集成 firebase 通知后无法在设备中安装应用程序

Question

我添加了这些行以将 firebase 通知集成到我的应用程序

build.gradle(模块:应用程序)

apply plugin: 'com.android.appname'

android {
compileSdkVersion 25
buildToolsVersion "25.0.2"
defaultConfig {
    applicationId "com.example.app"
    minSdkVersion 15
    targetSdkVersion 25
    versionCode 1
    versionName "1.0"
    testInstrumentationRunner 
    "android.support.test.runner.AndroidJUnitRunner"
    multiDexEnabled true

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

dependencies {
compile fileTree(dir: 'libs')
compile 'com.android.support:design:25.3.1'
compile 'com.android.support:cardview-v7:25.3.1'
compile 'com.android.support:appcompat-v7:25.3.1'
compile 'com.facebook.android:facebook-android-sdk:[4,5)'
compile 'com.facebook.android:audience-network-sdk:4.21.1'
compile 'com.google.firebase:firebase-messaging:10.0.1'
}
apply plugin: 'com.google.gms.google-services'

build.gradle(项目:appName)

 buildscript {
    repositories {
       jcenter()
 }
 dependencies {
    classpath 'com.android.tools.build:gradle:2.3.1'
    classpath 'com.google.gms:google-services:3.0.0'
   }
 }

 allprojects {
    repositories {
       jcenter()
     }
  }

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

如果我在添加这些依赖项后尝试运行应用程序，则会显示以下错误：

Error:Execution failed for task ':app:transformClassesWithJarMergingForDebug'.> com.android.build.api.transform.TransformException: java.util.zip.ZipException: duplicate entry: com/google/android/gms/internal/zzcn$zza.class

Answer 1

依赖报告显示 audience-network-sdk 对 com.google.android.gms:play-services-ads:8.4.0 有传递依赖。这就是冲突的根源。

我不使用 Facebook 库，不确定最佳解决方案。这两个选项都将允许您构建。我不知道是否每个人都会支持你的代码。您必须进行试验：

选项 1：

compile 'com.facebook.android:facebook-android-sdk:[4,5)'
compile ('com.facebook.android:audience-network-sdk:4.21.1', {
    exclude group: 'com.google.android.gms', module: 'play-services-ads'
})
compile 'com.google.firebase:firebase-messaging:10.0.1'

选项 2：

compile 'com.facebook.android:facebook-android-sdk:[4,5)'
compile 'com.facebook.android:audience-network-sdk:4.21.1'
compile 'com.google.firebase:firebase-messaging:10.0.1'
compile 'com.google.android.gms:play-services-ads:10.0.1'

Answer 2

尝试在 buildTypes

之后的 build.gradle 中添加 packagingOptions

包装选项代码

 packagingOptions {
        exclude 'META-INF/LICENSE'
        exclude 'META-INF/LICENSE-FIREBASE.txt'
        exclude 'META-INF/NOTICE'

    }

编辑代码

apply plugin: 'com.android.appname'

android {
compileSdkVersion 25
buildToolsVersion "25.0.2"
defaultConfig {
    applicationId "com.example.app"
    minSdkVersion 15
    targetSdkVersion 25
    versionCode 1
    versionName "1.0"
    testInstrumentationRunner 
   "android.support.test.runner.AndroidJUnitRunner"
    multiDexEnabled true

}
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')
compile 'com.android.support:design:25.3.1'
compile 'com.android.support:cardview-v7:25.3.1'
compile 'com.android.support:appcompat-v7:25.3.1'
compile 'com.facebook.android:facebook-android-sdk:[4,5)'
compile 'com.facebook.android:audience-network-sdk:4.21.1'
compile 'com.google.firebase:firebase-messaging:10.0.1'
}
apply plugin: 'com.google.gms.google-services'
