本文主要是介绍（笔记）NDK is missing a “platforms“ directory. If you are using NDK, verify the ndk.dir is set to a val，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

一、问题

NDK is missing a "platforms" directory.
If you are using NDK, verify the ndk.dir is set to a valid NDK directory.  It is currently set to D:\AndroidStudioSDK\ndk-bundle.
If you are not using NDK, unset the NDK variable from ANDROID_NDK_HOME or local.properties to remove this warning.

二、解决方法

1. 勾选NDK，点击OK

2. 点击右下角的Show Package Details展开所有的列表，然后在NDK（Side by Side）中选择你想要安装的NDK的版本

（1）如果选择下载全部NDK，则在NDK（Side by Side）前面打个钩

（2）如果选择部分下载，那么就在NDK（Side by Side）的列表中勾选任意的NDK版本

三、如果安装了NDK，sync还是失败的话，升级一下Gradle，视个人情况而定，我这里是最新的

1. 在gradle-wrapper.properties修改

distributionUrl=https\://services.gradle.org/distributions/gradle-6.5-all.zip

2. 在project的build.gradle文件修改

dependencies {classpath 'com.android.tools.build:gradle:4.1.1'// NOTE: Do not place your application dependencies here; they belong// in the individual module build.gradle files
}

3. 请注意你的local.properties文件下的ndk.dir目录是否与你下载的ndk目录一致
