그래서 사용자가 자신의 전화 번호를 사용하여 로그인 할 수 있도록 중포 기지에서 튜토리얼을 따라하기 위해 노력하고있어. 나는 튜토리얼 비디오를 시청했습니다. 내 모든 코드는 올바른 보인다. 난 내 테스트 장치에 그것을 시도 할 때하지만 난 널 포인터 오류가 발생합니다 ...

은 "+44"나는 잘못된 전화 번호를 입력 한 경우 보려고 덧붙였다. 내가 먼저 응용 프로그램의 편집 텍스트로 수동으로 44을 추가하여 그것을 시도하고 같은 오류를 준 ..
******편집하다******
그래서 또한 올바르게 전화 번호를 캡처 있는지 확인하기 위해 로그를 실행 .. 숫자보다 큰 9 자리였다 경우가 작동 않네으로 물었다 인증 제공자 내부의 선을 제거 필자.
Log.i("Verify_Phone_Number",getPhoneNumber);
2019-07-16 14:15:30.585 32055-32055/studios.p9p.chatomatic.chat_o_matic I/Verify_Phone_Number: +447******100 and it returns correctly
******편집하다******
좋아, 그래서 더 시험에 내가 제대로 작동 전화 번호를 입력하기 전에 btn_phone을 클릭하면,하지만 난 단순히 편집 테스트에 전화 번호를 추가하는 경우 먼저이 로그 캣 위의 메시지와 함께 충돌 thebtn_phone를 누르십시오

좋아, 그래서 난이 문제를 해결하는 방식은 코드에서 생성 섹션에 mcallbacks를 이동했다. 아래 그림과 같이
setContentView(R.layout.activity_phone__login);
mAuth = FirebaseAuth.getInstance();
InitVariables();
AddPhoneNumberButtons();
mcallbacks = new PhoneAuthProvider.OnVerificationStateChangedCallbacks() {
@Override
public void onVerificationCompleted(PhoneAuthCredential phoneAuthCredential) {
signInWithPhoneAuthCredential(phoneAuthCredential);
}
@Override
public void onVerificationFailed(FirebaseException e) {
Toast.makeText(getBaseContext(), "Wrong Or Invalid Phone Number...", Toast.LENGTH_SHORT).show();
AddPhoneNumberButtons();
if (e instanceof FirebaseAuthInvalidCredentialsException) {
Toast.makeText(getBaseContext(), "Invalid Request " + e.toString(), Toast.LENGTH_SHORT).show();
} else if (e instanceof FirebaseTooManyRequestsException) {
Toast.makeText(getBaseContext(), "The SMS quota for the project has been exceeded " + e.toString(), Toast.LENGTH_SHORT).show();
}
}
@Override
public void onCodeSent(String verificationId,
PhoneAuthProvider.ForceResendingToken token) {
// Save verification ID and resending token so we can use them later
verificationid = verificationId;
mresendtoken = token;
Toast.makeText(getBaseContext(), "Code Sent Please Check Your SMS...", Toast.LENGTH_SHORT).show();
AddVerifyButtons();
}
};
