I am designing a simple expenses app which keeps track of expenses I do per month. The expenses have a name, amount as well as a category. One can add/delete categories at will. I am storing the categories and expenses in a database.
Right now, the way I am exposing the add categories functionality is by keeping an editText and a button called "Add category" on the "Add Expenses" activity.
So, for a user scenario like when the user does not input anything about the expenses, but just adds the category, I want it to be saved in the database.
The category save can be done immediately in the database by using a AsyncTask to call the database helper to insert a value into the table.
In the mean-time I am confused as to should I put a progressDialog so as to tell the user that I am saving something or let him populate information in the other fields.
What exactly is the UI-pattern or commonly followed strategies while saving partial information of the record into the database. Also, should I just navigate to a different activity, if adding the category into the database produces an error?
Also, a side question, should I put the "Add categories" button in a different Activity than the Add Expenses one?
