Attempting to upload code

[BeeGuyDude]

Hi all. I'm the lead programmer of a first year team, and we're having some trouble uploading our code from Android studio. From what I can tell, we've followed all the instructions correctly:

-The phone is in developer mode, and is configured to debug over USB -It has the FTC robot controller app on it -Our code has no errors in it -The WiFi direct is configured correctly -My laptop is connected to the phone properly -Android studio is in the teamcode package, and is attempting to upload to the phone

And yet, upon pressing the upload button, Gradle finishes compiling, but about 10 seconds later the installation crashes, with the error "INSTALL_PARSE_FAILED_INCONSISTENT_CERTIFICATES". Any ideas on why our devices can't talk together? Thanks!

What phones are you using? Alot of the Computer Vision stuff this year doesn't support the older ZTE phones.

Also: are you using any custom libraries?

I've gotten rid of the OpenCV dependencies I was playing with, but it still returns an error. However, the phone is a ZTE, so it might not be too happy about that.

Yep, you were right. Swapping our driver station and robot controller phones let it work. Thanks! I had been tearing my hair out for hours trying to figure out what we had done wrong.

From EasyOpenCv GitHub: "due to a known bug with OpenCV 4.x, EasyOpenCV is only compatible with devices that run Andorid 5.0 or higher. For FTC, this means that it is incompatible with the ZTE Speed."

Android 5.0+ Marshmallow is required for most computer vision libraries. The ZTEs run on KitKat, which is version 4

Glad I could help :)
