Android :: Turn Off GPS Icon When LocationListener Is Sleeping
Jul 26, 2010
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?

I've created service which has LocationListener in it. In order to keep service running the service is set as foreground. I have some questions about phone power management and sleeping in that circumstances: Will phone go to sleep while such service is running? How can I save power in this stuation?

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 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?

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?

I 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 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.

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.

i need to know about the LocationListener() working in the Android DEV Phone(ADP1) 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... (ADP1).

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

Here's my scenario. I have an app that is playing backgound sounds. Using the BroadcastReceiver I can tell when the display turns off, and then kill the sounds. I can also tell if the screen turns back on. However, if the device is in the lock state I don't want the audio to start. Therefore I wait for the ACTION_USER_PRESENT intent to signal. That all works, except that if the user turns the screen back on quickly after it was turned off, you don't get the lock screen or the ACTION_USER_PRESENT message. So, is there a way to tell, when the screen turns back on, if the device is locked or not, which I guess also means sleeping or not?

Often my mobile network is turned off and I just use a Wi-Fi hotspot.
If the phone is not plugged in, the Wi-Fi connection will go to sleep after some length of inactivity.
I could be wrong, but a call to ConnectivityManager.getActiveNetworkInfo().isConnected() does not wake the connection.
So, what is the best way to wake the connection?
In general, I'm looking to write an isConnected() method which will return true/false, optionally blocking returning until a wakeable internet connection is awoken.

I'm making an application which will utilize both touchevents and sensorevents. The problem with touchevents is that they fire off very often, and thereby consumes massive amounts of CPU time. The common solution is to do a Thread.sleep to make it cool down.However, if one wants to use both the onTouchEvent and onSensorChanged in the same activity, applying the Thread.sleep hack will also slow down onSensorChanged. This is obviously caused by the two methods being called from the same (ui) thread.Is there some way to call onTouchEvent from a different thread than the ui, so one could do the Thread.sleep trick without slowing down onSensorChanged as well?

Why do so many of the applications say they prevent the phone from sleeping? Is this a problem if the applications are left open or a problem with the applications all of the time no mater if they are open or not?

I used to have a BB Tour. I could set it up to turn off notifications for email and text messages when I had the phone plugged in. The phone would still ring. I am looking for an app for my HTC Incredible that I could do basically the same thing. I would like to set the phone up so when I'm sleeping the notifications for SMS/MMS and EMAIL messages are muted, but the ringer for the phone is still active. Does anyone know of such an app or setting to do this?

I have a long lived service, it wakes up (via the AlarmManager) at intervals and connects to a web server. If the phone goes to sleep and one of my polling intervals happens the phone wakes up enough to let me attempt to connect to the network but the ConnectionManager claims there is no network. Given the system log this is correct, it was torn down. Pushing "Menu" once is enough to get the network back up and then my service can connect. How do I get the network to reconstruct itself?

I noticed that if the Android phone is listening on a ServerSocket on the 3G network, and is then put to sleep with the power button, it no longer listens for incoming connections. The incoming TCP connection does not wake up the phone. Is this there a way to enable waking up a sleeping phone on incoming Server Socket connections, the way that incoming data on a regular Socket does?

I have noticed that when display goes to sleep, my TimerTask is also freezed, until display is waked up. I need my TimerTask to execute (a BlueTooth operation every few minutes) even while the display is sleeping.
How do i achieve this (eventually using something else instead of a TimerTask)?

I took the plunge and finally rooted my phone (hand clap!!). I flashed a custom kernel (by NETARCHY[4.0.3a]). At 1st everything worked fine (followed EarlyMon's "How to Fix FROYO"---since i lost all my data). The following day i tried another kernel (baked kernel #5). That kernel didnt work to well on my phone so I reflashed NETARCHY's kernel. When i noticed that my battery was draining quickly, i looked in my SPARE PARTS and noticed that my phone is not sleeping---problem is I dont know what it is. Do i need to do a hard reset again---or should i flash another kernel?? Stuck between a rock and a hard place
(Mods--did this in a rush, please excuse if this is posted in wrong forum)

A few days ago I after reading some threads on reboots and decided to check the awake time and found that phone wasnt sleeping. Battery life wasnt affected all that bad I thought, lasting throughout the day, however I did an FDR reloaded only a few programs and the problem went away (along with the reboots that occurred nearly everytime I started navigator and only navigator). Battery life was exceptional afterwards, still having at least 60% remaining after unplugging around 8 am and checking later than 7pm
I reloaded the following apps
Shazam
xing barcode scanner
LED desire
Google Earth
Spare Parts, and just now sys panel lite.
Today I experienced another reboot, checked awake time and found it to be at 100% again. After unplugging at 8am and checking at 7 pm, battery remaining is at 36%, way under normal (im usually at 60%+ with heavier usage). Very moderate use today , maybe a dozen short calls, a couple emails, no browsing, took 1 picture and sms'd it, and LED desire (first time used since re-installed) I do keep both my wifi and BT on, 4g off. Ive been in good signal range all day.
