I'm working on Call Directory Extension. This extension was added, however I don't have any idea to execute this. Excuted this extension, and 'Choose an app to run' appeared, selected my main app, but it didn't seem to run. Of course added this app on Settings - Phone - Call Blocking & Identification.
I just added extension, and didn't write any code on both of the main app and extension. Do I need to add some code? Searched for several hours, couldn't find solution. Please help.
