Android Gaode map configuration and getMap null is empty

1. First download the so library and jar

Official website download address

The version I downloaded is AMap3DMap_5.2.0_AMapNavi_5.1.0_AMapSearch_5.1.0_AMapLocation_3.4.0_20170602.jar

Put the downloaded library in the /app/libs/ directory

2. Configuration permissions

2.1 Configure AndroidManifest.xml

<mainfest ...>
    <!-- 用于访问网络，网络定位需要上网 -->
    <uses-permission android:name="android.permission.INTERNET" />
    <!-- 写入扩展存储，向扩展卡写入数据，用于写入缓存定位数据 -->
    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
    <!-- 用于进行网络定位 -->
    <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
    <!-- 获取运营商信息，用于支持提供运营商信息相关的接口 -->

    <!-- 用于申请获取蓝牙信息进行室内定位 -->
    <uses-permission android:name="android.permission.BLUETOOTH" />
    <uses-permission android:name="android.permission.BLUETOOTH_ADMIN" />
    ......
    <application ...>
<meta-data
            android:name="com.amap.api.v2.apikey"
            android:value="524394a75c01138cf3f095efb781837b" />
        <service android:name="com.amap.api.location.APSService" /><meta-data
            android:name="com.amap.api.v2.apikey"
            android:value="5??????????????????????" />
        <service android:name="com.amap.api.location.APSService" />
</application>


</manifest>

3. Configure build.gradle

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

Notice:

i: mapView .getMap() is null empty

Mainly the third step, not configured

ii: Pay attention to 6.0 permission acquisition
