In Lab2, when I was modifying and saving FirstActivity.java.bak while using NLED, the editor automatically saved a FirstActivity.java.bak in the same folder. When running 'ant debug' to compile, it generated error, explaining that unauthorized file was contained in the source folder. The way to solve this issue is to simply remove the .bak file or any other file extensions that is not the .java extension in the source directory. -- Peter

* Has anyone run into a problem where the emulator refuses to rotate (at all, never mind the layout of the running app)? I tried Ctrl+f11/f12, f11/f12, but none of them work. And I don't have a number pad on my laptop to try 7/9. --Andrew** I pressed the HOME key (number pad) on my laptop and the emulator's orientation changed from portrait to landscape. (Peter)*** Figured it out - it was already used by the xfce window manager to switch to desktop 11/12, just cleared that binding and now it works as it should == [[Working with the emulator. --AndrewAndroid Studio]] ==
* If my app has an activity (activity1) that starts another activity (activity2), what's the relationship between these two? Is it possible that == [[Web Programming Within Android will kill activity1 since activity2 is te current activity?

(ie: to delete a schedule you can just delete the account that schedule is attached to) -- Dennis ::The assignment specifies we include "validfrom" and "validto" dates. This implies that we could have several schedules for each student/teacher. eg. one for summer, another for fall, etc. However, this being our first assignment I think it would be reasonable to have exactly one timetable per student/teacher. We would then use the "validfrom" and "validto" dates to tell us when the schedule has become outdated.... John
