As of lately i have not being able to update / install SDKs from Android SDK Manager.

I get the following errors:

Preparing to install archives
Downloading Android SDK Platform-tools, revision 20
URL not found: C:\Program Files (x86)\Android\android-studio\sdk\temp\platform-tools_r20-windows.zip (Access is denied)

Skipping 'Android SDK Tools, revision 23'; it depends on 'Android SDK Platform-tools, revision 20' which was not installed.
Done. Nothing was installed.

I have given full right permissions on the directory that the SDK manager is installed as well as the temp directory

  • This might help, make sure that the temp folder exists in physical form. I had an issue of not able to generate temp folder. Jun 27, 2014 at 5:42
  • temp folder is there. Jun 27, 2014 at 6:51

    What OS are you running? If it's Windows make sure to Run as Administrator.

    To the close-voters: In my opinion this is on topic, since the emulator images are also updated via the SDK Manager, and questions about the emulator are on topic. Jun 27, 2014 at 10:33
  • Once I ran as Admin it worked out. But until recently I ran this without doing run as admin. Thanks for the answer. Perhaps if you put it donw as an answer I can accept it. Jun 27, 2014 at 15:12

While android-studio was already running I tried to run "android.bat" at below location by right clicking and choosing run as administrator which ran SDK manager and download worked for me.

C:\Program Files (x86)\Android\android-studio\sdk\tools\android.bat
  • Running "C:\Program Files (x86)\Android\android-sdk\tools\android.bat" as administrator on Win 10 worked for me. Thanks! Apr 17, 2016 at 0:23
  • Just want to say that it is May 2016 now, and this worked for me! I installed Visual Studio and Xamarin, then created a Xamarin.Forms app with no issues. But when I tried to create an Xamarin.Android app in Visual Studio, it asked me to update the SDK. I also installed Android Studio and the latest Java SDK, but my project still asked for a newer SDK and the above was failing. Finally found this thread and ran the .bat file as an admin. Instant success! (Well, I had to close the Windows Explorer since it had a lock on the folder location, and was blocking one of the steps) May 12, 2016 at 5:19
