Android Studio 升级 3.6 之后，sync 原本正常的 Module 时提示 NDK 问题：

NDK not configured. Download it with SDK manager. Preferred NDK version is ‘20.0.5594570’. Log: /Users/shawn.xiafei/Workspace/AndroidStudio/Marmot/iCtrl/.cxx/ndk_locator_record.json

上面的报错信息中指出了log文件，其内容如下：

  1. {
  2.   "messages": [
  3.     {
  4.       "level": "INFO",

  38.     },
  39.     {
  40.       "level": "ERROR",
  41.       "message": "No version of NDK matched the requested version 20.0.5594570. Versions available locally: 20.1.5948944, 21.0.6113669"
  42.     }
  43.   ]
  44. }

解决方法：

根据上面 log 信息的第一条，在 Module 的 build.gradle 中加入如下 NDK 版本定义：

  1. android{
  2.     compileSdkVersion 28
  3.     buildToolsVersion "29.0.2"
  4.     // 加入下面这行代码。
  5.     // 参数是SDK Manager 里面 看到的NDK版本号，也可以在 sdk/ndk/ 下面找。
  6.     ndkVersion "21.0.6113669"  
  7. }

加入 ndkVersion 之后再次 sync，问题就解决了。

如果还没有解决，可以尝试 log 中后面几条提示信息。
如果还没有解决，那就按 AS 的提示，下载对应的版本吧。
