I can see my adp2 in ddms device chooser, but cant see Dave's droid. (used to be able to before updating to usb v3!).

Objective-C to Java cross compiler

It is clear that cross compilers will not be allowed by the Apple App Store, so a developer will need to be familiar with Objective-C to create applications for the iPhone. I was wondering, is there a cross compiler that will take Objective-C application code and rebuild it into a similar Java application that can be packaged for Andro...

ListView Item Detail Screen: New or Same Activity?

I have a listview where each item correlates to an instance of an item in an array. When the user selects an item, it will bring up a 'Details' page that reads and displays other data members of the list item.

draw is being constantly called in my android map overlay

I'm trying to draw a route onto my MapView. I've extended Overlay and implemented the draw() method.

Android App Widget: Data storage

Hello everyone, I'm implementing a home screen app widget. I was wondering which is better to store/read data: SharedPreferences or a SQLite database?
