java - Android ObjectInputStream readObject throws IllegalAccessException -


i trying write serialized object in onpause method file can read again file when start app time , need previous data.

this save object

try {     fileoutputstream fout = openfileoutput(logfilename, mode_private);     objectoutputstream fw = new objectoutputstream(fout);     fw.writeobject(obj);     log.d("obj", "added");     fw.close(); } catch (exception e) {     log.d("obj", "not added");     e.printstacktrace(); } return;

i can see "added" message , means object has been saved in file.

here try read saved object:

try {     fileinputstream fin = openfileinput(logfilename);     objectinputstream fread = new objectinputstream(fin);     object res = fread.readobject();     log.d("obj", "readed successfully"); } catch (exception e) {     e.printstacktrace(); }

and :

java.io.invalidclassexception: android.view.view; illegalaccessexception

on line calling "fread.readobject()". thank if please tell me why throwing following exception. in advance.
