phantom error "error parsing XML: unbound prefix"

The error "e开发者_StackOverflow中文版rror parsing XML: unbound prefix" shows up on my main layout: main.xml when I first open Eclipse. To make the error go away, all I have to do is make a modification to the file, then undo it, then hit save (have to make a change in order to be able to save file and thus trigger the new syntax check).

My environment is:

Fedora Eclipse Platform
Version: 3.4.2
Based on build id:  20090211-1700

My target is Android API level 5.

The first time I saw the error I spent a long time trying to track down "the problem" but later realized there isn't really a problem, it's just a phantom error.

Who should I report this to?

This sounds like a bug with the ADT plugin for Eclipse. I'd first check if it's already filed; if not, go ahead and report it at b.android.com.

Once i build project with it and spent much time with this. It may also be included in the .java files (you have added by accident) line:

import android.R 

Now it thinks that we need this prefix:

xmlns:android="http://schemas.android.com/apk/res/android" 

Solve: Find and delete this line and re-build project:

// DELETE import android.R 

Add your package Resources import:

import com.johnsmith.example

I had the exact same problem and here is what I did.

• First go down to the problems tab and select the unbound prefix error
• Right click it and select delete.
• It will give you a warning message just click OK and you should be good to go.

I wouldn't recommend using this for all problems just for the phantom errors that don't seem to be caused by anything.

Hope it helps
