There has to be a better calculator out there, I mean CA MON! I am not looking for a scientific or some uber math calculus crazy calculator but I am looking for something that isn't so .
I mean we have a DROID! Why is this Calc so CRAPPY! Please tell me there is something out there, in the market, or even a 3rd party APK file.

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.

View 3 Replies View RelatedThe 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?
View 1 Replies View RelatedI have created what I believe is a relatively useful color picker, derived and massively extended from the ColorPickDialog example in the API Demos. If anyone would like to try it out, it is available on the Market at Applications/Tools/UberColorPicker Demo". It didn't put it in the Demo section because it isn't a demo in the sense of being a free teaser of a nonfree product, if you see my meaning. If you like it, you can download the source from http://keithwiley.com/Downloads/AndroidUberColorPickerDemo.zip. Feel free to drop it -- ready-to-go and unmodified - into your own apps (I use it for setting text color preferences in Shead Spreet)...or to hack, extend, and change it however you see fit.

I installed a couple of live wallpapers. however I cannot for the life of me get them running on the phone. It wont let me open them or anything, so not sure If i need some sort of tool or app to run these.
Secondly... any ideas where i can get the voicesearch.apk? desperate to get uber keyboard working.
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?
View 1 Replies View RelatedToday I hooked up the headphone outputs of my D.I. to my M-Audio Profire 2626 audio interface and sat down to do some semi-serious testing. I tested using 3 seconds of white noise (to test frequency response), a 20-second 20-20k sweep (to test phase coherence), and the Apples in Stereo's "Sunndal Song" (to test the ability to rock). Signal generation and MP3 conversion were done in an old version of Cool Edit Pro, and Incredible recordings and wave comparisons were done in Cubase 5. I was going to take screen caps and make a whole big thing about it, but, as an older and wiser man once said: I went into these tests being completely happy with the performance I'd got from the Incredible so far, and expecting it to pass with flying colors.
Sadly, I was just a little bit disappointed. Firstly, there appear to be major sample clock issues. "Sunndal Song" is 3:30. By the end of which there was a perceptible audio delay of roughly 35 milliseconds (the D.I. was playing back slightly more slowly than the source file). Meow, that may not sound like much, but trust me, it's an eternity. Oddly, I didn't hear any pitch-shifting occurring, and I have a really, really good ear for that kind of thing. So it's not a sample rate issue, just a clock issue. Obviously, no cell phones are going to have word clock sync or s/pdif output (and s/pdif output would have defeated the whole purpose, which was to test the DACs). I had not expected perfect sync from the Incredible;s DACs, but I had expected better results than I got.
Secondly, on every recording that I did, the Incredible appeared to be playing everything phase inverted. I switched cables and inputs on my interface, just in case either of those were faulty. Meow, this is not a huge issue, since it was phase-inverting both stereo channels at the same time. It's end-user transparent, but definitely not as it should be from a technical point of view. But what I was most concerned with was frequency response. The goal for any digital playback device is accuracy you want the music to be reproduced in the most faithful and accurate manner possible (with the highest, one might say, fidelity). In this area, the Incredible's measured results were pretty good. Here's a link to a screenshot (I don't want to risk the dreaded sidescroll and incur the wrath of the forum).
http://www.fornicorns.com/spectrum.jpg
The green lines on the bottom are the Incredible's measured audio output, the red lines on top are the source file. The Incredible does a pretty good job of both matching the subtle inflections of the original test file, and staying flat up to 20k, above which it drops off pretty quickly but that's fine, since a) that's all the frequency response that was advertised, b) no headphones can reproduce frequencies that high and c) no humans can hear them anyway. Which is why I'm at a loss to explain the very real difference in what the human ear hears from the Incredible when playing a song. I A/B'ed "Sunndal Song" repeatedly, and there are some very real and discernible differences between the Incredible's recorded playback and the source file. I used this song specifically because it's one that I had ripped from CD myself, so I know the files on the incredible and on my computer are identical. The low frequencies (bass to most of you), while it was certainly there, sounded almost compressed. Nothing was gone, but it certainly didn't seem to have the dynamic range (or "punch") that the source MP3 did. At some point, I may revisit this and do specific testing to see if there's any kind of bass compression algorithm built in to the D.I.
It would make sense for HTC to do this because loud, low frequencies with high fidelity would draw a significant amount of power from the battery. The midrange, while it didn't seem to be compressed, was definitely more pronounced and noticeable. The easiest explanation for this would be that HTC built in a mid-boost, but the white noise tests show this to be false. The high frequencies seemed to show the greatest fidelity, without any noticeable compression or attenuation, though the seemingly more pronounced mids tended to distract from them. The good news is that neither my ears nor the Profire saw anything even approaching clipping. The D.I.s audio output was actually very low, but it's designed to drive a pair of headphones, not function as a +4 dBu pro audio device. So I guess my subjective verdict is that, while the Incredible's DACs didn't perform as well as I'd hoped, it's nothing I am going to lose sleep over. It's still fine for riding my bike, plugging into the speakers at work to listen to Pandora, and everything I intended to use it for. Will it ever integrate into my live rig as a sample player? Probably not.
Im the developer of a fairly new app the Math Alarm Clock. A month ago I looked for alarm clock which was a challenge to turn off and didnt find any on the market so I developed this. Basically you tell it how hard you want the math (4 levels of difficulty) from (5*8) to [(17*19)- 16*12)]. It is smart enough to never give you stupid easy questions such as (73-73) or (1*10). Then choose how many in a row you must answer correctly from 1 to 6 to turn off the alarm. Specify a few math-free snoozes if you like to snooze a few times before entering math. Or turn the math off completely and use it as a regular alarm.
The other unique feature is the music alarm. Of the other alarm clocks I found one required you to change music into a ringtone and the other only allowed you to pick one song. This alarm clock allows you to choose an individual song or choose a random song from a specific artist or a random song from a specific album.
And for any Canadian Rogers Dream or Magic users you may have noticed other alarm clocks will completely crash your phone and require a factory reset. This has been fixed in the Math Alarm Clock and it should work with no problem on HTC based phones.
Lastly as the comments point out, I respond to feedback very fast and for the most part have requested features implemented within 24 hours.
The last few comments:
"This developer rocks! I requested a feature and it was added within hours. This is the best alarm clock for the G1 hands down!" 5/5
"Great app, developer is quick to update. Highly recommend!" 5/5
"Awesome app!" 5/5
"Amazing! The only alarm that actually wakes me up" 5/5

View 9 Replies View RelatedI need maths for my game physics and lots of them, so I use the. Math library. And guess what? I never casted so much to floats in my entire life. And i know how costly it is to use doubles on an embedded device because I read the performance optimization page in the google android sdk docs. So I am wondering if we couldn't get a Math package with functions taking and returning floats instead of the default doubles. e.g. Math.sinf Math.cosf.

View 5 Replies View RelatedI know this is more of a general programming question, but my Android friends here have always been helpful. I am trying to make an image move from one part of the screen to a position the user touches, as a constant speed. I don't know the best way to go about doing this and the way I have been trying to get to work is taxing my brain too much.
I have been using geometry to calculate slope, then using Sin * movement speed to calculate the difference in X,Y coordinates.
This is the codecode...
The problem that I'm having is the image is veering way of course when traveling in Y heavy paths. When traveling horizontally it works almost perfect.
I know there is probably an easier way though I don't know how to use a lot of things (like OpenGLES) so if your advice is to use a different method please link a tutorial for that method if you know of one.

View 3 Replies View RelatedIn the spirit of using existing, tested and stable libraries of code, I started using the Apache-Commons-Math library and its BigFraction class to perform some rational calculations for an Android app I'm writing called RationalCalc.
It works great for every task that I have thrown at it, except for one nagging problem. When dividing certain BigFraction values, I am getting incorrect results.
If I create a BigFraction with the inverse of the divisor and multiply instead, I get the same incorrect answer but perhaps that is what the library is doing internally anyway.
Does anyone know what I am doing wrong?
The division works correctly with a BigFraction of 2.5 but not 2.51, 2.49, etc...
[UPDATE]
This was indeed a bug in the apache-commons-math 2.0 libraries. The bug is fixed in v.2.1.
It is now listed in the Fixed Issues section of the bug tracker:
When multiplying two BigFraction objects with numerators larger than will fit in an java-primitive int the result of BigFraction.ZERO is incorrectly returned..attempting to reproduce the issue and setting me on the right track.

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.
