Android app crashes after SDK-tools update version (NoClassDefFound, tool version 22)

Question

I have just updated my android SDK tools to the newly released version (tools version 22, platform tools version 17)

java.lang.NoClassDefFoundError

The .classpath file was modified. The update in added a line :

<classpathentry exported="true" kind="con" path="com.android.ide.eclipse.adt.DEPENDENCIES"/>

Before the SDK tools update, all my projects worked well !!

I corrected my problem in this way :

In the project properties (eclipse) -> java build path -> order and export make sure that all your jars in the libs folder are checked.
And "Android Tools -> Fix Project Properties"
And "Project -> Clean"

But I don't understand why! Would anybody have an explanation ?

answer your own question with the solution, you helped me fixing the annoying problem — Maragues, May 16 '13 at 15:11
Samle problem!! Even my files are generated by AndroidAnnotations. It seems like they are not added to the build path. — Basic Coder, May 16 '13 at 17:29
Do not forget to do a "Android Tools -> Fix Project Properties" then "Project -> Clean". — lopez.mikhael, May 16 '13 at 17:37
@lopez.mikhael didnt fix the issue. What did you check in the Oder and Export tab? — Basic Coder, May 16 '13 at 17:39
I'm having the exact same issue, exact same error. I've tried what @lopez.mikhael suggested and it didn't resolve my problem. I asked my question on the androiddev subreddit....http://redd.it/1egrgr — acedanger, May 16 '13 at 18:53
+1. It works for me. I have tried many other solutions this morning. — hengxin, May 29 '14 at 03:21

I fixed it by going into Java Build Path > Order and Export tab.

Click ~~everything in the list~~ "Android Private Libraries".

Then "Project -> Clean". That fixed my issue.

Just over 1.5 days on this issue, solved my problem by reading Google+.

I've just checked it carefully and we only need to check the new dependency "Android Private Libraries" (not all) and then do the "Project > Clean". Thanks @acedanger. – thelawnmowerman May 17 '13 at 08:39
You're welcome:-) ("Fix Project Properties" isn't needed either!) – thelawnmowerman May 17 '13 at 12:01

Had the same issue as StylezSoft. To clarify even further, below is my Java Build Path from Eclipse after that I solved the issue (by ticking the android-support-v4.jar library)

enter image description here

Then I cleaned the Project (Project > Clean... > OK) and everything worked fine.

I had a similar issue after the upgrade. The problem in my case was that the android-support-v4.jar library had become unchecked in the Order and Export- list. Check + rebuild solved it for me.

The error manifested itself by crashing the app when opening a dialog with a Facebook LoginButton widget on it.

Also need to make sure the Android Dependencies is checked in the Order & Export tab. Both are needed when using other library projects.

I had similar issue. But the problem was jar mismatch of "android-support-v4.jar" between Facebook SDK and my application. When I copied the same jar file from Facebook SDK to my application lib folder, the issue was resolved.

I ran into this on Android Studio. Since most of the answers here are for Eclipse, here's how to add the supportv4 library on Android Studio:

Build -> Edit Libraries and Dependencies
Click the + button
Select the support-v4 library
Click OK.

That's it.
