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];
        }
    };
}

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);

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

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.
