Just as an activity and intent receiver are both Java classes, so is a content provider. So, the big step in creating a content provider is crafting its Java class, with a base class of ContentProvider. In your subclass of ContentProvider, you are responsible for implementing six methods that, when combined, perform the services that a content provider is supposed to offer to activities wishing to create, read, update, or delete content.

Therefore, obviously there is no workaround to this particular item or risk Many consumers are comfortable, or are becoming comfortable, purchasing merchandise online by using a credit card So to keep up with the competition, your company will obviously have to accept credit cards to pay for the merchandise it sells However, you don t necessarily have to store or save a user s credit card information within the database of the system The benefit of storing the information is that when the customer returns to your site as a repeat customer, they do not have to reenter their payment or credit card data But storing this sensitive information in a database, while being convenient for the customer, presents a potential security risk.

Tapping Selection Dialog brings up a selection dialog showing the display names from the one array, as shown in Figure 21 8.

How is this sensitive information stored It is stored as plain text in the database No, this plain text could be easily read by the naked eye if someone were to intrude the system and extract the credit card information Can you store the data in a safe method The answer is yes; a best practice is that if you are going to store any sensitive information within your database, then you must encrypt the sensitive data If the sensitive information is encrypted, then if an intruder is able to see the information, they will not be able to interpret or use that information so readily Sometimes you need to store and recall a user s credit card information, such as when you charge a recurring fee for a service or product, perhaps on a monthly or quarterly basis.

SQLite is a very popular embedded database, as it combines a clean SQL interface with a very small memory footprint and decent speed. Moreover, it is public domain, so everyone can use it. Many firms (e.g., Adobe, Apple, Google, Sun, and Symbian) and open source projects (e.g., Mozilla, PHP, and Python) ship products with SQLite. For Android, SQLite is baked into the Android runtime, so every Android application can create SQLite databases. Since SQLite uses a SQL interface, it is fairly straightforward to use for people with experience in other SQL-based databases. However, its native API is not JDBC, and JDBC might be too much overhead for a memory-limited device like a phone, anyway. Hence, Android programmers have a different API to learn. The good news is that it is not that difficult. This chapter will cover the basics of SQLite use in the context of working on Android. It by no means is a thorough coverage of SQLite as a whole. If you want to learn more about SQLite and how to use it in environments other than Android, a fine book is The Definitive Guide to SQLite by Michael Owens (Apress, 2006).

A good example is the monthly subscription or even the Wine of the Month Club mentioned earlier To alleviate any concern for your customers, encrypt the data, and then assure the customers you are encrypting this sensitive data and that no one will have ready access to it This will be important to convey since there is an abundance of credit card and identity theft these days on the Internet..

Much of the sample code shown in this chapter comes from the Database/Constants application. This application presents a list of physical constants, with names and values culled from Android s SensorManager, as shown in Figure 22 1.
