Solved the crash with my profile page and got it to save artifical data, but found out my registration page is the problem and is not recording data. Here is my Userprofile.java for reference
public class UserProfile {
public String user_phone;
public String user_email;
public String user_name;
public UserProfile() {
}
public UserProfile(String user_phone, String user_email, String user_name) {
this.user_phone = user_phone;
this.user_email = user_email;
this.user_name = user_name;
}
public String getUser_phone() {
return user_phone;
}
public void setUser_phone(String user_phone) {
this.user_phone = user_phone;
}
public String getUser_email() {
return user_email;
}
public void setUser_email(String user_email) {
this.user_email = user_email;
}
public String getUser_name() {
return user_name;
}
public void setUser_name(String user_name) {
this.user_name = user_name;
}
}
Any help would be appreciated, i'd read extensively on the topic and can't seem to see whatever small issue is causing the hold-up. Any other pointers are also welcome.
Try changing:
#Override
public void onDataChange(DataSnapshot dataSnapshot) {
UserProfile userProfile = dataSnapshot.getValue(UserProfile.class);
assert userProfile != null;
mProfileName.setText(userProfile.getUser_name());
mProfileNumber.setText(userProfile.getUser_phone());
mProfileEmail.setText(userProfile.getUser_email());
}
With:
#Override
public void onDataChange(DataSnapshot dataSnapshot) {
UserProfile userProfile = dataSnapshot.getValue(UserProfile.class);
if(userProfile != null){
mProfileName.setText(userProfile.getUser_name());
mProfileNumber.setText(userProfile.getUser_phone());
mProfileEmail.setText(userProfile.getUser_email());
}
}

I am currently trying to add user details who have registered in my app using Firebase Phone authentication to Firebase Real time database. I am successfully able to verify a user, but I am not able to send to Details Activity class where I need the user to enter his details, instead I jump to MainActivity Directly.
I do get Toast "Phone Verified" whenever I add a new user.

It seems that in your Register class in checkUserProfile() function you are checking if userId from firebaseUser.getUid() is not null. At the moment this will always be not null, because you are already asserting that the user must be authenticated at this point.
Judging from your code this is just a mistake on your part. I assume that what you are trying to do is actually see if the details already exist in the FirebaseDatabase. You have a reference to the database which you are not using.
private void checkUserProfile() {
FirebaseUser firebaseUser = auth.getCurrentUser();
assert firebaseUser != null;
String userid = firebaseUser.getUid();
//Unused reference
reference = FirebaseDatabase.getInstance().getReference("Users").child(userid);
if (userid != null) {
Intent intent = new Intent(Register.this, MainActivity.class);
startActivity(intent);
}
But also my question would be, are you sure you want to use Realtime Database for user details? You are saving details in Details function using FirebaseFirestore. Didn't you want to check if the details already exist in FirebaseFirestore?
How to fix:
First, let's create the user data class:
public class User {
public String uid;
public String firstName;
public String lastName;
public String email;
public User {
// Default constructor required for calls to DataSnapshot.getValue(User.class)
}
public User(String uid, String firstName, String lastName, String email) {
this.uid = uid;
this.firstName = firstName;
this.lastName = lastName;
this.email = email;
}
}
Now, let's change the code in Details.java class to use User class:
private void register(String first_name, String last_name, String eMail) {
FirebaseUser firebaseUser = auth.getCurrentUser();
assert firebaseUser != null;
String userid = firebaseUser.getUid();
reference = FirebaseDatabase.getInstance().getReference("Users").child(userid);
User user = new User(userid, firstName, lastName, eMail)
reference.setValue(user).addOnCompleteListener(new OnCompleteListener<Void>() {
#Override
public void onComplete(#NonNull Task<Void> task) {
if(task.isSuccessful()){
Intent intent=new Intent(Details.this,MainActivity.class);
startActivity(intent);
}
else{
Toast.makeText(Details.this,"Registration failed...",Toast.LENGTH_SHORT).show();
}
}
});
}
Let's check if the registration details exist in the database in checkUserProfile() method:
private void checkUserProfile() {
FirebaseUser firebaseUser = auth.getCurrentUser();
assert firebaseUser != null;
String userid = firebaseUser.getUid();
reference = FirebaseDatabase.getInstance().getReference("Users").child(userid);
reference.addListenerForSingleValueEvent(new ValueEventListener() {
#Override
public void onDataChange(DataSnapshot dataSnapshot) {
if (dataSnapshot.exists()) {
Intent intent = new Intent(Register.this, MainActivity.class);
startActivity(intent);
}
else {
Toast.makeText(Register.this, "Profile doesnt exist", Toast.LENGTH_SHORT).show();
Intent intent = new Intent(Register.this, Details.class);
startActivity(intent);
}
}
#Override
public void onCancelled(DatabaseError error) {
// Failed to read value
Log.w(TAG, "Failed to read value.", error.toException());
}
});
}
Let me know if it works for you.
Firebase will generate a single unique key(UID) on registration of account whether using Email/Phone number. This key remains associated with that account until the account exists in the firebase authentication list.
So, once you register with some number/email at that time UID is created for the same. every time you fetch UID it will return that user UID, and you are also asserting Firebase User is NotNull So, every time you got UID from firebase and app move to the dashboard screen.
If you want to move users to a Detail screen then. You can also add a condition based on firebase User.
if(firebaseUser != null){
// Get UID and Move to Dashboard
}else{
// Move to Detail Screen
}
I was trying to show user's profile in an activity. But when I try to do this, it only shows email. Name, photo, phone number is not showing. How can I show all the field of current user?I
I tried
getCurrentuser()
to get current user info and set them in the field. But it is not showing all the field.

Android studio is showing that

getReference()
and

also may produce NullPOinterException.How can I solve every issues and correctly get the expected output? Here is a screenshot of profile.
You aren't actually defining the name of the user ,
Use this in onCompleteListener method of firebase auth
new UserProfileChangeRequest.Builder()
.setDisplayName(nameUser)
.build();
I'm trying to retrieve data from current logged in user from my firebase realtime database, but when i go into activity that suppose to show the data, the app crash with the following error "java.lang.NullPointerException: Attempt to invoke virtual method 'java.lang.String com.example.rsolveapp.User.getEmail()' on a null object reference"
This is the activity for showing the data
public class RsolverAccount extends AppCompatActivity {

super.onCreate(savedInstanceState);

Log.d(TAG, email);
}
FirebaseAuth firebaseAuth = FirebaseAuth.getInstance();

This is my User class

}
This is how i insert the data
private void RegisterUser() {
b1.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
String emailUser = e1.getText().toString().trim();
String passwordUser = e3.getText().toString().trim();
String name1 = e2.getText().toString();
String id = e5.getText().toString();
String phone = e6.getText().toString();
if (emailUser.isEmpty()){
e1.setError("Email tidak boleh kosong");
}
// jika email not valid
else if (!Patterns.EMAIL_ADDRESS.matcher(emailUser).matches()){
e1.setError("Email tidak valid");
}
// jika password kosong
else if (passwordUser.isEmpty()){
e3.setError("Password tidak boleh kosong");
}
//jika password kurang dari 6 karakter
else if (passwordUser.length() < 6){
e3.setError("Password minimal terdiri dari 6 karakter");
}
else {
//create user dengan firebase auth
auth.createUserWithEmailAndPassword(emailUser,passwordUser)
.addOnCompleteListener(Register.this, new OnCompleteListener<AuthResult>() {
#Override
public void onComplete(#NonNull Task<AuthResult> task) {
//jika gagal register do something
if (!task.isSuccessful()){
Toast.makeText(Register.this,
"Register gagal karena "+ task.getException().getMessage(),
Toast.LENGTH_LONG).show();
}
else {
//jika sukses akan menuju ke login activity
if(!isEmpty(e1.getText().toString()) && !isEmpty(e2.getText().toString()) && !isEmpty(e3.getText().toString()) && !isEmpty(e5.getText().toString())&& !isEmpty(e6.getText().toString())) {
submitUser(new User(e1.getText().toString(), e2.getText().toString(), e3.getText().toString(), e5.getText().toString(), e6.getText().toString()));
//Toast.makeText(this,"Wassup",Toast.LENGTH_SHORT).show();
/*startActivity(new Intent(MainActivity.this,MainActivity2.class));*/
//EditText etLocation = (EditText) findViewById(R.id.desc);
SharedPreferences sharedPref = getSharedPreferences("myuser", MODE_PRIVATE);
SharedPreferences.Editor editor = sharedPref.edit();
editor.putString("user", emailUser);
editor.apply();
Intent intent = new Intent(Register.this, MainActivity.class);
//intent.putExtra("location", etLocation.getText().toString());
startActivity(intent);
}
else{
InputMethodManager imm = (InputMethodManager)
getSystemService(Context.INPUT_METHOD_SERVICE);
imm.hideSoftInputFromWindow(
e1.getWindowToken(), 0);
}
}
}
});
}
}
});
}
private boolean isEmpty(String s) {
return TextUtils.isEmpty(s);
}
private void submitUser(User user) {
database.child("userdesc").push().setValue(user).addOnSuccessListener(this, new OnSuccessListener<Void>() {
#Override
public void onSuccess(Void aVoid) {
e1.setText("");
e2.setText("");
e3.setText("");
e4.setText("");
e5.setText("");
e6.setText("");
}
});
}
It seems like there is no valid User object in the data you're processing.
Your JSON is using push IDs for the child nodes under that, while your code is loading from FirebaseAuth.getInstance().getCurrentUser().getUid(). If you want to load the users by their UID, you should store them under their UID, with something like:
mDatabase = FirebaseDatabase.getInstance().getReference().child("sraboetapp").child("userdesc").child(FirebaseAuth.getInstance().getCurrentUser().getUid());
mDatabase.setValue(user);
Based on the code you added to your question submitUser should be:
private void submitUser(User user) {
database.child("userdesc").child(FirebaseAuth.getInstance().getCurrentUser().getUid()).setValue(user).addOnSuccessListener(this, new OnSuccessListener<Void>() {
#Override
public void onSuccess(Void aVoid) {
e1.setText("");
e2.setText("");
e3.setText("");
e4.setText("");
e5.setText("");
e6.setText("");
}
});
}
So my concern is that I am using Shared Preference to store Name in android and can also retrieve the same when logged in again.But, when some other person logs in from the same device, still the name stored is of the previous user. How can I change this and fetch the value of the New user name from firebase? P.S I am new to Android
Following is my code for Manual Login:-
public class ManualLogin extends AppCompatActivity implements View.OnClickListener{
private Button buttonRegister;
private EditText editTextEmail;
private EditText editTextPassword;
private TextView textViewSignup;
private EditText editTextName;
DatabaseReference databaseUsers;
private ProgressDialog progressDialog;
private FirebaseAuth firebaseAuth;
private static final String TAG = "FACELOG";
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_manual_login);
databaseUsers = FirebaseDatabase.getInstance().getReference("Users");
firebaseAuth = FirebaseAuth.getInstance();
if(firebaseAuth.getCurrentUser()!=null){
//profile activity here
finish();
startActivity(new android.content.Intent(getApplicationContext(), AccountActivity.class));
}
progressDialog = new ProgressDialog(this);
buttonRegister = (Button)findViewById(R.id.buttonRegister);
editTextEmail = (EditText)findViewById(R.id.editTextEmail);
editTextPassword = (EditText)findViewById(R.id.editTextPassword);
editTextName = (EditText)findViewById(R.id.editTextName);
textViewSignup = (TextView)findViewById(R.id.textViewSignup);
buttonRegister.setOnClickListener(this);
textViewSignup.setOnClickListener(this);
}
public void registerUser() {
String email = editTextEmail.getText().toString().trim();
String password = editTextPassword.getText().toString().trim();
final String name = editTextName.getText().toString().trim();
if(!TextUtils.isEmpty(name)) {
String id = databaseUsers.push().getKey();
Users users = new Users(id, name);
databaseUsers.child(id).setValue(users);
//Toast.makeText(this, "User Created", Toast.LENGTH_SHORT).show();
}else{
//email is empty
Toast.makeText(this, "Enter Name", Toast.LENGTH_SHORT).show();
//stop function execution
return;
}
if(TextUtils.isEmpty(email)){
//email is empty
Toast.makeText(this, "Enter Email id", Toast.LENGTH_SHORT).show();
//stop function execution
return;
}
if(TextUtils.isEmpty(password)){
//password is empty
Toast.makeText(this, "Enter Password", Toast.LENGTH_SHORT).show();
//stop function execution
return;
}
//if validations are fine
//show progressBar
progressDialog.setMessage("Registering User...");
progressDialog.show();
firebaseAuth.createUserWithEmailAndPassword(email, password).addOnCompleteListener(this, new OnCompleteListener<AuthResult>() {
#Override
public void onComplete(#NonNull Task<AuthResult> task) {
if(task.isSuccessful()){
//user is successfully registered & logged in
//profile activity here
finish();
startActivity(new android.content.Intent(getApplicationContext(), AccountActivity.class));
userProfile();
Toast.makeText(ManualLogin.this, "Registered Successfully", Toast.LENGTH_SHORT).show();
}
else{
Toast.makeText(ManualLogin.this, "Failed to Register", Toast.LENGTH_SHORT).show();
}
progressDialog.dismiss();
SharedPreferences sharedPref = getSharedPreferences("userName", Context.MODE_PRIVATE);
SharedPreferences.Editor editor = sharedPref.edit();
editor.putString("name", editTextName.getText().toString());
editor.commit();
//Toast.makeText(ManualLogin.this, "Name Saved", Toast.LENGTH_SHORT).show();
}
});
}
//set User Display name
private void userProfile(){
FirebaseUser user = firebaseAuth.getCurrentUser();
if(user != null){
UserProfileChangeRequest profileUpdate = new UserProfileChangeRequest.Builder()
.setDisplayName(editTextName.getText().toString().trim()).build();
user.updateProfile(profileUpdate).addOnCompleteListener(new OnCompleteListener<Void>() {
#Override
public void onComplete(#NonNull Task<Void> task) {
if(task.isSuccessful()){
Log.d("Testing", "User Profile Updated");
}
}
});
}
}
#Override
public void onClick(View v) {
if(v == buttonRegister){
registerUser();
}
if(v == textViewSignup){
//open login activity
finish();
startActivity(new android.content.Intent(this, LoginActivity.class));
}
}
}
Below is the code for AccountActivity:-
public class AccountActivity extends AppCompatActivity {
private Button logout;
private TextView textViewUserName;
private FirebaseAuth mAuth;
private FirebaseAuth firebaseAuth;
private String s;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_account);
logout = (Button)findViewById(R.id.logout);
textViewUserName = (TextView)findViewById(R.id.textViewUserName);
// Initialize Firebase Auth
mAuth = FirebaseAuth.getInstance();
firebaseAuth = FirebaseAuth.getInstance();
if(firebaseAuth.getCurrentUser() == null){
finish();
startActivity(new Intent(this, LoginActivity.class));
}
FirebaseUser sname = firebaseAuth.getCurrentUser();
textViewUserName.setText("Welcome "+ sname.getDisplayName());
SharedPreferences sharedPref = getSharedPreferences("userName", Context.MODE_PRIVATE);
String name = sharedPref.getString("name", "");
textViewUserName.setText("Welcome "+ name);
logout.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
mAuth.signOut();
LoginManager.getInstance().logOut();
updateUI();
#Override
public void onStart() {
super.onStart();
// Check if user is signed in (non-null) and update UI accordingly.
FirebaseUser currentUser = mAuth.getCurrentUser();
if (currentUser == null) {
updateUI();
}
}
private void updateUI() {
Toast.makeText(this, "You have Logged out", Toast.LENGTH_SHORT).show();
Intent accountIntent = new Intent(this, MainActivity.class);
startActivity(accountIntent);
finish();
}
}
when you login that time store data into sharedpreference like below
private void saveData(String value){
SharedPreferences sharedPreferences=getSharedPreferences("MyData",MODE_PRIVATE);
SharedPreferences.Editor editor=sharedPreferences.edit();
editor.putString("User",value);
editor.commit();
}
In read new user data into firebase database.
private void readData() {
// define only root node.
mFirebaseDatabase.child("User").addListenerForSingleValueEvent(new ValueEventListener() {
#Override
public void onDataChange(DataSnapshot dataSnapshot) {
//for(DataSnapshot singleSnapshot : dataSnapshot.getChildren()){
User user = dataSnapshot.getValue(User.class);
mEtPwd.setText(user.pwd);
mEtName.setText(user.name);
mEtEmail.setText(user.email);
saveData(user.name);
// }
}
#Override
public void onCancelled(DatabaseError databaseError) {
Log.e(TAG, "onCancelled", databaseError.toException());
}
});
}
I have an app that send sms templates with firebase user login.
I want to save sms logs for each user on firbase database so I will be able to see what messages each user sent. I have no idea how to make it probably ..
my code

}
after alot of researches i found that set and get class and i modify my code as below
public class Post {
private String message;
private String number;
private String user;
private String date;
public String getMessage() {
return message;
}
public void setMessage(String message) {
this.message = message;
}
public String getNumber() {
return number;
}
public void setNumber(String number) {
this.number = number;
}
public String getUser() {
return user;
}
public void setUser(String user) {
this.user = user;
}
public String getDate() {
return date;
}
public void setDate(String date) {
this.date = date;
}
}
then in activity that i need to Post data to firbase database i add that simple code
FirebaseDatabase database = FirebaseDatabase.getInstance();
DatabaseReference posts = database.getReference("Messages:");
//this code for keep posts even app offline until the app online again
posts.keepSynced(true);
Post post = new Post();
post.setMessage("Messsage");
post.setUser(name);
post.setNumber(num);
post.setDate(s);
posts.push().setValue(post);
