Hi,
I have some background task that is lengthy, long enough that it will
see the passing of several activities. When finished, I need to prompt
the user for some input. Is there a best-practice for keeping a
'foreground' context so I can launch an alert dialog from whichever
context is currently being shown? I can do something like this:
public class ContextReference {
private static ContextReference mInstance;
private Context mContext;
public void onActivityResume(Context context) {
mContext = context;
}
public void onActivityPause() {
mContext = null;
}
public Context getContext() {
return mContext;
}
}
then override every onResume()/onPause() pair in all activities in my
application, have them each call the corresponding methods, this
doesn't seem like a good idea though. Is there a specialized
notification class for this sort of thing? I also tried using a
context stored at startup from getApplicationContext(), but when I try
to use it with alert builder sometime into the life of my app, it
appears to not work,
Thanks
