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.

amazon web services - S3 Pre-signed POST validate file type? -

i know it's possible put limit on file size content-length-range header. possible validate file type? https://docs.aws.amazon.com/amazons3/latest/dev/httppostforms.html#policyconditions i see there content-type header, if set say, audio/mp3 allow mp3 files , return error if file not mp3? i found previous question answers mention validating file size: s3 direct upload restricting file size , type you can specify content-type @ post request. you can specify @ signature, post must done content-type: { "expiration": "2007-12-01t12:00:00.000z", "conditions": [ {"acl": "public-read" }, {"bucket": "johnsmith" }, {"content-type: "audio/mp3"} ] } creating html form (using aws signature version 4) edit: @ previous question found, checking content-type.

i wondering if instead of doing this protected override void onkeydown(keyeventargs e) { if (e.keycode == keys.a) console.writeline("the key down."); } i set bool method , this: if(keydown(keys.a)) // whatever here i've been sitting here ages trying figure out how it. can't wrap head around it. in case wondering, plan call bool inside different method, check input. since want perform action after pressing key, using keydown event enough. but in cases suppose want check if specific key down in middle of process, can use getkeystate method way: [dllimport("user32.dll", charset = charset.auto, exactspelling = true)] public static extern short getkeystate(int keycode); public const int key_pressed = 0x8000; public static bool iskeydown(keys key) { return convert.toboolean(getkeystate((int)key) & key_pressed); } you should know, each time check key state using example iskeydown(keys.a) method returns true if ke...
