Question

我已尝试将Onesignal实施到我的Android项目中，但我有关于Firebase的错误：

无法解决：com.google.firebase：firebase-messaging：15.0.1

我在文档中做了所有事情：https://documentation.onesignal.com/docs/android-sdk-setup#section-android-studio

这是我的build.gradle

    buildscript {
    repositories {
        maven { url 'https://plugins.gradle.org/m2/'}
    }
    dependencies {
        classpath 'gradle.plugin.com.onesignal:onesignal-gradle-plugin:[0.9.0, 0.99.99]'
    }
}
apply plugin: 'com.onesignal.androidsdk.onesignal-gradle-plugin'

repositories {
    maven { url 'https://maven.google.com' }
}

apply plugin: 'com.android.application'

android {
    compileSdkVersion 27
    defaultConfig {
        applicationId "com.my.package"
        manifestPlaceholders = [
                onesignal_app_id: 'XXXXXX-1b8c-48d3-a596-d277fad80edc',
                // Project number pulled from dashboard, local value is ignored.
                onesignal_google_project_number: 'XXX921710280' ]
        minSdkVersion 16
        targetSdkVersion 27
        versionCode 2
        versionName "v2.2"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled true
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    implementation fileTree(include: ['*.jar'], dir: 'libs')
    implementation 'com.android.support:appcompat-v7:27.1.1'
    implementation 'com.android.support:recyclerview-v7:27.1.1'
    implementation 'com.android.support:cardview-v7:27.1.1'
    implementation 'com.android.support:support-v4:27.1.1'
    implementation 'com.android.support:customtabs:27.1.1'
    implementation 'com.android.support.constraint:constraint-layout:1.1.0'

    implementation 'com.google.android.gms:play-services-ads:15.0.1'
    compile 'com.android.volley:volley:1.0.0'
    compile 'com.github.simbiose:Encryption:2.0.1'
    compile 'com.squareup.picasso:picasso:2.5.2'
    compile 'com.scottyab:aescrypt:0.0.1'
    compile 'com.github.bloder:magic:1.1'
    compile 'com.onesignal:OneSignal:3.9.1'
}

Answer 1

在 build.gradle ：

添加：

jcenter()

在repositories
