Question

我的NoClassDefFoundError在每一个第三方库的项目包括在我的Android应用程序。

当我使用我的应用程序配置Google Map V2时，出现错误;

也在其他应用程序中，我得到同样的错误，其他类包括的库项目。

我用下面sofware配置：

**Windows 10 64-bit 
Eclipse Luna Service Release 2 (4.4.2) - 64-bit 
Java SE – jdk-7u79-windows-x64 
     jre-7u79-windows-x64 
Android: 
    Android SDK Tools – 24.3.4 
    Android SDK Platform Tools – 23 
    Android SDK Build-Tools – 18.0.1 
    Google Play Services – Rev. 26** 

请帮我解决这个问题。我需要做哪些配置更改？

Answer 1

您可能需要将“Build-Tool版本”升级到最新版本。

Answer 2

由于GMS库与您的项目在同一个工作区中，我猜它只是没有链接。在Eclipse Package Explorer中您

单击鼠标右键，从左边的列表中选择属性，然后的Android。

点击“添加...”按钮，在右侧窗格中的底部，然后选择谷歌播放服务-LIB（或类似的东西）的库添加到列表中。

检查您的project.properties文件（在您的项目的根文件夹中）。它应该有这样一行：

android.library.reference.1=../google-play-services-lib 

现在清理项目，尝试再次构建它。希望它会有所帮助。
