My project has the run-of-the-mill HTTP calls to fetch XML files, parsing the XML files, and creating domain objects. Those objects are later used in the actions and services of the Android app. I'd like to isolate that code. I also want to write tests for it. What are some good ways of doing this? Creating an Android Library doesn't s...
I can't seem to find any documentation on the details of an Activity's run loop for Android. Apple documents the "anatomy of a run loop", and that's pretty much what I'm looking for. The Android documentation just says "Activity Is Running" in its life cycle state diagram. Obviously that's backed up by some sort of run loop. Anyone h...

In terms of usability, what are the best practices for going landscape mode with your application. I can see the need for both in some screens, but I can also see no reason for others. Providing a landscape view just because you can opens your application's UI to layout problems, shrinking views and headaches for designers. What's your...
Say I add a linear layout with top padding of 20. Does it mean that the layout is rendered with 20 pixels of padding in all phones? Or does it scale according to the height/width/density of the phone? Thanks Chris ...
Hi, The developer console provides basic install statistics but does not provide any historical data or graphs. Many sites (androidzoom.com and many more) provide a view of the Market but they seem to be very out of date and generally provide much less granular data.

I am planning on drawing a marker...
Hello! I'v been coming to drawing graphics in Android. There's a lot of sample applications out there, but one thing I always seeing is lockCanvas. Can someone explain it closer since I really don't get it and also because im think it's important to understand to future programming? An example: try { c = pa...
According to documentaion, FILL_PARENT basically lets the view take up the entire extra space. Weight also dictates how much of the extra space can be taken by the view. What is the difference? For eg: What happens when I use, new LinearLayout.LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT, 1.0f) ...
