Answer 2

Thanks to everyone.

Some, as I tried to do this. I downloaded another version of eclipse(latest indigo) and installed the ADT plug-in in it, and I could easily update the SDK

Answer 3

Try updating the ADT plugin in Eclipse first, only then this parameter will be visible.

In other words, go to "Help"> "Check for Updates in Eclipse," as soon as this is done, the Android update will be available to you.

Answer 4

I did this on Windows some time earlier, so I don’t know if it works with Linux. First I updated the Android SDK Manager, and after that I updated Android on eclipse, it worked for me. Both updates that run as an administrator.
