Add Proguard for Jackson JSON Processor about android-proguard-snippets

[goonerDroid]

@krschultz Finally found my proguard config for Jackson Proccessor.My Config is as follows:-

-keepattributes Annotation,EnclosingMethod,Signature
-keepnames class com.fasterxml.jackson.* { ; }
-dontwarn com.fasterxml.jackson.databind.
-keep class org.codehaus.* { ; }
-keepclassmembers public final enum org.codehaus.jackson.annotate.JsonAutoDetect$Visibility {
public static final org.codehaus.jackson.annotate.JsonAutoDetect$Visibility *; }
-keep public class your.class.* {
public void set_(_);
public ** get*();
}

your.class here is the getter/setter you are using to parse the response

also keep in mind to compile the same versions of Jackson Library.In my case i am using

compile 'com.fasterxml.jackson.core:jackson-databind:2.4.2'
compile 'com.fasterxml.jackson.core:jackson-annotations:2.4.2'
compile 'com.fasterxml.jackson.core:jackson-core:2.4.2'

@goonerDroid I dropped the ball on this. I reopened it at the time because although you posted the config here, we never actually put it into a file in the libraries folder. This is what we currently have:

# Proguard configuration for Jackson 2.x (fasterxml package instead of codehaus package)

-keep class com.fasterxml.jackson.databind.ObjectMapper {
    public <methods>;
    protected <methods>;
}
-keep class com.fasterxml.jackson.databind.ObjectWriter {
    public ** writeValueAsString(**);
}

@goonerDroid good point. I do actually have configuration for that in one of my projects, I'll add it to the library.

@krschultz hey added the config but i get the following crash.
E/AndroidRuntime﹕ FATAL EXCEPTION: main

Also i added the following to the proguard config:-
-dontwarn org.w3c.dom.bootstrap.DOMImplementationRegistry

Try disabling obfuscation in the proguard-project.pro file and see if it works. Obviously you wouldn't want that permanently, but I want to see if that fixes it. I'm pulling the Jackson config from a project with obfuscation turned off.

-dontobfuscate

-keepnames class com.fasterxml.jackson.** { ; }
-dontwarn com.fasterxml.jackson.databind.

Just add this and add in gradle this.

you need to add * in bracket{ } before semicolon

compile 'com.fasterxml.jackson.core:jackson-databind:2.5.3'
compile 'com.fasterxml.jackson.core:jackson-core:2.5.3'

it will work definitely.
