How to find out what kind of error and in what place this error appears and how to fix it?

Question

Android

I myself cannot provoke this error on my devices, I don’t know where it comes from, but reports come in the playconsole, I copied everything that was in the report.
I use the sqlite database and the DBHelper class, I call different query and rawQuery queries to it, I also use the update method (for cells). The base seems to be closed everywhere after each request.

Answer 1

The stacktrace is cut off. For this piece - no way to understand. In the full stacktrace, your files will appear with the lines in which the exception was thrown.
