Data not coming to Firebase

When submitting to Firebase, only photos are sent, without text and database as such.
I do according to the guide, but I don’t understand what is the reason.
The guide probably uses the deprecated getDownloadUrl() method, but the photo does not suffer from this. I do not understand the reason for this, since I am still new in this area, please help, I no longer understand what to do. To understand something, look at Maineenter image description here

How to save all data inputed in fragments into database on click of completed using material stepper library

I am using this library - https://github.com/stepstone-tech/android-material-stepper to build a step by step registration system where users will fill each field one by one before finally saving users data into the database using a php script via JSON.
I have 2 problems.
1. After filling the data, I dont kow how to save the data that has been inputed into the database.
2 How to validate each data been inputed individually onClick of 'NEXT' button. (Although, number 1 is much more important for now, but if someome could help me out with both, GREAT!.)
I have done this with the use of just one activity and it works fine.
One of the fragment. 6 of them (They are all similar)
public class EmailRegisterFragment extends Fragment implements Step {
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View v = inflater.inflate(R.layout.fragment_email_register, container, false);
//initialize your UI
return v;
}
#Override
public VerificationError verifyStep() {
//return null if the user can go to the next step, create a new VerificationError instance otherwise
return null;
}
#Override
public void onSelected() {
//update UI when selected
}
#Override
public void onError(#NonNull VerificationError error) {
//handle error inside of the fragment, e.g. show error on EditText
}
}
One of the fragementLayout (They are all similar)
<?xml version="1.0" encoding="utf-8"?>

ActivityJava file
public class IntroActivity extends AppCompatActivity implements StepperLayout.StepperListener{
private StepperLayout mStepperLayout;
#Override
protected void onCreate(Bundle savedInstanceState) {
//remove action and status bar
if (getSupportActionBar() != null)
getSupportActionBar().hide();
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_intro);
mStepperLayout = (StepperLayout) findViewById(R.id.stepperLayout);
mStepperLayout.setAdapter(new MyStepperAdapter(getSupportFragmentManager(), this));
mStepperLayout.setListener(this);
}
#Override

Intent intent = new Intent(this, WelcomeActivity.class);
startActivity(intent);
}
public void goToRegisterWithPhone(View view){

Like I said I have done this with the use of just one Activity using the Volley library. Check it out.

How do use this same logic for the fragments??

this might be late but i think it would help to others. So for sure you can validate/Insert or whatever you want to do with your inputs on Next button click before going to next step, This is how you can do it in Kotlin
// To be somewhere inside your Step
override fun verifyStep(): VerificationError? {
if (validateStep()){
return null
}
else
VerificationError("Any error message")
}
Now here validateStep will be a function that returns True or false depending upon your needs. Here is a simple example of a validateStep() function. Here you can do anything like insertion or validation etc.
private fun validateStep(): Boolean {
var isValid = true
val name = binding.etCustomerName.text.toString()
val email = binding.etCustomerEmail.text.toString()
if (name.isEmpty()) {
isValid = false
}
if (email.isEmpty()) {
isValid = false
} else if (!Patterns.EMAIL_ADDRESS.matcher(email).matches()) {
isValid = false
}
return isValid
}
Do let me know if it helps anyone. Happy coding :)

I used android studio and xamp server.
The table contain: id, name, email,password, photo(path)

In the onActivityResult event, you already get the image URI. Use the setImageURI method.
Uri filePath = data.getData();
imageView.setImageURI(uri);

how to check if a table has been updated or inserted then wanted to do it, otherwise it in android

i use volley library on android code
i want to know check if my table has been updated or inserted then wanted to do it(A), otherwise it(B)
for example if my table updated or inserted then send (A)sms otherwise (B)toast
its my activity code:
public class DeviceAddActivity extends AppCompatActivity implements View.OnClickListener {
private static final String REGISTER_URL = "http://192.168.43.190/entezam/addphone.php";
public static final String KEY_CUSTNAME = "Customer_non";
public static final String KEY_PHONENAME = "Phone_Name";
public static final String KEY_IMEI = "IMEI";
private EditText editTextName;
private EditText editTextPhoneName;
private EditText editTextIMEI;
private Button buttonRegister;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_device_add);
editTextName = (EditText) findViewById(R.id.editTextcustname);
editTextPhoneName = (EditText) findViewById(R.id.editTextphonename);
editTextIMEI= (EditText) findViewById(R.id.editTextimei);
buttonRegister = (Button) findViewById(R.id.buttonRegister);
buttonRegister.setOnClickListener(this);
}
private void registerUser(){
final String Customer_non = editTextName.getText().toString().trim();
final String Phone_Name = editTextPhoneName.getText().toString().trim();
final String IMEI = editTextIMEI.getText().toString().trim();
StringRequest stringRequest = new StringRequest(Request.Method.POST, REGISTER_URL,
new Response.Listener<String>() {
#Override
public void onResponse(String response) {
Toast.makeText(DeviceAddActivity.this,response,Toast.LENGTH_LONG).show();
}
},
new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
Toast.makeText(DeviceAddActivity.this,error.toString(),Toast.LENGTH_LONG).show();
}
}){
#Override
protected Map<String,String> getParams(){
Map<String,String> params = new HashMap<String, String>();
params.put(KEY_CUSTNAME,Customer_non);
params.put(KEY_PHONENAME,Phone_Name);
params.put(KEY_IMEI,IMEI);
return params;
}
};
RequestQueue requestQueue = Volley.newRequestQueue(this);
requestQueue.add(stringRequest);
}
#Override
public void onClick(View v) {
if(v == buttonRegister){
registerUser();
}
}
and its my php code:
<?php
if($_SERVER['REQUEST_METHOD']=='POST'){
$Phone_Name = $_POST['Phone_Name'];
$Customer = $_POST['Customer_non'];
$IMEI = $_POST['IMEI'];
require_once('dbConnect.php');
$sql = "INSERT INTO phone_in (Phone_Name,Customer_non,IMEI) VALUES ('$Phone_Name','$Customer','$IMEI')";
if(mysqli_query($con,$sql)){
echo "Successfully Registered";
}else{
echo "Could not register";
}
}else{echo 'error';}

Adding a progress dialog to app whilst loading data from a volley

I'm trying to add a progress dialog to my app whilst it loads data from a volley. I've tried a few ways but i'm currently following this tutorial http://www.androidhive.info/2014/07/android-custom-listview-with-image-and-text-using-volley/ and was hoping it would look like the example used there. Please could someone take a look at my code so far! i'm not getting errors but it is not displaying like the example. As you can see i've created the method in onCreate and called the hide method in my response listeners.
Thank you!

Try Below Code
ProgressDialog pd = ProgressDialog.show(context,null,"Please wait");
JsonArrayRequest jsonRequest = new JsonArrayRequest(url, new Response.Listener<JSONArray>() {
#Override
public void onResponse(JSONArray response) {
if(pd!=null && pd.isShowing())
pd.dismiss();
// Code
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
if(pd!=null && pd.isShowing())
pd.dismiss();
// Code
});
app.requestQueue.add(jsonRequest);

Try this:
progress = ProgressDialog.show(this, "dialog title",
"dialog message", true);
By the way, you should have an introduction with AsyncTask and should display ProgressDialog in that task.

private ProgressBarCircularIndetermininate pBar;
pBar = (ProgressBarCircularIndetermininate) getView().findViewById(R.id.progressBarCircularIndetermininate);
private void makeJsonRequest() {
showProgressDialog();
StringRequest strReq = new StringRequest(Method.POST, URL.DASHBOARD, new Response.Listener<String>(){
#Override
public void onResponse(String response){
try {
} catch (JSONException e) {
e.printStackTrace();
}
}
hideProgressDialog();
}
},
new Response.ErrorListener()
{
#Override
public void onErrorResponse(VolleyError error) {
AppController.getInstance().volleyErrorHandler(error);
hideProgressDialog();
}
}) {
#Override
protected Map<String, String> getParams() {
Map<String, String> params = new HashMap<String, String>();
params.put("user_id", userID);
return params;
}
};
strReq.setRetryPolicy(new DefaultRetryPolicy(TIMEOUT, NUMOFATTEMPT, BACKOFMULT));
// Adding request to request queue
AppController.getInstance().addToRequestQueue(strReq, tag_string_req);
}
private void showProgressDialog() {
if (!pBar.isShown())
pBar.setVisibility(View.VISIBLE);
}
private void hideProgressDialog() {
if (pBar.isShown())
pBar.setVisibility(View.GONE);
}

I know I am late for this topic(5 years, 5 months late), but this might help future readers. It's quite easy to do this. Just create a Progress Dialog first before creating the StringRequest from volley.
ProgressDialog progressDialog = new ProgressDialog(context);
progressDialog.setTitle("Set Title");
progressDialog.setMessage("Set A Message");
progressDialog.setProgressStyle(ProgressDialog.STYLE_SPINNER);// There are 3 styles, You'll figure it out :)
progressDialog.setCancelable(false);
progressDialog.setIcon(R.drawable.open_food_facts_symbol);
Then after creating the String request, override the onRespose method and DISMISS the progress dialog there.(You'll be showing the Progress Dialog when you add the request to the request queue)
StringRequest stringRequest = new StringRequest(Request.Method.GET, url, new Response.Listener<String>()
{
#Override
public void onResponse(String response)
{
progressDialog.dismiss();
}
});
Or this will be the same when using Lamda expressions like this,
StringRequest stringRequest = new StringRequest(Request.Method.GET, url, response ->
{
progressDialog.dismiss();
});
Then after adding the ErrorListeners and the user agents, show the Progress Dialog after adding the StringRequest to the queue.
RequestQueue requestQueue = Volley.newRequestQueue(context);
requestQueue.add(stringRequest);
progressDialog.show();
That's it. All done. Here's the full code.
private void parseApiData(String productBarcode)
{
ProgressDialog progressDialog = new ProgressDialog(context);
progressDialog.setTitle("Connecting To the Database");
progressDialog.setMessage("We are not establishing a Connection to the Open Food Facts Database...");
progressDialog.setProgressStyle(ProgressDialog.STYLE_SPINNER);
progressDialog.setCancelable(false);
progressDialog.setIcon(R.drawable.open_food_facts_symbol);
//progressDialog.
String url = "this will be your url..";
StringRequest stringRequest = new StringRequest(Request.Method.GET, url, response ->
{
progressDialog.dismiss();
}
} catch (JSONException e) {
progressDialog.dismiss();
e.printStackTrace();
} catch (Exception e) {
progressDialog.dismiss();
statusCode = 0;
}
}, volleyError -> {
if (volleyError instanceof TimeoutError || volleyError instanceof NoConnectionError)
{
Toast.makeText(context, "Connection Error !", Toast.LENGTH_LONG).show();
}
else if (volleyError instanceof AuthFailureError)
{
Toast.makeText(context, "Authentication/ Auth Error !", Toast.LENGTH_LONG).show();
}
else if (volleyError instanceof ServerError)
{
Toast.makeText(context, "Server Error !", Toast.LENGTH_LONG).show();
}
else if (volleyError instanceof NetworkError)
{
Toast.makeText(context, "Network Error !", Toast.LENGTH_LONG).show();
}
else if (volleyError instanceof ParseError)
{
Toast.makeText(context, "Parse Error !", Toast.LENGTH_LONG).show();
}
activity.finish();
})
{
//Assigning the User Agent
#Override
public Map<String, String> getHeaders() {
Map<String, String> params = new HashMap<>();
params.put("User-Agent:", "Your custom user agent here");
return params;
}
};
RequestQueue requestQueue = Volley.newRequestQueue(context);
requestQueue.add(stringRequest);
progressDialog.show();
}
