Question

我正在尝试使用Carto Mobile SDK，但Android Studio会告诉我Unresolved reference: com.carto.ui.MapView。

我有最新的Android Studio Canary，我更新了gradle和kotlin插件，但仍无效。

这只发生在Android Studio 3.0 Canary中，适用于Android Studio 2.3.3。

这些是我的gradle文件：

Project gradle：

buildscript {
    ext.kotlin_version = '1.1.3'
    ext.anko_version = '0.10.1'

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

    dependencies {
        classpath 'com.android.tools.build:gradle:3.0.0-alpha5'
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
    }
}

allprojects {
    repositories {
        maven { url 'https://maven.google.com' }
        jcenter()
        mavenCentral()
    }
}

task clean(type: Delete) {
    delete rootProject.buildDir
}

App gradle：

apply plugin: 'com.android.application'

apply plugin: 'kotlin-android'
apply plugin: 'kotlin-android-extensions'

android {
    compileSdkVersion 25
    buildToolsVersion "25.0.2"
    defaultConfig {
        applicationId "me.mcordoba.test"
        minSdkVersion 16
        targetSdkVersion 25
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])

    androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
        exclude group: 'com.android.support', module: 'support-annotations'
    })

    compile "org.jetbrains.kotlin:kotlin-stdlib-jre7:$kotlin_version"
    compile "org.jetbrains.anko:anko-commons:$anko_version"

    compile 'com.android.support:appcompat-v7:25.4.0'
    compile 'com.android.support:support-v4:25.4.0'
    compile 'com.android.support.constraint:constraint-layout:1.0.2'

    compile 'com.carto:carto-mobile-sdk:4.0.2@aar'

    testCompile 'junit:junit:4.12'
}

Answer 1

1.将classpath a[i]=0添加到项目gradle的 buildscript-dependencies

2.添加org.jetbrains.kotlin:kotlin-android-extensions:$kotlin_version 在apply plugin: 'kotlin-android' app gradle之后apply plugin: 'kotlin-android-extensions'。

对我来说，它发生在Android studio 3.1上。

Android Studio 3 Canary中未解决的引用
