Q: What was the old package name? com.github.ppartisan.simplealarms? Q: What's the new package name? Did you do a global "Find" in Android Studio for *ALL* instances of the old name (.java *AND* .xml files), "clean" and "rebuild" everything? — paulsm4, Oct 07 '20 at 05:25
yes, my old package name is com.github.ppartisan.simplealarms. I replace all files but Q.can you explain how to do a global find? — Nusry KR, Oct 07 '20 at 05:28
this issue is related to the package name change. you have used whole package name with class in some xml or something. Use Ctrl+Shift+F/Cmd+Shift+f to find usage of old package name and replace it with new one. — Pragnesh Ghoda シ, Oct 07 '20 at 05:30

I think you didn't change all of these package name of java code to com.example.taskreminder.ui(is it new package name right?). You need to make sure that no old package name by searching keyword com.github.ppartisan.simplealarms. you can refer to this solution: https://stackoverflow.com/a/29092698/5738042
