Question

我尝试将我的应用程序连接到firebase数据库，以便从使用recyclerview和cardview显示的firebase接收数据列表，但添加依赖项时有很多错误运行app时出现此错误。

第一个错误 -

Error:Execution failed for task ':app:transformClassesWithJarMergingForDebug'. > com.android.build.api.transform.TransformException: java.util.zip.ZipException: duplicate entry: com/google/firebase/iid/zzc.class

这是我的应用程序构建gradle

android {
compileSdkVersion 23
buildToolsVersion "23.0.0"

defaultConfig {
    applicationId "com.seu.hh.mm"
    minSdkVersion 14
    targetSdkVersion 26
    versionCode 1
    versionName "1.0"
    multiDexEnabled true

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


dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    testCompile 'junit:junit:4.12'
    compile 'com.android.support:appcompat-v7:23.0.0'

    compile 'com.google.firebase:firebase-core:10.0.1'
    compile 'com.google.firebase:firebase-database:10.0.1'
    compile 'com.firebase:firebase-client-android:2.4.0'
    compile 'com.google.firebase:firebase-crash:10.0.1'
    compile 'com.google.firebase:firebase-storage:10.0.1'
    compile 'com.android.support:recyclerview-v7:23.0.0'
    compile 'com.android.support:cardview-v7:23.0.0'

    compile 'com.squareup.picasso:picasso:2.5.2'
    compile 'com.android.support:support-v4:23.0.0'
    compile 'com.firebaseui:firebase-ui-database:2.1.1'

}


packagingOptions {
    exclude 'META-INF/DEPENDENCIES.txt'
    exclude 'META-INF/LICENSE.txt'
    exclude 'META-INF/NOTICE.txt'
    exclude 'META-INF/NOTICE'
    exclude 'META-INF/LICENSE'
    exclude 'META-INF/DEPENDENCIES'
    exclude 'META-INF/notice.txt'
    exclude 'META-INF/license.txt'
    exclude 'META-INF/dependencies.txt'
    exclude 'META-INF/LGPL2.1'
}
}

apply plugin: 'com.google.gms.google-services'

这是我的构建gradle项目

 allprojects {
repositories {
    maven {
        url "https://maven.google.com"
    }
    jcenter()
}

   }

   buildscript {
repositories {
    jcenter()
}
dependencies {
    classpath 'com.android.tools.build:gradle:1.5.0'
    classpath 'com.google.gms:google-services:3.1.0'


}
}

allprojects {
repositories {
    jcenter()
}
}

请帮帮我:(
如何解决这个问题并让app运行

Answer 1

您正在将compile 'com.firebaseui:firebase-ui-database:2.1.1'与compile 'com.google.firebase:firebase-database:10.0.1'混合在一起，这就是您复制的原因。

首先，您需要删除这行代码：

compile 'com.firebaseui:firebase-ui-database:2.1.1'

更改以下代码行：

compile 'com.android.support:appcompat-v7:23.0.0'
compile 'com.google.firebase:firebase-core:10.0.1'
compile 'com.google.firebase:firebase-database:10.0.1'
compile 'com.google.firebase:firebase-crash:10.0.1'
compile 'com.google.firebase:firebase-storage:10.0.1'
compile 'com.android.support:recyclerview-v7:23.0.0'
compile 'com.android.support:cardview-v7:23.0.0'

与

compile 'com.android.support:appcompat-v7:25.3.1'
compile 'com.google.firebase:firebase-core:11.0.1'
compile 'com.google.firebase:firebase-database:11.0.1'
compile 'com.google.firebase:firebase-crash:11.0.1'
compile 'com.google.firebase:firebase-storage:11.0.1'
compile 'com.android.support:recyclerview-v7:25.3.1'
compile 'com.android.support:cardview-v7:25.3.1'

通过这种方式，您将拥有lates版本。

运行app
