Hi @karishmab

The current version of SQLCipher for Android is 3.5.3; we would welcome a test case for the crasher you are seeing. Thanks!

Hi Nick,

Confirmed that I’m seeing the same issue with 3.5.3 as well. How can I submit the new test ? I don’t have permissions to upload attachments or push my branch up.

Thanks,
Karishma

Hi @karishmab

You can fork the SQLCipher for Android test suite, define a new test, add it to the runner, finally executing it on either a device or emulator. Once you are able to reproduce it you can send us a pull request. Thanks!

Pull request is on its way. Thanks!
