Android :: GPS Initialization - Finding Satellites
Nov 26, 2009
I have searched the forum for GPS but find nothing so I am posting here, move if the wrong place. I have a VZ Droid and find that the phone service has to be turned on before the GPS will find any satellites. The fix will continue to hold if I switch to Air mode so the phone is not needed after initialization.
Google has been good enough to give us European maps but if a phone service is needed to initialize the GPS the location function etc will not work in Europe. I had planed on taking the Droid to Italy next year but it looks as if it will be useless. Any workaround or is my phone "broken"?

So I noticed 2 GPS options on my Droid X. They are:
1. Use GPS satellies
2. Enable Assisted GPS
what is the difference between these two options, and second of all, can I be charged extra for its use with an unlimited data plan? The second option says something about "preferred service" so I am a little scared to use it because I don't want to get gouged on my bill.

I have next situation: After installing application it has to init settings from server. And while it is not has right preferences it has to wait. I have several receivers and service - I don't want to check for initialization in every action in these components - I think there have to be better solution.

I have a problem with a tab view on android. I am using 4 xml layout files (each a RelativeLayout) as the content for tabs in a tab view. The main.xml contains: TabHost (@android:id/tabhost) containing a linearLayout which contains a TabWidget (@android:id/tabs) and a FrameLayout (@android:id/tabcontent). If I embeded the multiple one after another in the in the main.xml everything works fine (except my main.xml is unmaintainable which is the problem I want to solve by splitting the files into a simple main.xml which defines the tab and the content frame and then push the views onto this). The code I have to inflate and insert the 4 RelativeLayout xml files into the tab content is as follows:
mTabHost = getTabHost(); View wv = null;
wv = LayoutInflater.from(this).inflate(R.layout.user_tab, mTabHost.getTabContentView(), true);
mTabHost.addTab(mTabHost.newTabSpec("User").setIndicator("User").setContent(wv.getId()));
wv = LayoutInflater.from(this).inflate(R.layout.track_tab, mTabHost.getTabContentView(), true);
mTabHost.addTab(mTabHost.newTabSpec("Track").setIndicator("Track").setContent(wv.getId()));
wv = LayoutInflater.from(this).inflate(R.layout.chart_tab, mTabHost.getTabContentView(), true);
mTabHost.addTab(mTabHost.newTabSpec("Chart").setIndicator("Chart").setContent(wv.getId()));
// And so on for the multiple tabs.
When I run this the first tab (User) is empty and the remaining tabs have all the content from all the views. So tab2 has the content from tab1-4, tab3 has the content from tab1-4 and tab4 has the content from tab1-4. Returning to tab1 it then has all the content from tab1-4 now. The code works just fine, the events on the various objects in the views etc all are good. It is just that they are all muddled together in the view. What is causing this and how to correct it?

I am trying to make the use of Network location provider to get the location updates, But it seems to be that Network location provider makes use of MASF client . From the debug statements we found that Network provider does seems to launch MASF client , Would some one explain me the basic sequence of initialization of Network service provider ? and if MASF client is not getting initialized do we need to do some settings. What do i need to check .Any information on this is Highly appreciated.

In my app i need to read the data at a content provider before the system actually initializes. Probably what i understand is that a boot complete intent would launch a homescreen activity.Exactly before the system initialized i want to see the data provided by the content provider and use it.

I've implemented a spinner with an OnItemSelectedListener event handler. When I initialize the spinner and when a user makes a selection the even handler gets called. What I need is to determine when a user makes a selection. Is there a way to determine in the OnItemSelectedListener whether the event was triggered because of data initialization, or because of a user selection? Am I going down the wrong path trying to do this with the OnItemSelectedListener? Is there a better way to to capture a user selection event on a spinner control?

I hope to get a lot of experience on using my, for me, way too complicated HTC Desire, 1337 android users! So here's the deal. I bought an almost brand new Desire from a friend a couple of months ago. Since I just moved to another city, I was extremely fond of the GPS navigation software and the Google maps app. It was working like a charm, despite the fact that I read that the Froyo update had complicated things for some users.
Anyways, I've been using it massively, and have always been able to get a quick location and satellite fix. However, the other day - it just couldn't find any satellites at all! Since then I've been on an internet scavenge hunt for clues as to what might be the problem, and I've downloaded GPS tester and various other apps for GPS configuration and ultimately ended up doing a "hard reset" in sheer desperation. How can this be? I mean, to me it doesn't make a whole lotta sense for it to just stop working like that.

I just got my Desire last week, upgrade on Vodafone from a Samsung Omnia, and this one is by far THE best one ever. PRO: with 1Ghz cpu it runs like the wind apps:lots of them and till now haven't had any problem with any game or app, one of my favorites is AndFTP...use it to conect to my computer via wifi to get all that i need GPS: i can't belive how fast it conects it self to satelites, i haven't tested it on a cloudy day, cause it been all sunshine these days. the time it took to conect was les then 10 sec out side, and less then 30sec-1 min indoor near a window. with my previous phones N95-8G and Omnia, if it was sunny...2-3 min, cloudy-more the 5min...sometimes 10min, and indoor by the window...never...got sick of waiting more than 10-15 min. display...it's big enough network conection....never fails...full signal anyware, unlike my wifes sam jet on "3" network witch kind of suck, outside signal quite good, but indoors....is more or leass with no signal came preinstalled with a sandisk 4g microsd card very thin-for what it has inside....
-can't install apps on sdcard (why is that???is that how all andoird OS are? do i have to root it, and if so is it possible to root the desire?) low memory on the phone to install apps and games...it practicly asks for rooting wheres all the memory???...on gsmarena and other sites...at the desires specs the Internal memory si 576 MB RAM; 512 MB ROM, and i use smart monitor lite and at system my it says my memory is 398.34, and at storage (/systems+/cache+/data adds to 250+40+147=437)...can't properly close and app -no DIVX...come one...why???..

I've always kept the GPS and the DATA power on the power widget flipped on.
I would turn on BLUETOOTH and WIFI as needed.
During 2.1, the GPS would activate only if I opened an app that required it, like Google Maps.
But since 2.2, I've noticed the GPS running for no apparent reason.
No open apps, no open browser, no open maps. Nothing. it just runs on it's own. An it only started since 2.2.
I've never had to shut off my GPS before, but now, I have to keep it off and turn it on as necessary. Very frustrating.

I've done changes in an Android native library and installed a new system.img file but am now getting an unrelated Error on startup. I can get past it by swallowing the error but I wanted to know if anyone can explain what the issue is.
The Android implementation of Logger.java claims that it is Forcing the LogManager to be initialized since its class init code performs necessary one-time setup. But this forced initialization results in a NoClassDefFoundError. I'm thinking that it has something to do with the class not having been preloaded by Zygote yet but am not that familiar with the whole class loaders and VM business.

Up until two days ago, my GPS worked perfectly. Start up Maps and the GPS would lock onto satellites and give me an accurate position. Yesterday, I checked Weatherbug (uses GPS for location) and it said I was in a city in Florida (i'm in Ohio). Strange I thought, so I restarted and got an accurate reading. Immediately after that I started up Maps and the GPS could not lock onto satellites. It kept searching. Finally, that night, it started working again.
Well today, it's doing it again. It won't lock on to get an accurate position.
Like I said, everything was fine since I got the phone on launch day. Two days ago, the problems started.

Does anybody else have a problem with the length of time GPS takes to lock onto the Satellites? I can be waiting for over 5 mins where my friends GPS will pick up instantly.

So before the update yesterday, I loved my Captivate. GPS worked great as did the rest of the phone. I figured since getting the update message, I would go for it. During the update the service was pretty bad in the office so I canceled the download to continue it when I got home. When I went to continue, it automatically rebooted my phone and applied the partially downloaded FW and completely bricked the phone.
Since last night, I have exchanged my Captivate twice. Each time the phones have major issues. Forget about locking onto satellites, it can't even get any in view in the middle of the street. On my current phone, forget not being able to connect to AT&T servers for the update, I can't even connect to Android Market...
I spoke with AT&T and the CS Rep made a special note on my account that told the store to not let me leave until I have a phone that has functional GPS, updates and fixes whatever issues I have. Additionally I was offered a credit to my account for the inconvenience. Add to that the CS Rep made a note to call me on my 30th day to make sure everything is working and if not, we will see where we go from there (cancel, extend the return period...).
Now I'm not sure what to do. I will try one more exchange but if that doesn't work, I'm considering going back to my dumbphone for now... I doubt I will get an iPhone4 and after 4 Captivates, don't think I will keep exchanging.
Sorry to vent my frustrations but this has been an aggravating couple days - even more so that my bricked phone worked great in all aspects.

Menu - Settings - Location - Enable GPS satellites
It states that enabling this will "require more battery plus view of sky"
When checked, it states "deselect to conserve battery"
So, the question is, should this be enabled?
I imagine for some applications, knowing your precise location should be useful, especially if the turn-by-turn maps are installed and used.
I'm thinking to deselect this, and selecting it at times when I need it.
So, to check or not to check?

My brother has a Iphone and there is a app called pin pal lite. Its a bowling score / statistic keeper. For instance we bowl 2 nights a week in a league and he enters in what he did that frame every frame. The app breaks down how often you leave splits, throw strikes, pick up a certain pin. I was wondering if there is anything like that for the droid. I dont feel like spending 200 on a ipod touch to get this. I have looked for many hours and found nothing..

Some users are reporting that they can't find our app (WordPress for Android) in Android Market. We have it enabled for all devices and locations with copy protection turned off. One user reported that he is from Sweden (see comments at http://android.wordpress.org/2010/04/05/add-shared-text-and-images/).
I'm in the U.S. and see the app in the Market.
