java - 包名称为 'com.google.android.gms' 的多个库

Question

我找到了很多关于这个问题的帖子，但没有一个对我有用。这是我的 Gradle:

apply plugin: 'com.android.application'

android {
    compileSdkVersion 23
    buildToolsVersion "23.0.0"

    defaultConfig {
        applicationId "*********"
        minSdkVersion 16
        targetSdkVersion 23
        versionCode 5
        versionName "1.1"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile 'com.android.support:appcompat-v7:23.0.0'
    compile 'com.android.support:cardview-v7:21.0.+'
    compile 'com.android.support:recyclerview-v7:21.0.+'
    compile files('libs/gradle-wrapper.jar')
    compile 'com.facebook.fresco:fresco:0.9.0+'
    compile 'com.facebook.android:audience-network-sdk:4.+'
    compile 'com.google.android.gms:play-services:7.8.0'

}

我不知道问题出在哪里。

你可以想象成一棵树:

gradle -q dependencies yourProject:dependencies --configuration compile

或者在 Windows 上，使用 gradlew

gradlew -q dependencies yourProject:dependencies --configuration compile

示例输出:

compile - Classpath for compiling the main sources.
+--- org.androidannotations:androidannotations-api:3.2
+--- com.android.support:support-annotations:22.1.1
+--- com.squareup:otto:1.3.6
+--- in.srain.cube:grid-view-with-header-footer:1.0.10
+--- com.nostra13.universalimageloader:universal-image-loader:1.9.3
+--- com.github.chrisbanes.photoview:library:1.2.3
+--- org.simpleframework:simple-xml:2.7.1
+--- com.google.android.gms:play-services-base:6.5.+ -> 6.5.87
+--- project :yourProject
|    +--- com.loopj.android:android-async-http:1.4.6
|    +--- org.apache.httpcomponents:httpmime:4.2.5
|    |    \--- org.apache.httpcomponents:httpcore:4.2.4
|    \--- com.google.code.gson:gson:2.3.1
+--- project :facebook
|    \--- com.android.support:appcompat-v7:22.1.1
|         \--- com.android.support:support-v4:22.1.1
|              \--- com.android.support:support-annotations:22.1.1 -> 22.2.0

为避免重复，在每个项目build.gradle中添加exclude

compile('com.github.chrisbanes.photoview:library:1.2.3') {
    exclude group: 'com.android.support'
}
compile('org.simpleframework:simple-xml:2.7.1') {
    exclude module: 'stax'
    exclude module: 'stax-api'
    exclude module: 'xpp3'
}
compile('com.google.android.gms:play-services-base:6.5.+')
        {
            exclude module: 'support-v4'
        }
