Android百度地图开发入门教程

1.平台注册登录
2.创建应用
3.Android studio配置
4.代码编写
5.最终效果(建议真机)

1.平台注册登录

登录百度地图开放平台网站注册并登录

网址:https://lbsyun.baidu.com

2.创建应用

点击右上角控制台，然后点击左侧“我的应用”，最后点击"创建应用"

应用名随便填,应用类型选Android SDK。找到Android目录下的debug.keystore文件，并复制其文件路径。(找不到在磁盘中全局搜索debug.keystore)

在java JDK中的bin目录打开命令窗口输入keytool -list -v -keystore +刚复制的debug.keystore文件路径

密钥库口令默认为 “android” (注:输入不显示),生成成功复制SHA1内容,发布版,开发版输入内容相同

使用AS创建android项目,复制主入口activity包名,点击提交生成应用。复制其中访问应用的AK

3.Android studio配置

打开AndroidMainifest.xml 配置meta-data标签，value值为刚复制的AK值

下载开发包

根据想要的功能下载开发包(选择JAR类型)

解压下好的压缩文件,进入libs文件夹，复制所有文件

将Android studio工程类型切换成project 把复制的文件粘贴到libs中

在build.gradle中配置如图内容,点击同步

android studio切换Android工程时出现了jniLibs文件夹即为加载成功

在AndroidManifest.xml中配置百度的服务

引入各种权限配置

<!--    网络定位--><uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"></uses-permission>
<!--    GPS定位--><uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"></uses-permission>
<!--    WIFI定位--><uses-permission android:name="android.permission.ACCESS_WIFI_STATE"></uses-permission>
<!--    运营商相关接口--><uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"></uses-permission>
<!--    获取wifi权限--><uses-permission android:name="android.permission.CHANGE_WIFI_STATE"></uses-permission>
<!--    写入离线定位数据--><uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"></uses-permission>
<!--    访问网络--><uses-permission android:name="android.permission.INTERNET"></uses-permission>
<!--    android9以上前台服务--><uses-permission android:name="android.permission.FOREGROUND_SERVICE"></uses-permission><uses-permission android:name="android.permission.READ_PHONE_STATE"></uses-permission>

4.代码编写

xml文件

<?xml version="1.0" encoding="utf-8"?>
