Android development crusade part x/ My epic fail development: How to NOT update your aplication . history of dsdt v1.5.x

Oh shit. Oh shit. Oh shit.  OHSHIT!!!

Oh shit.

Typical fail in Dom style.
I fixed issue with flashlight, which i believe will solve problem (however i still need some code improvements,for better stability but i drop idea of implementation special case for Samsung devices as it will be bit hard for me to test).

I am aware of few issue with GPS at the moment.
- App crashed when go to "temporary out of service mode"( however.It may happen in other cases too) and it is somehow releated to ... spinner.
- in range/in use satelites give weird result. (in range is wrong).
- GPS status and status information are very messy.

I decided to tried solve problem with nasty bug that cause "IndexOutOfBoundsException" .
I surrounded all spinner code with catching IndexOutOfBoundsException and ... it still appear.
Great.
I decided to remove GPS from testing,but keep it runnable as ... beta feature,so change code and uploaded to console activated and go to work.
On way to work.i discover that ..GPS test CRASH program.

I came to work and trying to replace (reactivate previous version),but i couldn't because:
Google Play give error message:
"Error: New APK version is lower than previous APK version."
So.. i wondering what reactivate for ?
Google support responses that to solve above problem :
"You need to re-upload your app with a higher version."

I need now waiting whole day until I back to home.
I unpublished my app as is pointless for people to install crashing app and feel very upset with that.

Conclusions:

NOTE TO MYSELF:
1)
DO NOT UPLOAD APP WITHOUT DOUBLE CHECK IS EVERYTHING WORKS.
Specially in areas ,which was affected by your last changes.
Shame to have fail like that :(.

2) Do not get overexcited with upload hot fixes.Testing for correctness and stability FIRST.


v1.5.2 (bug fix release) will be release as soon as will be ready.

Fail development.....

I recently writing little app for doing backups.

Yes. I know they are plenty application that do similar job, but better.

Yes. They do lots of amazing things beyond imagination of my program.

Yes. They are bla bla bla.

But. I needed to have simply tool which will works on all OS which I am using (Windows, Linux, iOS), no law restriction, no crapware and other useful or useless stuff.

I wrote application, but without using testing tools.

However, I use this opportunity to practice my testing skills. 

However I make tiny mistake test "delete sources" starts delete  everything on whole partition (C:\). When I realise, what is going on I cancelled tests.Unfortunately  my program wiped out itself , all my projects and some important files already. For whatever reason, I had problem with recover some files.

So far, it makes my biggest fail in my software development.

Advices for future:

• Use brain, when planning do test and don't believe in what is autogenerated by IDE.
• Do backups before you do things. (quite sarcastic that,it happen during writing backup application).
• Double check your tests.  
• Do not test program in place, than can "kill" innocent and important data.

I still cannot stop laugh for mistake that I made.ROTFL
