SQLiteException Unknown error

Does anyone know what this means? I'm trying to start a transaction in onActivityResult() to insert a row based on the received result.

03-05 15:39:51.937: ERROR/Database(2387): Failure 21 (out of memory) on 0x0 when preparing 'BEGIN EXCLUSIVE;'.

I've had this happen to me in two situations:

  1. when SQL statements contain syntax errors
  2. when beginTransaction is called on a not-open database connection

It looks like you've run into number two. Check your syntax and make sure you open() (and don't close()) your database before you call beginTransaction.

And I think we can agree that the resulting logcat error messages are not 100% helpful.
