成功构建gradle之后，更新Google Service插件并且无法安装应用

Question

我正在使用将Firebase数据库用于数据存储的Android应用程序，但问题是当成功构建后无法安装应用程序时。  

这是Gradle 中的错误图片

这是Build.gradle的代码

dependencies {
implementation fileTree(dir: 'libs', include: ['*.jar'])
implementation 'com.android.support:appcompat-v7:27.1.1'
implementation 'com.android.support.constraint:constraint-layout:1.1.2'
implementation 'com.google.firebase:firebase-core:11.8.0'
implementation 'com.google.firebase:firebase-messaging:11.8.0'
implementation 'com.google.firebase:firebase-auth:11.8.0'
implementation 'com.google.firebase:firebase-database:11.8.0'
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.android.support:recyclerview-v7:27.1.1'
implementation 'com.android.support:gridlayout-v7:27.1.1'
implementation 'com.google.android.gms:play-services-maps:15.0.1'
implementation 'com.google.android.gms:play-services-ads:15.0.1'
implementation 'com.android.support:design:27.1.1'
implementation 'com.android.support:cardview-v7:27.1.1'

}

Answer 1

请尝试此操作，将27.1.1替换为26.1.0

implementation 'com.android.support:appcompat-v7:26.1.0'
implementation 'com.android.support:cardview-v7:26.1.0'
implementation 'com.android.support:design:26.1.0'
implementation 'com.android.support:recyclerview-v7:26.1.0'
implementation 'com.android.support:gridlayout-v7:26.1.0'

Answer 2

将firebase库更新为以下内容：

implementation 'com.google.firebase:firebase-core:16.0.1'
implementation 'com.google.firebase:firebase-messaging:17.1.0'
implementation 'com.google.firebase:firebase-auth:16.0.2'
implementation 'com.google.firebase:firebase-database:16.0.1'

并在顶级gradle文件中使用：

classpath 'com.google.gms:google-services:4.0.2'
