Unsupported major.minor version 52.0问题解决办法

本文介绍了在Android Studio中更新SDK至23后遇到的问题及解决方案。当使用JDK1.7时,尝试生成APP会报错,更换为JDK1.8后问题解决。进一步分析发现将build tools版本从24.0.0回退至23.0.3即可避免错误。

重新配置android studio将SDK更新到23,结果使用JDK1.7无法生成APP,并提示 Error:java.lang.UnsupportedClassVersionError: com/android/dx/command/Main : Unsupported major.minor version 52.0,后面使用JDK1.8可以生成APP,因此分析是某个导入的包需求高版本的JDK,排查一圈下来发现将 build toole 24.0.0换成23.0.3即可。
