After a couple of months of diving into the programming world of Android, I have finally released my first Android phone application! Tippy Tipper is a simple and open source Android Tipping Calculator. It is the result of my first experience with learning Android and I have made it an open source project so that hopefully other new Android programmers can use it as an example application to learn from. Since it is open source, it is completely free (no ads) and donations are always welcome (although I honestly do not expect many).
Some features of Tippy Tipper include:
- Enter bill via custom keypad
- Select tip by slider or three configurable buttons
- Real time calculations
- Round up or down by tip or total
- Can split the bill
- Can optionally exclude a tax rate from the bill
I still have a list of things to do with the app, so I will continue to work on it as time allows (but I am planning on starting another app soon, most likely a game). I am also open for any new feature requests and I am sure there will also be bug reports.
Supported: The app is built against the 1.6 API, but should run on any phone with Android 1.5 or greater. I primarily tested the app on my Motorola Droid, but I also tested it against other resolutions and DPIs using the Android emulator.
Why: I made this app because I did not want to get in over my head with an impossible first project while learning Android. I wanted something simple that I know I could do in my spare time. That and I thought I could make a better tipping calculator than the other ones on the Android Market. Plus, I plan on using it when I go out to eat. Dog fooding at its finest!
Download: You can find the app in the market by scanning the following QR code or you can obtain the source code from the project’s Google Code site.

I too have been studying the android os rather intensely for the past few weeks. I am ready to get started with my first app and have a good idea. Any thoughts on getting started and creating a plan. Did you use an iterative approach to build? Flow charts? Prototyping?
My first reaction is to just jump in and start coding but I realize this isn’t always the best route.
Any help is greatly appreciated as I am a new Android developer.

Hey, why does this app requires network access.? Android market shows it needs network access at the time of installation, curious to know why n/w access is required.

@Suresh I use it for error logs and analytical tracking. You can disable this in the settings under “Privacy Options”, “Enable Error Logging”: “Application reports anonymous error/event information to developer”
