高德地图-搜索-路径规划

一、打开高德开放平台
二、建立应用

SHA1: F5:31:C2:B7:9F:A4:05:DF:5F:B2:F1:70:9B:03:B9:BB:50:CF:58:CB
三、添加新key:dd9dde5da25a5811031cb1beb5acb7a5
    sha1值获取：找到系统默认的debug.keystore(C:\Users\Administrator\.android\debug.keystore)
                在cmd窗口或android studio 中的Terminal中执行命令：keytool -v -list -keystore keystore地址
四、添加jar和so库(不要添加v4包)
    so库添加方式：
        第一种：使用默认配置，不须要修改build.gradle。在 main 目录下建立文件夹 jniLibs (若是有就不须要建立了)，将下载文件的 armeabi 文件夹复制到这个目录下,若是已经有这个目录，将下载的 so 库复制到这个目录便可。
        第二种：使用自定义配置，将下载文件的 armeabi 文件夹复制到 libs 目录，若是有这个目录,请将下载的 so 库复制到这个目录，

而后打开build.gradle，找到 android标签复制：

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

五、配置
    一、配置AndroidManifest.xml
        一、声明Service组件（不须要）
            <service android:name="com.amap.api.location.APSService"></service>
        二、声明权限

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.diyu">

    <application
        android:allowBackup="true"

        android:label="@string/app_name"

        android:supportsRtl="true"
        android:theme="@style/AppTheme">
        <activity android:name=".MainActivity">

                <category android:name="android.intent.category.LAUNCHER" />

        </activity>
