I am working on home screen widget, and I am facing problems when changing orientation of the phone - widget stops responding to clicks. I tried to search through groups to find solution, and closest topic was one here: http://groups.google.com/group/android-developers/browse_thread/thread/9c39f2279f8cdac3/ However, I was unable to find solution of my problem there. So, here are details of my problem:
AppWidget has two ImageViews, used to navigate through messages(forward and back). Messages are shown in TextView within a widget. When I add widget to the home screen, it works perfectly - both buttons, left and right, work ok, messages are changed when I click on buttons. Once I switch orientation of the phone, buttons are not responding anymore! So I tried to eliminate piece by piece of code, and came to strange situation:when one button is used to change message, everything works fine. But, if other button is also used to change message, application stops working after orientation change. Simply - in code provided below, when I comment out part of the code which handles ACTION_RIGTH in function onReceive, application is working properly when orientation is changed. If I uncommend it, application stops working on orientation change. Can anyone tell me what I am doing wrong here? Content of all project files is given bellow.
