How to build app for android phone??

[Homercidal]

Here I am playing with the numbers for a brew and I suddenly have a very strong desire to have an app that can calculate how many centimeters high I need to fill a vessel X centimeters in diameter.

I have a stainless rule that I use to figure out my volumes and it works great when I can find my cheat sheet, but honestly I think it would be better to have an app that I can simply enter the two numbers in (Diameter or radius, and Volume) and it will display the necessary height.

This seems like a very simple thing to make, but I have ZERO experience writing software for a mobile device. My only real experience in programming was PASCAL and COBOL a long time ago.

Anybody got a link to a good site that can help me write this simple android app?

Geek.

Excel spreadsheet...good for a lot of useful calcs

Android development can have a fairly steep learning curve depending on your level and breadth of experience. What you're describing would be fairly trivial once you set up your development environment and ran through a few tutorials.

Start here: Installing the SDK. That will walk you through the steps needed to get your dev environment set up (the SDK, Eclipse, and Android Development Tools). Next, head to Developer Resources for sample code and tutorials.

A book may be overkill for your current purposes. If you do decide to go that route, Beginning Android Application Development is a well written one with excellent tutorials.

COBOL?!?!?!? yuck

The i used to have an app in itunes and I've played around with the ADK but haven't published anything. Not to be a Debby downer but developing in the ADK and java is drastically different from COBOL. Id start by downloading eclipse and writting a few hellow world type java apps. If you pick it up fairly quickly look to youtube and google for andriod app tutorials.

Good Luck!

It would be done already in excel, and I'll probably do it when I'm bored, but I really want to have it on my phone, which is usually on my hip when I brew, or plugged into my radio for tunes when I brew.

I'm not afraid of trying. There have been numerous attempts to do something that end in failure. At worse I can't do it and I don't have the app, which I don't have now.

Then again, maybe someone out there already has the programming tools ready to go and only has to have the idea and the formula. I thought a basic window app with a single formula would be kind of easy, relatively speaking.

Maybe I'm going the wrong way with this. maybe I need to go OLD SKOOL, and make a slide rule...

From the looks of the SDK it codes like Java, the question is how much can the Android app handle in lines of code. I have an old Java app for the automated system that has the code needed to do what is needed and more, it calculates all the volumes based on batch size, malt Lb's, and boil time, just needs a inches variable added.

Brewzor pro beta already has what you need.

I've had Brewzor for a while. Never thought to look there. I'll take a peek.

 

[Homercidal]

Yep Brewzor has it. In inches, but I can use that. AWESOME! Thanks!

 

[Just_Mike]

Not sure if it will do what you need but you can change your settings to cm and do volume calcs with it

 

[Homercidal]

Just want to send thanks again. I've been using Brewzor for a few things every brew day for a while now and obviously I just overlooked this gem. I used inches this time and later changed to metric and it seems to work excellent.

Glad it worked for you
