DealDroid is small application for Android devices that continuously watches for new deals on one-deal-at-a-time sites like BonkTown, Brociety, ChainLove, Steep and Cheap, Tramdock, Whiskey Militia, Woot and associated sites, ThingFling, and SlickDeals. DealDroid runs in the background and produces Android notifications when new items become available.

You can configure how aggressively the software will search for new items, as frequent background updates and keeping the phone awake may decrease battery life a bit. Although, I have not noticed any significant battery drain on my G1 using a 2 minute check interval.

ProxySetting is a simple application for Google’s Android platform that allows users to specify an HTTP Proxy address to use when connected to a Wifi network.

At the time of writing Android only allows HTTP traffic to be directed at a proxy when using a Mobile network. It is likely that Android will be updated in the future to support the use of Proxies on Wifi networks, but for now this application aims to solve the problem.

An Android application that intercepts incoming text messages and displays them in a popup window (activity). The popup window shows the contact the message came from and their contact photo (if there is one) as well as the content of the message. Directly from the popup the user is given the option to Close the popup (marking the message read) or Reply to the message (using a system intent).

The more recent versions of SMS Popup also have a full notifications system built in – this allows a user to disable the built in messaging app notifications and use those from SMS Popup. The notifications system has additional options such as custom vibrate pattern, custom LED color and the ability to remind the user of a missed message in case they missed the notification the first time it played.
