How to fix NullPointerException: Attempt to invoke virtual method 'java.lang.String com.example.rsolveapp.User.getEmail()'

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 {
TextView showEmail;
private static final String TAG = RsolverAccount.class.getSimpleName();
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.rsolveraccount);
setWidget();
showData();
}
private void showData () {
FirebaseUser firebaseUser = FirebaseAuth.getInstance().getCurrentUser();
if(firebaseUser != null) {
String email = firebaseUser.getEmail();
Log.d(TAG, email);
}
FirebaseAuth firebaseAuth = FirebaseAuth.getInstance();
DatabaseReference mDatabase;
mDatabase = FirebaseDatabase.getInstance().getReference().child("sraboetapp").child("userdesc").child(FirebaseAuth.getInstance().getCurrentUser().getUid());
ValueEventListener postListener = new ValueEventListener() {
#Override
public void onDataChange(com.google.firebase.database.DataSnapshot dataSnapshot) {
User user = dataSnapshot.getValue(User.class);
showEmail.setText(user.getEmail());
}
#Override
public void onCancelled(DatabaseError databaseError) {
}
};
mDatabase.addValueEventListener(postListener);
}
public void setWidget() {
showEmail = (TextView) findViewById(R.id.showEmail);
}
}
This is my User class
public class User implements Serializable{
private String email;
private String name, pass, id, phone;
private String key;
public User(){
}
public String getKey(){
return key;
}
public void setKey(String key){
this.key=key;
}
public String getEmail(){
return email;
}
public void setEmail(String email){
this.email=email;
}
public String getName(){
return name;
}
public void setName(String name){
this.name=name;
}
public String getPass(){
return pass;
}
public void setPass(String pass){
this.pass=pass;
}
public String getId(){
return id;
}
public void setId(String id){
this.id=id;
}
public String getPhone(){
return phone;
}
public void setPhone(String phone){
this.phone=phone;
}
#Override
public String toString(){
return " "+email+"/n"+
" "+name+"/n"+
" "+pass+"/n"+
" "+id+"/n"+
" "+phone;
}
public User(String Remail, String Rname, String Rpass, String Rid, String Rphone){
this.email=Remail;
this.name=Rname;
this.pass=Rpass;
this.id=Rid;
this.phone=Rphone;
}
}
This is my database structure
{
"description" : {
"-LpJNvsR3oIGA5pv1uOK" : {
"day" : "2",
"description" : "tes",
"eHour" : "12",
"eMin" : "12",
"sHour" : "12",
"sMin" : "12"
}
},
"userdesc" : {
"-LquV8N1AJbRdhSKMA2T" : {
"email" : "bryan5#gmail.com",
"id" : "870788464845",
"name" : "bry5",
"pass" : "123456",
"phone" : "484854484546"
}
}
}
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("");
}
});
}

Regarding opening login screen for first time using shared preferences in android

I have referred to many of the answers but still my app does not show the registration screen when the app opens for first time. I have made use of shared preferences. Any help would be appreciated.Thanks!
MainActivity.java:
public class MainActivity extends AppCompatActivity {

super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);

boolean firstStart=prefs.getBoolean("firstStart",true);
if (firstStart) {
//show start activity
showRegistration();
}
}
private void showRegistration() {
SharedPreferences prefs=getSharedPreferences("prefs",MODE_PRIVATE);

editor.putBoolean("firstStart",false);
editor.apply();

Update your onCreate with this
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
String name;
SharedPreferences prefs = this.getSharedPreferences( "prefs", MODE_PRIVATE);
boolean firstStart=prefs.contains("firstStart");
if (!firstStart) {
//show start activity
showRegistration();
}
}
And let me know it worked

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

this.user_name = user_name;
}

}
public void setUser_phone(String user_phone) {

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());
}
}

How to Use SharedPreferences in Retrofit2 onResponse method?

I am trying to get a user's login credentials while he signing in. I am sending to my database User_Email and User_Password then returning a Json like below. Actually the problem is simple but i dont know the solution, i am kinda new. I am %100 sure the error in my onResponse method. Because I am seeing this successfull response Toast, so i am getting successfull response but the problem here i dont know how to get this Json response into sharedpreferences. Thanks.
{
"User": [
{
"SSN": "123456789",
"FirstName": "Furkan",
"User_Role": "1"
}
]
}
And my model class for this response is :
public class UserList {
#SerializedName("User")
private User user;
public User getUser() {
return user;
}
public void setUser(User user) {
this.user = user;
}
}
public class User {
#SerializedName("SSN")
public String sSN;
#SerializedName("FirstName")
public String firstName;
#SerializedName("User_Role")
public intuserRole;
public String getsSN() {
return sSN;
}
public void setsSN(String sSN) {
this.sSN = sSN;
}
public String getFirstName() {
return firstName;
}
public void setFirstName(String firstName) {
this.firstName = firstName;
}
public int getUserRoleTypeId() {
return userRoleTypeId;
}
public void setUserRoleTypeId(int userRoleTypeId) {
this.userRoleTypeId = userRoleTypeId;
}
}
I am trying to add these userRoleTypeId, firstName and sSN to SharedPreferences in my call.enqueue onResponse. But i could not figure it out.
Here is my LoginActivity.class for the login:
public class LoginActivity extends AppCompatActivity implements View.OnClickListener {
Button bSignUp, bLogin;
EditText etPassword, etEmail;
private int userRoleTypeId;
private SharedPreferences sharedPreferences;
private ProgressDialog progressDialog;
Intent intent;
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_login);
bSignUp = (Button) findViewById(R.id.bSignUp);
bLogin = (Button) findViewById(R.id.bLogin);
bSignUp.setOnClickListener((View.OnClickListener) this);
bLogin.setOnClickListener((View.OnClickListener) this);
etPassword = (EditText) findViewById(R.id.etPassword);
etEmail = (EditText) findViewById(R.id.etEmail);
progressDialog = new ProgressDialog(this);
progressDialog.setTitle("Logging in");
progressDialog.setMessage("Please wait ....");
sharedPreferences = getApplicationContext().getSharedPreferences("LoginActivity",MODE_PRIVATE);
bLogin.setOnClickListener(this);
}
#Override
public void onClick(View view) {
switch (view.getId()) {
case R.id.bSignUp:
Intent SignUpIntent = new Intent(this, SignUpActivity.class);
startActivity(SignUpIntent);
break;
case R.id.bLogin:
String email = etEmail.getText().toString();
String password = etPassword.getText().toString();
if (!email.isEmpty() && !password.isEmpty()) {
progressDialog.show();
loginProcess(email, password);
this.userRoleTypeId = sharedPreferences.getInt(Constants.USERROLE, 0);
if (userRoleTypeId == 1) {
intent = new Intent(this, OrganizerHomeActivity.class);
startActivity(intent);
} else if(userRoleTypeId == 2 || userRoleTypeId == 3) {
intent = new Intent(this, UserHomeActivity.class);
startActivity(intent);
}
else{
Toast.makeText(LoginActivity.this, "Wrong email or password", Toast.LENGTH_SHORT).show();
}
} else {
Toast.makeText(LoginActivity.this, "Fields are empty", Toast.LENGTH_SHORT).show();
}
break;
default:
break;
}
}
private void loginProcess(String email, String password) {
LoginAPI loginAPI = RetrofitService.getClient().create(LoginAPI.class);
retrofit2.Call<UserList> call = loginAPI.loginUser(email,password);
call.enqueue(new Callback<UserList>(){
#Override
public void onResponse(Call<UserList> call, Response<UserList> response) {
//I am sure the fault in here. In below i tried to take Json response and fetch it into the Shared Preferences.
UserList userLists = response.body().getUser();
if(response.isSuccessful()){
SharedPreferences.Editor editor = sharedPreferences.edit();
editor.putBoolean(Constants.IS_LOGGED_IN, true);
// editor.putString(Constants.NAME, userLists.getFirstName);
//editor.putString(Constants.SSN, userLists.getsSN);
// editor.putInt(Constants.USERROLE, userLists.getuserRoleTypeId);
editor.apply();
// I am seeing this successfull response toast, so i am getting successfull response but the problem here i dont know how to get this Json response into sharedpref.
Toast.makeText(LoginActivity.this, "successfull response", Toast.LENGTH_SHORT).show();
}
progressDialog.dismiss();
}
#Override
public void onFailure(Call<UserList> call, Throwable t) {
Toast.makeText(LoginActivity.this, t.getMessage(), Toast.LENGTH_SHORT).show();
progressDialog.dismiss();
}
});
}
}

Try this
if(response.isSuccessful()){
List<User> userLists = response.body().getUser();
SharedPreferences settings = getSharedPreferences("Pref", MODE_PRIVATE);
SharedPreferences.Editor prefEditor = settings.edit();
editor.putBoolean(Constants.IS_LOGGED_IN, true);
prefeditor.putString("UserName", userLists.getUser().getFirstName());
prefEditor.putString(Constants.SSN, userLists.getUser().getsSN());
prefEditor.putInt(Constants.USERROLE, userLists.getUser().getUserRoleTypeId());
prefEditor.commit();
}
