Antonio,
Sorry that you are seeing this issue.
Can you please let us know which version of Phone Gap you are working with? Please also share the MyEclipse Build Id from Help > About section.
If you are working with PG version 3.6.3,then there is an issue with the config.xml location (by default the config.xml is placed outside of www folder). The dev team is looking into the issue with the PG team.
As a workaround, please move the config.xml file into the www folder and make sure all the image paths are relative to the www folder.
Ex : src=”res/icon/android/icon-36-ldpi.png” instead of src=”www/res/icon/android/icon-36-ldpi.png”
If you use our form based editor after moving the config.xml file into the www folder and reselect the images, it will automatically supply the right paths.
If you are working with a previous version of PG, please send us the config.xml to help us investigate further. Also share the location of the config.xml and the images relative to your project’s root folder.
Let us know how it works for you.
