安卓工作室错误 : static interface method invocations are not supported in -source 1. 7

Question

Error:(100, 48) error: static interface method invocations are not supported in -source 1.7 (use -source 8 or higher to enable static interface method invocations)

该行看起来像这样:

field = SomeInterface.someMethod("","","");

和界面:

public interface SomeInterface extends AnotherInterface {
      public static SomeInterface someMethod(String arg1,String arg2,String arg3) throws IOException {
            return someMethod(arg1,arg2,arg3,SOME_CONSTANT,ANOTHER_CONSTANT);
      }
}

如何解决这个问题？

由于静态接口(interface)方法调用是在 Java 8 中引入的，因此您必须 add the Java 8 compatibility options在您的 build.gradle 文件中启用 Java 8 语言功能:

android {
    ...
    compileOptions {
        sourceCompatibility 1.8
        targetCompatibility 1.8
    }
}
