  40. Traveler Assistant main screen Expense activity Face book and dial Expense item activity Alert dialogue Audio video The blue print of my project is given below Notification Broadcast receiver

  41. MainActivity.java, ExpenseActivity.java, ExpenseItemActivity.java, ExpenseBR.java, TimeZoneChangeBR.java, IntentActivity.java Media.java, Video.java, Notifications.java, NotificationClickedActivity.java Java files

  42. activity_main.xml expenselayout.xml addexpenselayout.xml intent_activity.xml audioplayer.xml video.xml activity_notifications.xml after_notification_is_clicked.xml strings.xml AndroidManifest.xml Xml files

  43. A xml layout file activity_main.xml was created where there are two buttons named as login button and cancel button, two text views named as user id and password and two edit text where we can write into. Then a class is to be declared as MainActivity.java with an interface onClickwhere we can write the code. The xml file is linked to the code by R.layout.xml The reference to the objects on the UI are created by findViewById. Then we have to set the listener by the method setOnClickListener After this we have to implement the interface .inside interface implementation we have to display some message by the method Toast.makeText After running this application in eclipse we can see some text are displayed when the button is clicked Designing the main screen
