Slow SDK download through Android SDK manager
I have not experienced this issue. Force or unforce HTTPS (there is an option for this under Settings), and see if this improves the quality of your connection.
I also have this problems and found a solution online and it looks like it working for now. I tried with forcing HTTP AND HTTPS and nothing really work.
So try this:
1.) Run command prompt as an administator - Windows 7 (Start->Right click on Command Prompt-> Choose "Run as Administrator") or "Start" enter CMD into search box and then right click and "Run as administrator".
2.) In Command Prompt window enter:
netshand press ENTER
3.) Then write this and hit ENTER at the end:
interface tcp set global autotuning=disabled4.) Now restart your SDK manager and try to download again!
Before doing the above, Take note of your original value in case you want to revert back:
interface tcp show global
Try disabling antivirus and enabling Force https://... sources to be fetched using http://... in Android SDK Manager's Tools-> Options....
This helped me.
