百度地图SDK使用[通俗易懂]

大家好，又见面了，我是你们的朋友全栈君。

将百度地图官网下载的SDK的压缩包解压得到如下文件：

百度地图SDK使用[通俗易懂]

将BaiduLBS_Android.jar复制到libs目录下，并点击同步

版本比较老的Gradle可能没有这一句，需要手动添加，然后同步

在main 目录下新建jniLibs文件夹，并将百度地图给的sdk里剩下的so文件导入

<!———————-开始代码部分—————————–>

AndroidManifest.xml中

添加权限如下：

    <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>
    <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>
    <uses-permission android:name="android.permission.ACCESS_WIFI_STATE"/>
    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>
    <uses-permission android:name="android.permission.CHANGE_WIFI_STATE"/>
    <uses-permission android:name="android.permission.READ_PHONE_STATE"/>
    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
    <uses-permission android:name="android.permission.INTERNET"/>
    <uses-permission android:name="android.permission.MOUNT_UNMOUNT_FILESYSTEMS"/>
    <uses-permission android:name="android.permission.WAKE_LOCK"/>

在<application>标签中声明

<!--百度地图秘钥-->
        <meta-data
            android:name="com.baidu.lbsapi.API_KEY"
            android:value="你在百度地图申请的秘钥"
            />

  <service android:name="com.baidu.location.f" android:enabled="true"
            android:process=":remote">
        </service>

activity_main.xml 布局文件代码：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="match_parent"
    android:layout_height="match_parent">
    <com.baidu.mapapi.map.MapView
        android:id="@+id/bmapView"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:clickable="true"/>
</LinearLayout>
