My first public android app – craigslist notification

This application alert the users when new stuff is posted to craigslist. In this way they can get the best deals as soon as they are registered.

The application is totally free and doesn’t use ads either in current or future versions. There is no form of monetization associated with this application. I am using my new server that i am renting from hetzner.
The application does not require registration and does not store information about its usage on the server.

Features

• Enable the user to create notifications for certain keywords;
• Allow to have all filtering that craigslist.org has;
• Has all cities that craigslist.org has;
• Preferences menu for configuring the location and network options;
• Mark posts as favorite to read at a later time;
• The relevant posts are downloaded on the phone, so they can be read later without network;
• Faster navigation, since relevant posts are downloaded in batch;

Technical details

• It periodically checks for new posts;
• In each check it download *only* the updated data, which should be
  small after the initial download;
• If no update is available it does not download anything at all. This proves to use less bandwidth than a normal navigation app, since:
  • Only relevant data is downloaded;
  • It never download duplicated data two times;
  • It’s not like RSS feeds that it’s the phone downloading and pooling the feeds every time.
    The phone only donwload the updated data one and do it just one time.

Bandwidth usage

• For example, a download of 100 new posts takes 50kb of
  internet bandwidth.
• The daily bandwidth will depend on the number of
  notifications that you are monitoring and the number of times that
  your notifications get updated.
• To reduce bandwidth, try to be specific in your notifications.
• For example: try to use “honda civic” instead of “car”
