I realized that in new versions of ADT you should include the .properties file with your bank in the folder libs. The usual way to modify .classpath to point to docs / sources does not work in Eclipse with ADT, but it will.
If you have GSON in the gson-2.2.2.jarcreate file gson-2.2.2.jar.propertiesin the same folder
gson-2.2.2.jar.properties:
src=docs\\gson-2.2.2-sources.jar
doc=docs\\gson-2.2.2-javadoc.jar
docs libs javadoc.
