public String getAction();
public String getType();

Not able to access getter method of POJO inside OnNext() in rxretrofit

I am trying to access getter property of the pojo received in the response, but there is no such option.so is there any other way, I can do that?
The code for that call is as below:
results.subscribeOn(Schedulers.io()).observeOn(AndroidSchedulers.mainThread())

Now Basically I want to acess someting like response.getData().... But there is no such option.

Possibly data not accessible, because it is private. Try to crete getter method.
public class GenericResponse<T> {
#JsonProperty("status")
private String status;
#JsonProperty("message")
private String message;
#JsonProperty("data")
private T data;
public T getData() {
return data;
}
}

Pass ArrayList of Parcelable objects throws error

I have an object with a couple of Strings, one int and another object which has 4 inner objects. All of them implementing Parcelable. In order to generate the boilerplate code, I used Parcelable plugin from Android studio.
Even though all the objects are parcelable, I'm getting the following error: android.os.BadParcelableException: ClassNotFoundException when unmarshalling: AlbumTrackResponse
Here's how the POJOs look like:
Main object:
public class AlbumTrackResponse implements Parcelable {
private String id;
private String albumId;
private String position;
private String title;
private int rate;
private AllServices services;
public AllServices getServices() {
return services;
}
public void setServices(AllServices services) {
this.services = services;
}
public String getId() {
return id;
}
public void setId(String id) {
this.id = id;
}
public String getAlbumId() {
return albumId;
}
public void setAlbumId(String albumId) {
this.albumId = albumId;
}
public String getPosition() {
return position;
}
public void setPosition(String position) {
this.position = position;
}
public String getTitle() {
return title;
}
public void setTitle(String title) {
this.title = title;
}
public int getRate() {
return rate;
}
public void setRate(int rate) {
this.rate = rate;
}
protected AlbumTrackResponse(Parcel in) {
id = in.readString();
albumId = in.readString();
position = in.readString();
title = in.readString();
rate = in.readInt();
services = (AllServices) in.readValue(AllServices.class.getClassLoader());
}
#Override
public int describeContents() {
return 0;
}
#Override
public void writeToParcel(Parcel dest, int flags) {
dest.writeString(id);
dest.writeString(albumId);
dest.writeString(position);
dest.writeString(title);
dest.writeInt(rate);
dest.writeValue(services);
}
#SuppressWarnings("unused")
public static final Parcelable.Creator<AlbumTrackResponse> CREATOR = new Parcelable.Creator<AlbumTrackResponse>() {

}
Inner object with 4 objects
public class AllServices implements Parcelable {
private GigRevService gigrev;
private AppleService apple;
private GoogleService google;
private SpotifyService spotify;
protected AllServices(Parcel in) {
gigrev = (GigRevService) in.readValue(GigRevService.class.getClassLoader());
apple = (AppleService) in.readValue(AppleService.class.getClassLoader());
google = (GoogleService) in.readValue(GoogleService.class.getClassLoader());
spotify = (SpotifyService) in.readValue(SpotifyService.class.getClassLoader());
}
#Override

}

}

}
public void setGoogle(GoogleService google) {
this.google = google;
}
public SpotifyService getSpotify() {

}
public void setSpotify(SpotifyService spotify) {
this.spotify = spotify;
}
#Override

}
#Override

return new AllServices[size];
}
};
}
The inner objects from here contain just string items.
Here's how I pass the ArrayList to the bundle:
bundle.putParcelableArrayList(MediaPlayerService.TRACK_LIST, trackList);
I'm passing the items from an Activity to a Service. Any ideas why I'm getting this error?
EDIT: Implementation of service classes
public class GoogleService implements Parcelable {
private String name;
private String uri;
public String getUri() {
return uri;
}
public void setUri(String uri) {
this.uri = uri;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
protected GoogleService(Parcel in) {
name = in.readString();
uri = in.readString();
}
#Override
public int describeContents() {
return 0;
}
#Override
public void writeToParcel(Parcel dest, int flags) {
dest.writeString(name);
dest.writeString(uri);
}
#SuppressWarnings("unused")
public static final Parcelable.Creator<GoogleService> CREATOR = new Parcelable.Creator<GoogleService>() {
#Override
public GoogleService createFromParcel(Parcel in) {
return new GoogleService(in);
}
#Override
public GoogleService[] newArray(int size) {
return new GoogleService[size];
}
};
}

This looks extremly strange
this.services = in.readParcelable(getClass().getClassLoader());
You are pointing out to the wrong class loader. You have to use it like this
this.services = (AllServices)in.readParcelable(AllServices.class.getClassLoader());
Besides that, I am always using this site http://www.parcelabler.com/ to quickly generate my Parceables. Or you could use it like this
services = (AllServices) in.readValue(AllServices.class.getClassLoader());

Here:
protected AllServices(Parcel in) { this.gigrev = in.readParcelable(getClass().getClassLoader());
this.apple = in.readParcelable(getClass().getClassLoader());
this.google = in.readParcelable(getClass().getClassLoader());
this.spotify = in.readParcelable(getClass().getClassLoader()); }
Replace it with
protected AllServices(Parcel in) { this.gigrev = in.readParcelable(GigRevService.class.getClassLoader());
this.apple = in.readParcelable(AppleService.class.getClassLoader());
this.google = in.readParcelable(GoogleService.class.getClassLoader());
this.spotify = in.readParcelable(SpotifyService.class.getClassLoader()); }
And replace:
this.services = in.readParcelable(getClass().getClassLoader());
With:
this.services = in.readParcelable(AllServices.class.getClassLoader());
Also can you show the GoogleService etc classes? Each inner object's class must have a Parcelable creator also and implement the Parcelable interface as well.

Put two parcelable inside same intent

Folks, I'm getting mad with parcelables.
Here goes, I have these lines:
Intent i = new Intent(context, PaymentDetailsActivity.class);
i.putExtra(ConstantsUtils.PARAM_INTENT_ORDER_DETAILS, responseOrderInfoApiModel);
i.putExtra(ConstantsUtils.PARAM_INTENT_PAYMENT_INFO, paymentInfoViewModel);
startActivity(i);
and here I receive my parcelables:
Intent receivedIntent = getIntent();
responseOrderInfoApiModel = receivedIntent.getParcelableExtra(ConstantsUtils.PARAM_INTENT_ORDER_DETAILS);
paymentInfoViewModel = receivedIntent.getParcelableExtra(ConstantsUtils.PARAM_INTENT_PAYMENT_INFO);
The point is, responseOrderInfoApiModel is receiving a null, but it shouldn't, however if I comment the line:
i.putExtra(ConstantsUtils.PARAM_INTENT_PAYMENT_INFO, paymentInfoViewModel);
My responseOrderInfoApiModel receive the correct value.
Here goes my parcelables:
ResponseOrderInfoApiModel -
public class ResponseOrderInfoApiModel implements Parcelable{
private String cardNumber;
private double total;
private ArrayList<ResponseOrderItemApiModel> listItem;
public ResponseOrderInfoApiModel() {

public ResponseOrderInfoApiModel(Parcel source) {

PaymentInfoViewModel -
public class PaymentInfoViewModel implements Parcelable {

}
public long getIdCardPayment() {

}
public void setIdCardPayment(long idCardPayment) {

}

Try using bundle and put your data in bundle and then put bundle in to intent. Once i had such a funny problem and this method solved my problem.

I have read a lot of codes, and I have do it a lot of times, but I don't know the mistake!!
very thanks!!!

You must retrieve data as the way (data-type & order) you added. So this line can cause the issue:
dest.writeLong(this.id);
Replace that with:
dest.writeInt(this.id);

Android Parceable issue

I am currently trying to pass a parceablearraylist from mylogin activity to my main activity but getting a

Been trying to fix it for the pass day and getting no where all I know is that person parceable object in the challenge object are always null but they are not when I put them in the bundle.
Appreciate any input.

Those Integer type could be null or an int, you need to handle that situation properly.
For example I have utility functions like this :
static public Integer readInteger(Parcel in){
if(in.readInt() == 1){
return in.readInt();
}else{
return null;
}
}
static public void writeInteger(Integer value, Parcel out){
if(value != null){
out.writeInt(1);
out.writeInt(value);
}else{
out.writeInt(0);
}
}

First thing in the class Challenge you use Integer attributes and you parce "int" those are 2 diferents things.
Exemple of how i do things myself :
public Podcast(Parcel parcel) {
id = parcel.readLong();
title = parcel.readString();
subtitle = parcel.readString();
summary = parcel.readString();
duration = parcel.readString();
author = parcel.readString();
date = parcel.readString();
mp3 = parcel.readString();
podcastCategoryId = parcel.readLong();
}
#Override
public int describeContents() {
// not used
return 0;
}
#Override
public void writeToParcel(Parcel dest, int flags) {
dest.writeLong(id);
dest.writeString(title);
dest.writeString(subtitle);
dest.writeString(summary);
dest.writeString(duration);
dest.writeString(author);
dest.writeString(date);
dest.writeString(mp3);
dest.writeLong(podcastCategoryId);
}
public static Creator<Podcast> CREATOR = new Creator<Podcast>() {
public Podcast createFromParcel(Parcel parcel) {
return new Podcast(parcel);
}
public Podcast[] newArray(int size) {
return new Podcast[size];
}
};

#Override
public Person[] newArray(int size) {
return null;
}
You should create there an array of that size and return it.
#Override
public Person[] newArray(int size) {
return new Person[size];
}

Solved it was actually very simple, forgot song url when i was writing to the parcel. Any when i missed that write that was why i was getting the weird exception for person object. it was expecting a person object but was getting something else. 1 day wasted oh well :(
#Override
public void writeToParcel(Parcel dest, int flags) {
dest.writeInt(id);
dest.writeInt(challenger_id);
dest.writeInt(friend_id);
dest.writeString(artist_name);
**dest.writeString(song_name);**
dest.writeString(image_url);
dest.writeString(song_url);
dest.writeString(answer_url);
dest.writeInt(challenge_attempts_left);
dest.writeInt(answer);
dest.writeParcelable(person, flags);
dest.writeParcelable(friend, flags);
}
