I have a question regarding how secure is the data in SQLite. By looking through the source code for notepad application in http://developer.android.com, there is no need for us to add password to the SQLite database. If this is the case, isn't it easier for other application to retrieve our data from the database?

When we uninstall the notepad application, will the data in our created database from notepad application be deleted as well?

Hope someone can clear up my uncertainties.
Thanks.

No, because android allows you to access your own data only.

Afaik yes, the database created by the application will be dropped when uninstalling the application.
