My App having the Phone authentication method for user register and login to firebase is working fine for some devices but in one device it had send the verification SMS only the first time i checked it. After that ,I even deleted that account from firebase console but it is not sending any verfication code on registering that number again.

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
public class MainActivity extends AppCompatActivity {
EditText editTextPhone, editTextCode;

Firebase not sending a auth code to mobile for verification please check what is the problem
because if your already regiter a number then 2nd time doesnot send if you want to try them to get otp then delete a number from firebase auth and try again
I am new to Android development. I am not getting OTP message from Fire base but if I enter the code manually then it works. I am not sure why I am not getting text message. Your help is highly appreciated. I am not sure whether I am doing correctly sendVerificationcode method correctly or not.
Steps Completed:
1) I added GSON file to app directory
2) I added test phone number in the firebase console
3) I added SHA1 code to fire base
4) I added SMS permission in the Android manifest file.
5) I enabled firebase authentication in Android studio
6) I tried different phone numbers too
VerifyPhoneActivity.java
public class VerifyPhoneActivity extends AppCompatActivity {
private String verificationId;

#Override

editText = findViewById(R.id.editTextCode);
String phonenumber = getIntent().getStringExtra("phonenumber");
sendVerificationCode(phonenumber);
findViewById(R.id.buttonSignIn).setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
String code = editText.getText().toString().trim();
if (code.isEmpty() || code.length() < 6) {
editText.setError("Enter code...");
editText.requestFocus();
return;
}
verifyCode(code);
}
});
}
private void verifyCode(String code) {
PhoneAuthCredential credential = PhoneAuthProvider.getCredential(verificationId, code);
signInWithCredential(credential);
}

}
#Override

Below code looks like not working:

// String code="000000";
if (code != null) {
editText.setText(code);

}

}
Use like this following:

{
#Override
public void onVerificationCompleted(PhoneAuthCredential credential)
{
// This callback will be invoked in two situations:

// 2 - Auto-retrieval. On some devices Google Play services can automatically
// detect the incoming verification SMS and perform verificaiton without
// user action.
Log.d(TAG, "onVerificationCompleted:" + credential);
Log.e("number","credential=-=-=>>><<>>>signInWithPhoneAuthCredential-->>");
signInWithPhoneAuthCredential(credential);
}
#Override
public void onVerificationFailed(FirebaseException e)
{
// This callback is invoked in an invalid request for verification is made,
// for instance if the the phone number format is not valid.
Log.e(TAG, "onVerificationFailed", e);
// Show a message and update the UI

}
#Override
public void onCodeSent(String verificationId,

// now need to ask the user to enter the code and then construct a credential
// by combining the code with a verification ID.
Log.e(TAG, "onCodeSent:" + verificationId+"<<token>>"+token);
// Save verification ID and resending token so we can use them later
mVerificationId = verificationId;
//mResendToken = token;
// ...
}
};
//String phoneNumber=Settings.PREFIX + Settings.PREFIX_PHONE;
String phoneNumber="your phone number with prefix";
Log.e("number","credential=-=-=>>>22222>>"+phoneNumber);
if(phoneNumber!=null && !phoneNumber.isEmpty())
{

}
Method:

Phone number must begin with +, followed by country code and followed by number. Example: +9195021*****. And enable phone authentication sign method .
I am doing a Phone Auth Login for android studio using Firebase, My java and XML code works for the First Activity but when I try to split it up so that it works using Second Activity it crashes.
The First Activity is for receiving the user's number and once the user has entered the number and presses "send" the user is taken to the Second Activity which validates the auth code and resends the code, I am able to get the code to be sent from the first page but when I go to the second page and enter it the app crashes. When I try to debug I get null values in both the edit text fields.

You initiate new mUser object.
mUser = new UserInformation();
Then trying to get getPhone_num() from it but there is no phone number in it.
mUser.getPhone_num();
You have to pass FirebaseUser user in intent while starting second activity and then get User object from getIntent()
