Android uses Baidu AK positioning to obtain detailed location information complete example steps

1. Import related dependent libraries:

implementation 'com.baidu.android:liblocation:7.3.2'

 2. Create  LocationClient an instance:

LocationClient mLocationClient = new LocationClient(context);

3, set  LocationClientOption:

LocationClientOption option = new LocationClientOption();
option.setIsNeedAddress(true);// 获取详细的地址信息
option.setOpenGps(true);// 打开 GPS
option.setCoorType("bd09ll");// 设置坐标类型
option.setScanSpan(10000);// 定位间隔时间（单位：毫秒）
mLocationClient.setLocOption(option);

 4, Created  BDAbstractLocationListener subclasses:

public class MyLocationListener extends BDAbstractLocationListener {
    @Override
    public void onReceiveLocation(BDLocation location) {
        // 获取详细的地址信息
        String province = location.getProvince(); // 获取省份
        String city = location.getCity(); // 获取城市
        String district = location.getDistrict(); // 获取区县
        String street = location.getStreet(); // 获取街道信息
        String address = location.getAddrStr(); // 获取详细地址信息
        Log.d("location", "province: " + province + ", city: " + city + ", district: " + district + ", street: " + street + ", address: " + address);
    }
}

 5. Registered  BDAbstractLocationListener subclasses:

MyLocationListener myLocationListener = new MyLocationListener();
mLocationClient.registerLocationListener(myLocationListener);

6. Start positioning:

mLocationClient.start();

7. You need to add the following permissions in AndroidManifest.xml: (6.0 and above may also apply for dynamic permissions)

<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-permission android:name="android.permission.READ_PHONE_STATE" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

 At the same time, you also need to register the application on the Baidu developer platform and obtain the AK (Access Key), and set the AK in the code: (same as step 3) 

LocationClientOption option = new LocationClientOption();
option.setIsNeedAddress(true);
option.setOpenGps(true);
option.setCoorType("bd09ll");
option.setScanSpan(10000);
option.setIgnoreKillProcess(false);
option.setEnableSimulateGps(false);
option.setEnableCache(true);
option.setWifiCacheTimeOut(5 * 60 * 1000);
option.setAk("Your AK");
mLocationClient.setLocOption(option);
