您好，我正在学习使用Udacity课程中的Firebase。当我运行我的应用程序并且对此没有任何线索时，我收到此错误。 11-23 16：48：34.995 3947-3947 / com.google.firebase.udacity.friendlychat

任何人都可以帮助我吗？

更新build.gradle

apply plugin: 'com.android.application'

repositories {
    mavenLocal()
    maven { url 'https://maven.fabric.io/public' }
    flatDir {
        dirs 'libs'
    }
}

android {
    compileSdkVersion 24
    buildToolsVersion "24.0.1"

    defaultConfig {
        applicationId "com.google.firebase.udacity.friendlychat"
        minSdkVersion 16
        targetSdkVersion 24
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
    packagingOptions {
        exclude 'META-INF/LICENSE'
        exclude 'META-INF/LICENSE-FIREBASE.txt'
        exclude 'META-INF/NOTICE'
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    testCompile 'junit:junit:4.12'

    compile 'com.android.support:design:24.2.0'
    compile 'com.android.support:appcompat-v7:24.2.0'

    // Displaying images
    compile 'com.github.bumptech.glide:glide:3.6.1'
// Firebase
    compile 'com.google.firebase:firebase-database:10.0.0'
    compile 'com.firebaseui:firebase-ui-database:1.0.0'

    // FirebaseUI Auth only
    compile 'com.firebaseui:firebase-ui-auth:1.0.0'

    // FirebaseUI Storage only
    compile 'com.firebaseui:firebase-ui-storage:1.0.0'

    // Single target that includes all FirebaseUI libraries above
    compile 'com.firebaseui:firebase-ui:1.0.0'

    // Firebase Auth
    compile 'com.google.firebase:firebase-auth:10.0.0'

}

Answer 1

匹配版本解决了这个问题。在与Firebase / Google Play服务库的兼容性中，它与

匹配

$( "#button" ).click(function() {
$( "#square" ).animate({
left: "-=60px",
}, 400);
});

因此，如果依赖关系更改为

FirebaseUI Version   Firebase/Play Services Version

   1.0.0                   9.8.0

而不是

compile 'com.google.firebase:firebase-database:9.8.0'
compile 'com.google.firebase:firebase-auth:9.8.0'
compile 'com.firebaseui:firebase-ui-auth:1.0.0'

这是firebaseUI版本的最新可用firebase版本，应用程序正常

Answer 2

这很可能与Firebase和FirebaseUI之间的版本不兼容有关。我遇到了同样的问题，并花了30-45分钟试图找出它。最终我为了继续使用“周末的Firebase”教程而做的是：

git checkout 1.04-firebase-auth-firebaseui-signin

这将在本教程的这一点切换到分支。这样做后效果很好。

对于问题是什么，也许不是理想的答案，但会让你再次参加课程。

Answer 3

你只需要添加： 编译com.google.android.gms：play-services-auth：x.x.x＆＃39; （找到合适的版本here）。他们错过了说你还需要为google身份验证添加play-services-auth依赖关系。
