Helios crashes or gets massive null-pointer errors with Android SDK XML editor [message #548782]

There may be a better forum for this, I haven't found it. Please suggest
if you can. I've resisted using Helios until just now, but decided to
use it to start a new Android project.

This occurs principally when I attempt to modify an XML file using what
I suppose to be a special XML editor for Android development.

I suspect that I should modify some of the start-up memory settings in
eclipse.ini?

My environment:
Windows 7 Professional 64-bit, 8Gb RAM, Eclipse 3.6 32-bit, 32-bit JDK
located on the path C:\Users\russ\dev\eclipse\jre\jdk1.6.0_20.

C:\Users\russ\dev\eclipse\eclipse.ini contains:

-startup
plugins/org.eclipse.equinox.launcher_1.1.0.v20100507.jar
--launcher.library
plugins/org.eclipse.equinox.launcher.win32.win32.x86_1.1.0.v 20100503
-product
org.eclipse.epp.package.jee.product
--launcher.defaultAction
openFile
--launcher.XXMaxPermSize
256M
-showsplash
org.eclipse.platform
--launcher.XXMaxPermSize
256m
--launcher.defaultAction
openFile
-vmargs
-Dosgi.requiredJavaVersion=1.5
-Xms40m
-Xmx512m

Have you verified if the Android plugins are tested/supported against
Helios? It could be that they're only supported on 3.5.

Thanks, Eric. I'll look into that. I did not check into that precisely
because Lars Vogel's tutorial on Android uses Helios.

OK, well Lars knows his stuff so if he did it I'd trust that it's a good
combination ;-)

After a week of frustration I reached the conclusion that you cannot
install Android for use in Eclipse JEE, my usual mode. Instead, use the
plain Java Eclipse. My definitive installation became Eclipse Galileo
SR2 IDE for Java Developers. I added these lines to eclipse.ini, though
I probably did not have to be so generous:

-vmargs
-Xms256m
-Xmx1024m
-XX:PermSize=128m
-XX:MaxPermSize=512m

In order to distinguish this version of Eclipse from my usual JEE
development version on my task bar, I found an icon to graft onto it at
http://www.large-icons.com/stock-icons/free-large-android-ic ons.htm and
selected one that looked most like the green Android icon.

I hope this helps...
To prevent the NullPointerException when editing Android XML files in Helios , change <resources> in such XML files as "strings.xml" to

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

Strangely, the namespace is referenced in the default "main.xml"

This fix comes from A. Ravinda..., and is buried in:

Cheers for the note about "<resources xmlns:android="http://schemas.android.com/apk/res/android">"

Works a treat Smile
