android development crusade special (part 19): a game in the weekend challenge.

Note: This is just bunch of notes for myself to keep track of how my hobby  projects develop over time.


Great  news:
  1. Doms learns Chinese hit a next milestone .10000 downloads.
  2. Doms diagnostic tools  hit a next milestone ( 10000 downloads.) soon too.
  3. Doms countries capitals flags quiz game  hit a next milestone ( 5000 downloads.)
  4. Doms learns chinese has more downloads than  Doms diagnostic tools !!!

Development news and stas:

Recently I learnt 2 new things:

  • Start activity for result, which doesn't work as well as I expected.
  • Background animation during move between activities,which add smoothness to my apps.
Nothing excited happen in my learning apart of ...  I discover a new type of Exception called  ConcurrentModificationException and solution how solved can be found here: http://pastorcmentarny.blogspot.co.uk/2013/03/how-to-solve-problem-with.html

Doms diagnostic tools


Doms diagnostic tools development going terrible slowly and it seems v2.0 release will be badly delayed.(It was plan to release around 4.4) I feel bit scared to release a new version as old one is quite stable at the moment,despite some minor bugs.


I had many features idea for my app,but to be honest  I have only a 3 big features left to do . WiFi Direct,NFC and  USB.
  • WiFi Direct is easiest to do and I am half way done.
  • USB is difficult due lack of accessory that i can plug-in and test on :/.
  • NFC is most difficult and i will abandon this feature.
I have other little things to do like:
  • I need as well update GUI to looks reasonable on Android 4.0 and above,which is boring and time consuming thing to do.
  • I fixed quite few bugs,but I have still few features that require improvements.
but I lost excitement to continue development of this app.However i do a little bits from time to time as it is my first app and it has special meaning for me.

Doms Countries Capitals Flag Quiz Game



Experimental project to help me understand, how words in description are important for better search result.


So far download rate drop badly after  my recent changes I added my ugly Feature Graphic .I 'improved' my description.
Result I lost around 33% downloads .
Some observations:
I think, my problem with description is that I try to cover too many 'key' keywords (which is country,capital,flag,quiz,game,trivia,of the world). It seems  I need narrow my most important keywords. .I will do more changes to see how they affect download rate
It seems best result i have for around 3000 characters description.
It seems my current description target to many cases
It seems suggestion of using only lowercase characters has impact on result.
