Making An Android App In A Week (Currency - Simple Converter)

PRE APP TALKS

Last month i set a goal for myself. Making Android app in one week. But after i choose application context, I and my friend talk about code and UI design. We want to make a "Currency -Simple Converter" app. We looked Markets for other apps in same category, we realized nearly all of then have ugly UI, bad UX. I think a mobile app has to be simple as possible an easy to use for everyone. I always want to make simple, clean UI. So we draw some sketch and started a web search for how we can get exchange rate datas for FREE :)

After this quick search, we choose to use Yahoo. In that pre coding section, we decide to make an experiment about app's language. I wanted to add as many as possible language options and see what happens :) I hoped coding will take maximum 10 hours. (Actually it takes 11-12 hours to finish coding, bug fixing, adding theme option, UI and UX adjustments) 

All process goes like this;

FIND IDEA
THINK ABOUT IT
DESIGN UI AND UX
DESING CODE
- If you make a good design. Your coding will be take less time.
START CODING
FINISH CODING AND SEND APP TO TESTER
WAIT FOR BUGS :)

Here is final product. Do not hesitate give feedback :)

How to change position of MyLocationButton on new Map API v2 - 2

In my previuos post[1], i mention a workaround for changing buttons on Google Map which we use with google services. It is good to know they listen developers and make their products more development friendly. (I hope it goes like that way all the time and all the product lines of Google) Now we have a method for setting padding of map. It is add padding to useful area of map. We can see full screen map but with padding we can use prefered area of it. It is good for overlay action bar and other things on map view. [ 2] They write a blog and take a video about it. Read blog and watch video if you are using google map in your app :) [3] And finally, They add this method because of this issue. That means, if you find a bug or want extra feature from and api, write to google via this issue tracking system.

Using Accelerometer when Screen Off

Introduction Android Phones have a lot of built-in sensor such as gyro, proximity and accelerometer. Using Accelerometer in Android is a known thing. For listening sensors, class or service needs a SensorEventListener implementation. An Activity is only exists when you are seeing it. When phone enters standby mode, activity which was recently active frozen and restored whenever needed. While this frozen time, activity doesn’t run. Because of that it doesn’t need sensor updates. And Android stop to listen some sensors for power management. Services have this condition like classes (activity). In contrast to class, a service run every time, even when phone is in standby mode. Therefore Services needs sensor updates for some situations. But android stop to listen some sensor(accelerometer) in some different phones. There is a solution for that. This is not an exact solution but it work with a lot of phones. With a BroadcastReceiver listen   Intent. ACTION...
