I take data from the server:

Retrofit client = new Retrofit.Builder() .baseUrl(Constants.HOST) .addConverterFactory(GsonConverterFactory.create()) .build(); final UserApi service = client.create(UserApi.class); final Call<List<Room>> partRooms = service.getPartRooms(FROM_INT, TO_INT); new Thread(new Runnable() { @Override public void run() { try { Log.e("samuliak", "Start execute"); Response<List<Room>> response = partRooms.execute(); allRooms = response.body(); Log.e("samuliak", "exute is finished. List size > "+allRooms.size()); } catch (IOException e) { e.printStackTrace(); } } }).start();

Object Model:

 public class Room { @SerializedName("roomID") @Expose private Integer roomID; @SerializedName("name") @Expose private String name; @SerializedName("password") @Expose private String password; @SerializedName("creationDate") @Expose private Date creationDate; @SerializedName("owner") @Expose private User owner; public Room() {} public Room(Integer roomID, String name, String password, Date creationDate, User owner) { this.roomID = roomID; this.name = name; this.password = password; this.creationDate = creationDate; this.owner = owner; } public Integer getRoomID() { return roomID; } public void setRoomID(Integer roomID) { this.roomID = roomID; } public String getName() { return name; } public void setName(String name) { this.name = name; } public String getPassword() { return password; } public void setPassword(String password) { this.password = password; } public Date getCreationDate() { return creationDate; } public void setCreationDate(Date creationDate) { this.creationDate = creationDate; } public User getOwner() { return owner; } public void setOwner(User owner) { this.owner = owner; }

}

Mistake:

How to solve?

The problem is solved, but a new one has appeared. Stack sheet error:

  • Show full class Room. by sight, you load the string into the byte array. - Yura Ivanov
  • added. I just translate the image into an array of bytes. - Samuliak
  • one
    In User? Well, do the same. Add an adapter that deserializes your image by string into bytes. - Yura Ivanov
  • Added User to the main post. In User, I accept the image and translate it into bytes. I can not understand how to fix .. - Samuliak
  • updated the answer ... - Yura Ivanov

Gson cannot recognize your date format, help it:

 GsonBuilder builder = new GsonBuilder(); builder.registerTypeAdapter(Date.class, new DateTypeAdapter()); builder.registerTypeAdapter(byte[].class, new ByteArrayAdapter()); Retrofit client = new Retrofit.Builder() .baseUrl(Constants.HOST) .addConverterFactory(GsonConverterFactory.create(builder.create())) .build(); public class DateTypeAdapter implements JsonDeserializer<Date>{ @Override public Date deserialize(JsonElement json, Type typeOfT, JsonDeserializationContext context) throws JsonParseException { return new Date(json.getAsLong()); } } public class ByteArrayAdapter implements JsonDeserializer<byte[]> { @Override public byte[] deserialize(JsonElement json, Type typeOfT, JsonDeserializationContext context) throws JsonParseException { return json.getAsString().getBytes(); } }

With an array not sure, better make your class-wrapper for byte [] ...

  • thanks, it helped. But there was a new mistake - Samuliak
