Getting warning "NDK is missing a 'platforms" directory.' with no NDK
提问by CorayThan
I've got a project that only uses the Android SDK, not the NDK, but I'm getting warnings whenever I build with gradle about the NDK:
我有一个只使用 Android SDK 而不是 NDK 的项目，但是每当我使用关于 NDK 的 gradle 构建时，我都会收到警告：
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 /usr/local/opt/android-sdk/ndk-bundle.
If you are not using NDK, unset the NDK variable from ANDROID_NDK_HOME or local.properties to remove this warning.
NDK is missing a "platforms" directory.

Seems like a pretty clear warning. I'm not using the ndk, so there is no ndk-bundlein my android-sdk. The issue is that I don't have an ANDROID_NDK_HOMEset, and my local.propertiesfile (which appears to be generated by Android Studio) doesn't set the NDK:
似乎是一个非常明确的警告。我没有使用 ndk，所以ndk-bundle我的android-sdk. 问题是我没有ANDROID_NDK_HOME设置，而且我的local.properties文件（似乎是由 Android Studio 生成的）没有设置 NDK：
sdk.dir=/usr/local/opt/android-sdk
sdk.dir=/usr/local/opt/android-sdk
I do have an ANDROID_HOME environment variable:
我确实有一个 ANDROID_HOME 环境变量：
ANDROID_HOME=/usr/local/opt/android-sdk
ANDROID_HOME=/usr/local/opt/android-sdk
System is a mac, but we seem to get the same issue in Docker. Anyone know how to get rid of this warning?
系统是 mac，但我们似乎在 Docker 中遇到了同样的问题。有谁知道如何摆脱这个警告？

Please refer to these two links:
请参考这两个链接：
This is caused by upgrading to Android gradle plugin 2.3 (com.android.tools.build:gradle:2.3.0).
In previous versions of the plugin the databinding package name (where the BR file is generated) was provided on an annotation in a generate file. In the new version it's passed as a annotation processor option which is now handled.
An updated version will be available soon, a temporary workaround is to simply use the previous android gradle plugin 2.2.2
这是由于升级到 Android gradle 插件 2.3 (com.android.tools.build:gradle:2.3.0) 引起的。
在以前版本的插件中，数据绑定包名称（生成 BR 文件的位置）在生成文件的注释中提供。在新版本中，它作为注释处理器选项传递，现在已处理。
更新版本即将推出，临时解决方法是简单地使用以前的 android gradle 插件 2.2.2
