I'm new here and new to Android development too, so I want to apologize for my ignorance.
I'm working on an application that is supposed to gather some data from an external device continuously, display the data on a chart in real-time and also store data so it's accessible at a later time as a table or as a chart. The application needs to store the data all the time, even if it's not active on the screen. Currently I have a service that starts on boot and deals with receiving the data and storing it inside a sqlite database. The service opens the database and keeps it open all the time, until it's killed. This part seems to work pretty well so far. Now, I would like to have an activity that retrieves the last 60 values from the database and plots them on a chart. I'm currently using Android Plot. I need to have a thread or something that constantly checks for database changes and redraws the chart on the screen if needed. My question is, what would be the best way to accomplish this? How to "share" the database between the service that runs all the time and an activity? I searched and answers to somewhat similar questions are all over the web. However, most people talk about how to share the database between two or more activities or between an activity and a service that is started temporarily.
