Widget Preview save location
Answering my own question:The source of the application is a part of the samples in the Honeycomb sdk. By looking at the source I found out that it is saved in the "Download" folder on the sd-card. Its name is [app_name]_ori_[orientation].png. For example Gallery_ori_landscape.png.Pull it from the emulator simply by using adb pull:
adb pull sdcard/Download/[app_name]_ori_[orientation].png [remote_location]I probably asked the question too early, but I hope this will clarify the procedure for other who get this problem.
You can download emulator WidgetPreview apk and then install on you Android phone/tablet. You'll get preview image on sdcard/Download
