Answer 1

The easiest way is to use the SDK's SQLiteDatabase 's insert method and assume that a failed insert (the long returned is -1 rather then 1 or greater).

If you wanted more specific control/error handling then you could use the SQLiteDatabase 's insertOrThrow method to then handle the SQLiteConstraintException .
