How to setup PROGUARD for Jackson JSON Processor?

Question

I am using Jackson JSON Processor for my app.Included this using

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

And my proguard configuration is.

## BEGIN -- Google Play Services proguard.txt -keep class * extends java.util.ListResourceBundle {     protected java.lang.Object[][] getContents(); } # Keep SafeParcelable value, needed for reflection. This is required to support backwards # compatibility of some classes. -keep public class com.google.android.gms.common.internal.safeparcel.SafeParcelable {     public static final *** NULL; } # Keep the names of classes/members we need for client functionality. -keepnames @com.google.android.gms.common.annotation.KeepName class * -keepclassmembernames class * {     @com.google.android.gms.common.annotation.KeepName *; } # Needed for Parcelable/SafeParcelable Creators to not get stripped -keepnames class * implements android.os.Parcelable {     public static final ** CREATOR; } ## END -- Google Play Services proguard.txt  -keepattributes Signature,RuntimeVisibleAnnotations,AnnotationDefault  -dontskipnonpubliclibraryclassmembers -dontskipnonpubliclibraryclasses -keepattributes *Annotation*. -keep class org.codehaus.jackson.**     -dontwarn twitter4j.** -dontwarn com.facebook.android.BuildConfig -dontwarn org.apache.commons.** -keep class org.apache.http.** { *; } -dontwarn org.apache.http.** -dontwarn com.nhaarman.listviewanimations.** 

However when i try to compile in debug mode i get the following error.

26207-26207/com.blah E/AndroidRuntime﹕ FATAL EXCEPTION: main     Process: com.blah, PID: 26207     java.lang.NoSuchFieldError: PUBLIC_ONLY             at java.lang.Class.getDeclaredAnnotation(Native Method)             at java.lang.Class.getAnnotation(Class.java:290)             at com.b.a.c.f.ah.<clinit>(Unknown Source)             at com.b.a.c.z.<clinit>(Unknown Source)             at com.blah.utils.c.<init>(Unknown Source)             at com.blah.main.a.a(Unknown Source)             at com.blah.main.b.a.a(Unknown Source)             at com.blah.main.b.a.onCreateView(Unknown Source) 

Working on it for a long time!Would appreciate your help!Thanks!

Answer 1

After much debugging finally found the answer my Proguard configuration is

-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 depicts the getter setter classes/class you are using to parse your response.

Also I added compile 'com.fasterxml.jackson.core:jackson-core:2.4.2' to my Gradle file which was missing previously. Now my Proguard works like a beast..;-)

Modified a litte from @goonerDroid work for me

-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.** {     *; }
