每次我使用 < 坚固> 构建路径 & gt; 配置构建路径 & gt; 添加外部 JAR 的外部 JAR < / 坚固 > 我的Android 应用程序丢出一个例外, 并说 java. lang. noClassDefffoundError... 。
我做错什么了?
步骤 # 1 : 撤消您的“ 配置构建路径” 东西
第2步: 确保您正在使用最新的 SDK 工具以及 Eclipse 的 ADD 插件
步骤 # 3 : 在您的工程根根中创建 libs/ 目录
步骤4:将您的 JAR 复制到 libs/ 目录
您的 JAR 将被自动添加到您的构建路径中, 其内容将被自动添加到您的APK 中 。
这个是给我修的:
问题是,当使用属性 - Java 构建路径 - 添加外部 Jar 时,外部罐子不会默认地放置在 libs 文件夹中,而是被置于参考图书馆之下, 而不是安卓德依附关系之下, 这导致了 NoClass DefffoundError 。
