When I import an Eclipse project into Android Studio, I got this problem:
Gradle \'XNote\' project refresh failed
Error:Could not determine the class-path for interfa
Palanivelraghul was right. A Studio has to download the old version. Then it presented 3 different options after it was complete.
Choose the top option ~"Sync with 3.0.1".
Event Log:
Gradle sync started > Project setup started > Gradle sync finished > Executing tasks:
[:app:generateDebugSources, :app:generateDebugAndroidTestSources, :app:mockableAndroidJar] > Gradle build finished.
