百度地图SDK |
[TOC]
- 打开**百度开发者平台 **: http://lbsyun.baidu.com/index.php?title=androidsdk
- 获取SHA1
- 发布版SHA1和开发版SHA1是可以一样的,这里我就都用开发版的SHA1了
- 点击提交就可以获取当前应用的app Key了
- 下载完后可以看到有以下文件
- 全部放置到项目的libs目录下, 并给jar包添加依赖
- 先在AndroidMainfest.xml中的application节点中配置信息：
<application
......>
<meta-data
android:name="com.baidu.lbsapi.API_KEY" <!--这里不需要修改-->
android:value="开发者key" /> <!--这里需要我们之前申请的app Key-->
......
</application>- 在AndroidMainfest.xml中添加以下权限
<uses-permission android:name="com.android.launcher.permission.READ_SETTINGS" />
<!-- 这个权限用于进行网络定位 -->
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<!-- 这个权限用于访问GPS定位 -->
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<!-- 用于访问wifi网络信息，wifi信息会用于进行网络定位 -->
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
<!-- 获取运营商信息，用于支持提供运营商信息相关的接口 -->
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<!-- 用于读取手机当前的状态 -->
<uses-permission android:name="android.permission.READ_PHONE_STATE" />
<!-- 写入扩展存储，向扩展卡写入数据，用于写入离线定位数据 -->
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<!-- 访问网络，网络定位需要上网 -->
<uses-permission android:name="android.permission.INTERNET" />- 在build.gradle文件中的android代码块中添加以下代码
sourceSets {
main {
jniLibs.srcDirs = ['libs']
}
}
- 使用定位功能需要在AndroidManifest.xml中做以下配置
<service
android:name="com.baidu.location.f"
android:enabled="true"
android:process=":remote">
</service>- 布局代码
