Debug environment
For debugging to work, “adb host daemon” on PC and “adb device daemon” need to runnning. (adb means Android Debug Bridge). On the android device, allow debugging in menu Settings -> Applications -> Development.
Start Dalvik Debug Monitor by tool ddms.bat in directory C:\Program Files\Android\android-sdk\tools (exact location might vary). Press Ctrl+S or choose from the menu “screenshot”.
