I am trying to sideload an APK onto my Clover Flex Dev Kit and running into a couple of issues. The first issue is that I am running into is ADB recognizing my Clover Flex. It only recognizes the Clover Flex device once I connect it through the Clover Example POS using the USB connection. The next issue that I am running into is installing the APK onto the Clover Flex Dev Kit. I tried uploading the APK onto the dev dashboard and I am getting "V2 APK signature scheme is not supported". I also tried to sideload the app using ABD and I keep getting "Failure [INSTALL_PARSE_FAILED_NO_CERTIFICATES". Any suggestions on how to install the APK successfully on the Clover Flex Dev Kit? Thank you!
