Question

我有一个使用Java OpenJDK7在Ubuntu上创建的JAR。我想要做的是将这个JAR包含到我的Android应用程序中。当我将JAR添加到libs文件夹并尝试运行应用程序时，我收到以下错误

com.android.dx.cf.iface.ParseException: bad class file magic (cafebabe) or version (0034.0000)

我读到这可以通过使用JDK 1.7来编译应用程序来解决。我这样做了，我仍然有同样的错误

Gradle console

我正在使用Android studio 1.5

有人可以帮我修复此错误吗？

Answer 1

检查你的libs。

我遇到了同样的问题，因为我的一个.jar有这个导入。＆＃34; import org.apache.commons.codec.binary.Hex;＆＃34; ，这是不存在的。

com.android.dx.cf.iface.ParseException：错误的类文件魔术（cafebabe）或版本（0034.0000）
