1. Download the SDK
download address of Baidu map : http://lbsyun.baidu.com/index.php?title=android-locsdk/geosdk-android-download
2. Apply for a key value to
register a Baidu account- > log in to Baidu map official website ——> Console —–> Create an application
The official website address of the specific method for obtaining the key (aka AK): http://lbsyun.baidu.com/apiconsole/key
3. Get the .jar file by decompressing it and put it in the libs file In (copy can also), manually add to the dependent library (right-click Add-)
4. Add the service in the AndroidManifest Application:
<meta-data
android:name="com.baidu.lbsapi.API_KEY"
android:value="AK" />//在百度官网自行申请
<service
android:name="com.baidu.location.f"
android:enabled="true"
android:process=":remote" />
5. Add permissions
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" /> <!-- provider的权限 -->
<uses-permission android:name="android.permission.ACCESS_GPS" /> <!-- 获取精确gps位置 -->
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" /> <!-- 获取粗略位置 -->
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" /> <!-- 允许程序访问额外的定位提供者指令获取模拟定位信息 -->
<uses-permission android:name="android.permission.ACCESS_LOCATION_EXTRA_COMMANDS" /> <!-- 网络链接 -->
<uses-permission android:name="android.permission.INTERNET" />

* setScanSpan < 1000 则为 app主动请求定位；
* setScanSpan >=1000,则为定时定位模式（setScanSpan的值就是定时定位的时间间隔））
* 定时定位模式中，定位sdk会按照app设定的时间定位进行位置更新，定时回调定位结果。此种定位模式适用于希望获得连续定位结果的情况。
* 对于单次定位类应用，或者偶尔需要一下位置信息的app，可采用app主动请求定位这种模式。*/

After entering the target address, you can choose to use Gaode map or Baidu map to open the navigation, which is convenient and practical
