VerifyPhoneActivity.Java
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_verify_phone);
mAuth = FirebaseAuth.getInstance();
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 view) {
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);
}
private void signInWithCredential(PhoneAuthCredential credential) {
mAuth.signInWithCredential(credential)
.addOnCompleteListener(new OnCompleteListener<AuthResult>() {
#Override

if (task.isSuccessful()){
Intent intent = new Intent(VerifyPhoneActivity.this, List.class);
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TASK);
startActivity(intent);
}else{

ProfileActivity set as launcher activity and
add line of code at onCreate of ProfileAtivity
FirebaseUser user = FirebaseAuth.getInstance().getCurrentUser();
if(user==null){
Intent intent=new Intent(ProfileActivity,this,LoginActivity.class);
startActivity(intent);
finish()
}
else{
//stay here
}`
