thumar / geofencing Goto Github PK

I write applications in which geofences on the map will be displayed. For now, I managed to create one geofences which is displayed on the map. My question is how to convert the code so that you can display more than one geofences? I'm new to this topic, could someone help me, explain how to do it? Below I put two classes that I use.

MainActivity:

package com.app.androidkt.geofencing;
import android.Manifest;
import android.app.PendingIntent;
import android.content.pm.PackageManager;
import android.graphics.Color;
import android.os.Bundle;
import android.support.annotation.NonNull;
import android.support.annotation.Nullable;
import android.support.v4.app.ActivityCompat;
import android.support.v7.app.AppCompatActivity;
import android.util.Log;
import com.google.android.gms.common.ConnectionResult;
import com.google.android.gms.common.GoogleApiAvailability;
import com.google.android.gms.common.api.GoogleApiClient;
import com.google.android.gms.location.Geofence;
import com.google.android.gms.location.GeofencingRequest;
import com.google.android.gms.location.LocationServices;
import com.google.android.gms.maps.CameraUpdateFactory;
import com.google.android.gms.maps.GoogleMap;
import com.google.android.gms.maps.OnMapReadyCallback;
import com.google.android.gms.maps.SupportMapFragment;
import com.google.android.gms.maps.model.Circle;
import com.google.android.gms.maps.model.CircleOptions;
import com.google.android.gms.maps.model.LatLng;
import com.google.android.gms.maps.model.Marker;
import com.google.android.gms.maps.model.MarkerOptions;
import java.util.ArrayList;
import java.util.Map;
public class MainActivity extends AppCompatActivity implements OnMapReadyCallback, GoogleApiClient.ConnectionCallbacks, GoogleApiClient.OnConnectionFailedListener {
private static final String TAG = "MainActivity";
private static final int REQUEST_LOCATION_PERMISSION_CODE = 101;
private GoogleMap googleMap;
protected ArrayList mGeofenceList;
private GeofencingRequest geofencingRequest;
private GoogleApiClient googleApiClient;
private boolean isMonitoring = false;
private MarkerOptions markerOptions;
private Marker currentLocationMarker;
private PendingIntent pendingIntent;
@OverRide
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
SupportMapFragment mapFragment = (SupportMapFragment) getSupportFragmentManager()
.findFragmentById(R.id.map);
mapFragment.getMapAsync(this);
mGeofenceList = new ArrayList();
getGeofence();
googleApiClient = new GoogleApiClient.Builder(this)
.addApi(LocationServices.API)
.addConnectionCallbacks(this)
.addOnConnectionFailedListener(this).build();
if (ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION)
!= PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.ACCESS_FINE_LOCATION, Manifest.permission.ACCESS_COARSE_LOCATION}, REQUEST_LOCATION_PERMISSION_CODE);
}
}
@nonnull
private void getGeofence() {
for (Map.Entry<String, LatLng> entry : Constants.AREA_LANDMARKS.entrySet()) {
mGeofenceList.add(new Geofence.Builder()
.setRequestId(entry.getKey())
.setCircularRegion(
entry.getValue().latitude,
entry.getValue().longitude,
Constants.GEOFENCE_RADIUS_IN_METERS
)
.setExpirationDuration(Geofence.NEVER_EXPIRE)
.setTransitionTypes(Geofence.GEOFENCE_TRANSITION_ENTER | Geofence.GEOFENCE_TRANSITION_EXIT)
.build());
}}
@OverRide
protected void onResume() {
super.onResume();
int response = GoogleApiAvailability.getInstance().isGooglePlayServicesAvailable(MainActivity.this);
if (response != ConnectionResult.SUCCESS) {
Log.d(TAG, "Google Play Service Not Available");
GoogleApiAvailability.getInstance().getErrorDialog(MainActivity.this, response, 1).show();
} else {
Log.d(TAG, "Google play service available");
}
}
@OverRide
protected void onStart() {
super.onStart();
}
@OverRide
protected void onStop() {
super.onStop();
}
@OverRide
protected void onDestroy() {
super.onDestroy();
}
@OverRide
public void onMapReady(GoogleMap googleMap) {
if (ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
return;
}
this.googleMap = googleMap;
LatLng latLng = Constants.AREA_LANDMARKS.get(Constants.GEOFENCE_ID_STAN_UNI2);
googleMap.moveCamera(CameraUpdateFactory.newLatLngZoom(latLng, 17f));
googleMap.setMyLocationEnabled(true);
Circle circle = googleMap.addCircle(new CircleOptions()
.center(new LatLng(latLng.latitude, latLng.longitude))
.radius(Constants.GEOFENCE_RADIUS_IN_METERS)
.strokeColor(Color.RED)
.strokeWidth(4f));
}
@OverRide
public void onConnected(@nullable Bundle bundle) {
Log.d(TAG, "Google Api Client Connected");
}
@OverRide
public void onConnectionSuspended(int i) {
Log.d(TAG, "Google Connection Suspended");
}
@OverRide
public void onConnectionFailed(@nonnull ConnectionResult connectionResult) {
Log.e(TAG, "Connection Failed:" + connectionResult.getErrorMessage());
}
}

The second class is Constants, in which I store the latitude and longitude of geofences.

package com.app.androidkt.geofencing;
import com.google.android.gms.maps.model.LatLng;
import java.util.HashMap;
public class Constants {
public static final String GEOFENCE_ID_STAN_UNI = "STAN_UNI";
public static final float GEOFENCE_RADIUS_IN_METERS = 100;
public static final HashMap<String, LatLng> AREA_LANDMARKS = new HashMap<String, LatLng>();
static {
// San Francisco International Airport.
AREA_LANDMARKS.put(GEOFENCE_ID_STAN_UNI, new LatLng(37.783888,-122.4009012));
// Googleplex.
AREA_LANDMARKS.put(GEOFENCE_ID_STAN_UNI2, new LatLng(51.250689, 22.572479));
// Test
AREA_LANDMARKS.put(GEOFENCE_ID_STAN_UNI, new LatLng(37.621313,-122.378955));
}
}
