Android高德地圖之路徑規划

首先在

                       

                  注冊一個appke 

　　　　

　　　　在AndroidManifest里面加上權限：

　　　　　　　　

<!--允許程序打開網絡套接字-->
<uses-permission android:name="android.permission.INTERNET" />
<!--允許程序設置內置sd卡的寫權限-->
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<!--允許程序獲取網絡狀態-->
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<!--允許程序訪問WiFi網絡信息-->
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
<!--允許程序讀寫手機狀態和身份-->
<uses-permission android:name="android.permission.READ_PHONE_STATE" />
<!--允許程序訪問CellID或WiFi熱點來獲取粗略的位置-->
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />


在<application

</application>
里面加上

<meta-data
    android:name="com.amap.api.v2.apikey"
    android:value="key">
    //開發者申請的key
</meta-data>

例如：<application

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

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
    <meta-data
        android:name="com.amap.api.v2.apikey"
        android:value="key">
        //開發者申請的key
    </meta-data>
</application>


在app的 build.gradle 里面添加依賴:
　　　　　　　　

compile 'com.amap.api:3dmap:latest.integration'//高德地圖——3D地圖so及包
compile 'com.amap.api:location:latest.integration'  // 高德地圖 定位功能
compile 'com.amap.api:search:latest.integration' //高德地圖  搜索功能

在java源代碼里面添加兩個包

　　

在drawable中mipmap-xxhdpi和添加路徑規划所需要的圖片
