Android :: How To Build Calculator?
Jun 1, 2010
I'd like to build the calculator2 app supplied with android as a starting point for some mods I'm thinking about. How can I build it in eclipse? In the android source I've found only the .java files, but not the .xml like manifest, main and so on.

It helps, but still some parts are missing, i.e. R.java for example, or maybe I have done something wrong... which are the correct steps to get this program into eclipse?

I'm trying to build a calculator layout using TableLayout, but the last two rows aren't aligning with the rest of the layout. Is there something wrong with my layout XML?
What I'm trying to do would be easier to accomplish in HTML (<td> with colspan or rowspan), so should I try converting this into a WebView?
Code is as follows: (Screenshot)

I downloaded the Android 2.2 source code and try to build it. When I executed the make command, I got an error here like this build/core/java.mk:20: *** frameworks/ex/common: Invalid LOCAL_SDK_VERSION '8' Choices are: current 4 5 6 7. Stop. Then I changed the frameworks/ex/common/Android.mk to LOCAL_SDK_VERSION = 8 from LOCAL_SDK_VERSION = 7. Next place, build/core/java.mk:20: *** external/jsr305: Invalid LOCAL_SDK_VERSION '8' Choices are: current 4 5 6 7. Stop. I changed the external/jsr305/Android.mk to LOCAL_SDK_VERSION = 8 from LOCAL_SDK_VERSION = 7
Last one, build/core/java.mk:20: *** external/guava: Invalid LOCAL_SDK_VERSION '8' Choices are: current 4 5 6 7. Stop. I changed the external/guava/Android.mk to LOCAL_SDK_VERSION = 8 from LOCAL_SDK_VERSION = 7
By these changes the code started the compilation.
1. Why the error occured?
2. Changes which I did is correct or not?

Does anybody have any good tip calculator application recommendations? I've been viewing the app postings and people seem to be talking about everything except this one group of applications.

I did a few searches, and came up empty handed.I'm trying to find a decent financial calculator, similar to a BAII+ by TI.I want something that has at least a row of TVM buttons (n,i/y,npv,pv,fv,etc.) Also, it would be great to find something with a cash flow register.Is there anything like this out there? I know the official BAII+ is available to purchase for the iPhone, just wondering if something comparable is out there for my Eris (rooted, 2.1)

I have a BB Storm, but no construction calculator app is not available for the BB OS. Is there one for Android? There is a product called Inchcalc for the iPhone inchCALC iphone application and of course the real thing by Construction Master Pro with Construction Master LT - Calculated Industries. I contacted inchcalc and a few other small developers about making a BB version as there were several people on the forums asking for it. Inchcalc's response was that "we feel the Apple OS is the future and are focused on that platform..." At any rate, I'm CERTAIN that I will be moving to an Android phone. (and smashing my Storm with hammer to create an art piece--I'll call it frustration in 3D) Having a construction calculator app on the phone would mean one less device to carry around.

I looked thru lots of calculator apps but they seemed to be either tip calculators or scientific ones. I'd like on that's just like the calculator i use at my desk. I know how to figure out what the tip amount would be so don't really want one that does only that. and the one that seems to be in my Droid doesn't have a % key, unless i've missed it. I just don't see the need to have 2 different kinds of calculators taking up space on my phone.

I want to invoke the android calculator from within my app. I don't want to pass anything to it, just provide a quick launch button to it. Can anyone show me how or point me to an example of how to do this?

I'm a big Jeopardy geek, and while I use a web-based app to figure out my score as I watch, I'd love to have an app for my phone. You may all point and laugh now.

I search a better calculator for my Desire.
The stock calculator calculates incorrect,
e.g. 100-99.9=0.0999999999
The new calculator should very easy to use (and calculate correctly).
Mathematical functions to show graphically would be nice
With these many, many calculators in the market it is hard to find the right.

In the stock calculator app, when you turn your phone sideways/landscape, a few additional useful functions will show up, i.e. sine, cosine, exponent... IMO, this makes it better than the calculator app found on the market since this one shows you the entire calculation that you're typing out, rather than each individual entry when you're using several functions in a row.

So, the moral of the story is "Don't use the native calculator to do your taxes". Open the standard calculator, and enter 49990-49602.62 (a simple subtraction problem) Then push the = sign. Handy-Calc (excellent App) does not do this.

I just realized that you get a scientific calculator when rotating the phone. I plugged in a few items and noticed the sine, cosine and probably other items are WRONG!

Anyone know a simple calculator app that has M+ and M- buttons? I cannot find one driving me crazy! I found one that has a "M" button but you need to press "+" or "-" to get that functionality. i am looking for an app with dedicated buttons.

1.5 had a very functional and superior looking calculator compared to the very plain and basic functioning calculator in v2.1. I even believe it had a % key/function. Does that calculator exist in a .apk somewhere that I can put on my rooted phone? I don't want a scientific calculator but I would like a better one then the stock 2.1 I got with Damages 2.1 Rom.

I was using the calculator and set it down on the table. The screen went to landscape mode and gave more options for a scientific calculator.

The calculator app that comes with the Android OS apparently has an error. I've confirmed this error with two other Moto Droids and one HTC Android phone. In the calculator app enter:
3322.72 - 3321.92 then = and the answer is .799999
The correct answer is .80. This may seem like a minor point (.000001 error) but the answer is still wrong! Basic arithmetic operations should be a no brainer.A Verizon service rep confirmed this error on the Droid and Eris phones he had in their call center.

On my Nexus One and Incredible, you use the trackball and optical track pad, but the X doesn't have one. So how do you view calculation history on the X?

While in the stock, simple calculator, rotate to landscape mode and it converts to a featured scientific calculator.
