Apps Using database for email and contact storage

[Dragonite]

Hello, Im making an application to store email templates, contact information, tags for organizing the contacts, and a feature to send the mail.

The only issue I am having is working with the databases. I have almost no experience with them, and would like advice.

I suppose what I am looking for would be the structure of the database tables. Im not sure how this works but I will list what each category includes.

Contacts:
Name
Email
Phone1
Phone2
Address
Notes

Templates:
Title/Subject
BodyText

Tags:
TagName
ContactsWithTag

Something like that. Tell me anything else you may need to know to provide help.

Unrelated but could someone tell me what is an equivalent to a comboBox?

I appreciate any help

Here is a tutorial for an SQLite example: Android SQLite Database Tutorial

And the equivalent to a Combobox in Android is a Spinner: Android spinner (drop down list) example
