Hello,

When I load a default setup android application with Eclipse Galileo ("Hello Android") and start it, it works (Literally I just open a new project, name it, and click run without any changes).

Now, if I open res/layout/main.xml -- even if I don't change ANYTHING, just view, when I run the program I get errors:

[2010-04-29 17:30:07 - HelloAndroid] Waiting for HOME ('android.process.acore') to be launched...
[2010-04-29 17:30:09 - HelloAndroid] emulator-5554 disconnected! Cancelling 'com.example.helloandroid.HelloAndroid activity launch'!
[2010-04-29 17:30:19 - HelloAndroid] Error in an XML file: aborting build.
[2010-04-29 17:30:19 - HelloAndroid] res\layout\main.xml:0: ERROR Resource entry main is already defined.
[2010-04-29 17:30:19 - HelloAndroid] res\layout\main.out.xml:0: Originally defined here.
[2010-04-29 17:30:19 - HelloAndroid] C:\Users\Xblade\workspace\HelloAndroid\res\layout\main.out.xml:1: ERROR Error parsing XML: no element found
[2010-04-29 17:30:43 - HelloAndroid] Error in an XML file: aborting build.

Being extremely new to Android programming, I'm completely lost -- I understand if I changed something, but not changing anything causes this error! How am I getting this error by running the program after I simply open this file?

Also, it creates a main.out.xml file that didn't exist previously that has nothing in it ("This document is empty").

Help =P Thanks!

I followed the instructions to the letter and it worked for me. Try going through the process again, step by step. It looks like you have somehow got it looking at the e wrong XML file

Try deleting main.out.xml, if it still exists? It might have been created during the build, but it shouldn't remain after compilation...

That worked. I found out that when I click "run" looking at the xml page, it was trying to run the xml page instead of the java program. When I delete the created out.xml page and ran it looking at the java app, everything worke.d Thanks ;D

It can help to create a Run Configuration and just use that all the time rather than letting Eclipse try and build whatever you happen to be looking at. You can see your recently used configurations by clicking the dropdown next to the Run button.
