修改你的依赖列表。

依赖关系{ 实现 fileTree(dir: 'libs', include: ['*.jar'])

implementation 'com.google.android.gms:play-services-auth:16.0.1'
implementation 'com.google.android.gms:play-services-base:16.1.0'
implementation 'com.google.android.gms:play-services-location:16.0.1'
implementation 'com.android.support:appcompat-v7:26.1.0'
implementation 'com.android.support.constraint:constraint-layout:1.1.3'
implementation 'com.google.firebase:firebase-auth:16.0.3'
implementation 'com.google.firebase:firebase-core:16.0.1'
implementation 'com.google.android.gms:play-services-maps:16.1.0'
testImplementation 'junit:junit:4.12'
