我是Android新手，我正试图在手机上运行我的应用程序（4.4.2），我收到以下错误：

我正在使用MacBook Pro，我可以在模拟器中运行我的应用程序并且没有出现这些错误，所以我想问题可能是我的手机配置。我也启用了USB调试。我需要在手机上安装任何东西吗？

这是我的app graddle文件：

apply plugin: 'com.android.application'

android {
    compileSdkVersion 25
    buildToolsVersion "25.0.1"
    defaultConfig {
        applicationId "com.example.android.bauthentication"
        minSdkVersion 15
        targetSdkVersion 25
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner  "android.support.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
         }
     }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
        exclude group: 'com.android.support', module: 'support-annotations'
    })
    compile 'com.android.support:appcompat-v7:25.1.0'
    compile 'com.google.android.gms:play-services:10.0.1'
    compile 'com.google.firebase:firebase-core:10.0.1'
    testCompile 'junit:junit:4.12'
    compile 'com.google.firebase:firebase-auth:10.0.1'
}
apply plugin: 'com.google.gms.google-services'

尝试检查配置或查看firebase的文档..

官方网页 - Add Firebase to Your Android Project

小心firebase的版本，存在旧版本和新版本，检查你安装的版本

官方页面旧版本。 Android Quickstart - Firebase

Answer 2

看起来这个问题是由Multidex编译器引起的。您可能需要为版本<21。

的Android手机正确配置您的应用程序

卸载应用并重新安装

如果使用multiDexEnabled false禁用multidex编译器，它应该可以正常工作。
