Today, I tried to develop my very first app for Windows Phone 8 (WP 8). I found a digital version of WP8 Development Internals and started reading. My goal was to develop an application that schedules the silence mode. If I had finished the application, I would have a scheduling mechanism that automatically sets my phone to silent mode whenever I wanted. Yet I realized my doom about 6 pm.
First of all, except reminders and alarms, there is no scheduling mechanism that you can set for a specified time. There are two background task models, yet none of them provides such a mechanism. Secondly, for security reasons, apps cannot change several system settings. And volume control is one of those settings that no third party app can control.
I named my app as “Code of Silence”, for 3 apparent reasons. It is my very first “Code” for WP8. Secondly, “Code of Silence” is a very interesting concept in real life. And last of all, Chuck Norris has a movie with the same name.
