xmlns:android=“http://schemas.android.com/apk/res/android” gets added to all my layout objects causing errors

Question

At some point after updating all my ADT tools and Eclipse, all my XML files error when I open them

xmlns:android="http://schemas.android.com/apk/res/android" gets added to every layout object (root object like how I originally set it, and nested RelativeLayouts and LinearLayouts and FrameLayouts)

this causes errors in that XML file and I have to manually remove them, even with find and replace this is unnecessarily and tedious to do when I just want to look at an xml document

why is this happening, how can I prevent it

Answer 1

The problem might be with your lint errors

Right click your project goto-> Android Tools... -> choose Clear Lint Markers
