添加移动广告SDK后应用程序停止同步

Question

我的应用程序运行良好，但添加了移动广告SDK后，它就停止了同步。

apply plugin: 'com.android.application'

android {
    compileSdkVersion 28
    defaultConfig {
        applicationId "abc
        minSdkVersion 16
        targetSdkVersion 28
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
        vectorDrawables.useSupportLibrary = true
    }
    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
    }

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

    sourceSets {
        main {
            assets.srcDirs = ['src/main/assets', 'src/main/assets/images', 'src/main/assets/databases'] 
            res.srcDirs =['src/main/res', 'src/main/res/menu', 'src/main/res/anim', 'src/main/res/values-ja']
        }
    }
}

dependencies {
    implementation fileTree(include: ['*.jar'], dir: 'libs')
    implementation 'com.android.support:appcompat-v7:28.0.0-rc02'
    implementation 'com.android.support.constraint:constraint-layout:1.1.3'
    implementation 'com.android.support:support-v4:28.0.0'
    implementation 'com.android.support:support-vector-drawable:28.0.0'
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'com.android.support.test:runner:1.0.2'
    androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'
    implementation 'com.sothree.slidinguppanel:library:3.4.0'
    implementation 'com.squareup.picasso:picasso:2.71828'
    implementation 'com.readystatesoftware.sqliteasset:sqliteassethelper:+'
    implementation 'com.google.android.gms:play-services-ads:17.1.1'
}

这就是错误所在。

清单合并失败：[com.android.support:RecyclerView-V7:26.0.2]AndroidManifest.xml:25:13-35中的属性元数据#android.support.version@Value Value=(26.0.2)也出现在[com.android.support:CustomTabs:26.1.0]AndroidManifest.xml:25:13-35 Value=(26.1.0)中。建议：将'tools:replace=“android:value”‘添加到AndroidManifest.xml:23:9-25:38处的元素以覆盖。

不知道错误是什么意思，有没有人遇到过同样的问题？

Answer 1

问题：

问题是支持库版本冲突。

解决方案：

implementation "com.android.support:appcompat-v7:$supportLibraryVersion"
implementation "com.android.support:support-v4:$supportLibraryVersion"
