Android 百度定位SDKv4.2及6.0_百度定位實例_安卓定位實例

介紹

由於項目需要、前幾天一直在研究百度定位的功能、通過不斷的實踐終於有結果了、不願意獨享

現在我把我的研究成果和大家分享一下、其實百度的 API 已經相當不錯了

這之所以要寫出來、一是自己做一個筆記、二是以方便一起朋友少走彎路

導入庫文件

在相關下載最新的庫文件、將liblocSDK4d.so文件拷貝到libs/armeabi目錄下

將locSDK4.2.jar文件拷貝到工程的libs目錄下、並在工程屬性->Java Build Path->Libraries中選擇“Add JARs”

選定locSDK4.2.jar、確定後返回、這樣您就可以在程序中使用百度定位SDK了

設置AndroidManifest.xml
在application標籤中聲明service組件、每個app擁有自己單獨的定位service

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

聲明使用權限

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

使用基本定位功能
基本定位功能指的根據用戶實際需求、返回用戶當前位置的基礎定位服務

包含GPS和網絡定位（Wi-Fi和基站定位）功能、基本定位功能同時還支持結合定位結果的反地理編碼功能

離線定位、位置提醒功能和地理圍欄功能

到這裏一個簡單的百度定位demo就可以實現了、那麼需要注意的是一定要在 libs 下面引入 armeabi/liblocSDK4d.so

若資源對你有幫助、掃描下方的二維碼、關注DD博客微信公衆號（ddblogs）吧

最後給貼上Demo的源代碼、希望對大家有用、有興趣的哥們可以下載看看
