URL_LOGIN,
new Response.Listener<String>() {
#Override
public void onResponse(String response) {
try {
JSONObject jsonObject = new JSONObject(response);
/////////////////////THIS TOAST I AM TALKING ABOUT
Toast.makeText(getApplicationContext(), jsonObject+"", Toast.LENGTH_LONG).show();
if (!jsonObject.getBoolean("error")) {
startActivity(new Intent(LoginActivity.this, MainActivity.class);
}
if(jsonObject.getBoolean("error")){
if(jsonObject.getString("message").equals("ERROR")){
startActivity(new Intent(LoginActivity.this, Verify.class);
}
}
} catch (JSONException e) {
e.printStackTrace();
}
}
},
new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
}
}) {
#Override
protected Map<String, String> getParams() throws AuthFailureError {
Map<String, String> params = new HashMap<>();
params.put("email", username);
params.put("password", password);
return params;
}
};
stringRequest.setShouldCache(false);
RequestHandler.getInstance(this).addToRequestQueue(stringRequest);

am trying to save to save a fingerprint image which is a byte into mysql database from my android app.
public void save(View view) {
String id = efid.getText().toString().trim();
String left_finger_image = new String(Left_Finger_Image);
String right_finger_image = new String(Right_Finger_Image);
String left_finger_iso = new String(Left_Finger_ISOTemplate);
String right_finger_iso = new String(Right_Finger_ISOTemplate);
if(!id.equals("")){
StringRequest stringRequest = new StringRequest(Request.Method.POST, URL_SAVE_FINGERPRINT, new Response.Listener<String>() {
#Override
public void onResponse(String response) {
Log.d("res", response);
if (response.equals("error")==false) {
Toast.makeText(Enrollment.this, "Fingerprint Enrolled Successfully..", Toast.LENGTH_SHORT).show();
Intent intent = new Intent(Enrollment.this, MainActivity.class);
startActivity(intent);
finish();
} else if (response.equals("failure")==true) {
Toast.makeText(Enrollment.this, "Fingerprint Enrolled Failed..", Toast.LENGTH_SHORT).show();
}
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
Toast.makeText(Enrollment.this, error.toString().trim(), Toast.LENGTH_SHORT).show();
}
}){
#Override
protected Map<String, String> getParams() throws AuthFailureError {
Map<String, String> data = new HashMap<>();
data.put("fid", id);
data.put("l_finger",left_finger_image);
data.put("r_finger",right_finger_image);
data.put("l_finger_iso",left_finger_iso);
data.put("r_finger_iso",right_finger_iso);
return data;
}
};
RequestQueue requestQueue = Volley.newRequestQueue(getApplicationContext());
requestQueue.add(stringRequest);
}else{
Toast.makeText(this, "Fields can not be empty!", Toast.LENGTH_SHORT).show();
}
}
I want to change my StringRequest to a JsonArrayRequest in order to separate the return into different variables.
As I run this code below:
RequestQueue requestQueue = Volley.newRequestQueue(getApplicationContext());
StringRequest stringRequest = new StringRequest(Request.Method.POST, URL, new Response.Listener<String>() {
#Override
public void onResponse(String response) {
Log.d("res", response);
if (response.equals("failure")) {
Toast.makeText(MainActivity.this, "Ungültige Anmeldedaten", Toast.LENGTH_SHORT).show();
} else {
TV.setText(response);
//ID = Integer.parseInt(response);
//switchToMain();
}
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
Toast.makeText(MainActivity.this, error.toString().trim(), Toast.LENGTH_SHORT).show();
}
}){
#Override
protected Map<String, String> getParams() throws AuthFailureError {
Map<String, String> data = new HashMap<>();
data.put("email", email);
data.put("password", password);
return data;
}
};
requestQueue.add(stringRequest);
I return the response:
[{"id":"6","Username":"a","Email":"a","Password":"0cc175b9c0f1b6a831c399e269772661","Status":"Online"}]
, which is a JsonArray, isn´t it?
When I try to make a JsonArrayRequest I receive errors:
RequestQueue requestQueue = Volley.newRequestQueue(getApplicationContext());
JsonArrayRequest queue = new JsonArrayRequest(Request.Method.POST,URL,null,new Response.Listener<JSONArray>(){
#Override
public void onResponse(JSONArray response) {
if (response.equals("null")) {
Toast.makeText(MainActivity.this, "Ungültige Anmeldedaten", Toast.LENGTH_SHORT).show();
} else {
//ID = Integer.parseInt(response);
//switchToMain();
}
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
Toast.makeText(MainActivity.this, error.toString().trim(), Toast.LENGTH_SHORT).show();
}
}){
#Override
protected Map<String, String> getParams() throws AuthFailureError {
Map<String, String> data = new HashMap<>();
data.put("email", email);
data.put("password", password);
return data;
}
};
requestQueue.add(queue);
I receive the following error:
com.android.volley.ParseError: org.json.JSONException: End of input at character 0 of
Where is my mistake?
recently i've made a program that can upload image to mysql database via php, and now i'm gonna put that image to my circleImageView, but i've encountered some issue, if i do image update, the image won't refresh until i close the apps and run it again.
here is my code for displaying the image and others from mysql database
public void putAllUserData(final String username){
StringRequest stringRequest = new StringRequest(Request.Method.POST, databaseURL.viewUserData, new Response.Listener<String>() {
#Override
public void onResponse(String response) {
try {
JSONObject jsonObject = new JSONObject(response);
JSONArray jsonArray = jsonObject.getJSONArray("data");
for(int i = 0; i < jsonArray.length();i++){
JSONObject object = jsonArray.getJSONObject(i);
setUsername.setText(username);
setFullName.setText(object.getString("nama"));
setCountry.setText(object.getString("asal_negara"));
setGender.setText(object.getString("jenis_kelamin"));
prfImage = object.getString("image_path");
if(prfImage.isEmpty()){
Toast.makeText(profileActivity.this, "", Toast.LENGTH_SHORT).show();
}
else {
Picasso.get().load(prfImage).into(profileImage);
}
}
} catch (JSONException e) {
Toast.makeText(profileActivity.this, "Error " + e, Toast.LENGTH_SHORT).show();
e.printStackTrace();
}
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
Toast.makeText(profileActivity.this, "Error " + error, Toast.LENGTH_SHORT).show();
}
}){
#Nullable
#Override
protected Map<String, String> getParams() throws AuthFailureError {

return params;
}
};
Volley.newRequestQueue(this).add(stringRequest);

I've given permissions for Internet access to my application and the URL I'm using is right (I can do POST requests through postman correctly). But in my application the requests fail:
button.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
final String email = Email.getText().toString();
final String password = Password.getText().toString();
StringRequest stringRequest = new StringRequest(Request.Method.POST, server_url, new Response.Listener<String>() {
#Override
public void onResponse(String response) {
if (response.equalsIgnoreCase("exitoso")) {
Intent intent = new Intent(MainActivity.this, Home.class);
startActivity(intent);
finish();
} else {
Toast.makeText(MainActivity.this, "Todo mal", Toast.LENGTH_SHORT).show();
}
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
Toast.makeText(MainActivity.this, "Hubo un error", Toast.LENGTH_SHORT).show();
error.printStackTrace();
}
}) {
#Override
protected Map<String, String> getParams() {
Map<String, String> Params = new HashMap<String, String>();
Params.put("email", email);
Params.put("password", password);
return Params;
}
#Override
public Map<String, String> getHeaders() {
HashMap<String, String> headers = new HashMap<>();
headers.put("Content-Type", "application/x-www-form-urlencoded; charset=\"UTF-8");
return headers;
}
};
RequestQueue requestQueue = Volley.newRequestQueue(MainActivity.this);
requestQueue.add(stringRequest);
}
});
My emulator does not give me any responses, just stays on login activity (which is the main one).
Just rebuild the app, honestly it was that now it works.
I am using volley library to send data on server as a json. My server response successfully. Data is saving in database. But Volley execute the ErrorResponse, here is my code
private void upload(final Context context) {
String url = BASE_URL + "upload.php";
RequestQueue requestQueue = Volley.newRequestQueue(context);
StringRequest stringRequest = new StringRequest(Request.Method.POST, url, new Response.Listener<String>() {
#Override
public void onResponse(String response) {
Intent intent=new Intent(ProfilePictureActivity.this,HomeActivity.class);
startActivity(intent);
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
// Log.i("Error", "" + error);
Toast.makeText(context, "Cannot save", Toast.LENGTH_SHORT).show();
}
}) {
#Override
protected Map<String, String> getParams() throws AuthFailureError {
Map<String, String> stringMap = new HashMap<>();
stringMap.put("name", names);
stringMap.put("date_of_birth",dobs);
stringMap.put("address", presentAddress);
stringMap.put("phone",phone);
stringMap.put("email", email);
stringMap.put("image",phone+".jpg");
stringMap.put("photo",imageToString(bitmap));
return stringMap;
}
};
requestQueue.add(stringRequest);
}
