stuck in getting arraylist from another class in android

I’m making a project in which i get data through api and stored it in arraylist but when i return it, it is empty.
Can Anyone Help Me Out?
Here is the Main Activity
package com.example.trivia;
import androidx.appcompat.app.AppCompatActivity;
import androidx.cardview.widget.CardView;
import android.os.Bundle;
import android.util.Log;
import android.view.View;
import android.widget.Button;
import android.widget.ImageButton;
import android.widget.TextView;
import com.example.trivia.Data.Async;
import com.example.trivia.Data.setQ;
import com.example.trivia.controller.AppController;
import com.example.trivia.model.question;
import org.json.JSONArray;
import java.util.ArrayList;
import java.util.List;
public class MainActivity extends AppCompatActivity {
private CardView c;
private Button t_btn,f_btn;
private ImageButton next,prev;
private List<question>q;
private TextView set;
private int count=0;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
c=findViewById(R.id.cardView);
t_btn=findViewById(R.id.true_btn);
f_btn=findViewById(R.id.false_btn);
next=findViewById(R.id.next);
prev=findViewById(R.id.prev);
set=findViewById(R.id.setq);
//ArrayList<question> dummy = new ArrayList<question>();
//AppController.OnCreate();
q=new setQ().getData(new Async() {
#Override
public void finish(ArrayList<question> c) {
set.setText(c.get(count).getQ());
// Log.d("test", "onCreate: "+c);
}
});
Log.i("in main", "Main: "+q.size());
}
}
the code of setQ class
package com.example.trivia.Data;
import android.util.Log;
import com.android.volley.Request;
import com.android.volley.Response;
import com.android.volley.VolleyError;
import com.android.volley.toolbox.JsonArrayRequest;

import com.example.trivia.model.question;
import org.json.JSONArray;
import org.json.JSONException;
import java.lang.reflect.Array;
import java.util.ArrayList;
import java.util.List;
public class setQ {
ArrayList<question> q =new ArrayList<question>();
JSONArray r;
private String url="https://raw.githubusercontent.com/curiousily/simple-quiz/master/script/statements-data.json";
public List<question> getData(final Async call) {
final JsonArrayRequest jarr = new JsonArrayRequest(Request.Method.GET, url, (JSONArray)null, new Response.Listener<JSONArray>() {
#Override
public void onResponse(JSONArray response) {
r=response;
for (int i = 0; i < response.length(); i++) {
try {
JSONArray a = response.getJSONArray(i);
question k = new question(a.getString(0), a.getBoolean(1));
//Log.i("list", "onResponse: "+k.getAns());
q.add(k);
// Log.i("response", "onResponse: " +a.get(0));
} catch (JSONException e) {
e.printStackTrace();
}
}
if(call!=null) {
call.finish( q);
}
//return q;
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
}
});
Log.i("error ",""+AppController.getInstance());
AppController.getInstance().addToRequestQueue(jarr);
return q;
// return q;
}
}
output

Implement the callback pattern.
Create a new Interface file:
Interface MyVolleyResponse {
void onResponse(JSONArray response);
void onError(VolleyError error);
}
Your activity should implement this, as follows:
public class MainActivity extends AppCompatActivity implements MyVolleyResponse {...}
Add the new methods to your activity:
void onResponse(JSONArray response) {
// process your response here, building your question array...
}
void onError(VolleyError error) {
// handle errors here...
}
Change your Volley responses within SetQ:
public void onResponse(JSONArray response) {
callback.onResponse(response);
}
public void onErrorResponse(VolleyError error) {
callback.onError(error);
}
Create a constructor within SetQ to set the callback:
private MyVolleyResponse callback;
SetQ(MyVolleyResponse callback) {
this.callback = callback;
}
Call this constructor in your activity with:
SetQ volley = new SetQ(this);
Change the signnature of getData to just:
void getData() {...}
And run the Volley call with volley.getData().
Remove all AsyncTask objects in your code, because Volley is already asynchronous.

Activity layout lagging behind until before next transition to another activity

The problem is that, during transition from firstActivity to thisServiceActivity, the screen will freeze and then turn black. If service has performed it process and send the broadcast and receive by the broadcast receiver of thisServiceActivity, then it will finally show the layout of the thisServiceActivity and quickly transition to ResultActivity.
Is it because there is something I do wrong in its UI thread? I try to find similar discussion to this problem but can't find it.
firstActivity class will start a new activity which is thisServiceActivity class. thisServiceActivity have a layout that show a progressbar and textview. At the same time, it will start a service class name as myForegroundService with pending intent notification.
If the process in the service completed, the service will send a local broadcast that will be pickup by thisServiceActivity using broadcast receiver and it then stop the service and transition to resultActivity and finish its activity.
public class firstActivity extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);

You're blocking the UI thread for 10 seconds by waiting for the result of your AsyncTask:
process = new MyLoop().execute().get();
The Javadoc for get() states:
Waits if necessary for the computation to complete, and then retrieves its result.
This is eliminating any advantage to running it on a background thread and causing your app to freeze. If you need to do something with the result, you should do it in AsyncTask.onPostExecute.

GCM with sample android testapp for push notification

I have been trying to learn how to use the GCM by going over their step by step guild. I get to the point of registering but it never actually does the registration part of the project. I have the configuration file in the project and I am using this website to test for push notification http://www.androidbegin.com/tutorial/gcm.html
So this is what it is giving me in the logcat:

As it shows it get down to the start(intent0 part of the onCreate method. But it never reaches to the Register class at all. I am a bit stumped on what I am doing wrong here. Any help will be appreciated.

AsyncTask task onPostExecute() not executing? Tried all answer already present on stackoverflow

Hi Developers and friends,
I am working on an android application, which required to read JSON url. I am using AsyncTask. But I dont know why the onPostExecute() is not executing. I successfully parse the json. The only thing left is to return the string (having parse json text).
Here is my code:
package com.vijay.jsonwizard.demo.activities;
import android.content.Intent;
import android.os.AsyncTask;
import android.os.Bundle;
import android.support.v7.app.ActionBarActivity;
import android.util.Log;
import android.view.View;
import android.widget.Toast;
import com.squareup.okhttp.OkHttpClient;
import com.squareup.okhttp.Request;
import com.squareup.okhttp.Response;
import com.vijay.jsonwizard.demo.R;
import com.vijay.jsonwizard.activities.JsonFormActivity;
import org.apache.http.NameValuePair;
import org.apache.http.message.BasicNameValuePair;
import java.io.IOException;
import java.util.ArrayList;
import java.util.List;
public class MainActivity extends ActionBarActivity {
private static final int REQUEST_CODE_GET_JSON = 1;
private static final String TAG = "MainActivity";
private static final String DATA_JSON_PATH = "http://jatinderbhola.in/phppractice/data.json";
String json;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
findViewById(R.id.button_start).setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent intent = new Intent(MainActivity.this, JsonFormActivity.class);
BackgroundTask task = new BackgroundTask();
task.execute();
if (json != null) {
intent.putExtra("json", json);
startActivityForResult(intent, REQUEST_CODE_GET_JSON);
} else {
Toast.makeText(getApplicationContext(), "Error!!", Toast.LENGTH_LONG).show();
}
}
});
}
private class BackgroundTask extends AsyncTask < String, String, String > {
#Override
protected void onPreExecute() {
super.onPreExecute();
}
#Override
protected String doInBackground(String...params) {
OkHttpClient client = new OkHttpClient();
Request request = new Request.Builder()
.url(DATA_JSON_PATH)
.build();
Response response = null;
try {
response = client.newCall(request).execute();
} catch (IOException e) {
e.printStackTrace();
}
try {
//Log.d("Respose", response.body().string());
return response.body().string();
} catch (IOException e) {
e.printStackTrace();
}
return null;
}
#Override
protected void onPostExecute(String data) {
set_json(data);
}
}
private void set_json(String s) {
// json = s;
Toast.makeText(getApplicationContext(), "I'm in!!", Toast.LENGTH_LONG).show();
}
}
Thanks and advance.

Android Weather app crashing-network error

I have been developing a weather app through Treehouse and unfortunately no one has been able to help me fix this perticular error.
For some reason no weather data is retrieved on the app. I signed up through forecast IO to get the weather data to the app but nothing appears and the app crashes.
I use my phone as an emulator but I receive no errors in the log. Only when I use the Android Studio emulator do I receive an error in the logcat. Any suggestions ?

After reading through that and looking at your code, I believe the main culprit here is that you are doing to much on the main thread. You should use the android AsyncTask to run especially network connections on a separate thread. For example you might use:
private class DownloadForecast extends AsyncTask<String, Void, String> {
#Override
protected String doInBackground(String... urls) {
getForecast(); //run all your network intensive methods
return response;
