How to save data to same table from different activities?

How to save data to same table from different activities? - java

Below is the code for both of my activities. By coding like this, the data get stored like this in firebase. This is a snapshot of the stored data:
This is what I get:
What I want is this
I know that this happens because I have two class for the database but I have tried to put in one class but it didn't work. I think it is because of my codes
Below are my codes:
Registration ACtivity`public class RegisterActivityUser extends AppCompatActivity {

This one edit profile activity: `private void updateUserInfo(final String weight, final String height, final FirebaseUser currentUser) {

currentUser.updateProfile(profileUpdate)
.addOnCompleteListener(new OnCompleteListener<Void>() {
#Override
public void onComplete(#NonNull Task<Void> task) {
if(task.isSuccessful()){
UserProfile user = new UserProfile (
weight,
height
);
FirebaseDatabase.getInstance().getReference("Users Profile")
.child(FirebaseAuth.getInstance().getCurrentUser().getUid())
.setValue(user).addOnCompleteListener(new OnCompleteListener<Void>() {
#Override
public void onComplete(#NonNull Task<Void> task) {
//progressBar.setVisibility(View.GONE);
if (task.isSuccessful()) {
//acc successfully registered
showMessage("Account Updated");}
else{
}
}
});
}
}
});

Replace this:
UserProfile user = new UserProfile (
weight,
height
);
FirebaseDatabase.getInstance().getReference("Users Profile")
.child(FirebaseAuth.getInstance().getCurrentUser().getUid())
.setValue(user)
With:
Map<String, Object> values = new HashMap<>();
values.put("height", height);
values.put("weight", weight);
FirebaseDatabase.getInstance().getReference("Users")
.child(FirebaseAuth.getInstance().getCurrentUser().getUid())
.updateChildren(values)
The relevant changes:
Call updateChildren instead of setValue, since setValue replace all data at the location you call it on.
Get a reference to /Users instead of /Users Profile.
Additional hint: consider storing the height and weight as numeric values, instead of strings. Otherwise ordering/filtering on them will become confusing, as Firebase uses lexicographical ordering for strings.

Link two tables in firebase using Id in android studio using Java

have a problem, I'm working on a university project, I have two tables in firebase, the gallery table that contains the photos of the itinerary and the itinerary table that contains the various itineraries of the users now I have to make sure that the id of the itinerary and the ID of the image so as to have a photo corresponding to each itinerary ì, also created by the same user. I did so:
public void addImageItinerary() {
storageReference = FirebaseStorage.getInstance().getReference();
referenceDb = FirebaseDatabase.getInstance().getReference();
firestore = FirebaseFirestore.getInstance();
auth = FirebaseAuth.getInstance();
if (images != null) {
StorageReference itineraryRef = storageReference.child("itinerary_image/" + FirebaseAuth.getInstance().getCurrentUser().getUid() + ".jpg");
itineraryRef.putFile(images).addOnCompleteListener(new OnCompleteListener<UploadTask.TaskSnapshot>() {
#Override
public void onComplete(#NonNull Task<UploadTask.TaskSnapshot> task) {
if (task.isSuccessful()) {
itineraryRef.getDownloadUrl().addOnSuccessListener(new OnSuccessListener<Uri>() {
#Override
public void onSuccess(Uri uri) {
String itineraryId = referenceDb.child("Itinerary").push().getKey();
Log.i("itineraryId", itineraryId);
HashMap<String, Object> map = new HashMap<>();
map.put("image", uri.toString());
referenceDb.child("Gallery").child(FirebaseAuth.getInstance().getCurrentUser().getUid()+ "/" + itineraryId).setValue(map).addOnCompleteListener(new OnCompleteListener<Void>() {
#Override
public void onComplete(#NonNull Task<Void> task) {
if (task.isSuccessful()) {
// APRO SCHERMATA MAPPA
// openMapFragment();
Toast.makeText(insertImage_fragment.getActivity(), "ok", Toast.LENGTH_SHORT).show();

//ERRORE
Toast.makeText(insertImage_fragment.getActivity(), "Operation failed. Please try again", Toast.LENGTH_SHORT).show();
}
}
});
}
});
} else {
Toast.makeText(insertImage_fragment.getActivity(), task.getException().toString(), Toast.LENGTH_SHORT).show();
}
}
});

Android firestore when users change the image, NullPointerException occurs

I'm making setup_profile activity. Users can change information.
When users do not change the image, it is good. But when the user change image errors come.
I add 'null checker' like
if (uri!=null) But I don know why it is.

How do i get an OTP the second time after I've logged out the first time?

After I log in the first time and log out, the next time I log in I don't get an OTP.
How do I solve this problem??
The code works fine if I enter the phone number for the first time. Second time onwards I am not getting OTP number. In order to get the OTP number, I need to restart my phone each time. If I close and reopen the app then it's not helping me too.

You should read docs if mobile gets registered on firebase it won't send OTP all time, maybe few times.
Once mobile is registered you will get success and then you can verify.

How to register user into firebase registration?

I am going to insert my email and password into Firebase Authentication. However, the code that I found on the Internet does not work for me? Below is the code and when I click next button, it goes back to the previous page too, it does not proceed with the next page?
public void completeRegis() {
username1 = username.getText().toString().trim();
email1 = email.getText().toString().trim();
psd1 = psd.getText().toString().trim();
psd2 = reconpsd.getText().toString().trim();
mAuth.createUserWithEmailAndPassword(email1, psd1)

#Override

//start profile activity here
User user = new User(username1, email1,psd1);

I am very new to android but I recently made a signUp page successfully.
declare a firebase auth instance
private FirebaseAuth mAuth;
private EditText mName, mEmailField, mConfirmPass, mNewPass;
then in onCreate() I declared them as
mName = (EditText) findViewById(R.id.eName);
mEmailField = (EditText) findViewById(R.id.fieldEmail);
mConfirmPass = (EditText) findViewById(R.id.fieldConfirm);
mNewPass = (EditText) findViewById(R.id.fieldNew);
mAuth = FirebaseAuth.getInstance();
I added a button in the authentication page for signup. Clicking on it starts the signUp procedure. This is done in onCreate() method
b1.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
startSignUp();
}
});
Then I declare the startSignUp() method as below
public void startSignUp(){
String name = mName.getText().toString();
String email = mEmailField.getText().toString();
String newPass = mNewPass.getText().toString();
String conPass = mConfirmPass.getText().toString();
if(TextUtils.isEmpty(name) || TextUtils.isEmpty(email) || TextUtils.isEmpty(newPass) || TextUtils.isEmpty(conPass)){
Toast.makeText(SignUp.this, "Fields Empty" , Toast.LENGTH_LONG).show();
}
mAuth.createUserWithEmailAndPassword(email,newPass).addOnCompleteListener(this, new OnCompleteListener<AuthResult>() {
#Override
public void onComplete(#NonNull Task<AuthResult> task) {
if(! task.isSuccessful()){
Toast.makeText(SignUp.this, "SignUp Failed", Toast.LENGTH_LONG).show();
}else {
openAuthetication();
}
}
});
}
}
If signUp is successful, it will go back to the authentication page for signing in. This is done in the openAuthetication() method.
public void openAuthetication(){
Intent intent = new Intent(this, Authetication.class);
startActivity(intent);
}

This unique id SiQEIDaQJfUBqZBBt1eo is generated when you are adding the user as a Map or when you are using a call to document() method without passing an argument.
In order to solve this, there are two ways. One would be to create a model class (UserModel), then create an object of that class and in the end get the uid of the user once it authenticated and add the object to the database like this:
String Name = textInputEditTextName.getText().toString().trim();
String Email = textInputEditTextEmail.getText().toString().trim();
String Password = textInputEditTextPassword.getText().toString().trim();
String Phone_Number = textInputEditTextPhone.getText().toString().trim();
String ConfirmPassword = textInputEditTextConfirmPassword.getText().toString().trim();
UserModel userModel = new UserModel(Name, Email, Password, Phone_Number, ConfirmPassword);
String uid = FirebaseAuth.getInstance().getCurrentUser().getUid();
FirebaseFirestore rootRef = FirebaseFirestore.getInstance();
CollectionReference usersRef = rootRef.collection("users");
usersRef.document(uid).set(userModel);
See, I have passed the uid as argument to the document() method.
The second approach would be to pass no argument to the document() method but to store that key into a variable like this:
String key = usersRef.document().getKey();
usersRef.document(key).set(userModel);
Edit:
There also another method, which I recommend you use it. Instead of using this line of code:
mFirebaseFirestore.collection("users")
.add(user)
.addOnSuccessListener(/* ... */)
Use the following line of code:
mFirebaseFirestore.collection("users")
.document(uid)
.set(user)
.addOnSuccessListener(/* ... */)
Remove the old data, add fresh one and your problem will be solved.
