and problem appeared after installing android sdk tools rev. 22, android sdk build-tools , updating google play services.

whereas in error

caused by: java.lang.noclassdeffounderror: android.support.v4.util.sparsearraycompat

and noting "android.support.v4" import, javadoc isn't accessible

note: element neither has attached source nor attached javadoc , hence no javadoc found.

the problem due android support library.

hope information find solution.

right click on project -> build path -> configure build path -> order , export tab.

make sure "android private libraries" checked export.

if you've added libraries libs/ folder, remove them automatically added in "android private libraries" section.
