After many hours of work (I do not apply Xtrem Programming...), and thousands of questions asked on this forum (thanks for the answers !), my application is now finished and available on the Android Market !
Application name : HELiOS : Help to Enjoy Light of Sun
Developper name (my other nickname) : Nekloth
Android Market URL : market://search/?q=pname:fr.nekloth.android.hinode
Price : The application is free
Aim of the application :
One of my other hobbies (except development) is photography. Then, I developped an application that lets you plan an alarm clock, by defining a time after/before a sun event (morning twilight, sunrise, sunset and evening twilight).
Then, for instance, if you want to take picture of a landscape with a beautiful light, you can schedule an alarm to be warn 1 hour before sunset, or be waked up 1:43 before sunrise (to have the time to have a breakfast !)
The sun "events" are calculated according to your GPS location and the current timezone.
Voilà, this is my work.
Any comments, remarks, suggestions of enhancements, etc... are welcome !
