Updating Android SDK: "A folder failed to be moved."

Question

This happens once in a while on my Windows SDK (even when I don't have any antivirus or similar programs running, execute the SDK-Manager as an administrator and so on).

I just update the tools by hand in this case. Which means close the SDK-Manager after the error and open the ANDROID_SDK\temp folder. There should be a zip named tools_R16.zip or similar (don't remember the exact name). Unzip that. You should end up with a tools folder. Copy all the files from this folder into ANDROID_SDK\tools. Overwrite when asked. And take a backup of the SDKs tools folder beforehand, just in case something explodes.

After that, start the SDK-Manager again. The tools version should be updated.

The problem seems to be that Eclipse, or even the SDK Manager itself, locks the folder. Running android.bat from the tools folder should do the trick.

If you launched the SDK Manager from Android Studio then all you need to do is close Android Studio.

I presumed the SDK Manager was a modal dialog that was part of Android Studio - not a separate program.

thanks. this is how I fixed it:

I updated the tools by hand in this case. Which means close the SDK-manager after the error and open the folder android-sdk-windows folder. Using LockHunter, unlock all programs from holding a lock on the android-sdk-windows\tools\ folder. http://lockhunter.com/?ver=&vertype=pro&sm=main_window_64

RENAME the android-sdk-windows\tools folder beforehand to tools_DELETEME There should be a zip named android-sdk-windows\temp\tools_r19-windows.zip. open that, You should see a tools folder in it. Copy that tools folder to android-sdk-windows\tools

After that, start the SDK-manager again. The tools version should be updated.
