parcelable encountered ioexception writing serializable object…?

Question

The code

SngList.setOnItemClickListener(new OnItemClickListener() {
    public void onItemClick(AdapterView a, View v, int position, long id) {


        In         


        

Answer 1

In my case, there was a nested Delivery class inside the actual class Order (implements Serializable) which was not serialized, once Delivery class also implemented Serializable, the exception is gone. I didn't have to implement parcelable at all. Hope this helps someone!

Answer 2

I know where the problem is in your case and that is about the BitMap All you need to do is Decode your BitMap before sending into intent

Bitmap largeIcon = BitmapFactory.decodeResource(getResources(), R.drawable.thumbsup);
        ByteArrayOutputStream stream = new ByteArrayOutputStream();
        largeIcon.compress(Bitmap.CompressFormat.JPEG, 100, stream);
        byte[] byteArray = stream.toByteArray();

And then send the following Object in intent

intent.putExtras("remindermessage",object);

and if not about the Bitmap then you should look for other things which might be taking more space and decode them before sending into intent

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];
        }
    };
}

Answer 4

According to https://forums.bignerdranch.com/t/challenge-saving-state-notserializableexception-error/8018/5 you should implement or extend some class from Parcelable. In my case I had a DialogFragment with an interface MyCallback extending Serializable. In newInstance(MyCallback callback) builder I used:

Bundle args = new Bundle();
args.putSerializable(key, callback);

that led to an exception. Then I rewrote MyCallback to extend Parcelable and also added some methods to a callback when invoked this DialogFragment. At least, it doesn't crash on Home button or screen off.

Also changed to:

Bundle args = new Bundle();
args.putParcelable(key, callback);

Answer 5

To get the arraylist from another activity.

      ArrayList<SongDetails> list = new ArrayList<SongDetails>();
              list=  getIntent().getStringArrayListExtra("Data1");

To pass the arraylist to another activity.

intent.putStringArrayListExtra("Data1", Songinfo);

To split the array list:

        for(SongDetails name: list)
        {
        String yoursong= name.song;
        }

Hope this will give you some solution.
