onCreate( ) method gets called without any reason on pressing button

onCreate( ) method gets called without any reason on pressing button - android

In my app, First, I am verifying phone numbers by using phone authentication of firebase.
I am doing this process in the OTPVerificationActivity class. Every thing is working fine in this class, I am getting the OTP code also and the user gets signed in.
If the phone number is verified, then I am verifying the email by sending the verification email. I am doing this process in the EmailVerificationActivity class. In this class first, i am checking is the user exists or not. if the user is there, then I am logging out the user.
Then i create the account using createUserWithEmailAndPassword function. After this, i want to send a verification email to the user.
PROBLEM:- Now the problem is, after creating the account,onCreate method gets called again. Due to this, I am unable to send the verification email and the further task. So how to stop onCreate method from getting called again.
NOTE :-
I tried to run only EmailVerificationActivity not OTPVerificationActivity.
In that case every thing was working properly. I was able to send verification email and also able to verify the user.
But when i am using the OTPVerificationActivityand EmailVerificationActivity together i am getting this problem.
So please help me to solve this problem.

This is the android life cycle. onCreate() will be called again, if your activity was destroyed due to release memory, explicitly killing and etc.
When you switch activities usually activities won't get killed. but it may be killed in some cases. so please move your codes from onCreate() to somewhere else.
You can not control android life cycle. It will happen anyway. therefore you need to obey them

Firebase not sending SMS Android Studio

I'm creating an app for Android phones and using Firebase OTP authentication but I'm not sure if the codes are wrong or there's really an issue with Firebase sending SMS as what I've read as I have searched so far. Any help would be greatly appreciated!
This is the code:
public class MainActivity extends AppCompatActivity {
Button btSendCode;
Button btResend;
Button btVerify;
EditText etPhoneNumber;
EditText etEnterCode;
TextView tvGoHere;
String phoneVerificationID;
FirebaseAuth auth;
PhoneAuthProvider.OnVerificationStateChangedCallbacks verificationCallbacks;
PhoneAuthProvider.ForceResendingToken resendToken;

super.onCreate(savedInstanceState);

btSendCode = (Button) findViewById(R.id.button_sendcode);
btResend = (Button) findViewById(R.id.button_resend);
btVerify = (Button) findViewById(R.id.button_verify);
etPhoneNumber = (EditText) findViewById(R.id.edittext_phonenumber);
etEnterCode = (EditText) findViewById(R.id.edittext_entercode);
tvGoHere = (TextView) findViewById(R.id.textview_gohere);
auth = FirebaseAuth.getInstance();
}
public void clickSendCode(View view) {
etPhoneNumber.setVisibility(View.INVISIBLE);
btSendCode.setVisibility(View.INVISIBLE);
etEnterCode.setVisibility(View.VISIBLE);
btResend.setVisibility(View.VISIBLE);
btVerify.setVisibility(View.VISIBLE);
//firebase code
String phoneNumber = etPhoneNumber.getText().toString();
setUpVerificationCallbacks();
PhoneAuthProvider.getInstance().verifyPhoneNumber(
phoneNumber,
120,
TimeUnit.SECONDS,
this,
verificationCallbacks
);
}
public void setUpVerificationCallbacks() {
verificationCallbacks = new PhoneAuthProvider.OnVerificationStateChangedCallbacks() {
#Override
public void onVerificationCompleted(PhoneAuthCredential credential) {
signInWithPhoneAuthCredential(credential);
}
#Override
public void onVerificationFailed(FirebaseException e) {
if(e instanceof FirebaseAuthInvalidCredentialsException) {
Toast.makeText(MainActivity.this, "Invalid phone format", Toast.LENGTH_SHORT).show();
} else if(e instanceof FirebaseTooManyRequestsException) {
Toast.makeText(MainActivity.this, "Too many requests", Toast.LENGTH_SHORT).show();
}
}
#Override
public void onCodeSent(String verificationID, PhoneAuthProvider.ForceResendingToken token) {
phoneVerificationID = verificationID;
resendToken = token;
}
};
}
public void clickVerifyCode(View view) {
String code = etEnterCode.getText().toString();
PhoneAuthCredential credential = PhoneAuthProvider.getCredential(phoneVerificationID, code);
signInWithPhoneAuthCredential(credential);
}
public void signInWithPhoneAuthCredential(PhoneAuthCredential credential) {
auth.signInWithCredential(credential)
.addOnCompleteListener(new OnCompleteListener<AuthResult>() {
#Override

} else {
if(task.getException() instanceof FirebaseAuthInvalidCredentialsException) {

}
}
}
});
}
public void clickResendCode(View view) {
String phoneNumber = etPhoneNumber.getText().toString();
setUpVerificationCallbacks();
PhoneAuthProvider.getInstance().verifyPhoneNumber(
phoneNumber,
120,

this,
verificationCallbacks,
resendToken
);
}
public void onClickGoHere(View view) {
Intent intentLogin = new Intent(MainActivity.this, LoginActivity.class);
startActivity(intentLogin);
}
}

Phone number must begin with +, followed by country code and followed by number. Example: +9195021*****. And enable phone authentication sign method .

Login Failed When Saving Data.(Sign-up)

I'm making an Android project, and for starters I have been figuring out how signing up works. By the way, I used Firebase for this. Here's my code:
package com....
import...
public class MainActivity extends AppCompatActivity {
//VIEW AND WIDGETS
Button createUser, moveToLoginBtn;
EditText userEmailEdit, userPasswordEdit;
//FIREBASE AUTH FIELDS
FirebaseAuth nAuth;
FirebaseAuth.AuthStateListener nAuthlistener;

#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
//ASSIGN ID
createUser = (Button) findViewById(R.id.createUserBtn);
moveToLoginBtn = (Button) findViewById(R.id.moveToLogin);
userEmailEdit = (EditText) findViewById(R.id.emailEditTextCreate);
userPasswordEdit = (EditText) findViewById(R.id.passEditTextCreate);
//ASSIGN INSTANCE
mDatabaseRef = FirebaseDatabase.getInstance().getReference();
mUserCheckData = FirebaseDatabase.getInstance().getReference().child("Users");
nAuth = FirebaseAuth.getInstance();
nAuthlistener = new FirebaseAuth.AuthStateListener(){
#Override
public void onAuthStateChanged(#NonNull FirebaseAuth firebaseAuth) {
FirebaseUser user = firebaseAuth.getCurrentUser();
if (user != null) {
final String emailForVer = user.getEmail();
mUserCheckData.addValueEventListener(new ValueEventListener() {
#Override
public void onDataChange(DataSnapshot dataSnapshot) {
checkUserValidation(dataSnapshot, emailForVer);
}
#Override
public void onCancelled(DatabaseError databaseError) {
}
});
} else {
}
}
};
//ON CLICK LISTENER
createUser.setOnClickListener(new View.OnClickListener(){
#Override
public void onClick(View view) {
final String userEmailString, userPassString;
userEmailString = userEmailEdit.getText().toString().trim();
userPassString = userPasswordEdit.getText().toString().trim();
if (!TextUtils.isEmpty(userEmailString) && !TextUtils.isEmpty(userPassString))
{
nAuth.createUserWithEmailAndPassword(userEmailString,userPassString).addOnCompleteListener(new OnCompleteListener<AuthResult>() {
#Override
public void onComplete(#NonNull Task<AuthResult> task) {
if (task.isSuccessful())
{
DatabaseReference mChildDatabase = mDatabaseRef.child("Users").push();
String key_user = mChildDatabase.getKey();
mChildDatabase.child("isVerified").setValue("unverified");
mChildDatabase.child("userKey").setValue(key_user);
mChildDatabase.child("emailUser").setValue(userEmailString);
mChildDatabase.child("passWordUser").setValue(userPassString);
Toast.makeText(MainActivity.this, "User Account Created!", Toast.LENGTH_LONG).show();
startActivity(new Intent(MainActivity.this, Profile.class));
}
else
{
Toast.makeText(MainActivity.this, "User Account Creation Fail", Toast.LENGTH_LONG).show();
startActivity(new Intent(MainActivity.this, MainActivity.class));
}
}
});
}
}
});
//MOVE TO LOGIN
moveToLoginBtn.setOnClickListener(new View.OnClickListener(){
#Override
public void onClick(View view){
startActivity(new Intent(MainActivity.this, LoginActivity.class));
}
});
}
private void checkUserValidation(DataSnapshot dataSnapshot, String emailForVer) {
Iterator iterator = dataSnapshot.getChildren().iterator();
while (iterator.hasNext())
{
DataSnapshot dataUser = (DataSnapshot) iterator.next();
if(String.valueOf(dataUser.child("emailUser").getValue()).equals(emailForVer) && dataUser.child("emailUser") != null)
{
if(String.valueOf(dataUser.child("isVerified").getValue()).equals("unverified") && dataUser.child("isVerified") != null)
{
Intent in = new Intent(MainActivity.this, Profile.class);
in.putExtra("USER_KEY" , String.valueOf(dataUser.child("userKey").getValue()));
startActivity(in);
//in.putExtra("NAME_KEY" , String.valueOf(dataUser.child("nameKey").getValue()));
}else
{
startActivity(new Intent(MainActivity.this, Welcome.class));
}
}
}
}
#Override

super.onStart();
nAuth.addAuthStateListener(nAuthlistener);
}
#Override
protected void onStop() {
super.onStop();
nAuth.removeAuthStateListener(nAuthlistener);
}
}
I think I have implemented my methods correctly. But it toasts:
User Account Creation Failed
Is my
checkUseValidation() method wrong? Any kind of help is appreciated.
Also please pay attention to my:
public void onComplete
method, I have set it right I think. I don't know why the data isn't getting saved to the firebase database. Or why is the task unsuccesful as show in line:
if (task.isSuccessful())
Thank you very much.

First, you should change the toast, in your fail condition, to
Toast.makeText(MainActivity.this, task.getException().getMessage(), Toast.LENGTH_LONG).show();
So that you get what wrong in the task.
But before that did you enable Email/Password in the console????

See Sign up new users from url: https://firebase.google.com/docs/auth/android/start/?authuser=0
If task.isSuccessful() is false.You can add this to get error
Log.w(TAG, "createUserWithEmail:failure",task.getException());
Update you code as:
createUser.setOnClickListener(new View.OnClickListener(){
#Override
public void onClick(View view) {
final String userEmailString, userPassString;
userEmailString = userEmailEdit.getText().toString().trim();
userPassString = userPasswordEdit.getText().toString().trim();
if (!TextUtils.isEmpty(userEmailString) && !TextUtils.isEmpty(userPassString))
{
nAuth.createUserWithEmailAndPassword(userEmailString,userPassString).addOnCompleteListener(new OnCompleteListener<AuthResult>() {
#Override
public void onComplete(#NonNull Task<AuthResult> task) {
if (task.isSuccessful())
{
DatabaseReference mChildDatabase = mDatabaseRef.child("Users").push();
String key_user = mChildDatabase.getKey();
mChildDatabase.child("isVerified").setValue("unverified");
mChildDatabase.child("userKey").setValue(key_user);
mChildDatabase.child("emailUser").setValue(userEmailString);
mChildDatabase.child("passWordUser").setValue(userPassString);
Toast.makeText(MainActivity.this, "User Account Created!", Toast.LENGTH_LONG).show();
startActivity(new Intent(MainActivity.this, Profile.class));
}
else
{
Log.w("TAG", "createUserWithEmail:failure",task.getException());
Toast.makeText(MainActivity.this, "User Account Creation Fail", Toast.LENGTH_LONG).show();
startActivity(new Intent(MainActivity.this, MainActivity.class));
}
}
});
}
}
});
You should see warning in logcat:

Firebase / Facebook - How to Log Off / Sign Off?

I am stuck in a loop here.
Users can log in with their FB account. The app creates a Firebase user w/ the same info.
With the launcher activity (LoginActivity), if it detects an user is already logged in, it redirects them to their profile fragment.
However, on the profile fragment, I click the log off button and redirect
them to the Login page. This is where the cycle begins.
From code snippets and official Firebase doc, I am using .unauth();. However, my logcat still shows the user is logged in. I've also tried using the Facebook SDK method of LoginManager, but that hasn't worked either.
