java.lang.NoSuchFieldError: PUBLIC_ONLY while using Box api in android in signed build

Question

I have developed android application which contains Dropbox,Google drive and Box cloud service. I tested it and everything was working. After that I signed it and I realized that debug apk size was 8.5MB whereas signed apk size was 7MB.Still I tested complete application in which everything was working except Box cloud functionality.I got below exception

I got this issue because of jackson library while compiling it with proguard, I fixed it by adding following lines in proguard file.

-keepnames class com.fasterxml.jackson.** { 
*; 
}
-keepnames interface com.fasterxml.jackson.** { 
    *; 
}

That help to bring my crash app to not crashing (but still not working probably). I use Spice and Retrofit. – John Pang Mar 29 '15 at 16:29
did you got the solution. coz I am suffering from the same. I'am using retrofit with jackson . accepted answer resolved the error and warning message but not calling the remote webservice – Ram Mandal Oct 04 '16 at 04:18
The above code prevents proguard to avoid jackson library to not to obfusicate. It seems your retrofit proguard settings is wrong. Please check retrofit official proguard settings – Abhishek Patidar Oct 04 '16 at 04:32
Thanks ! Almost all the threads I have gone through on SO for this error, I have found that the usage of fasterxml.jackson gets me into the trouble. It worked for me after I added the lines in my proguard-rules.pro that's present in android app project structure. Initially I added it in proguard-android.txt, but it didn't work out. Seems this is the only solution for this issue. – user2582651 Mar 24 '17 at 18:40
