Thanks, now it is obvious -

java.lang.NoSuchMethodError: org.openide.filesystems.FileUtil.getConfigFile(Ljava/lang/String;)Lorg/openide/filesystems/FileObject;
at org.netbeans.modules.android.platform.PlatformConvertor.create(PlatformConvertor.java:228)

This method got added in 6.7. I will revert the change and need to fix the build to run against 6.5.1.

Incompatibility between 6.5.1 and 6.7 is fixed now.

Still doesn't work. When clicking "Next", it switches to the next category (on the left panel), but the form itself still stays on the "Select platform type".

I'm attaching log file, as well as a screenshot.

you can see I've moved to the second step (folder), but the form is still the platform type.

Here is slightly updated version of one plugin (though it still has the same version number) that can fix the NPE). Out of curiosity - what is path to your SDK?

My SDK is at: c:\Programming\android-sdk-windows-1.5_r2

This one installs, but I don't have android option in the "New Project" option.

does it mean that the platform can be installed now?

no new project? is it persistent problem? I mean update of *platform module has to disable project module and enable it later using the dependency on a new platform support. So it might disappear after restart. if it doesn't can you attach messages.log again?

On NB 6.7, the installation overrides the Java SE project (look at the description at the bottom)

The description of Android project is wrong (result of original copy & paste from Java SE project). Fixed now.
