调出错

Cocos2d-x Lua
#1

调用代码：从ui线程中调用如下静态类

static void callLuaLogin(final String accessToken) {
runOnGLThread(new Runnable() {
@Override
public void run() {
Log.d(TAG, “call lua function loginResultCallback”);
Cocos2dxLuaJavaBridge.callLuaFunctionWithString(loginResultCallback, accessToken);
}
});
}

quick-cocos2d-x版本https://github.com/chukong/quick-cocos2d-x上的最新master分支

大神们帮忙看看，看起来像JNI调用出错了

问题解决了，其实这个调用是成功了的，不过lua的回调里接着调用了getUDID方法，而PSNative没初始化直接挂了，日志上看不出什么错误，上android单步调试才发现接着进入了PSNative里，寒

把LuaJavaBridge调用的日志贴上来

java方法要在 UI 线程里跑。你检查一下这里。

看最后的错误信息应该是 lua vm 已经因为跨线程原因被搞坏了。

#5

请教楼主，我为啥用lua调java就提示 :0: attempt to index global ‘LuaJavaBridge’ (a nil value)

#6

请楼主无视上面的问题，已解决

#7

你好，新手一个，想用lua调用java后台接口，查了一些资料，有点乱，可否指点一下，我本地的环境是cocoa Ide ＋ Quick-Cocos2d-x + lua?还需要其他什么的吗？多谢了
