我已经在应用中实施了一些地理栅栏,并使用我的测试设备上的模拟位置(运行Android 5.0.1的三星S4)对它们进行了测试。在使用模拟位置时,转换检测一直在100%的时间内工作。我现在已经转移到其他Android设备上,并将应用程序放置在经常(实际)进入并离开地理围栏位置的某些电话上,并且我注意到检测到OFTEN不起作用。这真的很不方便,所以我希望能有一些方法使检测更加一致。要创建一致的Android地理栅栏监测
我的代码调用地理围栏:
private void startGeofenceMonitoring() {
Log.d(TAG, "startGeofenceMonitoring called");
try {
Geofence geofence = new Geofence.Builder()
.setRequestId(GEOFENCE_ID)
.setCircularRegion(51.364516, -0.189643, 150)
.setExpirationDuration(Geofence.NEVER_EXPIRE)
.setNotificationResponsiveness(1000)
.setTransitionTypes(Geofence.GEOFENCE_TRANSITION_ENTER | Geofence.GEOFENCE_TRANSITION_EXIT)
.build();
GeofencingRequest geofencingRequest = new GeofencingRequest.Builder()
.setInitialTrigger(GeofencingRequest.INITIAL_TRIGGER_ENTER | GeofencingRequest.INITIAL_TRIGGER_EXIT)
.addGeofence(geofence)
.build();
Intent intent = new Intent(this, GeofenceService.class);
PendingIntent pendingIntent = PendingIntent.getService(this, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT);
if (!googleApiClient.isConnected()) {
Log.d(TAG, "GoogleApiClient is not connected");
} else {
if (ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
ActivityCompat.requestPermissions(MapsActivity.this, new String[]{Manifest.permission.ACCESS_FINE_LOCATION}, LOCATION);
return;
}
LocationServices.GeofencingApi.addGeofences(googleApiClient, geofencingRequest, pendingIntent)
.setResultCallback(new ResultCallback<Status>() {
@Override
public void onResult(@NonNull Status status) {
if (status.isSuccess()) {
Log.d(TAG, "Successfully added Geofence");
} else {
Log.d(TAG, "Failed to add geofence - " + status.getStatus());
}
}
});
}
} catch (SecurityException e) {
Log.d(TAG, "SecurityException - " + e.getMessage());
}
}
GeofenceService.java:
public class GeofenceService extends IntentService {
public static final String TAG = "GeofenceService";
DatabaseReference mRootRef = FirebaseDatabase.getInstance().getReference();
public GeofenceService() {
super(TAG);
}
@Override
protected void onHandleIntent(Intent intent) {
GeofencingEvent event = GeofencingEvent.fromIntent(intent);
if (event.hasError()) {
//TODO:
} else {
double longitude = 0;
double latitude = 0;
int transition = event.getGeofenceTransition();
List<Geofence> geofences = event.getTriggeringGeofences();
Geofence geofence = geofences.get(0);
String requestID = geofence.getRequestId();
longitude = event.getTriggeringLocation().getLongitude();
latitude = event.getTriggeringLocation().getLatitude();
final FirebaseUser user = FirebaseAuth.getInstance().getCurrentUser();
if (longitude != 0 && latitude != 0) {
if (transition == Geofence.GEOFENCE_TRANSITION_ENTER) {
Log.d(TAG, "Entering geofence - " + requestID);
//My on enter code
} else if (transition == Geofence.GEOFENCE_TRANSITION_EXIT) {
Log.d(TAG, "Exited geofence - " + requestID);
//My on exit code
}
} else {
mRootRef.child("users/" + user.getUid() + "/error").setValue("lat/long = 0");
}
}
}
我看到网上说用说的广播接收机的工作比我更好过完成但令人尴尬的是,我不太了解如何将我所做的事转化为别人所建议的。
感谢。
