二、解决方案

上述报错是由于在 主应用 中 , 设置的 Java 版本为

1.7

版本 , 但是在依赖库 " constraintlayout-core-1.0.0.jar " 中 , 使用的 Java 版本是

1.8

版本 , 因此报错 ;

这里按照 错误提示中的修改方法 , 将 " build.gradle # android # compileOptions " 中的 sourceCompatibility 和 targetCompatibility 属性修改为

1.8

即可 ;

代码语言：javascript复制

           android {
               compileOptions {
                   sourceCompatibility 1.8
                   targetCompatibility 1.8
               }
           }

也可以写成如下形式 ;

代码语言：javascript复制

android {
    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
    }
}
