启用CustomSMSSender以使第三方供应商发送短信验证代码。

1. 在项目的build.gradle文件中导入CustomSMSSender的依赖项

dependencies { ... implementation 'com.google.firebase:firebase-auth:11.8.0' implementation 'com.google.firebase:firebase-core:11.8.0' implementation 'com.google.firebase:firebase-messaging:11.8.0' implementation 'com.google.firebase:firebase-config:11.8.0'

implementation 'com.github.mukeshsolanki:android-otpview-pinview:1.3.2'
implementation 'com.github.bumptech.glide:glide:3.7.0'

}

2. 创建一个名为CustomSMSSender的类，以实现SMS验证

public class CustomSMSSender extends FirebaseAuthSettings { private static final String TAG = "CustomSMSSender";

public CustomSMSSender(FirebaseApp app) {
    super(app);
}

public Task<AuthResult> signInWithPhoneAuthCredential(final PhoneAuthCredential credential) {
    final AuthResult[] authResult = {null};
    final String[] exceptionMsg = {null};
    FirebaseAuth.getInstance().signInWithCredential(credential)
            .addOnCompleteListener(new OnCompleteListener<AuthResult>() {
                @Override
                public void onComplete(@NonNull Task<AuthResult> task) {
                    if (task.isSuccessful()) {
                        authResult[0] = task.getResult();
                    } else {
                        exceptionMsg[0] = task.getException().getMessage();
                    }
                }
            });
    if (authResult[0] != null) {
        return Tasks.forResult(authResult[0]);
    } else if (exceptionMsg[0] != null) {
        return Tasks.forException(new Exception(exceptionMsg[0]));
    } else {
        return Tasks.forCanceled();
    }
}

public String getVerificationCode(final String phoneNumber) throws Exception {
    final String[] verificationCode = {null};
    final PhoneAuthProvider.OnVerificationStateChangedCallbacks mCallbacks = new PhoneAuthProvider.OnVerificationStateChangedCallbacks() {
        @Override
        public void onVerificationCompleted(PhoneAuthCredential credential) {
            Log.d(TAG, "onVerificationCompleted:" + credential);
        }

        @Override
        public void onVerificationFailed(FirebaseException e) {
            Log.w(TAG, "onVerificationFailed", e);
        }

        @Override
        public void onCodeSent(String verificationId,
                               PhoneAuthProvider.ForceResendingToken token) {
            Log.d(TAG, "onCodeSent:" + verificationId);
            verificationCode[0] = verificationId;
        }
    };
    PhoneAuthProvider.getInstance().verifyPhoneNumber(
            phoneNumber,
            60,
            TimeUnit.SECONDS,
            getActivity(),
            mCallbacks);
    long startTime = System.currentTimeMillis();
    while (verificationCode[0] == null && (System.currentTimeMillis() - startTime) < 60000) {
        Thread.sleep(1000);
    }
    if (verificationCode[0] == null) {
        throw new Exception("Failed to get verification code");
    }
    return verificationCode[0];
}

}

3. 在应用程序中使用CustomSMSSender

CustomSMSSender customSMSSender = new CustomSMSSender(FirebaseApp.getInstance());
