Android Eclipse Project has the following error in the console pane: “Project has no default.properties file! Edit the project properties to set one”.
There could be multiple root causes but essentially the default.properties file that stores all the settings for your Android project (such as the build target etc) has been deleted somehow.
I could not find an easy solution (if you know of one kindly inform).
1. Delete Eclipse specific files and folders (eg. “.settings”, “.project” “.metadata” etc.) from your Android project folder.
2. Open up Eclipse and ensure your Android project is removed from the Project Explorer.
3. From the Eclipse Project Explorer create a new Android project from your existing Android files.
