you can subscribe to requestLocationUpdates via two ways one by specifing a PendingIntent the other is by using a LocationListener. When is advised the one and when the other?

In requestLocationUpdates(LocationManager.GPS_PROVIDER, 0, 0, this); if I put time interval and distance as zero, will this work, or shall I need to give a value greater than zero.
View 4 Replies View RelatedWhen i use LocationManager.requestLocationUpdates API and send geo fix form the shell (the one you obtain using telnet localhost 5554), device emulator receives location updates only two times and then get stalled. Have anyone faced and solved this issue?Also i can't send updates from DDMS perspective in eclipse. When i send manual location updates using Emulator control view nothing happens in emulator. In devices view running emulator is shown as online and i can see logs from it in LogCat view.
View 3 Replies View Relatedin order to save some battery, I was wondering what happens if an activity registers a requestLocationUpdates and then the user (or the os) puts it in background or kills it. Will the location manger still be active and then will the pending intent still be fired? In other words, will the location manager still be alive even if its lancher does not exist anymore? I'd really love this scenario because allows me to link an intent service that handles the location updates without bothering of have something always running waiting for good news from location.
View 9 Replies View RelatedI set locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 60000, 0f, this);
It has an odd behavior, locationChanged gets called every second instead of any time close to 1 minute. Secondly, locationChanged gets called every second for like 10 seconds, then stops completely, the gps satalites icon disappears, then only resumes again when the screen returns from display timeout.
what's wrong? I'm currently on android 1.5.
I tried using both getLastKnownLocation and requestLocationUpdates to get GPS coordinates from emulator.

I am wondering how you would cancel a notification when you are not the party executing the associated Intent.For example, think about an Intent like ACTION_VIEW and a data/url like http://google.com. This intent is then wrapped into a PendingNotification and used by a notification. So when the user clicks on the notification the intent is fired, the browser opens, but the notification is not cancelled. As my code is not the receiver of the Intent how should I cancel it?
View 3 Replies View RelatedI used AlarmManager to set the pending intent.
I need to find out the state of the pending intent, in other word, is this pending intent working or not. Boz i may need to cancel this pending intent, but before canceling it i want to make sure it's active.
But i see no function in AlarmManager can read this status.
Is is possible to get back a result intent when launching an Intent from a Notification? Similar to the way startActivityForResult() works ?
View 3 Replies View RelatedI set an PendingIntent on a Notification (notification.setLatestEventInfo). this intent is actually the same intent used to launch my app, only with a flag that I put in the extra (intent.putExtra(TAB_INDEX_PARAM_NAME, UPDATES_TAB_INDEX)).
So my first activity launches, it queries it's intent's extras and immediately navigates to an Alerts activity rather the normal activity on a regular launch.
The problem: from this point, every activation of my app navigates to this Alerts activity. when debugged, I find that the flag is "stuck" in the intent even though I removed/changed it. it just won't change.
How can change an extra on a giving Intent?
My app consists of an Activity and a service that runs in the background. The service periodically checks a website for an alarm condition. When the service detects the alarm, it should put a user notification into the status bar. If the user clicks the notification, it should display the app's activity. If the activity is already running, that activity should become visible. If the activity is not currently running, it should be created.
However the notification created by my service *always* creates a new instance of the activity, whether the activity is currently running or not. How do I get the desirable behavior?
Here is my service pseudo-code:
CODE:...............
I'm trying to develop a small app, that can retrieve GPS coordinates, and store them, so I can retrace the path I took. The thing is, the GPS on Android emulator is kind of screwing around with my nerves... First of all, the Mock Position system doesn't work, so I'm manually fixing the coordinates with telnet "geo fix" command. Second of all, the location listener seems to not be refreshing. I'm lauching the app, fixing a first set of coordinates, and observing the response I expect. But when I push a second set of coordinates, the app simply doesn't react.
I tried a lot -big lot- of ideas on this, and I'm kind of running short...
By the way, I'm developping on Eclipse with ADT, and the SDK for Android 1.5 (French HTC Heros are still with Android 1.5) so that I can use my own app.
Here's my code (just the coordinate retrieval part) :
CODE:.................
The application under development was to distinguish between the current location of the android phone based upon GPS signal when it was available. When it is not available, alternate methods are being used to distinguish the user's location. The application uses a private locationlistener class that implements the LocationListener class. The code within the onLocationChanged( ) method to be overridden will draw the location on the google map as a dot as they are received.
I have noticed however that something is amiss. If you start outside the building, it will estimate your position with several dots around your current location. When you walk through a building where you don't get GPS, the dots are not drawn as expected, but as soon as you step outside again on the other side of the building it rapidly draws dots far away from (but leading up to) your location, until it gets to your actual current location. I don't understand how these other values are retrieved and why they seem to poke their ugly heads in, once the user steps back outside............
I am having issues regarding a LocationListener in my Service called myService.
Here is my code:
///onStart method ..
onStart() {
locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE)
.
.
provider = locationManager.getBestProvider(criteria, true);
locationListener = (LocationListener) new MyLocationListener();
locationManager.requestLocationUpdates(provider, 0, 0, locationListener);
}
In my Activity there is a button which should stop the service. On the click of the button I am doing:
stopService(new Intent(getApplicationContext(), myService.class).................
I'm creating a notification with something similar to the following:
CODE:............
The key here is the extra data on the Intent for the notification. Once I click on the notification and it brings up SomeActivity, it brings up the activity and the extra data is available.
However, if I exit the app, hold the home button until the recent activities list comes up, and choose to open the app again, the extra data is still passed. Is there a way I can make this data get passed only if the app is opened via the Notification, and not from the recent activities list?
Can anyone post some sample code or point me to a tutorial on usage of GPS proximity alerts with PendingIntent?
View 2 Replies View RelatedI have a Service that uses the LocationListener, and it will be running from boot, indefinitely. My question is, how often is too often to listen for location updates? Is 5 minutes a battery killer? What about 1?
View 1 Replies View RelatedI've created service which has LocationListener in it. In order to keep service running the service is set as foreground.

View 2 Replies View RelatedI have an android application. Based on the current geo location of user, I want to fetch some remote data in background and store it. My implementation is: At specific interval a alarm fires up my service. Service uses an anonymous class to query current location and registers a locationListener callback. On call of onLocationChanged() I initiate the remote data fetch from server.
However once my service is done registering the location listener using anonymos class, it returns as expected; as it doesn't wait for callback to happen before finishing. Since callback takes some time and makes a call when service has already returned, it throws an error saying: java.lang.RuntimeException: Handler{43e82510} sending message to a Handler on a dead thread
Which is quite understandable. One quick workaround for me now is that I can use getLastKnownLocation from locationManager as that doesn't respond back by callback; but what if I do want the latest location right now, in a service and not activity? How can I wait for callback to happen and stop my service from returning.
Also, at what point does lastKnownlocation gets updated? Everytime GPS registers a new location; does it update it? What I want to know is that if it's not latest can it still be closed to latest? As I didn't see an option in android emulator to configure the time period between subsequent updates.
I am struggling a bit with the LocationListener in Android.I want to make an app that will get the current GPS location, and then afterwards sleep for a long time. A day or more. In this period of time i want the GPS notification icon to not show.What i have now, is in the onLocationChanged a Thread.sleep(x) but this will keep the icon on in the sleep period. How can i do this, and is there a better approach than to use Thread.sleep?
View 1 Replies View RelatedI am working on an Location Based Application. In this application i am using LocationListener class to update the location when the Location is changed.In each Activity i have different LocationListener to update location and do some specific work on updated location. But my problem is that when i am changing my location through DDMS , the LocationListener is being called of that current Activity as well as all the activities of the whole application where LocationListener has been defined. I don't know whether there should be one LocationListener for the whole application or for each Activity we should have different LocationListener.

View 5 Replies View RelatedI am adding some basic alarm functionality to my program via the use of AlarmManager and a BroadcastReceiver class (named AReceiver.java). My problem is that the data I add to the bundle attached to the Intent creating the PendingIntent appears to be lost. The only bundle data I can access in the AReceiver class is a android.intent.extra.ALARM_COUNT=1. Here is the basic code in the main activity class creating the Intent, PendingIntent and the AlarmManager: [Code in main activity - Notepadv3]
Intent intent = new Intent(Notepadv3.this, AReceiver.class);
intent.putExtra("teststring","hello, passed string in Extra");
PendingIntent alarmIntent = PendingIntent.getBroadcast(this, pendingPeriodIntentId, intent, 0);

How do I unsubscribe a LocationListener from recieving updates from the LocationManager?
mLocationManager = (LocationManager)this.getSystemService(LOCATION_SERVICE);

public void onLocationChanged(Location location) {
Log.i("LocationListener", "Logging Change");
}
}
mLocationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER,
5000, 1, mListener);
After I have exited the the view that created the LocationListener I am still getting log messages in the LogCat window. I understand that this is because I am orphaning the listener but I cannot see any destory method on the LocationListener nor can I see any "remove listener" style methods on the LocationManager object.
i need to know about the LocationListener() working in the real time. Does it expect the user(device) to move in order to update the current location details or it automatically updates when ever the gps is enabled?

I'm writing an application which connects to a back office site. The backoffice site contains a whole slew of JavaScript functions, at least 100 times the average site. Unfortunately it does not load them, and causes much of the functionality to not work properly. So I am running a test. I put a page out on my server which loads the FireBugLite javascript text. Its a lot of javascript and perfect to test and see if the Android WebView will load it. The WebView loads nothing, but the browser loads the Firebug Icon. What on earth would make the difference, why can it run in the browser and not in my WebView? Any suggestions.
More background information, in order to get the stinking backoffice application available on a Droid (or any other platform except windows) I needed to trick the bakcoffice application to believe what's accessing the website is Internet Explorer. I do this by modifying the WebView User Agent.Also for this application I've slimmed my landing page, so I could give you the source to offer me aid. package ksc.myKMB;
