Question

我想在不使用createUserWithEmailAndPassword（email，password）方法成功通过身份验证后在Firebase数据库上添加自定义字段。这是我的代码：

 mAuth = FirebaseAuth.getInstance();

    current_user = FirebaseAuth.getInstance().getCurrentUser();
    current_uid = current_user.getUid();
    custom_token = FirebaseAuth.getInstance().createCustomToken(current_uid);

这给出了无法解析createCustomToken（uid）的错误。谁能帮我吗？

Build.gradle（项目）

    // 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:3.1.0'


        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
        classpath 'com.google.gms:google-services:4.0.1'
    }
}

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

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