android – How to fix Eclipse ADT Plugin 22.3 / SDK Tools 22.3 with broken properties window?

Questions:

I recently updated the other day to the latest version of the Android ADT Plugin and SDK Tools which supports Android 4.4 KitKat. When I select a view in the graphical layout editor the properties window fields are not clickable to allow me to type into them nor can I push the 3 dots next to a field.

Using Windows 8.1 64 Bit and Eclipse Keplar. Was working fine until the update.

When looking at the Eclipse Error Log it shows

Is there any solution to this problem?

How to&Answers:

Workaround: switch to Android-18 in Graphical Layout (green Android top-right).

Answer:

It is a bug with KitKat layout renderer.

Answer:

Switching “android version to use when rendering layouts in eclipse” (green android icon on top right corner) to API 18 saved me after the update!
