Android :: How To Check If GPS Signal Is Available / Not?
Jul 6, 2010
Can anyone tell me if and how it is possible to check if the GPS signal is available or not. So not wanting to know if gps is enable or not but if a signal is received. GPSstatus doesn't seem to be about that nor does the onStatusChanged of the LocationListener. At least it doesn't seem to report the signal. What I try to do is display an alert when signal is lost (when driving in a tunnel) and hide the alert as soon as the device is receiving the signal again. So it's not only about the firstFix but every time the signal is lost or back again... Probably not the only person in the world wanting to know this ;-) and it should be possible since the gps icon in the phonedisplay is doing the same.

I want to reach out to others here before I take my Moment back to Best Buy to exchange it for another Moment.
My signal strength fluctuates wildly just sitting in the same spot. With the Hero I got a constant 5 of 6 bars, but the Moment will vary between 0 and 5 of 6 bars. But it's more complicated than that.
It seems that whenever the EVDO data kicks in, it causes the signal strength to drop to 0 or 1 bar. Once the data is idle, the EVDO indicator turns grey and then changes from EV(^v) to EV(D). At that point the single strength will return to 3 or 4 bars.
At times, though not as consistently or often, the EVDO connection will fall back to 1xRTT and will switch between them every few minutes. This will occur even when the signal strength bars are in the 3 to 4 range.
So, the my questions are...
Does the signal strength apply to the data signal or just the voice signal?
Is there any legitimate reason for the signal strength to vary wildly like I've described, even when sitting in the same recliner where the Hero had a constant 5 bar connection and data service that never wavered?
Is anyone else having signal strength and/or data service issues?
Should I exchange the Moment for another Moment or will I likely experience the same issue?

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?

I can get a few minutes of 4G signal at my home per day, but when it drops out and 3G takes over, the signal will flatline and boot me offline. My 3G speeds are usually around 56-150Kbps or less, and my 4G speeds are around 2.5 Mbps What would cause this ? According to WiMax location sites online, my nearest 4G tower is .52 mile away. I would think that if I actually get 4G signal, then 3G would be constant. Turning off 4G doesn't help either. Is there some setting that I could have turned off that would cause this ? Running stock EVO on 2.2 all the latest updates

I'm writing an android application that collects cell signal strengths. I am having trouble getting the "current" cell signal strength, but I don't have any problem getting the "neighboring" cell signal strengths. To get the current cell signal strength, I created a PhoneStateListener and implemented the onSignalStrengthChanged callback. It works, but not very well. It seems like the signal strength hardly ever changes, and resolution jumps to only a few numbers. I would accept the answer that the resolution of the signal strength hardware is coarse, but when I use the TelephonyManager's getNeighboringCellInfo() method, it works much better. The signal strength readings from neighboring cells change frequently, and they have much better resolution.So, how can I get the current cell signal strength in the same way that I am getting the neighboring cell strengths? It seems odd to me that the functionality of the neighboring cells is better than the current cell. Am I missing something here?I would also like to directly call a method from the telephony manager to get current cell strength, as opposed to a listener, if possible. If anyone knows how, please let me know.

My droid x signal pretty much always between -92dBm and -87dBm with 1-3 3g bars. My former droid eris would get -92dBm with 1 bar and also drain incredibly fast.
On the droid x, if I go into google maps, the circle of the cell tower appears and the place I live at is half way within the edge of the circle and the other half is outside of the circle. I always seem to be connected to this tower. Bad luck I guess that I'm on the outskirts of the circle.
Does anyone know how cell towers are distributed? Do they overlap sometimes?
I run pandora with the screen off for a half hour with the screen off and my battery is down to 70%. I have about 15% screen brightness and battery saving mode on.
yesterday, I was on meebo for an hour and 45 minutes and it was down to 60% from a full charge.

I haven't really concerned myself with app piracy; I only have one app under my belt for Android, it's in beta and it's free. I'm about to start development on another app and looking to use ProGuard for obfuscation and LVL as I would like to make it a paid app, and I've been wondering something ever since the news that LVL had been circumvented months ago.Is it possible to check the .apk's signature from within the API? If not currently, perhaps Google might add some code to Android itself or to the API to enable LVL to make sure that the.apk signature matches the signature that Android Market already has on file?

If you guys haven't heard of the app called Shazam, YOU HAVE TO TRY IT.
Its just Track ID for the Sony Satio but FREE!
Imagine you are in a club and there is a track you like, use this app and it will tell you who its by and where to download it!
I just downloaded it but it hasn't failed me yet!

I'm writing a mapping application. In simple terms, it sends some info about the user's current location to a server when the user clicks on a button. I need the location to be absolutely correct, and when I first started to implement LocationListener, I found that it often wasn't. So I've used location.getAccuracy() to check the GPS accuracy, and warn the user - without submitting the data - if the location isn't accurate enough. Code...

I'm guessing that the GPS hardware in most Android phones is the same or close. If it makes a difference I have the Moto Cliq XT.I'm going hiking tomorrow and will be using Google's My Tracks program. I've tried it twice... the first time I could not get a signal despite being out in desert with nothing to block the signal. Next time I was in the mountains and once I had a signal, it was rock solid. Worked like a charm. But I did not want to take a chance and held it in my hand the entire time. I'm wondering if anyone has tried it while the phone was in their pocket. Any issues with sat lock on? This would be much easier. I also can't imagine that you'd not be able to use GPS while the phone was in your pocket as it's not really possible to have it in your hand all of the time.

I am assigning to an ImageView contacts images using this code:
mPhotoView = (ImageView) findViewById(R.id.photo);
mPhotoView.setImageURI(objItem.getPhotoUri());
If the contact has no image, this does nothing, and no error is raised.
When there is no image, I want to add a default image. So I need to check either if the image was added to the view, or check that the URI holds some image data
Than I will set default image by this:
mPhotoView.setImageResource(R.drawable.ic_contact_picture_2);

I have google voice. And the quality is excellent but im on a non data plan so I can't check it out in 3g. I live in a t-mobile edge zone so I want to know about the voice quality & reliability cause I'm planning on getting a nexus with a t-mobile data only plan. Will it be like a regular phone call or will I have poor quality?
