java - 生成签名的 apk android 时 gcm 出错

Question

我在 android studio 中生成签名的 apk 时遇到错误

Error:Execution failed for task ':AppName:transformClassesWithJarMergingForRelease'.
com.android.build.api.transform.TransformException: java.util.zip.ZipException: duplicate entry: com/google/android/gms/common/internal/zzv$zza$zza.class

Gradle ......

apply plugin: 'com.android.application'

android {
    compileSdkVersion 23
    buildToolsVersion "23.0.1"

defaultConfig {
    applicationId "myApp"
    minSdkVersion 14
    targetSdkVersion 23
    multiDexEnabled true
}

buildTypes {
    release {
        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'
    }
}
dexOptions {
    javaMaxHeapSize "2g"
}

compileOptions {
    sourceCompatibility JavaVersion.VERSION_1_7
    targetCompatibility JavaVersion.VERSION_1_7
}

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

dependencies {
    compile 'org.altbeacon:android-beacon-library:2.1.4'
    compile project(':qRCodeReaderViewlib')
    compile project(':viewpagerindicator')
    compile 'com.android.support:support-v4:23.1.1'
    compile 'com.google.android.gms:play-services-maps:9.0.0'
    compile 'com.android.support:appcompat-v7:23.1.1'
    compile files('libs/android-query-full.0.26.7.jar')
    //compile files('libs/gcm.jar')
    compile files('libs/mint-4.4.0.jar')
    compile 'com.squareup.okhttp3:okhttp:3.2.0'
    compile 'com.android.support:multidex:1.0.1'
    compile 'com.google.firebase:firebase-messaging:9.4.0'
}
// Add to the bottom of the file
apply plugin: 'com.google.gms.google-services'

有什么帮助吗？提前致谢..

您正在使用不同版本的播放服务。这通常会导致错误。请更改

compile 'com.google.android.gms:play-services-maps:9.0.0'

至

 compile 'com.google.android.gms:play-services-maps:9.4.0'
