无法在Netbeans上编译Android hello world

Question

这是我在这个非常有用的网站上的第一篇文章！

经过30分钟的谷歌搜索和发现非常有用的自动搜索功能，当你输入你的问题的名字，我想是时候我终于做了一个帐户，并问！

好吧，这是我第一次得到我的手脏，我看到一个错误直打在我的脸上，在形式：

我明白了一些编码概念，但是我仍然是非常新的，我想知道是什么导致这种情况发生在这个网站的有帮助的人，谢谢！

Answer 1

听起来像一个记忆问题？

Error occurred during initialization of VM
Could not reserve enough space for object heap

（EMPH矿）

Answer 2

嗯，我有完全相同的错误，当我试图运行样品VS-的Android（https://code.google.com/p/vs-android/）应用。

经过大量的mu I后，我实际上并不知道是什么原因造成的，但我肯定找到了解决办法。

显然由于某种原因，JVM无法初始化，因为它觉得系统中没有足够的内存。解决方法是将JVM设置为初始化512MB的堆大小而不是1024MB的默认大小。为了做到这一点，做到以下几点：

Go to Start->Control Panel->System->Advanced->Environment Variables->System Variables->New: 

Variable name: _JAVA_OPTIONS <br> 
Variable value: -Xmx512M 

这解决了这个错误对我来说，虽然我仍然有问题，部署到我的设备，但是这是一个不同的问题，至少它编译并创建了一个APK - 我可以只复制到设备上并运行它。
