net.sqlcipher.database.SQLiteCursor.finalize() timed out after 10 seconds

[wongk]

Our cursors are all closed through normal application flow prior to finalize. We have verified this using strict mode.

A pull request has been opened to address this issue: #311.

Hello @wongk,

Thank you for this report, we have reached out in #311 with additional follow up.

With the 3.5.7 version, I have many reports of this crash.
The lines are a bit different, but the consequence is exactly the same.

@g123k have you verified that you are closing all cursors when you are done with them? This could happen if you don't close them in a finally block.

Still same error? Is there any new update about it? How can I reproduce I do not know.

version 4.5.3..

@melikeey the latest release of android-database-sqlcipher was 4.5.4, however, the project has been deprecated in favor sqlcipher-android, the long-term supported replacement.
