Answer 1

If you have to store small amount of data, you can use SharedPreferences in Android.

If the data that you have to store is big/complex enough, try using SQLite database.

Still need help?

UPDATE: There's a tutorial that I wrote to demonstrate how to use SQLite database. check it out here. Although it copies existing database into device's memory, but other versions of it, which create database through code can also be devised from it.

Answer 2

Android provides several options for you to save persistent application data. The solution you choose depends on your specific needs, such as whether the data should be private to your application or accessible to other applications (and the user) and how much space your data requires.

Your data storage options are the following:

Shared Preferences

Store private primitive data in key-value pairs.

Internal Storage

Store private data on the device memory.

External Storage

Store public data on the shared external storage.

SQLite Databases

Store structured data in a private database.

Network Connection

Store data on the web with your own network server.
