SQLite simultaneous reading and writing

Question

I\'ve read a lot of topics, but can\'t figure out answer for question: is it possible to read and write simultaneous?

I have background thread that updates some data

Answer 1

It is not possible to read & write simultaneously. However, if you have your SQLite database classes set up correctly (single instance of your DB & helper classes), different threads should be able to grab the DB connection synchronously so that there is not any noticeable lag.

It also sounds like you're trying to do backend work (write to the db) with your UI thread. You should not be doing this. Create an AsyncTask to handle this instead of having your UI thread handle it.

Refer to the SQLiteOpenHelper documentation. Here's a previous post that talks about this as well: What are the best practices for SQLite on Android?
