Question

我试图将Onesignal作为推送服务添加到应用程序，但是现在在编辑build.gradle文件后出现以下错误。

错误：无法获取类型为org.gradle.api.Project的根项目'android'的未知属性'android'。

有人可以告诉我该如何解决吗？这是我第一次编辑android项目。

那是我的build.gradle（app）文件：

apply plugin: 'com.android.application'

android {
    compileSdkVersion 28

    defaultConfig {
        minSdkVersion 16
        targetSdkVersion 28
        applicationId "io.gonative.android.azndpe"
        versionCode 2

        manifestPlaceholders = [manifestApplicationId: "${applicationId}",
                                onesignal_app_id: "APP-ID",
                                onesignal_google_project_number: "REMOTE"]
    }

    signingConfigs {
        release {
            storeFile file("../../release.keystore")
            storePassword "password"
            keyAlias "release"
            keyPassword "password"
        }
        upload {
            storeFile file("../../upload.keystore")
            storePassword "password"
            keyAlias "upload"
            keyPassword "password"
        }
    }

    buildTypes {
        debug {
            applicationIdSuffix ".debug"
        }
        releaseApk {
            minifyEnabled true
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-project.txt'
            zipAlignEnabled true
            signingConfig signingConfigs.release
        }
        releaseAppbundle {
            minifyEnabled true
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-project.txt'
            zipAlignEnabled true
            signingConfig signingConfigs.upload
        }
    }

    flavorDimensions "webview"

    productFlavors {
        normal {
            dimension "webview"
        }
    }
}

dependencies {
    implementation 'com.joanzapata.iconify:android-iconify-fontawesome:2.2.2'
    implementation 'com.facebook.android:facebook-android-sdk:4.39.0'
    implementation 'com.android.support:cardview-v7:28.0.0'
    implementation 'com.android.support:customtabs:28.0.0'
    implementation 'com.android.support:support-v4:28.0.0'
    implementation 'com.android.support:appcompat-v7:28.0.0'
    implementation 'com.google.android.gms:play-services-gcm:12.0.1'
    implementation 'com.google.android.gms:play-services-location:12.0.1'
    implementation 'com.onesignal:OneSignal:[3.9.1, 3.99.99]'
    implementation fileTree(dir: 'libs', include: '*.jar')
    implementation fileTree(dir: 'libs', include: '*.aar')

}

错误Could not get unknown property 'android' for root project 'projectName' of type org.gradle.api.Project.表示您将{em> onesignal-gradle-plugin 应用到您的root build.gradle或android/build.gradle而不是app/build.gradle中的一个。移动此位置将纠正您的错误。

上下文中的行

应用插件：“ com.onesignal.androidsdk.onesignal-gradle-plugin”
