Android application that showing outgoing calls statistics in an interactive chart dividing by Mobile network operators at Egypt.
I used what I learned from some lessons at Google Udacity Scholarship to build this small app.
First: I used Content Provider query parameters to get only needed data instead of retrieving all of the data from the database.
Second: I used Loader and cached the data so if user choice the same period time again, the app doesn't load it again.
Incoming days I will add some enhancements to code, and if you want to adopt this app for your country feel free using the source code just edit the mobile operators' codes.
