How to check internet access
Jun 24If you call a http request, and turns out your internet access is currently down (wifi/3g not turned on), the Android OS responds with a “cannot reach host” type of message however doesn’t cause the application to crash, just stalls – for ages.
To fix this, try using a boolean value as a check for when you have internet access
Screen orientation crashes my app!
Jun 05Whilst I was developing my app, I normally had it in a portrait view, but I soon noticed when I changed the orientation to landscape, the entire app kills itself, and rerun’s the activity lifecycle from onCreate().
This causes my app to crash every time a thread was running (when it was looking for a location, or refreshing whilst a progress dialog was displayed)

ADB Drivers for HTC Desire
Apr 25If you are trying to use the USB drivers downloaded from the Android SDK, you will notice that they do not work with the HTC Desire.
I even tried to modify the inf file in the USB drivers directory in my android sdk folder, but it wasnt working.
GAHH!!!
Instead, all you need to do is install the drivers via the HTCSync install file found on the SD card (click here to download), then you’re good to go 
Make sure you have USB Debugging mode turned on (Settings -> Applications -> Development)
