I am using Android SDK Manager revision 23.0.5. I tried to update some SDK, but got this errors. I tried a lot of times. And I try to use \"https://\" in the option but failed.
Sorry for this question, finally I find it's the network problem between Google and me. China has blocked Google. After I had used VPN, everything is OK. Thank you all for your help.
So I suggest you to check the connection between you and Google. Make sure everything is OK. Then you still have the error, you can try @Alireza Kazemi and @Hirak Chhatbar's solution.
