实现 Firebase 电话身份验证时出现 UserCancellationException

Question

I am having a problem trying to implement the Firebase phone Authentication for the first time,I am using the FirebaseUI to do this,but every time I run the App on my phone (Huewei y9 2019) and put my number and click on the verify phone number I get a null response without pressing the back button and it keeps sending me back to the sign in page.

I have read the documentation and many subjects about implementing the phone Authentication through the FirebaseUI and I have done all the steps including adding the phone in my method in my Firebase Authentication SignIn methods,adding the SHA-1 and SHA-256 to my Firebase project,Downloading the Google-Services.json file and adding it to my project and also I tried enabling/disenabling the Android Device Check API to enable the Safteynet for my app but nothing changes.

I got to say that tried to implement Google,Twitter and Email authentication using the FirebaseUI and everything is working fine except for the Phone Authentication.

I hope to find someone that can help me to understand this problem and solve it.

Here is my Main Activity code:

package com.development.myfirebaseapp;

import androidx.annotation.NonNull;
import androidx.appcompat.app.AppCompatActivity;
import androidx.constraintlayout.widget.ConstraintLayout;
import androidx.constraintlayout.widget.ConstraintSet;
import android.annotation.SuppressLint;
import android.content.Context;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.Toast;
import com.firebase.ui.auth.AuthUI;
import com.firebase.ui.auth.IdpResponse;
import com.google.android.gms.tasks.OnCompleteListener;
import com.google.android.gms.tasks.Task;
import com.google.firebase.auth.FirebaseAuth;
import com.google.firebase.auth.FirebaseUser;
import java.util.Arrays;
import java.util.List;



public class MainActivity extends AppCompatActivity {

final Context context = this;

List<AuthUI.IdpConfig> providers;

private final static int SIGN_IN_INTENT_REQUESTCODE = 1;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    createSignInMethods();
}

public void createSignInMethods()
{
            providers = Arrays.asList(
            new AuthUI.IdpConfig.PhoneBuilder().build(),
            new AuthUI.IdpConfig.EmailBuilder().build(),
            new AuthUI.IdpConfig.GoogleBuilder().build(),
            new AuthUI.IdpConfig.TwitterBuilder().build());

    startActivityForResult(AuthUI.getInstance().createSignInIntentBuilder()
            .setAvailableProviders(providers)
            .build(), SIGN_IN_INTENT_REQUESTCODE);

}

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data)
{
    super.onActivityResult(requestCode,resultCode,data);

    if(requestCode == SIGN_IN_INTENT_REQUESTCODE)
    {
        IdpResponse response = IdpResponse.fromResultIntent(data);

        if(resultCode == RESULT_OK)
        {
            FirebaseUser user = FirebaseAuth.getInstance().getCurrentUser();

            Toast.makeText(context,"Successfully signed in",Toast.LENGTH_SHORT).show();

        }
        else
        {
            int errorCode = response.getError().getErrorCode();

            Log.d("authErrorCode",String.valueOf(errorCode));

            Toast.makeText(context,"Failed to sign in",Toast.LENGTH_SHORT).show();
        }
    }
 }
    
}

And here is my App Build.gradle file:

apply plugin: 'com.android.application'
apply plugin: 'com.google.gms.google-services'

android {
compileSdkVersion 29
buildToolsVersion "29.0.2"

defaultConfig {
    applicationId "com.development.myfirebaseapp"
    minSdkVersion 18
    targetSdkVersion 29
    versionCode 1
    versionName "1.0"

    testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
}

buildTypes {
    release {
        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
    }
 }

}

dependencies {
implementation fileTree(dir: 'libs', include: ['*.jar'])

implementation 'androidx.appcompat:appcompat:1.2.0'
implementation 'androidx.constraintlayout:constraintlayout:2.0.4'
testImplementation 'junit:junit:4.12'
androidTestImplementation 'androidx.test.ext:junit:1.1.2'
androidTestImplementation 'androidx.test.espresso:espresso-core:3.3.0'

implementation platform('com.google.firebase:firebase-bom:26.5.0')
implementation 'com.firebaseui:firebase-ui-auth:6.4.0'
implementation 'com.twitter.sdk.android:twitter-core:3.1.1'
}

Finally here is my log file:

Answer 1

Just in case anyone faced this problem again I updated the Firebase Bom to the latest version (26.6.0) and the FirebaseUI Auth to version (7.1.1) and finally my problem solved
