exception - StreamCorruptedException with Android-Java Communication -

-

i need send serialized data android device java server. don't know why, communication seems unstable. in debugger, java.io.streamcorruptedexception: thrown after start. not 1 object passing. without debugger, 10 messages passed until same exception thrown. got idea, please me:) thank you! fabian

exception:

java.io.streamcorruptedexception: invalid type code: 2f     @ java.io.objectinputstream.readobject0(unknown source)     @ java.io.objectinputstream.readobject(unknown source)     @ androidanbindung.androidverwalter.run(androidverwalter.java:114)

java-code: 

public void nachrichtenaustausch(){     port ++;     try {         serversocket = new java.net.serversocket(port);         system.out.println("warte auf 2. verbindungsaufbau...");         client = serversocket.accept();         system.out.println("verbindung 2 ist eingegangen...");         in = new objectinputstream(new objectinputstream(client.getinputstream()));         nachricht n;         // starte den regulären verkehr mit dem androidgerät         new thread(this).start();     } catch (ioexception e) {         // todo auto-generated catch block         e.printstacktrace();     }  }  @override     public void run() {         nachricht speicher;         while (true) {             try {                  speicher = (nachricht) in.readobject();                 if (speicher != null) {                     system.out.println(speicher.getname()+"..............................."+speicher.getwerte().get(0));                 }synchronized (objekliste) {                     (androidobject ao : this.objekliste) {                         if (speicher.getname().equals(ao.name)) {                             ao.abstrakter_wert = speicher.getaktuellerwert();                             if (speicher.getwerte()!=null) {                                 ao.werte = speicher.getwerte();                              }                         }                     }                 }                 thread.sleep(50);             } catch (ioexception e) {                 // todo auto-generated catch block                 e.printstacktrace();             } catch (classnotfoundexception e) {                 // todo auto-generated catch block                 e.printstacktrace();             } catch (interruptedexception e) {                 // todo auto-generated catch block                 e.printstacktrace();             }catch (exception e) {                 // todo: handle exception             }          }     }

and android thread: 

@override public void run() {     // todo auto-generated method stub       try {         while (true) {             if (!nachrichtenliste.isempty()) {                 nachricht speicher = nachrichtenliste.get(0);                 try {                     out.writeobject(speicher);                     out.flush();                     synchronized (nachrichtenliste) {                         nachrichtenliste.remove(speicher);                     }                  } catch (ioexception e) {                     e.printstacktrace();                 }             }             thread.sleep(50);             handler.post(this);         }       } catch (exception e) {         // todo: handle exception     }        }

i can imagine android , java not serialization compatible here. 1 side sends code other not expect.

i'd rather go more textual protocol (json, xml) here, serialization.
