What is this error ? How can I fix this? My app is running but can't load data. And this is my Error: Use JsonReader.setLenient(true) to accept malformed JSON at line 1 column 1 path $

This is my fragment :

public class news extends Fragment {
private RecyclerView recyclerView;
private ArrayList<Deatails> data;
private DataAdapter adapter;
private View myFragmentView;
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
    myFragmentView = inflater.inflate(R.layout.news, container, false);
    initViews();
    return myFragmentView;
private void initViews() {
    recyclerView = (RecyclerView) myFragmentView.findViewById(R.id.card_recycler_view);
    RecyclerView.LayoutManager layoutManager = new LinearLayoutManager(getActivity().getApplicationContext());
    recyclerView.setHasFixedSize(true);
    recyclerView.setLayoutManager(layoutManager);
    data = new ArrayList<Deatails>();
    adapter = new DataAdapter(getActivity(), data);
    recyclerView.setAdapter(adapter);
    new Thread()
        public void run()
            getActivity().runOnUiThread(new Runnable() {
                @Override
                public void run() {
                    loadJSON();
    .start();
private void loadJSON() {
    if (isNetworkConnected()){
        HttpLoggingInterceptor interceptor = new HttpLoggingInterceptor();
        interceptor.setLevel(HttpLoggingInterceptor.Level.BODY);
        OkHttpClient client = new OkHttpClient.Builder()
                .addInterceptor(interceptor)
                .retryOnConnectionFailure(true)
                .connectTimeout(15, TimeUnit.SECONDS)
                .build();
        Gson gson = new GsonBuilder()
                .setLenient()
                .create();
        Retrofit retrofit = new Retrofit.Builder()
                .baseUrl("http://www.memaraneha.ir/")
                .client(client)
                .addConverterFactory(GsonConverterFactory.create(gson))
                .build();
        RequestInterface request = retrofit.create(RequestInterface.class);
        Call<JSONResponse> call = request.getJSON();
        final ProgressDialog progressDialog = new ProgressDialog(getActivity());
        progressDialog.show();
        call.enqueue(new Callback<JSONResponse>() {
            @Override
            public void onResponse(Call<JSONResponse> call, Response<JSONResponse> response) {
                progressDialog.dismiss();
                JSONResponse jsonResponse = response.body();
                data.addAll(Arrays.asList(jsonResponse.getAndroid()));
                adapter.notifyDataSetChanged();
            @Override
            public void onFailure(Call<JSONResponse> call, Throwable t) {
                progressDialog.dismiss();
                Log.d("Error", t.getMessage());
    else {
        Toast.makeText(getActivity().getApplicationContext(), "Internet is disconnected", Toast.LENGTH_LONG).show();}
private boolean isNetworkConnected() {
    ConnectivityManager cm = (ConnectivityManager) getActivity().getSystemService(Context.CONNECTIVITY_SERVICE);
    NetworkInfo ni = cm.getActiveNetworkInfo();
    if (ni == null) {
        // There are no active networks.
        return false;
    } else
        return true;

RequestInterface :

public interface RequestInterface {
@GET("Erfan/news.php")
Call<JSONResponse> getJSON();

UPDATE (read below text and find your problem)

  • most of the time, this error isn't about your json but it could be a incorrect http request such as a missing or a incorrect header, first check your request with postman to verify the servers response and servers response headers. if nothing is wrong then the error mostly came from your programmed http request, also it could because the servers response is not json (in some cases response could be html).
  • I didn't ask for images. I asked you to print out the value that is maybe returned from the server. – OneCricketeer Oct 8, 2016 at 8:25 How do you print a value in Java? System.out.println, yes? In Android you can use the Log class, but that doesn't matter. You aren't getting data or an error is occurring at or around JSONResponse jsonResponse = response.body();. I don't know how to fix your error becuase it could be networking related. You should be able to inspect that value on your own. – OneCricketeer Oct 8, 2016 at 8:50 I'm not a pro either, I'm trying to teach you how to debug any Java application, nothing really Android specific – OneCricketeer Oct 8, 2016 at 16:00

    This is a well-known issue and based on this answer you could add setLenient:

    Gson gson = new GsonBuilder()
            .setLenient()
            .create();
    Retrofit retrofit = new Retrofit.Builder()
            .baseUrl(BASE_URL)
            .client(client)
            .addConverterFactory(GsonConverterFactory.create(gson))
            .build();
    

    Now, if you add this to your retrofit, it gives you another error:

    com.google.gson.JsonSyntaxException: java.lang.IllegalStateException: Expected BEGIN_OBJECT but was STRING at line 1 column 1 path $
    

    This is another well-known error you can find answer here (this error means that your server response is not well-formatted); So change server response to return something:

    android:[ { ver:"1.5", name:"Cupcace", api:"Api Level 3" }

    For better comprehension, compare your response with Github api.

    Suggestion: to find out what's going on with your request/response add HttpLoggingInterceptor in your retrofit.

    Based on this answer your ServiceHelper would be:

    private ServiceHelper() {
            httpClient = new OkHttpClient.Builder();
            HttpLoggingInterceptor interceptor = new HttpLoggingInterceptor();
            interceptor.setLevel(HttpLoggingInterceptor.Level.BODY);
            httpClient.interceptors().add(interceptor);
            Retrofit retrofit = createAdapter().build();
            service = retrofit.create(IService.class);
    

    Also don't forget to add:

    compile 'com.squareup.okhttp3:logging-interceptor:3.3.1'
                    i edit my question look . but give same error    : Use JsonReader.setLenient(true) to accept malformed JSON at line 1 column 1 path $ . also add error pic in question

                    @erfan see edited answer; The issue is because your response from server is Not correct; remove " around attribute name and issue will be fixed.

                    {     android:[         { ver:"1.5", name:"Cupcace", api:"Api Level 3" , pic:"pic2.jpg"}     ] }  this is my json exact like ur example and still same error :'(

                    {"android": [ {"ver":"1.5","name":"Cupcace","api":"level3","pic":"bane.jpg"}]} , fix with this way

    Using Moshi:

    When building your Retrofit Service add .asLenient() to your MoshiConverterFactory. You don't need a ScalarsConverter. It should look something like this:

    return Retrofit.Builder()
                    .client(okHttpClient)
                    .baseUrl(ENDPOINT)
                    .addConverterFactory(MoshiConverterFactory.create().asLenient())
                    .build()
                    .create(UserService::class.java)
    

    There was an error in understanding of return Type Just add Header and it will solve your problem

    @Headers("Content-Type: application/json")
    

    I have faced this problem and I made research and didn't get anything, so I was trying and finally, I knew the cause of this problem. the problem on the API, make sure you have a good variable name I used $start_date and it caused the problem, so I try $startdate and it works!

    as well make sure you send all parameter that declare on API, for example, $startdate = $_POST['startdate']; $enddate = $_POST['enddate'];

    you have to pass this two variable from the retrofit.

    as well if you use date on SQL statement, try to put it inside '' like '2017-07-24'

    I hope it helps you.

    In my case ; what solved my issue was.....

    You may had json like this, the keys without " double quotations....

    { name: "test", phone: "2324234" }

    So try any online Json Validator to make sure you have right syntax...

    Json Validator Online

    I solved this problem very easily after finding out this happens when you aren't outputting a proper JSON object, I simply used the echo json_encode($arrayName); instead of print_r($arrayName); With my php api.

    Every programming language or at least most programming languages should have their own version of the json_encode() and json_decode() functions.

    Sometimes the error is displayed because the Relative link cannot find the data in the Base URL; I experienced the same issue and counterchecking that there is no error between the relative URL and base URL worked

    I can't get the JSON data "Expected BEGIN_ARRAY but was BEGIN_OBJECT at line 1 column 2 path $" See more linked questions
