Question

From what I can tell, it seems like it is passing the addTask contentvalues in the wrong order, but I do not see why. The addUser method is implemented in the same way and works fine.

The error that I get and all relevant code is here. Any help is appreciated.

Answer 1

The error appears to be in your TASK_KEY_USERID as you have a space in the value. Should it perhaps be an underscore? Another note to add is that android likes your primary key column name to end in “_id”, which yours are just “id”.
