java.lang.nullpointerexception [message #549069]

Forgive me. I am a little knew. Just installed the Android SDK and Eclipse Helios setup and am going through some of the Android tutorials. I successfully created the HelloWorld app but now I am trying to edit the XML code. I am trying to edit the string.xml file in value. When I change one character in the file I get a message box that says "Multiple problems have occurred. java.lang.nullpointerexception: An error has occurred. See log for more details."

Can some one explain what this is and what a possible solution may be.

Thanks

I actually figured it out. The default editor it was using was no good. Instead I have to right click on the file and go to: Open With<Androind XML Resource Editor. And now it works fine.

I complained about this a few days ago. The Android XML Resource Editor
is the one that comes up when I double-click the file. I had the same
result as you--having to dismiss a null-pointer error alert between
every keystroke. Using the more graphic approach to modifying my file
hardly worked at (which is why I went to the text editor method).

I wondered if I need to modify my start-up memory amounts.

The Android Layout Editor did not suffer from this problem.

This is disconcerting as Eclipse is supposed to be the primo Android
development environment.

See the topic in this forum titled "Helios crashes or gets massive
null-pointer errors with Android SDK XML editor"

add xml namespace to the resource tag. This will make the nullpointerexception go away.

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