问题
In sdk manager i can't see any packages to install or any platforms.
I have tried running the sdk as administrator and disabling the antivirus program and firewall. And i have tried uninstalling and reinstalling it several times with no success.
I have version 18 installer_r18_windows.exe and the ADT is 18 too.
Thanks in advance Regards Tasneem

Try to update your ADT first in eclipse choose help->check all updates if it's still not working maybe you should check your SDK location in windows->preferences->android

I believe I found the answer. I'm on Windows 7, and was having this same trouble. I did the following:
- install the android sdk and latest Java 7 JDK
- find the sdk batch file "android.bat" (for me it was at C:\Program Files (x86)\Android\android-sdk\tools)
- edit this file and go to the end where it runs the final java command with the variable %java_exe%
- Add -Djava.net.preferIPv4Stack=true right after the %java_exe%
For me the line looked like this at the end:
call %java_exe% -Djava.net.preferIPv4Stack=true %REMOTE_DEBUG% -Dcom.android.sdkmanager.toolsdir="%tools_dir%" -Dcom.android.sdkmanager.workdir=%work_dir% -classpath "%jar_path%;%swt_path%\swt.jar" com.android.sdkmanager.Main %*
I then see all the packages properly show up when I run "SDK Manager" from the windows start menu. NOTE! When I run it I right click and choose "run as administrator" which I think is always a good idea so that it has permission to add files etc.
I found this solution by finding this article:

After trying some hard answers I found that it is more easier then I think:
Just open SDK-manager and click on Tools- Options and click on the Enable preview tools option. Then you will see all the packages in the SDK-manager.
