Android 编译错误 Error: Invoke-customs are only supported starting with Android O (--min-api 26)

Android Studio编译报错：

Error: Invoke-customs are only supported starting with Android O (–min-api 26)

解决方案：

build.gradle文件中android节点下增加：

 compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
    }
