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

Its not getting library which it finds in debug.What do I do to fix this issue? Please help me. I couldnot release my application because of this issue. Thanks in advance.

Answer 1

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.** { 
    *; 
}
