Calls and Classes and Android Oh My.

I’ve written a couple of Android applications, which various folk have expressed interest in using, so here they are.  Absolutely free, tell your friends, etc. blah yadda.  Each comes with absolutely no warranty, use at your own risk, warning: choking hazard, and all that good stuff.  If you find an error, comment here to let me know and I’ll address it ASAP (which may not be all that S, be patient.)  These were written for and tested on my HTC Evo 4G.  Your screen may look slightly different if the aspect ratios are very much different.

The first Android app I wrote was Oxygen.  This allows you to enter PSI on the tank and the flow rate in LPM.  Press “Done” on your keyboard to move it out of the way, then tap the tank size you’re using.  The time remaining for the tank is calculated.  PSI is automatically reduced by 200 prior to calculation because most consider 200 PSI the “safe residual pressure” – at which point you should be looking for that new tank.  If you tap “Countdown” a counter will appear and you can put your phone away.  It’ll start buzzing when the tank nears empty.

The other “Hey-that’s-kind-of-neat-let-me-have-it” program is DripTimer.  Instead of watching the IV drip chamber and your watch, and losing count and all of that fun stuff, just run DripTimer.  Tap the upper portion of the screen each time a drop falls into the chamber.  I made the tap area quite large so you can hit it without having to look at it.  Tap  “10” if you’re using a 10-drop set, or “60” for a microdrip set.  Sorry, 15-drip-guys, I didn’t have room.  The ML/Min and ML/Hr is displayed.  Two or three drip-taps work, obviously the more actual drops you count the more accurate the calculation will be.  If you’d like to use it to count Breaths or Heartbeats (useful for tapping out neonate heart rates), tap “Breath” instead of “10” or “60”.  The display changes from “Gtts/min” to “Breaths/min” and you should ignore the ml/hour numbers, of course.  Maybe next version I’ll just blank those…

Unfortunately, WordPress does not allow the hosting of files and mine own host, alas, no longer provides this service.  The files are small enough that I feel no guilt or shame.  I was however forced to rename the files as DOC files so WordPress would allow the upload.

Windows users:  Right click either Driptimer or Oxygen and select “Save link as”.  For the file name, change the extension from “.DOC” to “.APK” (capitalization is unimportant.)

Next, you may either email the file to your Android device as an attachment, or connect the phone via USB and copy it to your SD card.

Finally, you’ll need a free file explorer program (like Astro, available in the Market) to open the file.  Android knows what to do with APK files and will install the program for you.   Since my program isn’t coming from the Market, though, you’ll need to first press [Menu button] Settings -> Applications -> Unknown Sources and make sure there’s a check mark in the box.

Have fun, leave comments if you find bugs, etc.  Again, I have other things on my plate at the moment and can’t promise features/bugfixes right away but I would appreciate any feedback.
