Android - New to Android, is this use of Application Components is correct?

so I'm extremely new to Android development. The only thing that I've actually coded is Hello World. Then I used Google App Inventor but realized that that was not what I needed. I've also read through the developer's guide. Anyway, I'm working on a project where we use various sensors (accelerometers by means of a wiimote and strain gauges converted to a digital signal through an Arduino microcontroller) and process the data on an Android tablet which will display the data for the user. Then the processed data will be uploaded to a website. Before I do anything else I need to plan out how to build this using Application Components and I wanted to make sure my general ideas are correct before I start trying to code and run into complications. So below is a list of how I think this application should user each of the application components.

Activities The user display

Services Timer

Broadcast Receivers Listen for new accelerometer data Listen for new strain gauge data

Content Providers Send the data to a website.

So开发者_JAVA技巧rry for asking such a basic question, but I find it's best to understand a tool well before I use it and I've been told that this place is noob-friendly. Thanks for your time.

Not necessarily. Broadcast receivers listen for new intents. New data won't be given in an intent unless you're the one who sends it.

Content Providers Send the data to a website.

Not really. They're for inter or cross-application sharing of data, usually from a database.

It seems you don't have a very clear understanding of any of the components of Android. Instead of just guessing, you should take a look at one of the many example android projects all over the net.
