Java 安卓工作室+；FireBase帐户设置引发错误

我似乎不明白为什么我的程序没有通过帐户注册活动

我的问题发生在这里的某个地方

else if (!(use_email.isEmpty() && use_pass.isEmpty())) {
                    mFirebaseAuth.createUserWithEmailAndPassword( use_email, use_pass).addOnCompleteListener(SignUpActivity.this, new OnCompleteListener<AuthResult>() {
                        @Override
                        public void onComplete(@NonNull Task<AuthResult> task) {

                            if (task.isSuccessful()) {
                                startActivity(new Intent(SignUpActivity.this, LoginFormActivity.class));
                            }
                            else {
               //My problem happens Here
                 Toast.makeText(SignUpActivity.this, "Account Setup Error", Toast.LENGTH_SHORT).show();

build.gradle

// Top-level build file where you can add configuration options common to all sub-projects/modules.
buildscript {
    repositories {
        google()
        jcenter()
    }
    dependencies {
        classpath "com.android.tools.build:gradle:4.1.2"
        classpath 'com.google.gms:google-services:4.3.5'
        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        google()
        jcenter()
    }
}

task clean(type: Delete) {
    delete rootProject.buildDir
}

也许是版本的问题。使用此版本

---

实施平台（'com.google.firebase:firebase bom:26.4.0'）

确保您必须在firebase控制台中启用电子邮件和密码作为登录方法，并且如果您使用的是实施平台（'com.google.firebase:firebase bom:26.5.0'）

那么您就不需要为以下内容定义版本： 实现'com.google.firebase:firebase auth:19.3.1'

bom表自动采用最新版本 替换将是：

implementation'com.google.firebase:firebase auth

感谢您的回复！我做了更改，但不幸的是，结果是一样的。感谢您的回复，我在firebase控制台上启用了电子邮件/密码。
