Java 点击AVD"；“创建设备”；按钮抛出NullPointerException

有很多帖子抱怨AVD创建设备，但大多数都抱怨按钮被禁用。还没有看到我的具体问题在任何地方得到解决

我正在尝试创建一款看起来像我的三星Galaxy S4 Mini的设备。我正在32位Windows7系统上从命令提示符启动AVD管理器。如果有什么关系，Eclipse将关闭

当我点击创建设备按钮时，我得到了这个

C:\java\adt-bundle-windows-x86-20140702\sdk\tools>android.bat avd

有人能帮我吗？非常感谢您的帮助

谢谢你，我也遇到了同样的问题，删除并重新安装所有与Android相关的东西（eclipse、SDK manager和JDK），卸载时请确保删除所有文件和文件夹。

我还建议搬到Android Studio。

我在Android Studio 1.5.1中也面临同样的问题：(
