问题 I use LocationManager.requestLocationUpdates to request location for both GPS and network provider, and the location settings is selected in "Location and security" settings. But onLocationChanged is never called in 30 seconds. However, the code works well on other cellphone such as HTC desire. But i found there is other app such as Renren can get location in Samsung Galaxy S2. Could you anyone help to solve the problem? 回答1: You must be from china. And your galaxy S2 is sold only in china!

问题 I'm trying to limit my program to take location updates every 10 seconds instead of constant updates in order to reduce battery drain. This works fine when i'm debugging indoors and the signal is weak (i.e. the GPS icon flashes), but if the phone gets a proper fix (i.e. the GPS icon is static) the update interval increases to roughly a second. I know that the code mLocationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, updateInterval*1000, 0, this); will not force the GPS to

问题 I think I’m doing this right? I have this code which starts looking for my GPS location via a MyLocationListener method not displayed here, that works but I want to stop the locationManager onPause, I think or whenever this activity is not current, but I can’t get the removeUpdates code to resolve. locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE); locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, MINIMUM_TIME_BETWEEN_UPDATES, MINIMUM_DISTANCE

问题 I would like to use Android's Proximity Alert for my garage door app. I have a button setup, that when pressed add's the proximity alert and starts tracking location. I want it to track indefinitely until I either enter or exit the proximity. If entering it will open the garage door, if exiting it will close the garage door after which I remove the proximity alert and GPS shuts off. I have it working close to perfectly. The problem is, when I press the button while in my driveway, hence in

问题 So I've spent the past few weeks working on my Android App and looking into the best way of implementing what I need to do, but still can't quite get it right.. Any/all help is greatly appreciated, as I am still getting the hang of things.. Task: (Assuming the "Location"/GPS Setting is currently off), I need to have my App constantly be listening for the "Location" Setting to be turned ON.. At this point, simply start an Activity. Ideas: These are all the different ways I think it could

问题 I'm working with passive provider, with this code. Intent intent = new Intent(PASSIVE_ACTION); PendingIntent pi = PendingIntent.getBroadcast(this, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT); mLocationManager = (LocationManager) getSystemService(LOCATION_SERVICE); mLocationManager.requestLocationUpdates(LocationManager.PASSIVE_PROVIDER, 0, 0, pi); and I define broadcast receiver in AndroidManifest.xml <receiver android:name="passiveLocationReceiver" android:enabled="true" > <intent-filter>

问题 I am trying to write a location tracking service that starts as soon as the app is started, stops as soon as the app goes into the background, and restarts as soon as the app comes back to the foreground. The service should poll for a new location every 5 minutes while it is running (to conserve battery) and when a new location is found (onLocationChanged()) it updates a variable that I can retrieve from any Activity. I have tried binding a service in my custom Application class but the
