Question

This error keeps showing every time I try to insert a new record in the database. I know the reason for this i think is the duplicate of the primary. I set the primary key to AUTO INCREMENT. How can I fix this error?

here’s the

}

Is there any method for this? please help

Answer 1

You’re trying to insert an item into table 1 without setting “movedate” as well, which cannot be null…I think that’s the constraint it’s bugging you about…

EDIT:
Try this method and see if it works

public long createMove(String smovename){
    ContentValues cv = new ContentValues();
    cv.put(KEY_MOVENAME, smovename);
    cv.put(KEY_MOVEDATE, "something");
    return ourDatabase.insert(DATABASE_TABLE1, null, cv);
}
