What happens if you do not close the cursor in the android application?

Question

Android

Suppose we opened the cursor to the database, but did not close it anywhere. The user has closed the application. Will the cursor be closed/destroyed or will it hang in the device's memory until it is rebooted.

Answer 1

The garbage collector will kill it, and when SQLiteDatabase is deleted, a warning will pop up in the log that you had non-closed databases. In general, nothing fatal, but it is still better to close the database when it is no longer needed, if possible.
