 I am new in android.Now i am working on a project using android map.how can we get a android browser key from google api console.can you help me 
 

мне нужно знать, какой URL-адрес там указан.когда я захожу в консоль Google api, я вижу это fromat.example.com /. Один URL или шаблон на строку.здесь, в этом коде, как я могу создать browserkey.
этот проект показывает наши ближайшие места на googlemap. но когда я запускаю этот проект, используя ключ api Android, я могу получить карту, но не получить аккуратные места. я думаю, что этому коду нужен ключ браузера для отображения ближайших мест.

 **Here is my code**        
public class MainActivity extends FragmentActivity implements LocationListener{

    GoogleMap mGoogleMap;   
    Spinner mSprPlaceType;  

    String[] mPlaceType=null;
    String[] mPlaceTypeName=null;

    double mLatitude=0;
    double mLongitude=0;


    @Override
    protected void onCreate(Bundle savedInstanceState) {


        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);     

        // Array of place types
        mPlaceType = getResources().getStringArray(R.array.place_type);

        // Array of place type names
        mPlaceTypeName = getResources().getStringArray(R.array.place_type_name);

        // Creating an array adapter with an array of Place types
        // to populate the spinner
        ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, android.R.layout.simple_spinner_dropdown_item, mPlaceTypeName);

        // Getting reference to the Spinner 
        mSprPlaceType = (Spinner) findViewById(R.id.spr_place_type);

        // Setting adapter on Spinner to set place types
        mSprPlaceType.setAdapter(adapter);

        Button btnFind;

        // Getting reference to Find Button
        btnFind = ( Button ) findViewById(R.id.btn_find);


        // Getting Google Play availability status
        int status = GooglePlayServicesUtil.isGooglePlayServicesAvailable(getBaseContext());


        if(status!=ConnectionResult.SUCCESS){ // Google Play Services are not available

            int requestCode = 10;
            Dialog dialog = GooglePlayServicesUtil.getErrorDialog(status, this, requestCode);
            dialog.show();

        }else { // Google Play Services are available

            // Getting reference to the SupportMapFragment
            SupportMapFragment fragment = ( SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map);

            // Getting Google Map
            mGoogleMap = fragment.getMap();

            // Enabling MyLocation in Google Map
            mGoogleMap.setMyLocationEnabled(true);



            // Getting LocationManager object from System Service LOCATION_SERVICE
            LocationManager locationManager = (LocationManager) getSystemService(LOCATION_SERVICE);

            // Creating a criteria object to retrieve provider
            Criteria criteria = new Criteria();

            // Getting the name of the best provider
            String provider = locationManager.getBestProvider(criteria, true);

            // Getting Current Location From GPS
            Location location = locationManager.getLastKnownLocation(provider);

            if(location!=null){
                    onLocationChanged(location);
            }

            locationManager.requestLocationUpdates(provider, 20000, 0, this);

            // Setting click event lister for the find button
            btnFind.setOnClickListener(new OnClickListener() {

                    int selectedPosition = mSprPlaceType.getSelectedItemPosition();
