Re: [android-developers] Why is ActivityGroup deprecated?
Thanks, that post didn't come up in my searches, hence I asked here.

[android-developers] Why is ActivityGroup deprecated?
Hi, I know that ActivityGroup is deprecated, and that Fragments should be used instead. My question is out of curiosity: why was it deprecated? Thanks!

Right, my question is, why are Fragments better / why were they created?

My question is out of curiosity: why was it deprecated? For exactly the reason you stated: Fragments should be used instead. The deprecated status is a clear indication to developers not to use it and use the newer, better thing instead. - TreKing http://sites.google.com/site/rezmobileapps/treking - Chicago transit tracking app for Android-powered devices -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] sending custom parcelable to another application
Hi, I'm trying to send a custom Parcelable to another application (in another process). I have a client and a remote service, as well as an abstract class (say, AbstractCustomParcelable) that I added to the Android framework itself (for research purposes). The remote service should receive an object from the client that is an instantiation of this abstract class, and then call a method on it. The problem is that if I extend AbstractCustomParcelable in the client (say, MyCustomParcelable) and then pass it to the service (by putting it in a Bundle with some other stuff and sending it via a Message), I get a ClassNotFoundError in the service: android.os.BadParcelableException: ClassNotFoundException when unmarshalling: com.my.package.Client$MyCustomParcelable I've done some searches and it appears I need to do something with the classloader, but I'm not sure where to set which classloader, and nothing I've tried has worked so far (e.g., doing setClassLoader(MyCustomParcelable.class.getClassLoader()) on the Bundle). Is there a way to make this work? Thanks in advance! Franzi -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: sending custom parcelable to another application
I figured this out, in case someone else needs this one day. In the remote service, I did: Context c = createPackageContext(com.my.package, Context.CONTEXT_IGNORE_SECURITY | Context.CONTEXT_INCLUDE_CODE); bundle.setClassLoader(c.getClassLoader()); However, what are the security implications of this (particularly the CONTEXT_IGNORE_SECURITY flag)?

[android-developers] SecurityManager
Hi, I'm wondering about the Java SecurityManager within Android. I understand that it doesn't provide the isolation/security required by Android (and that java.lang.System throws an exception if you try to setSecurityManager), but I'm wondering what the consequences of using it (in addition to existing mechanisms) would be. In particular, I'm modifying Android for some research purposes and I'd like to be able to prevent the use of reflection to access non-public methods, which can usually be done with a SecurityManager. Is there another way to do this? Thanks! Franzi -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] android.view vs android.widget
Hi, In android.view.LayoutInflater, non-fully qualified classes are expanded to android.view.ClassName -- why not android.widget.ClassName for classes that are in the widget package? (Some context, if helpful: I'm working on a research project that involves making some changes to the UI toolkit, and now I'm getting errors like java.lang.ClassNotFoundException: android.view.LinearLayout for a number of widget class while booting. If I change LayoutInflator to expand names to android.widget.ClassName it works, but that seems like a change I shouldn't be making, so I've clearly broken something else I don't know about.) Thanks!
