将 Android Studio 升级到 2021.1.1 版本（Android Studio Bumblebee）后，在尝试同步 gradle 文件时，我遇到了以下错误：

ModelCache.safeGet(androidProjectResult.androidProject::getNdkVersion, "") must not be null

有什么方法可以解决/修复这个问题吗？

我遇到了这个错误，通过进入我的项目的local.properties文件并添加以下行来解决它：

ndk.dir=C\:\\Users\\myusername\\AppData\\Local\\Android\\Sdk\\ndk\\23.1.7779620

我建议你使用你的ndk目录路径来尝试。

编辑：一段时间后，当我尝试同步gradle时，我需要再次解决这个问题，我通过进入“文件” -> “项目结构”并在“模块” -> “属性”下选择最新的ndk版本来解决它。

编辑2：在我清除缓存并重新启动之后，我需要再次解决这个问题，上述解决方案不起作用。最初我有些犹豫要将其添加到我的build.gradle中，因为其他人也共享这个项目，但是对我来说没有其他办法可行。这是代码：

android {
   ndkPath "C:\\Users\\myusername\\AppData\\Local\\Android\\Sdk\\ndk\\23.1.7779620"
}

接着，我需要从local.properties文件中删除ndk.dir这一行。似乎只有其中一个可以使用。

这不是最佳答案，根据Android Studio文档，它说：“使用ndk.dir属性找到了NDK。此方法已弃用，并将在未来的版本中删除。请从local.properties中删除ndk.dir，并在项目中的所有本机模块中设置android.ndkVersion为[23.1.7779620]。https://developer.android.com/r/studio-ui/ndk-dir”实际上，如果您在本地属性中有ndk.dir，则会收到错误提示，提示您应该删除该设置，并且在未来将不再支持。 - Kenneth Argo

尝试升级到 Android Gradle 插件 4.2.0+，并检查许可证，这对我有效。

yes | ${sdk}/cmdline-tools/latest/bin/sdkmanager --licenses

- Petr Kolman

你是正确的，AS 2021.1.1与AGP 4.1.0+不兼容。 - ipcjs

我因为升级到 Android Studio Bumblebee 而花费了几个小时解决这个问题。以下是我找到的最终解决方案。

打开“文件/项目结构”菜单，从此屏幕中的组合框定义 NDK 版本，然后你就完成了：

请查看以下示例截图：

要查找您所使用的NDK版本，请参见https://dev59.com/pVoV5IYBdhLWcg3wJ8Ab#36948929。 - Ian Osawaye

请前往您的SDK管理器，按照这个指示下载NDK。

按照这个指示找到您的NDK位置。

并在您的应用程序的build.gradle文件中指定它，如下所示-

android {
  ndkPath "/Users/ndkPath/ndk21" 
}

再次同步您的项目，然后重新构建它。

ndk.dir的值不再应该在您的应用程序的local.properties文件中设置，对于这个ndk.dir设置的支持将在未来版本中被移除。Android Gradle插件默认设置NDK版本，但如果您需要特定版本的NDK，可以在build.gradle中设置android.ndkVersion。

从local.properties中删除ndk.dir=/path/to/ndk。
进入android部分的build.gradle，添加ndkVersion='所需的ndk版本'

例如:

android {

ndkVersion '23.1.7779620'

在 android.ndkPath 中添加 ndk 路径。

或者，

添加 ndkVersion '23.0.7599858'（如果您使用此方法，则在某些情况下，如果其他库模块使用了 ndk，则必须在其版本中添加版本）。

- Bhavin Patel

我的项目之前没有添加ndkPath也能正常工作，有没有办法在不添加ndkPath到gradle构建文件的情况下继续进行，因为这是一个被多人使用的项目。 - Rawlin Crasto

在新的 Android Studio Bumblebee | 2021.1.1 中，当您通过从模板中选择 Native C++ 来创建新项目时，该项目中没有定义 ndk 的路径或版本，因此您需要尝试升级 gradle 版本，并相应地更新 gradle-wrapper.properties。我没有尝试过，但也许这会有所帮助。 - Bhavin Patel
