Error while opening the Eclipse Android Layout Editor

Question

Since yesterday everytime I open my layout Editor in Eclipse for the Android UI I get the following exception:

Unhandled event loop exception

    ja         


        

Answer 1

I have not had that particular error, but I have had various project corruption problems related to resources. Sometimes cleaning the project and rebuilding fixes it. Sometimes I have had to revert some project files in subversion. Sometimes just relaunching eclipse fixes things. There is also a Fix Project Properties item in the Android Tools of the context menu that has helped once or twice.

Answer 2

The same thing happened to me, and I had to dig a lot before I found a solution. In my styles.xml I had an entry where the name and parent attributes were identical:

<style name="MyHeader" parent="MyHeader">
    <item name="android:background">@drawable/header_background</item>
</style>

By removing the parent attribute the layout editor finally worked again:

<style name="MyHeader">
    <item name="android:background">@drawable/header_background</item>
</style>
