According to the data collected during a 14-day period ending on January 3, 2013, Android 2.3 is still active on 47.4% of devices that have accessed Google Play [5]. Therefore applications should be developed using Android 2.3 or lower. The application of this paper is developed using Android 2.2, so it is compatible with most of Android phones. The application is built using the Java programming language. The application interface is built using XML. The application is then tested on a virtual machine which emulates an Android phone.
