Not sure if this is related, but we have something similar with our Intune Wrapped app. It is Cordova based app, fails at start. Place is different, but looks like something goes very wrong with it once wrapped. Similar behavior reported by other developers too. Some more details here: https://issuetracker.google.com/issues/316396709 Our latest update is that it now fails on start and can be started later with no issues. Previously, it would start failing after some time and it was enough to clear cache to get it working for a while again. We have changed Intune policy to have minimum possible restrictions. For us, this started to happen suddenly on an app that was OK, no new releases issued. Issue happens randomly, no idea how to reproduce it. As for now, it looks like app works fine if not wrapped. On devices that we have seen crash every day, it works for a week or two now, no issues reported. |

Hi @E-N-G-XOR, thanks for the report. Is this your first time wrapping your app or did this ever work previously? From the logs provided it looks like the crash in caused Android's foreground service launch restrictions, https://developer.android.com/about/versions/12/behavior-changes-12#foreground-service-launch-restrictions 01-23 16:48:22.909 31689 31689 E ANDROIDRUNTIME: CAUSED BY: ANDROID.APP.FOREGROUNDSERVICESTARTNOTALLOWEDEXCEPTION: STARTFOREGROUNDSERVICE() NOT ALLOWED DUE TO MALLOWSTARTFOREGROUND FALSE: SERVICE AERO.INFORM.UXWRAPPER.FX.SC.APPNAME/AERO.INFORM.ANDROID.BACKGROUND.GSBACKGROUNDSERVICE Is "AERO.INFORM.UXWRAPPER.FX.SC.APPNAME/AERO.INFORM.ANDROID.BACKGROUND.GSBACKGROUNDSERVICE" a service in your application? If so, you may want to check that the service you are trying to start adheres to Android's restrictions. |
