所有com.android.support库都必须使用完全相同的版本规范：27.0.2

问题描述

将targetSdkVersion更新为27后，我收到此错误消息。

After updating targetSdkVersion to 27 I got this error message.

我知道我应该更新 com.android.support： support-media-compat 但我不知道怎么做，因为我没有在build.gradle中使用它，我试图更新SDK工具，但问题仍然存在。波纹管是build.gradle：

I understand that I should update com.android.support:support-media-compat but I dont know how because I am not using it in build.gradle , I tried to update SDK tools but the problem is still remaining . bellow is build.gradle:

    apply plugin: 'com.android.application'

android {
    compileSdkVersion 27
    defaultConfig {
        applicationId "com.example.ex"
        minSdkVersion 16
        targetSdkVersion 27
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled true
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    implementation fileTree(include: ['*.jar'], dir: 'libs')
    implementation 'com.android.support:appcompat-v7:27.0.2'
    implementation 'com.android.support.constraint:constraint-layout:1.0.2'
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'com.android.support.test:runner:1.0.1'
    androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.1'
    implementation 'com.google.android.gms:play-services-ads:11.6.2'
    compile 'com.android.volley:volley:1.0.0'
    compile 'com.squareup.picasso:picasso:2.5.2'
    compile 'com.github.bloder:magic:1.1'
    implementation 'com.android.support:recyclerview-v7:27.0.2'
    implementation 'com.android.support:cardview-v7:27.0.2'
}

推荐答案

我已经手动检查了项目中的库-> .myidea->库，然后发现我有两个使用旧版本的库：

I have checked manually the libraries in project -> .myidea-> libraries then I found that I have two libraries using the old version :

然后只需在builde.gradle中添加此行

then just by adding this line in builde.gradle

错误现在消失了。
