I've been using the app all day. Just went to send a new compile and the bridge is working, but the install button does nothing. Restarted b4a on PC, restarted phone, manually removed app, still the same. Install from unknown sources is OK and I've using the bridge so the verify apps over USB is not enabled.
Any ideas what may cause this? Been pulling my hair out the last hour trying to get it working again!
Try to change the package name and then install it. If it doesn't work then you will need to switch to USB debug mode. It will give you more information.
