1.2.2beta2的安卓版evalString可用么

Creator 2.x
#21

这就比较对了，这是 1.2 到 1.3 的接口改变导致的

需要把 _global->get() 改成 _global.ref().get()

还有，你既然在调试阶段，就不要用 Creator 来进行编译了，出了错不方便看，直接用 Xcode 编译会效率高很多

ios的按照这个修改后，可以得到返回值啦。

安卓的编译报错：

这一行把 evalString 的第二个参数去掉

按照这个修改，可以编译通过了：
Cocos2dxJavascriptJavaBridge.evalString(“console.log(’######java onEnterForeground#######’);”);
把这个语句放在activity的onpause里可以执行。

但是放在helper的onEnterForeground方法里就直接fatal 闪退了，在1.3里为什么放在这个位置就可以执行呢？需要怎么改才有可能可以在这调用呢？

#25

这应该是因为第一次进入的时候 JS 环境还没有准备好，你可以在 onEnterForeground 中检查一下

ScriptingCore::getInstance()->getGlobalContext()

如果 context 已经存在就可以调用，否则不可以调用

#26

我在onEnterBackground设置了一个参数，可以判断了，然后调用成功了，非常感谢panda大神耐心细致的解答和帮助：）
解决了游戏内手动暂停后，切出切入的暂停问题。感谢panda和cocos团队。

另：1.3的不用判断是否js环境已经准备好了。
