android {
compileSdkVersion 25
buildToolsVersion '27.0.3'
defaultConfig {
    applicationId "com.example.christinebpolesti.busartery_driver"
    minSdkVersion 16
    targetSdkVersion 25
    versionCode 1
    versionName "1.0"
    multiDexEnabled true
    testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}
dependencies {
implementation fileTree(dir: 'libs', include: ['*.jar'])
implementation 'com.android.support.constraint:constraint-layout:1.1.0'
testImplementation 'junit:junit:4.12'
androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'

implementation 'com.android.support:design:25.2.0'

}
apply plugin: 'com.google.gms.google-services'

前几天工作正常，我不知道发生了什么。我甚至卸载并再次安装android studio因为在此问题之前我的adb没有找到..所以在再次安装AS之后，我遇到了这个问题。有人可以帮忙吗。

Answer 1

打开您的build.gradle应用并粘贴此代码：

implementation 'com.google.android.gms:play-services-maps:15.0.1'

Answer 2

这是因为

OnMapReadyCallback

是包

的接口

com.google.android.gms.maps

因此您必须包含此程序包的依赖项才能使用此界面

此程序包还附带Latlng,GoogleMap
