parseSdkContent failed Could not initialize class android.graphics.Typeface

问题

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

Every time I'm getting this error and I have to restart eclipse. Is there any solution? This problem started suddenly today.

回答1:

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.

Deleting ".android" is temporarily fixing the problem with me as after sometime it begins to come again ..

Here is another cause and fix that might help .. This is happening because of existence of 2 versions of SDK in the same machine but in case you have only one version (probably it is 21) just download the SDK platform for API 20 (4.4W) as there is a problem in 21's "layoutlib.jar"). start applying the following:

Close Eclipse
Navigate to your sdk folder (something like C:\adt-bundle-windows-x86_64-20140321\sdk)
Go to platforms folder -> android-21 folder -> data folder and rename layoutlib.jar (for backup only)
Copy the same file (layoutlib.jar) from your android-20 folder to this folder "android-21"
Start Eclipse
