尝试删除项目文件夹中的所有构建文件夹,打开项目并使用gradle文件同步项目(它位于android工作室的右上方菜单中)并清理并重建。

从模块级应用程序中删除以下行。

import com.google.gms.googleservices.GoogleServicesPlugin

还要删除buildscript块并再次构建它

你的模块级别gradle文件必须是这样的

apply plugin: 'com.android.application'
... your plugin here

android {
    compileSdkVersion 28
    defaultConfig {
        applicationId "your.application.id"
        minSdkVersion 21
        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-v7:28.0.0'
    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'
..... add more dependencies here
