Map of Gaode, locate

 

After downloading, unzip and import the jar package, then create and import it in main, as shown in the following figure

and then download the SDK according to the same steps;

! ! Remember to download the download, do not import two jars at a time, if there is no conflict, my blood lesson, one day summary

will also import the jar package;

then configure in the manifest file :

复制代码

<application
         android:icon="@drawable/icon"
         android:label="@string/app_name" >
         <meta-data
            android:name="com.amap.api.v2.apikey"
            android:value="请输入您的用户Key"/>
            ……
</application>

复制代码

! ! Remember to paste only from <meta_data, the front is to inform you of the location

and then configure the following permissions

复制代码

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

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

Why are there so many permissions?

Then in MainActivity:

复制代码

Finally, you need a layout display map

<com.amap.api.maps.MapView
        android:id="@+id/map_view"
        android:layout_width="match_parent"
        android:layout_height="match_parent" >
    </com.amap.api.maps.MapView>

Map is integrated!
