Parcelable encountered IOException writing serializable object getactivity()

Question

so I am getting this in logcat:

java.lang.RuntimeException: Parcelable encountered IOException writing serializable object (name = com.resources.student_list         


        

Answer 1

Need to change all arraylist to Serializable wif in bean class :

public static class PremiumListBean  implements Serializable {
    private List<AddOnValueBean> AddOnValue;

    public List<AddOnValueBean> getAddOnValue() {
        return AddOnValue;
     }

    public void setAddOnValue(List<AddOnValueBean> AddOnValue) {
        this.AddOnValue = AddOnValue;
    }


    public static class AddOnValueBean  implements Serializable{

        @SerializedName("Premium")
        private String Premium;

        public String getPremium() {
            return Premium;
        }

        public void setPremium(String Premium) {
            this.Premium = Premium;
        }
    }
 }

Answer 2

The problem occurs when your custom class has for property some other class e.g. "Bitmap". What I made is to change the property field from "private Bitmap photo" to "private transient Bitmap photo". However the image is empty after I getIntent() in the receiver activity. Because of this I passed the custom class to the intent and also I've created a byte array from the image and pass it separatly to the intent:

selectedItem is my custom object and getPlacePhoto is his method to get image. I've already set it before and now I just get it first than convert it and pass it separatly:

 Bitmap image = selectedItem.getPlacePhoto();
 image.compress(Bitmap.CompressFormat.PNG, 100, stream);
 byte[] byteArray = stream.toByteArray();
 Intent intent = new Intent(YourPresentActivity.this, 
 TheReceiverActivity.class);
 intent.putExtra("selectedItem", selectedItem);                 
 intent.putExtra("image", byteArray);
 startActivity(intent);            

`

Then in the receiver activity I get my object and the image as byte array, decode the image and set it to my object as photo property.

 Intent intent = getIntent();
 selectedItem = (ListItem) intent.getSerializableExtra("selectedItem");
 byte[] byteArray = getIntent().getByteArrayExtra("image");
 Bitmap image = BitmapFactory.decodeByteArray(byteArray, 0, 
 byteArray.length);
 selectedItem.setPhoto(image);

Answer 3

Your OneThread Class also should implement Serializable. All the sub classes and inner sub classes must implements Serializable.

this is worked for me...

Answer 4

the Grade class must also implement Serializable

public class Grade implements Serializable {
.....your content....
}

Answer 5

Caused by: java.io.NotSerializableException: com.resources.student_list.DSLL$DNode

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

Answer 6

If you can't make DNode serializable a good solution would be to add "transient" to the variable.

Example:

public static transient DNode dNode = null;

This will ignore the variable when using Intent.putExtra(...).
