Android 8.1 - invalid channel for service notification
See original GitHub issuei’m develope ionic app and there i’m used this plugin.
after opening my app and the app is loaded, i called the function “backgroundmode.enable()”. after a short timespan app stopped with the issue:
invalid channel for service notification
after removing the usage of this plugin the app isn’t stopped and runs all the time. all fine.
so, i checked this. i have added the plugin usage again and the exception came back. i removed it again, exception is gone
this is the full stacktrace, which is shown in Logcat (Android Studio):

Below changes in the cordova-plugin-background-mode worked for me. Crash issue is resolved as well as background plugin is working fine.
