compatibility

I'm using the compatibility package to use Fragments with Android 2.2. When using fragments, and adding transitions between them to the backstack, I'd like to achieve the same behavior of onResume of an activity, i.e., whenever a fragment is brought to "foreground" (visible to the user) after poping out of the backstack, I'd like some kind of callback to be activated within the fragment (to perform certain changes on a shared UI resource, for instance). I saw that there is no built in callback within the fragment framework. is there s a good practice in order to achieve this? oriharel For a

I'm running Windows and the shell/OS automatically runs Python based on the registry settings when you run a program on the command line. Will this break if I install a 2.x and 3.x version of Python on the same machine? I want to play with Python 3 while still being able to run 2.x scripts on the same machine. The official solution for coexistence seems to be the Python Launcher for Windows , PEP 397 which was included in Python 3.3.0 . Installing the release dumps py.exe and pyw.exe launchers into %SYSTEMROOT% ( C:\Windows ) which is then associated with py and pyw scripts, respectively. In

I'm looking to write preferences that can be applied to both 3.0 and pre-3.0 devices. Discovering that PreferenceActivity contains deprecated methods (although these are used in the accompanying sample code), I looked at PreferenceFragement and the compatibility package to solve my woes. It appears, though, that PreferenceFragment isn't in the compatibility package. Can anyone tell me whether this was intentional? If so, can I easily target a range of devices (i.e. < 3.0 and >=3.0) or will I have to jump through hoops? If it wasn't intentionally excluded, can we expect a new release of the

I am writing a Java applet and embedding it in a web page. It used to run Mac and Windows in different browsers without problem. I was using NetBeans on the Mac to build the .jar file the applet used. For some reason or another I decided to load the project on the Windows' NetBeans - I started getting the following error on the Windows machine when accessing the web page from any browser: java.lang.ClassFormatError: Incompatible magic value 1008813135 in class file Fearing that it must have been my decision to open the project on Windows that caused this error - I tried to build from the Mac's
