问题
I created Android Project but then I immediately get information that there have been errors.
Warning:(22, 12) Dependency on a support library, but the SDK installation does not have the "Extras > Android Support Repository" installed. Open the SDK manager and install it.
But I installed it, it was installed at the installation of Android Studio. I created another project and it happen again.

This is bug https://code.google.com/p/android/issues/detail?id=68834 and will be fixed in 0.5.9. In the meantime you can ignore the warning.

For me it was a very silly error and I spent the last two days trying to get around this. The path to the SDK in local.properties file was not properly escaped.
Change this:
# Location of the android SDK
sdk.dir=C:/Android/sdk
to this:
# Location of the android SDK
sdk.dir=C\:/Android/sdk
Refresh the gradle again.

When you download Android Studio you have 0.5.2 version,There is a solution is to downgrade exactly to 0.5.4 and download from here : Android Studio 0.5.4
after download the file just drag and drop in the place where you installed Android studio 0.5.2

Unfortunately, this bug appears to have resurfaced since it was last fixed. I have filed a new bug report to track it:

Please "star" the bug report if it's affecting you.
