ModelCache.computeIfAbsent must not be null

Question

After upgrading to Android Studio 3 Canary 4 I've got this error:

Gradle sync failed: Argument for @NotNull parameter 'key' of com/android/tools/idea/gradle/project/model/ide/android/ModelCache.computeIfAbsent must not be null

Anyone else has the same problem?

    }

```

and module build.gradle:

buildToolsVersion '25.0.3'

I am using Android Studio 3.0 Canary 7. I changed classpath as 'com.android.tools.build:gradle:2.3.1' and I also changed buildToolsVersion as '25.0.0' and the problem was resolved for me. – Fivepenny

Had the same problem when I got Android Studio Bumblebee ModelCache.safeGet(androidProjectResult.androidProject::getNdkVersion, "") must not be null

This worked for me, go to File > Project Structure > Modules > and select NDK Version ex. 21.4.71. ..
