I want to make an alarm clock with the ability to select ringtones, a picture that will appear, and so on. And the funny thing is that I know how to implement this part. But the problem is at the very beginning.
I decided to use TaifunAlarm as the basis, then change the design and add the elements that I need (melodies, pictures and so on). But first, I just copied the test project from the extension page.
I built the apk from that project, did not add anything from myself. But when I tried to test it, I got the error “Error 601: No correspond activity was found.”
I set the date, click Set and then this error.
