Parcelable Encountered Ioexception Writing Serializable Object Getactivity()

Parcelable encountered IOException writing serializable object getactivity()

Your DSLL class appears to have a DNode static inner class, and DNode is not Serializable.

Java android ava.lang.RuntimeException: Parcelable encountered IOException writing serializable object

Try replacing Serializable implementation with Parcelable in Vals & RawBean classes

Replace getSerializableExtra with getParcelableExtra in *onActivityResult**

Vals.java

 public class Vals implements Serializable, Parcelable {
    public ArrayList<RowBean> data;

    public Vals(ArrayList<RowBean> data) {
        this.data = data;
    }

    protected Vals(Parcel in) {
        if (in.readByte() == 0x01) {
            data = new ArrayList<RowBean>();
            in.readList(data, RowBean.class.getClassLoader());
        } else {
            data = null;
        }
    }

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

    @Override
    public void writeToParcel(Parcel dest, int flags) {
        if (data == null) {
            dest.writeByte((byte) (0x00));
        } else {
            dest.writeByte((byte) (0x01));
            dest.writeList(data);
        }
    }

    @SuppressWarnings("unused")
    public static final Parcelable.Creator<Vals> CREATOR = new Parcelable.Creator<Vals>() {
        @Override
        public Vals createFromParcel(Parcel in) {
            return new Vals(in);
        }

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

RawBean.java

public class RowBean implements Serializable, Parcelable {

    public String title;
    public boolean selected;

    public RowBean(){
    }

    public boolean isSelected() {
        return selected;
    }

    public void setSelected(boolean selected) {
        this.selected = selected;
    }

    public RowBean(boolean selected, String title) {
        this.selected = selected;
        this.title = title;
    }

    public String getTitle() {
        return title;
    }

    public void setTitle(String title) {
        this.title = title;
    }

    protected RowBean(Parcel in) {
        title = in.readString();
        selected = in.readByte() != 0x00;
    }

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

    @Override
    public void writeToParcel(Parcel dest, int flags) {
        dest.writeString(title);
        dest.writeByte((byte) (selected ? 0x01 : 0x00));
    }

    @SuppressWarnings("unused")
    public static final Parcelable.Creator<RowBean> CREATOR = new Parcelable.Creator<RowBean>() {
        @Override
        public RowBean createFromParcel(Parcel in) {
            return new RowBean(in);
        }

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

parcelable encountered ioexception writing serializable object.........?

Ok i implemented part of it for you. You have to add all the other properties of your SongDetails class:

MainActivity.java:

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    SongDetails Songinfo1 = new SongDetails();
    Songinfo1.setSong("song1");

    SongDetails Songinfo2 = new SongDetails();
    Songinfo2.setSong("song2");

    ArrayList<SongDetails> list = new ArrayList<SongDetails>();
    list.add(Songinfo1);
    list.add(Songinfo2);

    Intent intent = new Intent(this, SecondActivity.class);
    intent.putParcelableArrayListExtra("Data1", list);
    intent.putExtra("Data2", 1);
    startActivity(intent);

}

In the activity in which you are retrieving the songs, use this:

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_asdf);

    ArrayList<SongDetails> songs = getIntent().getParcelableArrayListExtra("Data1");

    for(SongDetails songDetails : songs) {
        Log.i("", songDetails.getSong());
    }
}

Your SongDetails class should look like this:

SongDetails:

public class SongDetails implements Parcelable {
    Bitmap icon;
    String song;
    String Artist;
    String Album;
    String Path;
    int icLauncher;

    public SongDetails() {
    }

    public SongDetails(Parcel in) {
        String[] data = new String[1];
        in.readStringArray(data);
        this.song = data[0];
    }

    public String getSong() {
        return song;
    }

    public void setSong(String song) {
        this.song = song;
    }

    public String getArtist() {
        return Artist;
    }

    public void setArtist(String Artist) {
        this.Artist = Artist;
    }

    public Bitmap getIcon() {
        return icon;
    }

    public void setIcon(Bitmap bitmap) {
        this.icon = bitmap;
    }

    public String getPath2() {
        return Path;
    }

    public void setPath2(String Path) {
        this.Path = Path;
    }

    public String getAlbum() {
        return Album;
    }

    public void setAlbum(String Album) {
        this.Album = Album;
    }

    public void setIcon(int icLauncher) {
        this.icLauncher = icLauncher;
    }

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

    @Override
    public void writeToParcel(Parcel dest, int flags) {
        dest.writeStringArray(new String[] { this.song });
    }

    public static final Parcelable.Creator CREATOR = new Parcelable.Creator() {
        public SongDetails createFromParcel(Parcel in) {
            return new SongDetails(in);
        }

        public SongDetails[] newArray(int size) {
            return new SongDetails[size];
        }
    };
}

Parcelable encountered IOException writing serializable object when I don't serialize anything

So I have an answer to the problem. This answers has base on the answers given on this post:

Why is it possible to pass a Drawable trough a Bundle from one Activity to a Fragment?

The answer is simple, as when passing objects as arguments to a Fragment will not cause it to be Marshled. This means it wouldn't be Serialized/Deserialized unless the Fragment is destroyed. And in this case he is destroyed when I try to start a new Activity. I tought Drawable was serializable cause I wasn't getting any errors while I was inside the Fragment, little did I know I was dealing with the same object (reference) itself.

Parcelable encountered IOException writing serializable object in Fragment

Your VaccineDetailsModel must implements as Serializable

java.lang.RuntimeException: Parcelable encountered IOException writing serializable object (name = com.jaapp.treeview.InMemoryTreeStateManager)

The root cause of your problem is

Caused by: java.io.NotSerializableException: com.jaapp.dto.QuestionsDto

which clearly indicates that your class is not serializable.
Make sure your class implements the Serializable marker interface.
