Is there a way to manually trigger the code inside a LocationListener's onLocationChanged method? It should receive a Location object with the last known location, I guess.

The App I'm trying to work on requires that when a special combination of keys are pressed ( irrespective of the keypad being locked ) a service / app is triggered.
How can I achieve this? My app's whole idea hinges on this particular part to work.
I am not here to take a "no" for an answer. If you are going to tell me that its not possible, atleast include an explanation as to why its not possible.
Is there sync object on android similar to manually reset event on Windows?
It must have signaled and non-signaled state both set manually. A thread must be able to wait on it and wait would return immediately if the object is in signaled state and block if it is in non signaled state until another thread sets it to signaled state. There must be way to reset the object back to non-signaled state.
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).................
Perhaps I'm misunderstanding how Intents and intent-filters work, but it seems to me that this should be a strait-forward case. However it's not working. Here is the Intent I'm sending:
Intent i = new Intent(Intent.ACTION_VIEW);
i.setType("vnd.android.cursor.item/vnd.connectsy.event");
startActivity(i);
And here is the intent-filter:
<activity android:name=".events.EventView">
<intent-filter>
<action android:name="android.intent.action.VIEW" />
<data android:mimeType="vnd.android.cursor.item/vnd.connectsy.event" />
</intent-filter>
</activity>
And finally, the error I'm receiving:
android.content.ActivityNotFoundException: No Activity found to handle Intent { act=android.intent.action.VIEW typ=vnd.android.cursor.item/vnd.connectsy.event }
I've noticed that no apps are running according to Task Killer. I do NOTHING on my phone and look at Task Killer again and see that several applications are NOW running in the background. Is there anyway of learning what is triggering them to launch ?

View 1 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 RelatedWondering here if there is a way I could trigger an event, so that any library listening for these events (e.g. jQTouch, Sencha touch, iUI, ... ).
If I could extend or use jQuery for such task e.g. $(...).trigger('event') that would be great to know.
Usage example:
I need to debug a few web apps by simulating multi touch with my mouse. This seems a little complicated, so if I could trigger the multi-touch events using Javascript I could therefore test the app more efficiently.
I've recently done quite a bit of work on saving instance state and restoring using parcelables for custom data structures. My problem is that I don't know how to test this functionality on the emulator. I can trigger calls to onPause and onStop for my activity (if I navigate out of it) but never onDestroy. So, whenever my app starts up, it starts with a null bundle. I've never had onCreate with a non-null bundle and I've never had onRestoreInstanceState getting called. how I can test the restore state functionality from the emulator?

mLocationManager = (LocationManager)this.getSystemService(LOCATION_SERVICE);
mListener = new LocationListener() {

Log.i("LocationListener", "Logging Change");
}
}
mLocationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER,

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? Another query is regarding the getLastKnownLocation(). When is that last known location will be lost and thus returns null... (in realtime).

Is there a way to determine exactly who is generating that WL? It's not related to GTALK, as the WL name incorrectly leads us to believe, but it must be google, and I only see it fire when the Wi-Fi is connected and in use. It's non-existent when I'm on Mobile. It comes and goes, sometimes chugging wake time like its cheap beer, othertimes it's dormant, and I haven't been able to figure out who is using it based on the context of when it occurs.
There HAS to be a log or something somewhere that says process X is responsible.
I hope there is a way to resolve this or bye bye hero.
View 10 Replies View RelatedI made a bit of a mistake when updating to the latest Android SDK. I downloaded the SDK Manager manually, then downloaded the 2.0 (and 1.5r3) platforms, and only then updated Eclipse...and realised I probably should have updated it all from the ADT within Eclipse. So I am currently stuck with Eclipse not able to see the SDK's I downloaded to the SDK Manager.
How do I add those SDK's the ADT, or do I just have to re-download the SDK from within Eclipse (which seems like a real waste).

View 1 Replies View RelatedI am trying to update an AppWidget manually when a user setting changes on the device.I can tell that my AppWidget onUpdate method is being called as a result since I log some debug strings to logcat in the code. However the AppWidget itself doesn't change on the screen.Here comes the interesting part: if I rotate my device and force a refresh of the home screen (from PORTRAIT to LANDSCAPE or vice-versa) then finally my AppWidget gets updated. However rotating the device does not trigger the onUpdate method to be called, so the AppWidget must be using the RemoteViews provided in the earlier update. Can somebody explain me what to do to force the home screen redraw of my AppWidget when it processes an update?
