Error loading the SDK when Eclipse starts

I have faced the same parse sdk loading problem during eclipse startup like yours (Shown in image below)

The solution to above problem is to just delete(uninstall) the package Android Wear ARM EABI v7a system image available under Android 5.1.1 (API 22) if it's installed. (No need to uninstall whole 5.1.1 package). May be there is some eclipse bug with this package.

Finally restart eclipse to see your changes.

Edit: If the problem still exists, try removing other Android Wear package also (i.e Android Wear Intel x86 Atom System Image) as suggested by @Abhishek in comments below.

This was my error message:

Error: Error Parsing C:\Android\sdk\system-images\android-22\android-wear\armeabi-v7a\devices.xml Invalid content was found starting with element 'd:Skin'. No child element is expected at this point.

There´s a kind of problem with android Wear packages for API 22, so my solution was deleting this two packages from the API 22

The issue is still coming for API 23. To get rid from this we have to uninstall android Wear packages for both API 22 and API 23 also (till current update).
