my xml layout file:

desktop widgets have limited set of allowed parts. restrictions necessary due potential security issues of allowing arbitrary code execution in home screen.

here's relevant part of appwidget docs:

a remoteviews object (and, consequently, app widget) can support following layout classes:

framelayout

linearlayout

relativelayout

gridlayout

and following widget classes:

analogclock

button

chronometer

imagebutton

imageview

progressbar

textview

viewflipper

listview

gridview

stackview

adapterviewflipper

descendants of these classes not supported.
