java - 生成签名的apk时为"Error: Cannot fit requested classes in a single dex file (# methods: 66653 > 65536)"

Question

我正在尝试生成签名的 apk，以便可以将我的应用导出到 Google Play 商店。但是我不断收到同样的错误。有什么办法可以解决这个问题吗？

apply plugin: 'com.android.application'

    android {
        compileSdkVersion 28
        defaultConfig {
            applicationId "com.example.sean.monacoball"
            minSdkVersion 15
            targetSdkVersion 28
            versionCode 1
            versionName "1.0"
            testInstrumentationRunner 
    "android.support.test.runner.AndroidJUnitRunner"
        }
        buildTypes {
            release {
                minifyEnabled false
                proguardFiles getDefaultProguardFile('proguard-android.txt'), 
    'proguard-rules.pro'
            }
        }
    }

    dependencies {
        implementation fileTree(include: ['*.jar'], dir: 'libs')
        implementation 'com.android.support:appcompat-v7:12.0.1'
        implementation 'com.android.support.constraint:constraint-layout:1.1.3'
        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.google.android.gms:play-services:12.0.1'
    }
}

根据 Google Play services setup guide :

Note: Don't use the combined play-services target. It brings in dozens of libraries, bloating your application. Instead, specify only the specific Google Play services APIs your app uses.

当您使用 com.google.android.gms:play-services:12.0.1 时，您将引入所有 Google Play 服务库。您应该切换到仅使用您实际使用的库。这几乎肯定会将您置于 64k method limit 之下单个 dex 文件。
