我正在使用Google翻译API，当我获得发布版本时，会发出以下警告。我搜索了很多示例，但仍然收到此警告。请任何人给我一种解决错误的方法。

在这里我提到我的gradle文件和警告输出。

我的gradle文件： 

  buildTypes {
      release {
          minifyEnabled true
          shrinkResources false
          debuggable false
          proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
     }
  }
   packagingOptions {
      exclude 'META-INF/LICENSE'
      exclude 'META-INF/io.netty.versions.properties'
      exclude 'META-INF/INDEX.LIST'
   }
 }

dependencies {
  implementation fileTree(dir: 'libs', include: ['*.jar'])
  implementation 'com.android.support:appcompat-v7:28.0.0'
  implementation 'com.android.support:design:28.0.0'

  implementation 'com.google.cloud:google-cloud-translate:1.65.0'

  implementation 'com.android.support:recyclerview-v7:28.0.0'
}
    repositories {
       mavenCentral()
}
