title: Android: security issue about SQLite db
body: <p>Hello I have an android application. In my app I have a SQLite database stored on the device that should be synchronized with a MySQL database stored on the server.</p>
  
  <p>Now I have to retrieve a list of IDs. I can do it querying the SQLite database or the MySQL database. I chose to use the SQLite database because it'd be much faster and easier considering what I have to do. But now I was thinking about it and I have a question: <em>Are the android SQLite database files safe?</em> I mean is there a possibility that someone access these files and modify information inside them or are they hidden to users?</p>
  
  <p>Because if I ask information from the server I'm sure that it is safe, instead I don't know the security level of android databases.</p>
  
  <p>Let's suppose that each ID corresponds to an application ID I paid for (for example application 3 and 5). When I find a way to modify the android database and so adding also application 7 and 8 it would seem to the device that I've paid also for these applications instead I didn't and I can't use them. That's why I was thinking to query the MySQL database, because the user can't modify it, but this way it's gonna be slower. What do you think?</p>
