我无法在我的 android 应用程序中加载地图平台，只显示徽标

Question

我想在我的 android 应用中使用 Neshan 地图平台。但地图不会加载到模拟器上，只显示徽标。

这是清单文件：

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
          package="com.example.neshantest2">

    <uses-permission android:name="android.permission.INTERNET"/>

    <application
            android:usesCleartextTraffic="true"
            android:allowBackup="true"
            android:icon="@mipmap/ic_launcher"
            android:label="@string/app_name"
            android:roundIcon="@mipmap/ic_launcher_round"
            android:supportsRtl="true"
            android:theme="@style/AppTheme"
            android:hardwareAccelerated="true">
        <activity android:name=".routing.MainActivity">
            <intent-filter>
                <action android:name="android.intent.action.MAIN"/>

                <category android:name="android.intent.category.LAUNCHER"/>
            </intent-filter>
        </activity>
    </application>

</manifest>

这是 gradle 项目级别： 顶级构建文件，您可以在其中添加所有子项目/模块通用的配置选项。

buildscript {
    ext.kotlin_version = '1.3.21'
    repositories {
        google()
        jcenter()

    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.3.2'
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        google()
        jcenter()
        maven { url "https://dl.bintray.com/neshan/neshan-android-sdk" }

    }
}

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

这是 gradle 模块级别
