Resolving the SQLiteDatabaseCorruptException in Kotlin Multiplatform: A Step-by-Step Guide

Migrating a database from an unencrypted format to an encrypted one can be challenging, especially when dealing with cross-platform projects like those built in Kotlin Multiplatform. One common issue developers face during this migration is the SQLiteDatabaseCorruptException, particularly the message indicating that the file is not a database while compiling the PRAGMA journal_mode.

In this guide, we will explain the cause of this exception and provide you with a step-by-step solution to resolve it.

Understanding the Problem

As described by a developer grappling with Kotlin and SQLite on both Android and iOS, the project was intended to migrate an unencrypted database to an encrypted format. Despite successfully encrypting the database and seeing the expected old data, the application crashed with a specific error message related to database corruption.

Key Error Message

The error message encountered was:

This error often indicates that the database version was not correctly updated during the migration process, which can lead to unexpected behaviors.

Step-by-Step Solution

The solution to this problem typically involves ensuring that the database version is correctly managed during migration. Let's break it down into organized steps.

Step 1: Retrieve the Current Database Version

You need to implement a method to retrieve the current version of the user database. Here’s how you can do this:

Step 2: Updating the Database Version in Your Migration Method

Once you successfully retrieve the database version, the next step is to ensure that this version is set correctly during the migration process. You can do this with the following code snippet:

Final Thoughts

By implementing these steps, you will ensure that the database version is accurately managed, which should prevent the SQLiteDatabaseCorruptException. This check will help you safely migrate your database to an encrypted format without encountering unexpected errors.

If you encounter any further issues during your migration process, ensure to check your database handling logic and confirm that the version is correctly set and retrieved.

With this guide, we hope your Kotlin Multiplatform project can run smoothly with your encrypted database!
