Question

我在Android应用程序中包含的每个第三方库项目中都有 NoClassDefFoundError 。

当我使用我的应用程序配置Google Map V2时，我收到以下错误;

以及其他应用程序中，我对其他类别的库项目也有同样的错误。

我使用下面的软件配置：

**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

您可能需要升级＆＃34; Build-Tool版本＆＃34;一些最新的。

Answer 2

由于GMS库与项目位于同一个工作区，我猜它只是没有链接。

右键单击Eclipse Package Explorer，从左侧列表中选择 Properties ，然后选择 Android 。

点击右侧窗格底部的“添加...”按钮，然后选择google-play-services-lib（或类似内容）将该库添加到列表中。

检查 project.properties 文件（在项目的根文件夹中）。它应该有这样的一行：

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

现在尝试清理项目再次构建它。希望它会有所帮助。
