When I open layout editor, eclipse is giving this error:
parseSdkContent failed
Could not initialize class android.graphics.Typeface
And when I try to run project, it is giving this error :
An internal error occurred during: "Launching myapp".
java.lang.NullPointerException
解决办法：
I deleted the home/.android folder and everything is normal now.
In Windows you can find this folder in C:/Users/User/

Note: it happens when you have 2 versions of SDK and eclipse, both in the same computer (and using the same .android file), if you open on version the other will get this error.
parseSdkContent failed Could not initialize class android.graphics.Typeface
