Android Spring Jackson Mapping: NoClassDefFoundError

i'm trying to let my android application function as a REST Client. Basically i followed this example: https://github.com/SpringSource/spring-android-samples/tree/master/spring-android-basic-auth/client/src/org/springframework/android/basicauth .

I am developing for Android 2.3 and above. I added 

spring-android-rest-template-1.0.0.RELEASE.jar
spring-android-auth-1.0.0.RELEASE.jar
spring-android-core-1.0.0.RELEASE.jar and
jackson-mini-1.9.11.jar

to my buildpath.

Anyway I always get these errors

11-26 19:01:24.461: E/dalvikvm(15994): Could not find class 'org.codehaus.jackson.map.ObjectMapper', referenced from method org.springframework.http.converter.json.MappingJacksonHttpMessageConverter.<init>
11-26 19:01:24.480: E/AndroidRuntime(15994): java.lang.RuntimeException: An error occured while executing doInBackground()
11-26 19:01:24.480: E/AndroidRuntime(15994): Caused by: java.lang.NoClassDefFoundError: org.codehaus.jackson.map.ObjectMapper

in the second line of this code:

RestTemplate restTemplate = new RestTemplate();
restTemplate.getMessageConverters().add(new MappingJacksonHttpMessageConverter());

Can anybody help me out here?

The solution to the problem was (as Selvin stated in his comment) to include the full jackson instead of the jackson mini library. Thanks again Selvin.

If you get NoClassDefFoundError during Runtime, then I suspect you did not include the .jar files to work at runtime. You have to check the checkbox for each .jar like this:
