how can i access the call logs?

I want to create an app that shows you your call log (and yes, i know that every phone in the world comes with a default phone app that shows you that already).

is it possible in Kodular?

The way call log apps work is every time somebody calls, they record it. You’d probably not be able to access the call logs or record the calls, because first, the call log apps don’t want malware stealing call logs, so they probably keep it private. Second, if you’re going to publish your app to Google Play, they might deny your app. Third, you’d need to run in the background, so you might have some trouble with that. Especially on Samsung phones, because they encourage users to not let stuff run in the background.
