Error while posting variable from android client to php server

I want to make an activity to change user profil. The received part which is based on JSON, is properly working. I have tested by set variable manually in PHP code. However, when I have posted the variable from android to php, it cannot receive it. Anyone can tell me the problem ?
public class ProfilActivity extends AppCompatActivity {
private EditText editTextNama, editTextEmail, editTextPassword, editTextNohp;

Had the same problem could not figure what was wrong, but this worked for, dont forget to add the dependency in the gradle file
RequestQueue queue = Volley.newRequestQueue(getApplicationContext());
StringRequest postRequest = new StringRequest(com.android.volley.Request.Method.POST, YOUR_URL,
new Response.Listener<String>() {
#Override
public void onResponse(String response) {
try {
// do work here
} catch (JSONException e) {
e.printStackTrace();
Log.d("Response", "failed: " + response);
}
}
},
new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
Log.d("Error.Response", error.toString());
}
}
) {
#Override
protected Map<String, String> getParams() {
Map<String, String> params = new HashMap<String, String>();
//add your parameters here as key-value pairs
params.put("title", title);
return params;
}
};
queue.add(postRequest);
** implementation 'com.he5ed.lib:volley:android-cts-5.1_r4'

Try to modify your loadProifle() method like below
// define below variable to globally
String mRequestBody=null;
private void loadProfil() {
try {
JSONObject jsonBody = new JSONObject();
jsonBody.put("namekey", "paste here name");
jsonBody.put("emailkey", "paste here email");
jsonBody.put("passkey", "paste here password");
jsonBody.put("nokey", "paste here number");
mRequestBody = jsonBody.toString();
}catch(JSONException e){
e.printStackTrace();
}
StringRequest stringRequest = new StringRequest(Request.Method.POST, PROFIL_URL, new Response.Listener<String>() {
#Override
public void onResponse(String response) {
try {
JSONArray profil = new JSONArray(response);
JSONObject profilObject = profil.getJSONObject(0);
String foto_user = profilObject.getString("foto_user");
String username = profilObject.getString("username");
String email = profilObject.getString("email");
String password = profilObject.getString("password");
String nohp = profilObject.getString("nohp");
Profil viewProfil = new Profil(foto_user, username, email, password, nohp);
profilList.add(viewProfil);
editTextNama.setText(username);
editTextEmail.setText(email);
editTextPassword.setText(password);
editTextNohp.setText(nohp);
} catch (JSONException e) {
e.printStackTrace();
}
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
Toast.makeText(ProfilActivity.this, error.getMessage() + "Error Load Profil", Toast.LENGTH_LONG).show();
}
}){
#Override
public byte[] getBody() throws AuthFailureError {
try {
return mRequestBody == null ? null : mRequestBody.getBytes("utf-8");
} catch (UnsupportedEncodingException e) {
e.printStackTrace();
return null;
}
}
};
Volley.newRequestQueue(this).add(stringRequest);
}

Here is my php code for getting email variable.
Is there something wrong?
<?php
define('DB_HOST','Localhost');
define('DB_USER','id9815170_phpjember');
define('DB_PASS','phpjember');
define('DB_NAME','id9815170_phpjember');
$conn = new mysqli(DB_HOST, DB_USER, DB_PASS, DB_NAME);
if(mysqli_connect_errno()){
die('Unable to connect to database ' . mysqli_connect_error());
}
$email = $_POST['email'];
$stmt = $conn->prepare("SELECT foto_user, username, email, password, nohp FROM datauser WHERE email='$email';");
$stmt->execute();
$stmt->bind_result($foto_user, $username, $email, $password, $nohp);
$profil = array();
while($stmt->fetch()){
$temp = array();
$temp['foto_user'] = $foto_user;
$temp['username'] = $username;
$temp['email'] = $email;
$temp['password'] = $password;
$temp['nohp'] = $nohp;
array_push($profil, $temp);
}
echo json_encode($profil);

How to create a single volley webservice class to use across the android app?

My android application uses multiple network calls in a single activity and i have several of these activities where i have to use both post and get requests. I want to create a single "VolleyWebservice" class and call the same in multiple activities instead of writing the complete volley code. I am relatively new to android development and i don't understand where i am going wrong.
public class VolleyWebService {
public JSONObject result;
public JSONObject getResponse(String url, Context mContext) {
RequestQueue mQueue = Volley.newRequestQueue(mContext);
JsonObjectRequest request = new JsonObjectRequest(Request.Method.GET, url, null, new Response.Listener<JSONObject>() {
#Override
public void onResponse(JSONObject response) {
Log.e(TAG, "Anshuman" + response.toString());
result = response;
}
},
new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
VolleyLog.d(TAG, "Error: " + error.getMessage());
}
});
mQueue.add(request);
return result;
}
}
The method in My activity where i am calling this class
private void callFunctionGetDist() {
ProgressDialog progressDialog;
progressDialog = ProgressDialog.show(recorddata.this, "", "Please Wait...", true);
JSONObject response = new VolleyWebService().getResponse(urlConfigClass.GET_DISTRICT, this);
try {
if(response.toString().contains("Status:Success,Details")){
arrDistName.clear();
arrDistCode.clear();
arrDistName.add("Select District Name");
arrDistCode.add("Select District Code");
JSONArray jsonArray = response.getJSONArray("Status:Success,Details");
for (int i = 0; i < jsonArray.length(); i++) {
JSONObject jobJ = jsonArray.getJSONObject(i);
String scheName = jobJ.getString("post");
JSONObject jobJDist = new JSONObject(scheName);
String distname = jobJDist.getString("District");
String distcode = jobJDist.getString("DistrictCode");
arrDistName.add(distname);
arrDistCode.add(distcode);
}
ArrayAdapter<String> dataAdapter = new ArrayAdapter<>(recorddata.this,
R.layout.custom_textview_to_spinner, arrDistName);
// Drop down layout style - list view with radio button
dataAdapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
// attaching data adapter to spinner
district.setAdapter(dataAdapter);
progressDialog.dismiss();
}else{
progressDialog.dismiss();
Toast.makeText(getApplicationContext(), "Response is null or empty", Toast.LENGTH_LONG).show();
}
} catch (Exception volleyError) {
progressDialog.dismiss();
Toast.makeText(getApplicationContext(), volleyError.getMessage(), Toast.LENGTH_LONG).show();
}
}
I tried creating the same class but i am not able to get the response to other activities. Although i am getting the correct response in the Volley jsonbject response, the response return null in other activities.
I want to have the result object return the response in my recorddata activity
This is what i have tried so far, no luck though!
public void postResponse (String url, Context mContext, final VolleyResponseListener listener) {
try {
String encodedUrl = url.replace(" ", "%20") + "";
if (encodedUrl.contains("("))
encodedUrl = encodedUrl.replace("(", "%28");
if (encodedUrl.contains(")"))
encodedUrl = encodedUrl.replace(")", "%29");
encodedUrl = encodedUrl.replace(" ", "%20");
RequestQueue mQueue = Volley.newRequestQueue(mContext);
JsonObjectRequest request = new JsonObjectRequest(Request.Method.POst, encodedUrl, null, new Response.Listener<JSONObject>() {
#Override
public void onResponse(JSONObject response) {
Log.e(TAG, "Anshuman" + response.toString());
listener.onSuccess(response);
}
},
new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
listener.onError(error);
}
}) {
#Override
protected Map<String, String> getParams() {
return new HashMap<>();
}
};
mQueue.add(request);
} catch (Exception e) {
e.printStackTrace();
}
}

For the sake of achieving your goal, (without taking in to consideration architecture and coding principles), you can pass a callback:
public class VolleyWebService {
public interface VolleyResponseListener {
void onSuccess(JSONObject response);
void onError(VolleyError error);
}
public JSONObject result;
public JSONObject getResponse(String url, Context mContext, VolleyResponseListener listener) {
RequestQueue mQueue = Volley.newRequestQueue(mContext);
JsonObjectRequest request = new JsonObjectRequest(Request.Method.GET, url, null, new Response.Listener<JSONObject>() {
#Override
public void onResponse(JSONObject response) {
Log.e(TAG, "Anshuman" + response.toString());
listener.onSuccess(response);
}
},
new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
listener.onError(error);
}
});
mQueue.add(request);
return result;
}
}
To use it:
volleyWebService.getResponse("your url", context, new VolleyResponseListener() {
#Override
void onSuccess(JSONObject response) {
//do what you want on success
}
#Override
void onError(VolleyError error) {
//do what you want on error
}
});

How to add Images with Picasso

Volley PUT image request

I am trying to make a volley PUT request to upload an image, Since httpEntity is deprecated now, I had to do some other research, I came across these solutions and tried to implement them into my code :
1. https://gist.github.com/anggadarkprince/a7c536da091f4b26bb4abf2f92926594
2. How to send multipart request using Volley without HttpEntity?
3. Working POST Multipart Request with Volley and without HttpEntity
but still I cannot upload my image. The image I want to upload is either captured from the camera or selected in the gallery, and it is executed onClick.

I am not sure what is causing my problem,please help, thank you!

Here is Simple Solution And Complete Example for Uploading File Using Volley Android
1) Gradle Import
compile 'dev.dworks.libs:volleyplus:+'
2)Now Create a Class RequestManager
public class RequestManager {
private static RequestManager mRequestManager;
/**
* Queue which Manages the Network Requests :-)
*/
private static RequestQueue mRequestQueue;
// ImageLoader Instance
private RequestManager() {
}
public static RequestManager get(Context context) {
if (mRequestManager == null)
mRequestManager = new RequestManager();
return mRequestManager;
}
/**
* #param context application context
*/
public static RequestQueue getnstance(Context context) {
if (mRequestQueue == null) {
mRequestQueue = Volley.newRequestQueue(context);
}
return mRequestQueue;
}
}
3)Now Create a Class to handle Request for uploading File WebService
public class WebService {
private RequestQueue mRequestQueue;
private static WebService apiRequests = null;
public static WebService getInstance() {
if (apiRequests == null) {
apiRequests = new WebService();
return apiRequests;
}
return apiRequests;
}
public void updateProfile(Context context, String doc_name, String doc_type, String appliance_id, File file, Response.Listener<String> listener, Response.ErrorListener errorListener) {
SimpleMultiPartRequest request = new SimpleMultiPartRequest(Request.Method.POST, "YOUR URL HERE", listener, errorListener);
// request.setParams(data);
mRequestQueue = RequestManager.getnstance(context);
request.addMultipartParam("token", "text", "tdfysghfhsdfh");
request.addMultipartParam("parameter_1", "text", doc_name);
request.addMultipartParam("dparameter_2", "text", doc_type);
request.addMultipartParam("parameter_3", "text", appliance_id);
request.addFile("document_file", file.getPath());
request.setFixedStreamingMode(true);
mRequestQueue.add(request);
}
}
4) And Now Call The method Like This to Hit the service
public class Main2Activity extends AppCompatActivity implements Response.ErrorListener, Response.Listener<String>{
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main2);
Button button=(Button)findViewById(R.id.button);
button.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
uploadData();
}
});
}
private void uploadData() {
WebService.getInstance().updateProfile(getActivity(), "appl_doc", "appliance", "1", mChoosenFile, this, this);
}
#Override
public void onErrorResponse(VolleyError error) {
}
#Override
public void onResponse(String response) {
//Your response here
}
}
mChoosenFile is your image file

First of all convert your image bitmap to base64 string using the following code:
public String getStringImage(Bitmap bmp){
ByteArrayOutputStream baos = new ByteArrayOutputStream();
bmp.compress(Bitmap.CompressFormat.JPEG, 100, baos);
byte[] imageBytes = baos.toByteArray();
String encodedImage = Base64.encodeToString(imageBytes, Base64.DEFAULT);
return encodedImage;
}
Then make a PUT Request like the following one and pass the base64 string as a parameter of the request
url = "http://example.com";
StringRequest putRequest = new StringRequest(Request.Method.PUT, url,
new Response.Listener<String>()
{
#Override
public void onResponse(String response) {
// response
Log.d("Response", response);
}
},
new Response.ErrorListener()
{
#Override
public void onErrorResponse(VolleyError error) {
// error
Log.d("Error.Response", response);
}
}
) {
#Override
protected Map<String, String> getParams()
{
Map<String, String> params = new HashMap<String, String> ();
params.put("imageString", base64String);
return params;
}
};
queue.add(putRequest);
Refer Android Volley Tutorial if you face any difficulty in implementing volley request.

Want to move GET method inside POST, Volley

I want to move GET method inside (if) that located inside onResponse of POST request without calling URL again because once the user post edittext php file will echo json result that will show up inside listview in activity so if call URL again in other method nothing will show up, how can I do that please?
