If you want to trigger backups from another app, enable 3rd party integration in Advanced Settings and send the broadcast intent com.zegoggles.smssync.BACKUP. This will work even when Auto Backup is disabled.
But, whenever I run it, I get the following error:
So, is there anything else I need to do, in order for Automagic to be able to access this app's intent?29.03.2019 16:23:54.011 [Flow3] End executing action 'Start Activity: com.zegoggles.smssync.BACKUP ' and exception No Activity found to handle Intent { act=com.zegoggles.smssync.BACKUP flg=0x10000000 }
