Get real-time location through Baidu positioning SDK

There was an article about positioning the base station. At that time, the testing environment was Xiaomi + Mobile, which was relatively smooth.

But in practice, there is a problem-the numbers of China Unicom and China Telecom cannot be located!

The best solution is to use a third-party SDK to locate the problem.

Baidu's positioning SDK is still very good. It can be located through WiFi, GPS, GPRS, and has nothing to do with the operator.

Final effect:

The page contains a button and textview. click the button to start positioning. The result is displayed in textview.

Steps:

Add SDK

Go here to download the latest SDK, which is now 3.3.

Copy the liblocsdk3.so file to the libs/armeabi directory. Copy the locsdk3.3.jar file to the libs directory of the project, select "add jars" from Project Properties> JAVA build path> libraries, select locsdk3.3.jar, and return after confirmation. In this way, you can use Baidu positioning SDK in the program.

Add Service

Add the following in the manifest file:

<service android:name="com.baidu.location.f" android:enabled="true"android:process=":remote" android:permission="android.permission.BAIDU_LOCATION_SERVICE">    <intent-filter>          <action android:name="com.baidu.location.service_v3.3"></action>    </intent-filter></service>

Declare Permissions

<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>
