Well tonight gave me a lot of insights. My Idea of modifying the Calendar App proves to be a good one, not so much because I am making huge progress on the actual app but because by trying to figure out the App I learn a heck of a lot about Android.
ONe resource that helped me getting started was this discussion on the Android-platform group
So first I learned today about the Application Fundamentals in Android. It’s a great place to start to get a general overview on how everything works. On top of that reading the Activity Class documentation hes shown to be helpful.
In my quest to get the code to work I originally just stubbed out the 3rd party classes not directly available in the Calendar app but I didn’t get beyond the first method since the GoogleLoginServiceHelper was giving me trouble. One has to understand that this Class is not part of the SDK. But you can get a Framework.jar that contains this code. Download it here from platform/frameworks/opt/com.google.android.git in the Android source repository. You only get the binary but that is enough to get you going. After having spent a few hours on LaunchActivity.java I have now moved on to MonthActivity.java
Since I am only developing in the Emulator I had to twiddle with the Resource packages a little which is biting me now since I am referencing from the wrong place. While debugging that I am reading the Documents Resources and Internationalization and Available Resource Types. After those I will also look into the API doc of Resources
Well I also found a few errors in the description on how to use Resources in Code hope those will get fixed in the documentation. All in all a very successful night.
