意外的顶级异常：错误的 class 文件魔术，在 Android 中

我在 Gradle 和 IntelliJ 中遇到了同样的错误。

我无法弄清楚实际发生的问题。请帮忙。我正在使用 Java 1.8 来编译这个程序。有没有办法使用 Java 1.8 来做到这一点？有必要用1.6吗？如果是这样，我应该如何使用 Java 1.6?

Answer 1

检查您用来编译类的 Java 版本。

您需要使用 Java 6 或 7 进行 Android 开发。 Java 最近添加了 7 支持，但其功能有限，因此请使用 6 以获得最大兼容性。

Answer 2

这个问题的原因是java版本。它应该是 jdk 1.7 或更小。卸载你的1.8版本并安装1.7并更改环境变量中的路径。
