Re: [android-developers] @TreKing: How would I go about implementing a market comment response like you do.

From what I can understand: The app reads some sort of feed from the blog that is used to respond to comments. The user is then notified about the response.

Yup - that sums it up quite nicely. It's dirt simple - a poor man's RSS reader.

Steps:

1 - Post to a blog somewhere that can be subscribed via RSS. Get the url for this feed. 

2 - Start an IntentService that does the checking.

3 - Parse the xml, searching from most recent until last time you last checked (saved as SharedPreference).

4 - Saved data about each post you find that is new. (Title, URL, etc)

5 - Send notification that links the user to a given post.

6 - Profit

I have a config file that lets me set up multiple feeds, so I use the same strategy for responding to comments, notifying users about issues, or that a new version is available. Will probably create a "beta" feed soon too.

I'm looking to improve this in the future as some people have commented that the text-message style notification can be annoying, but works well enough for now.
