我正在尝试创建一个服务，插入设备在数据库中的位置，当设备位于地理围栏列表之外时，它会向服务器发送另一条消息。现在我只有服务将位置发送到服务器的部分。
以下是我所拥有的：
public class UbicacionEmisor extends Service {
private static final String TAG = "BOOMBOOMTESTGPS";
private LocationManager mLocationManager = null;
private static final int LOCATION_INTERVAL = 10000;
private static final float LOCATION_DISTANCE = 0;
private SOService mService;
SharedPreferences preferences;
SharedPreferences.Editor editor;
private static final String PREF_NAME = "decaught-preferences";
private List<GeofenceR> geofenceRList = new ArrayList<>();
private class LocationListener implements android.location.LocationListener {
Location mLastLocation;
public LocationListener(String provider) {
Log.e(TAG, "LocationListener " + provider);
mLastLocation = new Location(provider);
}
@Override
public void onLocationChanged(Location location) {
Log.e(TAG, "onLocationChanged: " + location);
mLastLocation.set(location);
SimpleDateFormat f = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ssZ");
String date = f.format(new Date());
editor.putString("latitude", String.valueOf(location.getLatitude()));
editor.putString("longitude", String.valueOf(location.getLongitude()));
editor.apply();
//This part is used to send to the server the Location
mService.add_location("Token " + preferences.getString("token", ""), preferences.getString("imei",""), date, String.valueOf(location.getLatitude()), String.valueOf(location.getLongitude()), true).enqueue(new Callback<escoladeltreball.org.decaught.models.Location>() {
@Override
public void onResponse(Call<escoladeltreball.org.decaught.models.Location> call, Response<escoladeltreball.org.decaught.models.Location> response) {
if (response.isSuccessful()) {
Log.d("UbicationEmisor", "Ubication send");
} else {
int statusCode = response.code();
if (response.code() == 400) {
try {
Log.v("Error code 400", response.errorBody().string());
} catch (IOException e) {
e.printStackTrace();
}
}
Log.d("UbicationEmisor", "Ubication not send, error: " + statusCode);
Log.d("UbicationEmisor", "Ubication not send, error: " + response.errorBody());
// handle request errors depending on status code
}
}
@Override
public void onFailure(Call<escoladeltreball.org.decaught.models.Location> call, Throwable t) {
Log.d("RolSelectionActivity", "Error trying to connect to database");
}
});
}
@Override

return null;
}
@Override
public int onStartCommand(Intent intent, int flags, int startId) {
Log.e(TAG, "onStartCommand");
super.onStartCommand(intent, flags, startId);
preferences = getSharedPreferences(PREF_NAME, Context.MODE_PRIVATE);
editor = preferences.edit();
return START_STICKY;
}
@Override
public void onCreate() {
Log.e(TAG, "onCreate");
mService = ApiUtils.getSOService();
obtainGeofences();
initializeLocationManager();
try {
mLocationManager.requestLocationUpdates(
LocationManager.NETWORK_PROVIDER, LOCATION_INTERVAL, LOCATION_DISTANCE,
mLocationListeners[1]);
} catch (java.lang.SecurityException ex) {
Log.i(TAG, "fail to request location update, ignore", ex);
} catch (IllegalArgumentException ex) {
Log.d(TAG, "network provider does not exist, " + ex.getMessage());
}
try {
mLocationManager.requestLocationUpdates(
LocationManager.GPS_PROVIDER, LOCATION_INTERVAL, LOCATION_DISTANCE,
mLocationListeners[0]);
} catch (java.lang.SecurityException ex) {
Log.i(TAG, "fail to request location update, ignore", ex);

Log.d(TAG, "gps provider does not exist " + ex.getMessage());
}
}
private void obtainGeofences() {
String imei = preferences.getString("imei","");
mService.listGeofence("Token " + preferences.getString("token", ""), imei).enqueue(new Callback<List<GeofenceR>>() {

你知道怎么做地理围栏吗？还是我应该重新开始？
最佳答案
我和GeoFences合作过，我真的建议你读这个Geofence Documentation和这个example
关于您的问题，我建议您重新开始，因为GeoFences不使用LocationManager（或者至少不显式地）。
您要执行以下操作（步骤列表）：
定义地理信息LNG/LAT和RADIUS并指定退出事件
mGeofenceList.add(new Geofence.Builder()
// Set the request ID of the geofence. This is a string to identify this
// geofence.
.setRequestId(entry.getKey())
.setCircularRegion(
entry.getValue().latitude,
entry.getValue().longitude,
Constants.GEOFENCE_RADIUS_IN_METERS
)
.setExpirationDuration(Constants.GEOFENCE_EXPIRATION_IN_MILLISECONDS)
.setTransitionTypes(Geofence.GEOFENCE_TRANSITION_EXIT)
.build());
定义挂起意图
public class MainActivity extends AppCompatActivity {
// ...
private PendingIntent getGeofencePendingIntent() {
// Reuse the PendingIntent if we already have it.
if (mGeofencePendingIntent != null) {
return mGeofencePendingIntent;
}
Intent intent = new Intent(this, GeofenceTransitionsIntentService.class);
// We use FLAG_UPDATE_CURRENT so that we get the same pending intent back when
// calling addGeofences() and removeGeofences().
mGeofencePendingIntent = PendingIntent.getService(this, 0, intent, PendingIntent.
FLAG_UPDATE_CURRENT);
return mGeofencePendingIntent;
}
**Define the Service**
public class GeofenceTransitionsIntentService extends IntentService {
// ...
protected void onHandleIntent(Intent intent) {
GeofencingEvent geofencingEvent = GeofencingEvent.fromIntent(intent);
if (geofencingEvent.hasError()) {
String errorMessage = GeofenceErrorMessages.getErrorString(this,
geofencingEvent.getErrorCode());
Log.e(TAG, errorMessage);
return;
}
// Get the transition type.
int geofenceTransition = geofencingEvent.getGeofenceTransition();
// Test that the reported transition was of interest.
if (geofenceTransition == Geofence.GEOFENCE_TRANSITION_EXIT) {
// Get the geofences that were triggered. A single event can trigger
// multiple geofences.
// HERE YOUR CODE TO SAVE THE LOCATION IN THE DB
// AND SEND THE NOTIFICATION
sendNotification(geofenceTransitionDetails);
Log.i(TAG, geofenceTransitionDetails);
} else {
// Log the error.
Log.e(TAG, getString(R.string.geofence_transition_invalid_type,
geofenceTransition));
}
}
NB公司
使用地理围栏最烦人的事情就是打瞌睡。
过了一段时间，你将看不到任何通知，因为打瞌睡是为了节省电池，所以要记住这一点。
