I encountered the same error message when using Eclipse 4.3.2.M20140221-1700
The solution was to update the "Google plugin for Eclipse" to version 3.6.0.v201406262229-rel-r43
Interestingly enough, the I still received the exception when altering multiple choices at the Google GWT/App properties. So the workaround was the alter one property at the time, even changing the menu and changing property would cause the exception to appear.

What can I do to solve it? I have tried many possible solutions (I tried to remove my eclipse folder and .android folder)

Further to my comment, seems post #10 in Issue 66661 that I referred to, has identical error log to yours

So it looks like you are using 22.6. Therefore just run AVD Manager from outside Eclipse until they release a 22.6.1 to fix this bug

Have you tried to remove android-sdk and install it again?

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

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?

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

It is a bug with KitKat layout renderer.

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!

How to fix the nullpointerexception that comes up in Eclipse when trying to open an Android XML file?

Since I updated the ADT plugin to v1.21 in Eclipse, I can no longer easily open any XML layout files in my Android project. As soon as, I click on the file, It throws NullPointerException. Here are the stack traces from the error log:

I can open the file if I right-click on it, and tell it t open with the Legacy Android Layout editor, but it's obviously not good solution. I tried going into Eclipse preferences, and made sure that the file associations for the XML files are set correctly.

I solved this problem by closing all open project files in the editor and restarting Eclipse.

I switch to a new workspace, then everything works fine.

Not able to open graphical editor view in android ADT 16.0.0

Went through many posts I found on the graphical editor problem I am facing. Not able to get an answer. Here is the issue
I am using Android ADT 16.0.0 and I am able to open the graphical editor but not able to see the user interface view. The app on the whole builds and works fine on the simulator. It is annooying to use only XML editor.
I installed this environment by copying the SDK, ADT plugins separately from a successful installtion. It looks as though something related to the Android Layout Editor is missing. The error thrown is

First look I guessed the layout editor files were missing. Any thougths on how to get around it??
