android.database.sqlite.SQLiteException: Can't downgrade database from version 35 to 33

[hippiefahrzeug]

In order to upgrade my schema I've created my own SQLiteOpenHelper which does the upgrades at startup. In my last update, something bad happened: Users are reporting this error...

Caused by: android.database.sqlite.SQLiteException: Can't downgrade database from version 35 to 33 at android.database.sqlite.SQLiteOpenHelper.onDowngrade(SQLiteOpenHelper.java:307) at android.database.sqlite.SQLiteOpenHelper.getWritableDatabase(SQLiteOpenHelper.java:168) at org.orman.dbms.sqliteandroid.SQLiteAndroid.(SQLiteAndroid.java:39) [...]

And indeed, my db version went from 33 to 34. I saw in the orman code the following line:

---

public class SQLiteAndroid extends SQLiteOpenHelper implements Database { private static final int SQLITE_VERSION = 33; //TODO read from somewhere else ASAP

---

... and I'm suspecting that this could be causing the problem.

Right now I'm a bit at a loss here, do you see a possibility for a quick fix?

Ooops that's my bad. Can you please checkout the code, change the line that inludes 33 and run the command rake in your root? (It will require rake and therefore ruby installed, but it is the way to build our jar right now.) Let me know if you have difficulties.

thank for your quick reply. You're right that will be the fastest way to fix my problem, I will do that. It would be good if you could add a constructor with the version number to SQLiteAndroid.

Cheers, and thanks for orman. Alvi

That's a good idea. The reason it is coded that way is because I thought it was about "version of SQLite" rather than the version of the app db. Totally a misconception, sorry about that. Hope you have fixed it for yourself, I'll roll out a fix soon when I have time.

Thanks for reporting the bug.

It's fine for me now, I added the constructor and built the project without any problems.

Great, feel free to submit a pull request anytime.
