问题
I'm using phone number verification on signing in with google or fb. The verification was working good with no issue for past 30 days and I didnt change the code at all. But suudenly, the otp is not sending to some mobile numbers sometimes not sending at all. My logcat has no error to my knowledge. But im facing this issue for last week. I need some help on this issue.
public class MainActivity extends FragmentActivity {
private GoogleSignInClient mGoogleSignInClient;
private String mVerificationId;
private PinView pinView;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
//Intialize the Frebase Auth
mAuth = FirebaseAuth.getInstance();
db = FirebaseFirestore.getInstance();
// Configure Google Sign In
GoogleSignInOptions gso = new GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_SIGN_IN)
.requestIdToken(getString(R.string.default_web_client_id))
.requestEmail().build();
// Initialize the SigninApi client for Google Signin
mGoogleSignInClient = GoogleSignIn.getClient(this, gso);
Button signInButton = findViewById(R.id.googlesignin);
signInButton.setOnClickListener(v -> {
signIn();
});
}
//Google Signin Listener
private void signIn() {
Intent signInIntent = mGoogleSignInClient.getSignInIntent();
startActivityForResult(signInIntent, 9001);
}
@Override

// Google Sign In was successful, authenticate with Firebase

firebaseAuthWithGoogle(account);
}
Log.d("TAG", "Google sign in Success");
} catch (ApiException e) {
pbDialog.dismiss();
// Google Sign In failed, update UI appropriately
