Firebase Firestore Dependency配置问题

Question

我面临添加Firestore依赖项的问题。 任何类型的Firestore依赖项都会产生错误，最后发生事件。 在添加此依赖项应用程序后，当前依赖项com.google.firebase:firebase-firestore:17.1.2在这里没有运行，我也尝试firesrore： 16.0.0 and firestore:15:0.1但没有任何作用。

implementation fileTree(dir: 'libs', include: ['*.jar'])
//noinspection GradleCompatible
implementation 'com.android.support:appcompat-v7:27.1.1'
implementation 'com.android.support.constraint:constraint-layout:1.1.3'
implementation 'com.android.support:support-v4:27.1.1'
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'

// FireBase
//noinspection GradleCompatible
**implementation 'com.google.firebase:firebase-core:16.0.1'**

/*[This line create Error but i need firestore]*/ 
implementation 'com.google.firebase:firebase-firestore:17.1.2'

// Audience Network
implementation 'com.android.support:recyclerview-v7:27.1.1'
// Required Dependency by Audience Network SDK
implementation 'com.facebook.android:audience-network-sdk:5.+'

// admob ad dependency
implementation 'com.google.android.gms:play-services-ads:15.0.1'

// Tappx ad Dependency
implementation 'com.tappx.sdk.android:tappx-sdk:3.+'
implementation 'com.google.android.gms:play-services-base:15.0.1'
