deserialization - Java Serialization Caused by java.lang.IllegalArgumentException: not a primitive field -


i getting below exception trace. can please suggest. doing objectinputstream.readobject(). creating problem.

exception: java.lang.runtimeexception: error occured while executing doinbackground()        @ android.os.asynctask$3.done(asynctask.java:300)        @ java.util.concurrent.futuretask.finishcompletion(futuretask.java:355)        @ java.util.concurrent.futuretask.setexception(futuretask.java:222)        @ java.util.concurrent.futuretask.run(futuretask.java:242)        @ android.os.asynctask$serialexecutor$1.run(asynctask.java:231)        @ java.util.concurrent.threadpoolexecutor.runworker(threadpoolexecutor.java:1112)        @ java.util.concurrent.threadpoolexecutor$worker.run(threadpoolexecutor.java:587)        @ java.lang.thread.run(thread.java:841) caused java.lang.illegalargumentexception: not primitive field        @ java.lang.reflect.field.setffield(field.java)        @ java.lang.reflect.field.setfloat(field.java:746)        @ java.io.objectinputstream.readfieldvalues(objectinputstream.java:1092)        @ java.io.objectinputstream.defaultreadobject(objectinputstream.java:455)        @ java.io.objectinputstream.readobjectforclass(objectinputstream.java:1347)        @ java.io.objectinputstream.readhierarchy(objectinputstream.java:1244)        @ java.io.objectinputstream.readnewobject(objectinputstream.java:1833)        @ java.io.objectinputstream.readnonprimitivecontent(objectinputstream.java:762)        @ java.io.objectinputstream.readobject(objectinputstream.java:1981)        @ java.io.objectinputstream.readobject(objectinputstream.java:1938)

a field may either of primitive or reference type. there 8 primitive types: boolean , byte , short , int , long , char , float , , double . reference type direct or indirect subclass of java.lang.object including interfaces, arrays, , enumerated types.

probably class contains reference type field not serializable, try serialize reference type fields in class.
