• E/Volley: [4084] BasicNetwork.performRequest: Unexpected response code 413 for http://www.......com/TrueCaller/submit_contacts.php 05-21 14:37:38.643 18773-18773/satsuma.callerid_realcaller W/System.err: com.android.volley.ClientError 05-21 14:37:38.644 18773-18773/satsuma.callerid_realcaller W/System.err: at com.android.volley.toolbox.BasicNetwork.performRequest(BasicNetwork.java:190) 05-21 14:37:38.644 18773-18773/satsuma.callerid_realcaller W/System.err: at com.android.volley.NetworkDispatcher.processRequest(NetworkDispatcher.java:120) 05-21 14:37:38.644 18773-18773/satsuma.callerid_realcaller W/System.err: at com.android.volley.NetworkDispatcher.run(NetworkDispatcher.java:87)*

        private void submitContacts(){

        // now here we convert this list array into json string

        Gson gson=new Gson();

        final String newDataArray=gson.toJson(dataArray); // dataarray is list aaray

        final String server_url="http://www.........com/TrueCaller/submit_contacts.php"; // url of server check this 100 times it must be working



        // volley

        StringRequest stringRequest=new StringRequest(Request.Method.POST, server_url,
                new Response.Listener<String>() {
                    @Override
                    public void onResponse(String response)
                    {

                        final String result=response.toString();
                        Log.d("response", "result : "+result); //when response come i will log it
                    }
                },
                new Response.ErrorListener() {
                    @Override
                    public void onErrorResponse(VolleyError error)
                    {
                        error.printStackTrace();
                        error.getMessage(); // when error come i will log it
                    }
                }
        )
        {
            @Override
            protected Map<String, String> getParams() throws AuthFailureError {
                Map<String,String> param=new HashMap<String, String>();
                param.put("array",newDataArray); // array is key which we will use on server side

                return param;
            }
        };
        Vconnection.getnInstance(this).addRequestQue(stringRequest); // vConnection i claas which used to connect volley

    }

array initialisation:

 if (phoneC != "") {
                Bitmap bitmap = retrieveContactPhoto(MainActivity.this, phoneC);
                String image = "";
                if (bitmap != null) {
                    image = getStringImage(bitmap);
                }

                Contact_Details dt = new Contact_Details(name, phoneC, UIDD, country_code, image, emailC, adressC);
                dataArray.add(dt);
            }

Contact_Details class is below:

public class Contact_Details {
String name;
String phone_no;
String identifier;
String country_code;

public String getCountry_code() {
    return country_code;
}

public void setCountry_code(String country_code) {
    this.country_code = country_code;
}

public String getImage() {
    return image;
}

public void setImage(String image) {
    this.image = image;
}

String image;

public String getEmail() {
    return email;
}

public void setEmail(String email) {
    this.email = email;
}

String email;

public String getAddress() {
    return address;
}

public void setAddress(String address) {
    this.address = address;
}

String address;

public Contact_Details(String name, String phone_no, String identifier, String country_code, String image, String email, String address) {
    this.name = name;
    this.phone_no = phone_no;
    this.identifier = identifier;
    this.country_code = country_code;
    this.image = image;
    this.email = email;
    this.address = address;
}


public String getName() {
    return name;
}

public void setName(String name) {
    this.name = name;
}

public String getPhone_no() {
    return phone_no;
}

public void setPhone_no(String phone_no) {
    this.phone_no = phone_no;
}

public String getIdentifier() {
    return identifier;
}

public void setIdentifier(String identifier) {
    this.identifier = identifier;
}
}

Answer 1

Is it absolutely necessary to send the array of Contact_Details to the server? is there a solution to just send one object of Contact_Details ?

413 error is Payload Too Large . More on that error here

Please also verify that Bitmap image to Base64 String conversion is working.

You can use the following class to do just that:

public class ImageUtil {
public static Bitmap convert(String base64Str) throws IllegalArgumentException {
    byte[] decodedBytes = Base64.decode(
            base64Str.substring(base64Str.indexOf(",") + 1),
            Base64.DEFAULT
    );

    return BitmapFactory.decodeByteArray(decodedBytes, 0, decodedBytes.length);
}

public static String convert(Bitmap bitmap) {
    ByteArrayOutputStream outputStream = new ByteArrayOutputStream();
    bitmap.compress(Bitmap.CompressFormat.JPEG, 100, outputStream);

    return Base64.encodeToString(outputStream.toByteArray(), Base64.DEFAULT);
}

}

Other than that you can check on the server side to see if the database supports strings of Base64 length.

Answer 2

below code is for array uploading to server:

private void submitContacts() {


    // now here we convert this list array into json string

    Gson gson = new Gson();

    final String newDataArray = gson.toJson(dataArray); // dataarray is list aaray

    final String server_url = "http://www.vvvv.com/Caller/submit_contacts.php"; // url of server check this 100 times it must be working


    // volley

    StringRequest stringRequest = new StringRequest(Request.Method.POST, server_url,
            new Response.Listener<String>() {
                @Override
                public void onResponse(String response) {

                    final String result = response.toString();
                    Log.d("response", "result : " + result); //when response come i will log it
                }
            },
            new Response.ErrorListener() {
                @Override
                public void onErrorResponse(VolleyError error) {
                    error.printStackTrace();
                    error.getMessage(); // when error come i will log it
                }
            }
    ) {
        @Override
        protected Map<String, String> getParams() throws AuthFailureError {
            Map<String, String> param = new HashMap<String, String>();
            param.put("array", newDataArray); // array is key which we will use on server side

            return param;
        }
    };
    Vconnection.getnInstance(this).addRequestQue(stringRequest); // vConnection i claas which used to connect volley


}

code of Vconnection class is below:

public class Vconnection {

private static Vconnection nInstance;
private RequestQueue RQ;
private Context CTX;

private Vconnection(Context context)
{
    CTX=context;
    RQ=getRequestQue();

}

public RequestQueue getRequestQue()
{
    if(RQ==null)
    {
        RQ= Volley.newRequestQueue(CTX.getApplicationContext());
    }
    return RQ;
}
public static synchronized Vconnection getnInstance(Context context)
{
    if(nInstance==null)
    {
        nInstance=new Vconnection(context);
    }
    return nInstance;
}
public <T> void addRequestQue(Request<T> request)
{
    int socketTimeout = 30000;
    RetryPolicy policy = new DefaultRetryPolicy(socketTimeout, DefaultRetryPolicy.DEFAULT_MAX_RETRIES, DefaultRetryPolicy.DEFAULT_BACKOFF_MULT);
    request.setRetryPolicy(policy);
    RQ.add(request);
}

}
