title: VFY: unable to resolve virtual method
body: <p>I am using Jackson in my android app.</p>
  
  <p>I have added these two jars in my build-path:</p>
  
  <pre><code>jackson-core-asl-1.0.0.jar
  jackson-mapper-asl-1.0.0.jar
  </code></pre>
  
  <p>But, I keep seeing this in my Logcat:</p>
  
  <pre><code>11-24 18:25:15.093: I/dalvikvm(28842): Could not find method org.codehaus.jackson.map.ObjectMapper.getTypeFactory, referenced from method org.springframework.http.converter.json.MappingJacksonHttpMessageConverter.getJavaType
  11-24 18:25:15.093: W/dalvikvm(28842): VFY: unable to resolve virtual method 17967: Lorg/codehaus/jackson/map/ObjectMapper;.getTypeFactory ()Lorg/codehaus/jackson/map/type/TypeFactory;
  </code></pre>
  
  <p>It's only on that method. I have searched StackOverflow on similar errors, but all of them were:</p>
  
  <ul>
  <li>Libraries wrong versions (mine are correct)</li>
  <li>Libraries not in /libs but in /lib (i have them in /libs)</li>
  </ul>
  
  <p>My Android version is 4.0.3. I am using this in combination with <code>Spring Android</code> libraries.</p>
