Problem with 4.7 prebuilt samples

Hi, i’m trying to use the camera calibration sample in the 4.7 prebuilt android sdk.

When i open the project with android studio i got this message :

The specified Gradle distribution ‘file:/opt/gradle/’ does not exist.

Same result on 2 computers ( one with new android studio just installed )

I don’t know what to do to get the sample working.

If anyone has a solution please share.

As an alternative if i have a working android project that i clone, can i copy these files in it ? :

My end goal is to use solvepnp to have the position and orientation of aruco markers in my working android project but i need to do a calibration.

Pleas post error message as text( robot could indexed it)
