New issue 361 by perez...@gmail.com: Unable to load JacksonFactory class in
version 1.6.0-beta
http://code.google.com/p/google-api-java-client/issues/detail?id=361

Version of google-api-java-client (e.g. 1.5.0-beta)?
1.6.0-Beta

Java environment (e.g. Java 6, Android 2.3, App Engine)?
Java 6, Android 2.2

Describe the problem.
In the YouTube Sample code, when creating the final jsonFactory = new
JacksonFactory(), I get a runtime exception on the Android emulator saying
class not found, JacksonFactory. I included every possible library I could
within the dependencies including jackson-asl-core-1.9.1. Project built and
ran fine when running in regular Java environment, but I get class not
found when running on Android environment.

How would you expect it to be fixed?
Temporary work-around was to use google-api-java-client 1.5.1-beta and
the .jar's in the dependencies folder worked just fine, but they don't work
in 1.6.0-beta. I also tried using a previous version of
jackson-asl-core-1.6.7 with google java client 1.6.0-beta, no good. Maybe
there's something wrong with the set up in one of the libraries that is
causing this class to not get loaded.

JacksonFactory should be unchanged between 1.5 and 1.6. Unfortunately I
suspect it is a problem with your set up. I would need more information in
order to reproduce it, including your setup. For example, one possible bug
I've seen in the past is that old versions of the Maven Eclipse plugin
added the dependencies to the compile classpath but not the runtime
classpath.

Note that the YouTube sample is actually a command-line sample, not an
Android sample.

Comment #2 on issue 361 by nta...@gmail.com: Unable to load JacksonFactory

class in version 1.6.0-beta
http://code.google.com/p/google-api-java-client/issues/detail?id=361

This is exactly the same problem as I am having in my project. I am not
using Ant or Maven to build my Android project, just relying on Eclipse for
the time being.

The exception I was getting initially is as follows:
java.lang.NoClassDefFoundError:
com.google.api.client.json.jackson.JacksonFactory

This class is in google-http-client-1.6.0-beta.jar, which was added to
the "Referenced Libraries" section by Eclipse automatically when I added
google-api-client-1.6.0-beta.jar. I suspected that Eclipse treats it as a
compile-time dependency only (it even included a comment saying "(from
Class-Path of google-api-client-1.6.0-beta.jar)" next to the .jar file in
the Referenced Libraries section), so I added
google-http-client-1.6.0-beta.jar explicitly to the class path to make it a
runtime dependency. This resulted in another runtime exception:

java.lang.NoClassDefFoundError: org.codehaus.jackson.JsonFactory

This time I added jackson-core-asl-1.9.1.jar to the class path explicitly
(it was already there as a compile-time dependency), but then I got another
exception:

java.lang.NoClassDefFoundError: com.google.common.base.Preconditions

So I also added guava-r09.jar to the class path, but then I got the
dreaded "Conversion to Dalvik format failed with error 1", with the
following stack trace:

UNEXPECTED TOP-LEVEL EXCEPTION:
java.lang.IllegalArgumentException: already added:

Apparently, it is trying to add guava-r09.jar *twice* to the .dex file. At
this point I'm kinda stuck. Any ideas?

Same problem here. All jars have been added to my lib folder (app engine
project) and have been included as referenced libraries. Looking in the
Jar for Jackson, you can see the jSonFactory inside, but for some reason
there is a bad reference it seems inside the jar.

#6: if you are also getting the "Conversion to Dalvik format failed with
error 1" message, I managed to resolve that. Actually, the stack trace was
right, it was really trying to add
com.google.common.base.FinalizableReference twice, but not because of
guava-r09.jar. It turned out that my project also had Droid-Fu as a
dependency, and the JAR file of Droid-Fu contains Guava already, so one
copy of Guava came from google-http-client as a transitive dependency,
while the other copy of Guava was shipped with Droid-Fu. I resolved things
by re-packaging Droid-Fu and excluding Guava from it.

Has anyone manage to solve this problem? I'm having the exact same problem
with this "Could not find class 'org.codehaus.jackson.JsonFactory'" issue.
It's very frustrating as I'm completely stuck. Any help will be appreciated.

I'm also having the same issue. I'm trying to run the Google latitude
android example found here-->
http://blog.doityourselfandroid.com/2011/08/06/oauth-2-0-flow-android/

Explicitly adding the google-http-client-1.5.0-beta.jar doesn't help.
Anyone with the solution?

Solution is here:

Just add google-http-client-jackson-1.13.1-beta.jar file in libs folder of
your project.

It worked for me guys. Just add all the depencies libraries in your project
lib folder and after that just add all the libraries from project to build
path. Means select all the libraries, right click -> Build path and add to
build path.

exclude group: 'xpp3'
exclude group: 'org.apache.httpcomponents'
exclude group: 'junit'

I got the solution . It worked for me.
When you add the jar file to build path and still not resolving this issue
simply restart your eclipse or android studio.
