If you are using NDK, verify the ndk_ ...... 好家伙这又是个什么鬼. NDK缺少一个“platforms”目录。如果您正在使用NDK请验证NDK。将dir设置为有效的NDK目录。目前它被设置为D: AndroidSDK\ndk-bundle。如果不使用NDK请从ANDROID_NDK_HOME或local中卸载NDK变量。属性删除此警告。 2.1 解决第一个问题 既然说少了就装个吧。 下载链接https://developer.android.google.cn/ndk/downloads/  下载解压zip文件 得到一个 android-ndk-rXXb 的文件夹直接解压然后把该文件夹下的所有文件都移动到你的sdkndk-bundle 文件夹下。 再配置个环境变量重启 AS 解决问题。 2.2 解决第二个问题 Build file F:\android_studio_workspace\flutter_app2\flutter_app2\android\app\build.gradle line: 25 找到 flutter SDK 路径下的 \flutter\packages\flutter_tools\gradle\flutter.gradle 文件。 把 gradle 版本改低一点。    博客地址https://www.cnblogs.com/niceyoo
