Android Application close Rad Studio 10.4.2

Recommended Posts

I have been with an issue a few days ago that I can not finish solving. I'm migrating an app developed for Android 6.0.1 with Rad Studio 10.2.3 to Android 9 with Rad Studio 10.4.2. When I start debugging, without touching anything at all, after a while I get this error that did not happen before:

---------------------------
Debugger Exception Notification
---------------------------
Project Application.apk raised exception class Segmentation fault (11).

When I go to see where the code was hung, the following appears:

I would check first if all the permissions handling is correct, there had been many changes.

If that doesnt helps, have you tried to recreate a new project under 10.4.2 and reset your project to the latest projects defaults ?

Thanks for answering! Yes, the handling of the permits is correct, I checked it several times.

With the app that I am having problems, sometimes I start to use it, it throws Segmentation Fault errors when it wants to do a SELECT to the SQLite database interchangeably. That is, it does it once, it does it twice, etc ... until it fails for a realloc.

A possible problem could be memory leaks due to the ARC that existed in 10.2 and now doesn't exist anymore, you have to Free the objects. There may come a point where your application crashes due to excessive use of memory.


I advise you to run on windows with ReportMemoryLeaksOnShutDown to confirm. If you can't run the entire app, at least part of the code.
