Android Question An error occurred while trying to get the recorded data into an SQLite table

[Darsiar]

An error occurs periodically when trying to retrieve data from a table. In other cases, there is no error.
In all cases, the debugger shows that the data is written to the table equally correctly.
I enclose the code of the entire module and a description of the error.
