nibbo Active Member Licensed User Longtime User Dec 3, 2020 #1 Getting a strange error: java.lang.NoClassDefFoundError: Failed resolution of: Landroidx/core/content/ContextCompat; I have read a few similar threads but they all imply a dodgy install, I have been developing with this install for over 3 years! This error happens in RuntimePermissions B4X: rp.CheckAndRequest(rp.PERMISSION_READ_PHONE_STATE) Anyone know what this error actually means? Thanks
