I have the crash of my app without any exception

[e16din]

I always see the lines like this in the LogCat:

E/Robin/ MainActivity: Key: myKey value : 1
E/zygote64: The String#value field is not present on Android versions >= 6.0

The crash disappears when I remove the Robin

Do you have crash log? If not try this to capture the log and share here. Thanks

No I do not.

I try this to capture the log, and the folder is empty too, no exceptions at all.
