当我尝试通过 Android Studio 导入我的项目时，我收到了这个错误。

我在项目中使用了 gmaps。如何解决此错误？

我在 Windows 7 - 64 位 PC 上使用 Studio 0.3.2 和 Gradle 1.9。

【问题讨论】：

你能把你得到的完整错误贴出来，也许是截图（或者是这样吗？）
请看一下日志文件。

【解决方案1】：

您可以使用 android studio 0.4.0。 Gradle 1.9 版与 Studio 0.3.2 不兼容。

【讨论】：

在我使用 ActionbarSherlock 和 HoloEverywhere 更新到 0.4.0 之前，我遇到了很多与 Gradle 相关的问题。这解决了它。

【解决方案2】：

作为 SUcpinar 的遗憾，您应该将 Android Studio 升级到 0.4.0。要升级，请转到文件 -> 设置 -> 更新，然后按“立即检查”。它帮助了我。

【解决方案3】：

我卸载了工作室，最后从开发频道下载了金丝雀版本并重新安装。
