Baidu Map API get latitude and longitude and city name

to integrate Baidu API positioning needs to complete the following steps:1: Registered developer
2: Apply for key
3: Download the jar package
4: Code Integrationfirst Look at the effect:

1: Registered developerIt is best to apply in advance, 1, 2 days for audit
2: Apply for keyI use Android Studio, so use the command line to view the SHA1 code
3: Download the jar packagesimply download the "Location feature" development package to
4: Code Integration (detailed official explanation, the following code is concise and practical mainly)

Package Com.union.roid.testroid;import Android.app.activity;import Android.os.bundle;import android.util.Log; Import Com.baidu.location.bdlocation;import Com.baidu.location.bdlocationlistener;import Com.baidu.location.locationclient;import Com.baidu.location.locationclientoption;public class MainActivity extends    Activity {public locationclient mlocationclient = null;    Public Bdlocationlistener MyListener = new Mylocationlistener ();        @Override protected void OnCreate (Bundle savedinstancestate) {super.oncreate (savedinstancestate);        Setcontentview (R.layout.activity_main); Mlocationclient = new Locationclient (Getapplicationcontext ());//Declaration Locationclient Class Mlocationclient.registerlocation Listener (MyListener);//Register the Listener function locationclientoption option = new Locationclientoption ();//Set Request parameters Option.setlo Cationmode (LocationClientOption.LocationMode.Hight_Accuracy);//Set positioning mode Option.setcoortype ("Bd09ll");// The returned positioning result is Baidu latitude and longitude, the default value gcj02 OPTION.SETSCAnspan (5000);//sets the time interval for initiating a location request to 5000ms option.setisneedaddress (true);//The Returned location result contains address information option.setneeddevicedirect        (true);//The positioning result returned contains the direction of the phone head mlocationclient.setlocoption (option); Mlocationclient.start ();//Start request if (mlocationclient! = null && mlocationclient.isstarted ()) Mloca        Tionclient.requestlocation ();    else LOG.D ("location", "locclient was null or not started"); } public class Mylocationlistener implements Bdlocationlistener {@Override public void onreceivelocation (bdlocation location)            {if (location = = null) return;            StringBuffer sb = new StringBuffer (256);            Sb.append ("Time:");            Sb.append (Location.gettime ());            Sb.append ("\nerror Code:");            Sb.append (Location.getloctype ());            Sb.append ("\nlatitude:");            Sb.append (Location.getlatitude ());            Sb.append ("\nlontitude:"); Sb.append (LocatiOn.getlongitude ());            Sb.append ("\nradius:");            Sb.append (Location.getradius ());                if (location.getloctype () = = bdlocation.typegpslocation) {sb.append ("\nspeed:");                Sb.append (Location.getspeed ());                Sb.append ("\nsatellite:");            Sb.append (Location.getsatellitenumber ());                } else if (location.getloctype () = = bdlocation.typenetworklocation) {sb.append ("\naddr:");            Sb.append (Location.getaddrstr ());            } LOG.V ("--->", "=========");        LOG.V ("--->", sb.tostring ()); }    }}
