一、报错信息

在 Android Studio 中编译工程时报如下错误信息 :

AGPBI: {"kind":"error","text":"Invoke-customs are only supported starting with Android O (--min-api 26)","sources":[{}],"tool":"D8"}
AGPBI: {"kind":"error","text":"Static interface methods are only supported starting with Android N (--min-api 24): Landroidx/constraintlayout/core/motion/utils/TypedValues$Attributes;getId(Ljava/lang/String;)I","sources":[{}],"tool":"D8"}FAILURE: Build failed with an exception.* What went wrong:

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 1.7 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 1.8 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 1.8 1.8 即可 ;

           android {compileOptions {sourceCompatibility 1.8targetCompatibility 1.8}}

也可以写成如下形式 ;

android {compileOptions {sourceCompatibility JavaVersion.VERSION_1_8targetCompatibility JavaVersion.VERSION_1_8}
}
