लोग जोड़ने के बाद NotSerializableException फेंकता है, मैं काफी एक नया Android आवेदन मैं विकासशील हूँ पर अटक हो रही है। एप्लिकेशन (कार्ड गेम) के लिए मुझे कुछ डेटा सहेजने की ज़रूरत है। मैं ऐसा करने के लिए सीरियलाइजेशन का उपयोग करता हूं।जावा अपने इंटरफेस
अब समस्या: जब मैं एक अंतरफलक मैं बारी दाताओं का ट्रैक रखने के लिए किए गए लागू करने के लिए प्रयास करते हैं, आवेदन वर्ग खेल (मुख्य गतिविधि) से एक NoSerializableException देता है। इंटरफ़ेस को हटाते समय हर चीज काम करती है।
public class Turn<T> implements Serializable{
/**
*
*/
private static final long serialVersionUID = 1L;
public interface OnTurnEndedListener<T>{
void onTurnEnded(T currentPlayer);
}
private ArrayList<T> players;
private int turnIndex;
private int rounds;
private ArrayList<OnTurnEndedListener<T>> turnEndListenerList;
public Turn() {
throw new UnsupportedOperationException("cannot init without players");
}
public Turn(ArrayList<T> players, int startingPlayerIndex) {
this.players = players;
this.turnIndex = startingPlayerIndex;
this.rounds = 0;
turnEndListenerList = new ArrayList<OnTurnEndedListener<T>>();
}
public int getRounds() {
return rounds;
}
public T next() {
turnIndex = (turnIndex + 1) % players.size();
if (turnIndex == 0) {
rounds++;
}
T retVal = players.get(turnIndex);
for (OnTurnEndedListener<T> l : turnEndListenerList) {
l.onTurnEnded(retVal);
}
return retVal;
}
public T peek() {
return players.get(turnIndex);
}
public void addOnTurnEndedListener(OnTurnEndedListener<T> l) {

}
}
जब मैं मुख्य गतिविधि (खेल) में निम्न कोड जोड़ने मैं एक अपवाद हर बार जब मैं गतिविधि को बंद मिलता है:
बारी वर्ग निम्नलिखित कोड शामिल हैं।
gameData.getTurn().addOnTurnEndedListener(new Turn.OnTurnEndedListener<Hand>() {
