I just merged to 4.3 from 4.0, Android Studio 3.0, the libraries still come up as unresolved?
import org.firstinspires.ftc.robotcore.external.tfod.TFObjectDetector; import org.firstinspires.ftc.robotcore.external.tfod.Recognition;

I'll try downloading the zip file...

sashajeltuhin commented 6 years ago

4.3 zip worked for me

Try FIle > Invalidate Caches / Restart in Android Studio. Once I did that, everything was found.

An alternative is to close the project and then do another 'Import' of the same project and same directory. AS treats it as a new project and doesn't use any cached information from it.

cmacfarl commented 6 years ago

+1 Invalidate caches.

Android Studio can get confused when you add new dependencies.

ftcteam8045 commented 6 years ago

Invalidating caches/Restart did NOT fix my problem, but closing and re-importing the local project did. Thanks for the help.
