At the time of installation there was no sdk packages downloaded previously so when i tried downloading the sdk platforms, it shows error for Android Emulator as in screenshot. I am using proxy internet. Please suggest me the better solution. I tried taking ownership from root to myself but it didn't worked.
There is an another way to install android studio on proxy internet without any errors. First download the packages from official site, www.developer.android.com and the extract that packages in a new folder named as Android. Then create a new folder and give it a name as Sdk. At the time of installation when setup will ask you for sdk folder, then give this path of Sdk folder that you have created. make sure that in Sdk folder you have a folder named as "platforms" so that it will download all the platforms in that folder. It will work smoothly.
