VFY: unable to resolve virtual method

Question

I am using Jackson in my android app.

I have added these two jars in my build-path:

jackson-core-asl-1.0.0.jar
jackson-mapper-asl-1.0.0.jar
         


        

Answer 1

In my case, this solution cannot work.
Check the code format of jar file is fit as JDK 1.6,
I found this issue via changing my lib code format from 1.7 to 1.6, and this issue would be solved.

1. To add a external jar on eclipse for Android Project, we can do as this :
   . Project properties -> Java Build Path -> Libraries then add those External Jar file.
   . Project properties -> Java Build Path -> Order & Export then checked those External Jar file.
   You can clean & re-build the target project to see the apk file size and test those functions in external jar.
   
   
2. To add a external jar on eclipse for Android Project, we can do as this :
   . copy the jar file to libs of android project, and done.
   
   For #1, it is easy to handle multi-projects for one libs.
   For #2, it is easy to use and no configure required.
   
   That's all.
