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();
}
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'
Also this issue occurres when the response contenttype is not application/json
. In my case response contenttype was text/html
and i faced this problem. I changed it to application/json
then it worked.
