Goto sdk\system-images and open the folder of the current API you are using (eg.android-19 folder in your case). Now you’ll find a folder named ‘default’, open it and you’ll see the folder named ‘armeabi-v7a’ or which ever system image you’ve installed. Now move the folder ‘armeabi-v7a’ to the directory sdk\system-images…i.e simply out of the ‘default’ folder.
That’s it. I had the same problem and this method worked for me. 😀
