Parcelable encountered IOException writing serializable object?

Question

I get "Parcelable encountered IOException writing serializable object" error on this code

public void onClick(View v) {
                tvResult.setText("Povezivanje s bazom u tijeku...");
                Intent i = new Intent("android.intent.action.MAINACTIVITY");

                Details details = new Details();
                details.host=etHost.getText().toString();
                details.user=etUsername.getText().toString();
                details.pass=etPass.getText().toString();
                details.database=etBaza.getText().toString();

                new GetData(tvResult).execute("");

                Bundle bundle = new Bundle();
                bundle.putSerializable("Detalji", details);
                i.putExtras(bundle);
                startActivity(i);

            }

Here is also my Details class:

public class Details implements Serializable 
    {

        private static final long serialVersionUID = 1L;
        private String host;
        private String pass;
        private String user;
        private String database;
    }

Everything is working good till startActivity(i) command, anyone have idea why?

Answer 1

in Details class have you overridden writeToParcel and readFromParcel?

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

Details needs to implement Parceleable if you want to pass complex objects via intents.

Details class needs to be in it's own file you are not implementing parcelable.

Answer 2

You have to implement Parcelable to your data class Details .

public class Details implements Serializable, Parcelable {
    private static final long serialVersionUID = 1L;
    private String host;
    private String pass;
    private String user;
    private String database;

    public Details(Parcel in){
       this.host = in.readString();
       this.pass = in.readString();
       this.user = in.readString();
       this.database = in.readString();
    }

    @Override
    public void writeToParcel(Parcel dest, int flags) {
        dest.writeString(this.host);
        dest.writeString(this.pass);
        dest.writeString(this.user);
        dest.writeString(this.database);
    }

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

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

Now I tried to write something what should work for you, but I am not 100% sure it will, so do some aditional reading from here:
