How to apply encoding to JSON in Android?

Question

Android

Hey!
I just can’t solve the problem with applying the encoding to the data received from JSON in the Android application.
So how to correctly apply the encoding to the Cyrillic alphabet?
Here is my code:

import android.app.Activity;
import android.app.ProgressDialog;
import android.content.ClipData;
import android.content.ClipboardManager;
import android.content.Context;
import android.content.Intent;
import android.content.SharedPreferences;
import android.os.AsyncTask;
import android.os.Bundle;
import android.support.annotation.NonNull;
import android.support.v4.app.Fragment;
import android.support.v7.preference.PreferenceManager;
import android.util.Log;
import android.view.LayoutInflater;
import android.view.MenuItem;
import android.view.View;

Thanks in advance for your help!
Z.Y. If anything, then here is the original code: here .

Answer 1

from the JSON from the server hardcoded into your code , you can see that "name": "Пример PSP°РїРёСЃР°РЅРёСЏ"
I would ask the backend developer to convert the text to a normal encoding, for example UTF-8
