Volley-AuthFailureError

Question

I am trying to insert new user in phpMyAdmin database when users populate textboxes on android device. For that i write php code and I test it on POSTMAN and it's works but when i test on android real device i got AuthFailureError! In POSTMAN i set Authorization to "No Auth". This is my code in android studio:

public class Registration extends AppCompatActivity {
private EditText name,surname,email,password,adress;
    private  Button btnLog;
    private RequestQueue requestQueue;
    private  static  final String URL="http://192.168.*.*/Log/LogUser.php";
    private StringRequest request;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_registruj_se);
        name=(EditText) findViewById(R.id.txtName);
        surname=(EditText)findViewById(R.id.txtSurname);
        email=(EditText)findViewById(R.id.txtEmail);
        password=(EditText)findViewById(R.id.txtPassword);
        adress=(EditText)findViewById(R.id.txtAdress);
       btnLog=(Button)findViewById(R.id.btnLog);
        requestQueue= Volley.newRequestQueue(this);
        btnLog.setOnClickListener(new View.OnClickListener(){

            @Override
            public void onClick(View v) {
                request=new StringRequest(Request.Method.POST,URL,new Response.Listener<String>(){
                    @Override
                    public void onResponse(String response) {
                        try
                        {
                            JSONObject jsonObject=new JSONObject(response);
                        if(jsonObject.names().get(0).equals("success")){
                            Toast.makeText(getApplicationContext(),"success:"+jsonObject.getString("success"),Toast.LENGTH_SHORT).show();

                            startActivity(new Intent(getApplicationContext(),Welcome.class));
                        }else{  Toast.makeText(getApplicationContext(),"error:"+jsonObject.getString("error"),Toast.LENGTH_SHORT).show();}

                        }

                        catch (JSONException e){e.printStackTrace();}
                    }
                },new Response.ErrorListener(){
                    @Override
                    public void onErrorResponse(VolleyError error) {


                        if (error instanceof NetworkError) {
                            Toast.makeText(getApplicationContext(),"Cannot connect to Internet...Please check your connection!",Toast.LENGTH_SHORT).show();
                        } else if (error instanceof ServerError) {
                            Toast.makeText(getApplicationContext(),"The server could not be found. Please try again after some time!!",Toast.LENGTH_SHORT).show();

                        } else if (error instanceof AuthFailureError) {
                            Toast.makeText(getApplicationContext(),"AuthFailureError",Toast.LENGTH_SHORT).show();
                        } else if (error instanceof ParseError) {
                            Toast.makeText(getApplicationContext(),"Parsing error! Please try again after some time!!",Toast.LENGTH_SHORT).show();

                        } else if (error instanceof NoConnectionError) {
                            Toast.makeText(getApplicationContext(),"NoConnectionError",Toast.LENGTH_SHORT).show();
                        } else if (error instanceof TimeoutError) {
                            Toast.makeText(getApplicationContext(),"Connection TimeOut! Please check your internet connection.",Toast.LENGTH_SHORT).show();

                        }
                    }
                })
                {

                   @Override
                    protected Map<String, String> getParams() throws AuthFailureError {
                        HashMap<String,String>hashMap=new HashMap<String, String>();
                        hashMap.put("name",name.getText().toString());
                        hashMap.put("surname",surname.getText().toString());
                        hashMap.put("email",email.getText().toString());
                        hashMap.put("password",password.getText().toString());
                        hashMap.put("adress",adress.getText().toString());
                        return  hashMap;
                    }

                    @Override
                    public Map<String, String> getHeaders() throws AuthFailureError {
                        HashMap<String, String> headers = new HashMap<String, String>();
                        // do not add anything here
                        return headers;
                    }
                    @Override
                    public String getBodyContentType() {
                        return "application/json";
                    }

                };
                requestQueue.add(request);
            }
        });

I appreciate any help!

Answer 1

Try this:

In getBodyContentType() method return "application/x-www-form-urlencoded" instead of "application/json"

Code

@Override
public String getBodyContentType() {
       return "application/x-www-form-urlencoded";
}
