1.解压下载的压缩包，找到AMap_Android_SDK_All\AMap3DMap_DemoDocs\AMap_Android_API_3DMap_Demo\AMap3DDemo\app\libs，复制libs里的所有文件，将其粘贴到Android工程的libs目录下，如图所示。

2.打开app下的build.gradle，添加下述脚本，添加完脚本后，点击Sync Now。

sourceSets {
        main {
            jniLibs.srcDirs = ['libs']
        }
    }

implementation fileTree(dir: 'libs', include: ['*.jar'])

3.sync完成后，参照demo，修改AndroidManifest.xml

添加user-permission

    <uses-permission android:name="android.permission.INTERNET" />
    <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
    <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
    <uses-permission android:name="android.permission.CHANGE_WIFI_STATE" />
    <uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
    <uses-permission android:name="android.permission.WAKE_LOCK" />
    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
    <!--声明后台定位权限-->
    <uses-permission android:name="android.permission.ACCESS_BACKGROUND_LOCATION" />

添加key

        <meta-data
            android:name="com.amap.api.v2.apikey"
            android:value="您的key" />

4.修改layout，在layout中添加map

<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".MainActivity">

    <com.amap.api.maps.MapView
        android:id="@+id/map"
        android:layout_width="0dp"
        android:layout_height="0dp"
        app:layout_constraintBottom_toBottomOf="parent"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintTop_toTopOf="parent"/>

</androidx.constraintlayout.widget.ConstraintLayout>

5.修改MainActivity.java代码

public class MainActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        MapView mapView = (MapView) findViewById(R.id.map);
        mapView.onCreate(savedInstanceState);// 此方法必须重写
        AMap aMap = mapView.getMap();
    }
}

6.运行App，查看运行结果
