我做错什么了吗？

提前谢谢

我不确定这是否有用。指示对于11.2.0，您必须使用CompileSDK版本26：当您将应用程序的Play services依赖项升级到11.2.0或更高版本时，还必须更新应用程序的build.gradle，以指定至少26的CompileSDK版本。为什么构建脚本块在两个gradle文件之间拆分？通常它只存在于根build.gradle中。还有，这是什么：

classpath'com.android.tools.build:gradle-experimental:0.9.3'

？您不想改为：

com.android.tools.build:gradle:2.3.3

？尝试将compileSdkVersion更改为26。。没有帮助。。还尝试从应用程序生成文件中删除buildscript块。。没有帮助。。将类路径“com.android.tools.build:gradle实验：0.9.3”替换为com.android.tools.build:gradle:2.3.3也没有帮助：/I我不做NDK构建，也不熟悉您的构建方法。这表明从

gradle.0.9.3

到

gradle:2.3.3

需要进行许多更改。当您尝试

2.3.3

时，是否进行了指南中描述的所有更改？Ahmm。。让我看看是否可以用新的gradle更新我的项目。。。谢谢我不确定这是否有用。指示对于11.2.0，您必须使用CompileSDK版本26：当您将应用程序的Play services依赖项升级到11.2.0或更高版本时，还必须更新应用程序的build.gradle，以指定至少26的CompileSDK版本。为什么构建脚本块在两个gradle文件之间拆分？通常它只存在于根build.gradle中。还有，这是什么：

classpath'com.android.tools.build:gradle-experimental:0.9.3'

？您不想改为：

com.android.tools.build:gradle:2.3.3

gradle.0.9.3

到

gradle:2.3.3
