Can someone tell me, what is the best way to deal with situations when there is no GPS signal or from some reason fix cannot be acquired?
The thing is that I thought that it would be sufficient just to use onStatusChanged method from LocationListener, but when there is no GPS signal it never calls this method. Why is that?

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.
The GPS on my Android phone is on, supported by the fact that :
location_manager.isProviderEnabled(LocationManager.GPS_PROVIDER)
returns true. Yet, the following line: Location location = location_manager.getLastKnownLocation(LocationManager.GPS_PROVIDER); returns null.
in 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 RelatedSo I'm trying to sample the gps coordinates just once in an application. I don't want to create a LocationListener object to constantly get gps updates. I want to wait until receiving the coordinates, and then proceed on to another task.
Here is a code snippet
CODE:.................
The loc variable is always null in the emulator. I tried using the command "geo fix latitude longitude" to set it, and also I tried using the DDMS way of setting it. Neither method had any effect on the code. Also the snippet isn't causing any exceptions.
I 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.
Do the Android users have the chance to reset the NetworkProvider, so that the location will be null?
I came up with the idea, that its only possible to have that location null, after starting the device the very first time. But also than google will check the location right away for my opinion.
Sure, I'm implementing a default location for this rare case. I just want to know how seldom this case is.
I have an android application using LocationManager get the cell network location and not the Wifi location? If I have turned off the Wifi antenna and do the following:LocationManager lm = (LocationManager) paramContext.getSystemService(Context.LOCATION_SERVICE);I am always returned the Wifi location and not the cell network location. I want it to return the cell location since I have moved fromthe Wifi location. I tried using a LocationListener but that doesn't seem to help.

My issue is that when I exit the app, the GPS continues receive updates. As far as I can tell the app never stops running, it just no longer displays the map activity.
I have to be missing something important.

Anyone know if I release a test version of my app to some BETA testers without publishing it on the market, and later publish it on the market with an updated version number, if the BETA testers will then get a notification from the market that there is a new version available?

View 4 Replies View RelatedEarlier today, we released updates to several different components in the Android SDK. Xav announced these updates via the Android Developers blog: http://android-developers.blogspot.com/2009/12/android-sdk-updates.html. If you want to follow the blog via Twitter, you can now do so via [url]
In addition to the new tools and platforms, there's one other important change that I wanted to point out. We've added additional clarification to the docs about android:maxSdkVersion and what effects it might have on your app if you use it. You can see these details here: [url]
We have a variety of devices for testing purposes, and now that Froyo is being pushed (to the Nexus One so far at least), we have to constantly dismiss upgrade requests. There is no apparent "stop asking me" button.
So, is there any way I can disable OTA OS updates? We want a number of these phones to stay on old OS versions.
I am developing a small app that works as a speedometer with a build in histogram.
But it is quite unresponsive, I test it by driving in my car, and when i go from 80 to 0 it takes about 4-6 seconds before my needle is updated.
For simple outlier removal, i use a 1x3 median filter on my estimated speed the speed. Wich obviously will give me a delay one 1 sample.
******* Here's the real question :) ****** I thought i might get updates every second, and thus a delay of 2 seconds, wich wouldn't be to bad. but is GPS really that slow? or am i doing something completely wrong? *******
I have registrered a listener like so:

To have a steady update of my speedometer, I use a timerTask to poll the listener for the last estimated result, and updates my speedometer view.

Does an app developer need to do something peculiar in code to get a newer version of an uploaded app to show up in the notification bar on installed users' phone?I am reading comments that vary wildly and I can neither determine if the message content I am reading is relevant or current.With the pace of change in Android, perhaps we should filter messages older than a year from results? :)
View 7 Replies View RelatedI am curious about the procedure for updating an app that was acquired off the market. Do you simply install over your existing app? And if so, what happens to your existing data?Is there a way to tie your installed apps to the market, so it can automatically check for updates? Any information is appreciated.
View 2 Replies View Relatedlately i've been receiving reports of failed updates (e.g. myTouch 3G, HTC Incredible) for my app. After the 'failed' update, they're saying they're able to launch the app only from the Open button in the Market, but not from the app icon. Is this happening to other devs too?

View 4 Replies View RelatedHow would one manage continuous updates to translations? I.e., when releasing a new version, you wouldn't want your translators having to manually copy and paste existing translations from the previous versions, or worse, re-translate everything. Even when for those languages that I translate myself I noticed that when introducing a new string, I basically need to update all the language-specific resources right away, or I will have trouble later on trying to come up with a list of everything that changed.
I'm familiar with gettext, where this problem is solved by basically being able to merge the diff between Original-V1 and Original-V2 into Translation V1.

We are trying to find out how to backup the phones before installing ROM updates.
The main thing we need backing up would be the contacts/messages and email but it would also be nice to have a backup of the applications to save all the time its going to take finding/downloading and reinstalling them?
Whats the best way to back up the phone's?
