at the route :/usr/local/eclipse ,i open the folder,and execute the eclipse.however,it has a mistake.can't open.
i didn't figure it out.
solve method: drop it ,and i try use the software center's software-eclipse,however,i don't know whether its version is not matched.after a day,i uninstalled it.Then,download a new eclipse --indigo--3.7.the question of help-->install new software,always can't execute very well.
because i delete the available softwr site--dl-ssl.google.com/android/eclipse during the install ADT,the result is i can not connect it.
and, in android SDK manager,the android API levels are not shown up.Reloading does not help any more.
i have moved the android-sdk to /usr/local/ ,cd to the route,then at the terminor:
./tools/android(after you have installed jdk)
opened the android SDK manager,choose tool --> option ,chech the option:force:http ...https.
reload.(no more change)
1.9.2 done.then modify the file /etc/hosts,and add the two line before at the ipv6 setting:
