I just started a new Android project, “WeekendStudy” to continue learning Android development and I got stumped compiling the default ‘hello weekendstudy’ compile / run. I think that I missed a step in configuration and setup, but I am at a loss to find out where. I have an AVD configured, set and launched.

When I press ‘run’, the SDK is building a file main.out.xml and then fails as this:

[2010-03-06 09:46:47 - WeekendStudy]Error in an XML file: aborting build.
[2010-03-06 09:46:48 - WeekendStudy]res/layout/main.xml:0: error: Resource entry main is already defined.

    Better fixing:
    Eclipse -> Window -> Preferences -> Run/Debug -> Launching -> Lauch Configuration

    Cross : Filter checked launch configuration types
    and Cross also : XSL (at the end of the list)
