Usage of this Artist class

 Changes you need to do in your MainActivity and ShowTracksActivity classes:
 
 
 In MainActivity.class : 
 
  Artist artist = artists.get(position); 
  intent.putExtra ("key", artist);
   
 In ShowTracksActivity.class : 
 
  getIntent().getParcelableExtra("key"); 

How do you implement @SerializedName & @expose ? Cannot resolve symbol 'SerializedName'

Anyway, I want to thank you for your help !

@serailzdename & @expose are part of the Gson library, if you want you can remove them it will not be problem(edited the gist for your convenience), Gson is used for parsing JSON to POJO by the way.

Please accept my answer if it helped you. Thanks

Before getting your code, I did this (it seems similar):

`public class Artist implements Parcelable {

private String mAlbumTitle, mAlbumImage, mArtistName;
private String [] mTracks;

public int describeContents() {
    return 0;
}

public void writeToParcel(Parcel out, int flags) {
    out.writeString(mAlbumTitle);
    out.writeString(mAlbumImage);
    out.writeString(mArtistName);
    out.writeStringArray(mTracks);
}

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

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

private Artist(Parcel in) {
    mAlbumTitle = in.readString();
    mAlbumImage = in.readString();
    mArtistName = in.readString();
    mTracks = in.createStringArray();
}

public Artist(String artistName, String albumTitle, String albumImage, String [] tracks){
    mAlbumTitle = albumTitle;
    mAlbumImage = albumImage;
    mArtistName = artistName;
    mTracks = tracks;
}

public String getAlbumTitle(){
    return mAlbumTitle;
}

public String getAlbumImage(){
    return mAlbumImage;
}

public String getArtistName(){
    return mArtistName;
}

public String[] getTracks(){
    return mTracks;
}

}`

With your proposition of getIntent().getParcelableExtra("key"); it returns to me this : com.example.android.app.Artist@e54b310
But I don't kown how get data.

getIntent().getParcelableExtra("key").get(index) does not work...

YES !

I did this and it works !

Intent intent = getIntent();
Artist value = (Artist) intent.getParcelableExtra("key");

Thank you so much for your help !

You're welcome. And you figured out the problem great work for that.
