java - every time I change my widget xml, I get runtime error in eclipse -

-

i try edit android widget xml.

everytime change 1 property (drawable, gravity...)

the layout marked error

build runs ok, application doesn't run.

eclipse says there errors, see no in error window/problem/log-catenter image description here

unexpected namespace prefix "xmlns" found tag linearlayout

enter image description here

xmlns means xml namespace.

i think attribute should on first element of xml file, , that's why error
