Parcel Map을 사용할 수 없습니다.

Question

한 활동에서 다른 활동으로 XMPPConnection 개체를 전달하려고합니다. 저는 Parcelable을 구현하고 HashMap을 사용하여 객체를 저장하는 클래스를 작성했습니다. 의도를 만드는

class MyParcelable implements Parcelable { 


    Map val=new HashMap<String, XMPPConnection>(); 

    public XMPPConnection getConnection(String s){ 
     return (XMPPConnection) val.get(s); 
    } 

    public void setConnection(String s,XMPPConnection conn){ 
     val.put(s, conn); 
    } 

    MyParcelable() { 

     val=new HashMap<String, XMPPConnection>(); 
    } 

    public MyParcelable(Parcel in) { 
     in.readMap(val, MyParcelable.class.getClassLoader()); 
    } 

    @Override 
    public int describeContents() { 
     return 0; 
    } 

    @Override 
    public void writeToParcel(Parcel outParcel, int flags) { 

     outParcel.writeMap(val); 
    } 

    public static final Parcelable.Creator<MyParcelable> CREATOR = new Parcelable.Creator<MyParcelable>() { 

     @Override 
     public MyParcelable createFromParcel(Parcel in) { 
      return new MyParcelable(in); 
     } 

     @Override 
     public MyParcelable[] newArray(int size) { 
      return new MyParcelable[size]; 
     } 
    }; 
} 

동안, 나는이 일을 해요 : 여기

내 코드입니다

MyParcelable pr=new MyParcelable(); 
     pr.setConnection("connectionobj", connection); 
     Intent i=new Intent(TestActivity2.this,TestActivity.class); 
     i.putExtra("connection", pr); 
     startActivity(i); 

여분을 가져 오는 동안, 나는이 일을 해요 :

Bundle b = getIntent().getExtras(); 
MyParcelable object = b.getParcelable("connection"); 
this.connection=object.getConnection("connectionobj"); 

하지만 매번 예외가 발생합니다 :

outParcel.writeMap(val); 

예외 : 내가 뭘 잘못 무엇

Answer 1

사랑하는 첫 번째 줄은 명확하게 XMPPConnection이 parcelable isntance없는 문제

06-04 16:04:23.443: E/AndroidRuntime(708): java.lang.RuntimeException: Parcel: unable to marshal value org.jivesoftware.smack.XMPPConnection@44f577b8 

을 말하고있다. 만약 당신이 수업에서 하나의 물건을 parcelable 다음 다른 일을 parcelable 또는 serializable 인스턴스로 전달할 수 없을거야
