Hi @tankyag
It is difficult to say the exact cause of the error you are receiving. Depending on the version of DB Browser for SQLite you are using, it may or may not support the database file format you have directly. A few things you might consider:
- Try the latest nightly of DB Browser for SQLite available here
- Use the latest version of SQLCipher for Android (currently 4.1.13) more information here
- Attempt to access the database using the SQLCipher command line interface
- Execute
hexdump -C YourDatabaseFile.db
to see if it prints any plaintext schema or data information
