Once again I\'ve made the mistake of updating Eclipse with the latest Android SDK/tools and have rendered it useless.
Running Eclipse on a Mac.
When I try to
Step 1) Open Eclipse and click on Run Configurations (pull down the arrow next to the Run or Debug button).
Step 2) Select "Android Application" and click "New"
Step 3) Select the "Target" tab and select "Automatic" (Click once more even it is selected and the list box below is disabled"
Step 4) Click on the "Manager..." button
Step 5) In all the "Android 4.0.X" sections, select "ARM EABI v7a System Image" checkbox
Step 6) Click the "Install X Package..." button
