Two activities with a same name can be created (also lead to a fatal crash)

[tingsu]

App version: 1.4.0
Platform: Android 6.0 emulator

STR:

1. fresh install the app and open the app
2. click "+" on top to create a new activity
3. Input "Test" and click the check symbol on the top
4. long click the newly created activity "Test"
5. click "delete"
6. click "+" on top again
7. input "Test" again and click the "recover" button, and click the check symbol on the top
8. click "+" on top again, input "Test" again, and click the "rename" button, and click the check symbol on the top
9. At this time we can see two "Test" activities are created with different color (maybe this is also a bug?)
10. long click the first created "Test" activity, and delete it
11. long click the second created "Test" activity, and edit it
12. the app crashes

Any update? Thanks a lot.

Thanks for the report. I have only quickly read at first, and as I saw you reporting for the Android Emulator, I did not put high priority on it, but I'll try to reproduce and take a closer look.

The main bug is in my eyes, that you seem to succeed to create two activities with the same name.

Hi @ramack, thanks for providing this nice and handy app. Can I know will this issue be fixed soon? It is a little wierd to be able to create two activities with same name.

[ramack]

The use case looks rather complicated, is that really so important for you? For sure it is a bug and it should be corrected, but it doesn't look critical to me. As I could not work for a long time on this app and some more important other issues are pending I don't want to promise anything here.
Except maybe that I will soon be more active here for this app!

Thanks for your reply! I just feel it would be better to fix this issue. I provided a reproducing video to ease the inspection and make the use case more clear (not very complicated:). I totally understand you are quite busy with other things. I know maintaining an app need a lot of time and efforts. Never mind. Thanks!

[ramack]

your report is fully clear, I am just not confident that this happens very often, as most user won't create and delete an activity two times, but as said I agree that it should be fixed but probably more later than sooner :-)
