Question

这是我在这个非常有用的网站上的第一篇文章！

在Google搜索并发现非常有用的自动搜索功能30分钟后，当您输入问题的名称时，我认为是时候我终于开了帐户并问了！

好吧，这是我第一次弄脏手，我看到了一个错误直接击中了我的脸，形式为：

我理解一些编码概念，但是我仍然非常新，我想知道这个网站上有帮助的人是怎么回事，谢谢！

Answer 1

听起来像内存问题？

VM初始化期间发生错误 无法为对象堆保留足够的空间

Answer 2

当我尝试运行示例vs-android（https://code.google.com/p/vs-android/）应用程序时，我遇到了完全相同的错误。

经过大量的捣乱后，我实际上并不知道是什么导致它，但我肯定找到了解决方法。

显然由于某种原因，JVM无法初始化，因为它感觉系统中没有足够的内存。解决方法是将JVM设置为使用512MB的堆大小而不是1024MB的默认大小进行初始化。为此，请执行以下操作：

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

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

这解决了我的错误，虽然我仍然有问题部署到我的设备，但这是一个不同的问题，至少它编译并创建了一个apk - 我可以将其复制到设备上并运行它。
