更新到 Android Studio Bumblebee 2021.1.1 后 Android studio 中的 Gradle 项目同步出错

Question

将 Android Studio 更新到版本 2021.1.1 (Android Studio Bumblebee) 后，我在尝试同步 gradle 文件时收到以下错误

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

这是进一步的堆栈跟踪

om.intellij.openapi.externalSystem.model.ExternalSystemException: ModelCache.safeGet(androidProjectResult.androidProject::getNdkVersion, "") must not be null

关于如何解决这个问题/解决这个问题有什么想法吗？

Answer 1

我遇到了这个错误，并通过进入我的项目的 local.properties 并向其添加以下行来修复它：

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

无论你的 ndk 目录路径是什么，我都会尝试它。

编辑：过了一段时间，当我尝试同步 gradle 时，我需要再次修复这个问题，我通过进入“文件”->“项目结构”并在“模块”->“属性”下选择最新的 ndk 版本来完成此操作。

编辑2：使我的缓存无效并重新启动后，我需要再次修复此问题，但上述解决方案不起作用。由于其他人共享这个项目，我最初犹豫是否将其添加到我的 build.gradle 中，但其他方法对我来说都不起作用。这里是：

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

接下来，我需要从 local.properties 文件中删除 ndk.dir 行。似乎同时只能其中之一起作用。
