General :: Why Does 2G Network Provides More Information Than 3G
Feb 22, 2012
In my application, I want to collect the surrounding cell ID and LAC on my Android phone (to estimate the location).I use the telephonyManager.getNeighboringCellInfo() function which returns a list of NeighboringCellInfo.
If the phone has enabled the option "use only 2G networks" I receive the correct list but if this option is not enabled (connecting also on 3G networks), the NeighboringCellInfo has "-1" for cell ID and LAC for the whole list.
why 3G networks provides less information than 2G ? Is there some technical reason ? Can I still get the cell details on 3G ?

I need some advices about the Android OS and application.i wonder if the Android OS is able to push network connecting status to applications.(I found applications can get a network connecting status from android OS. But I can't find reverse cases.)However, I am thinking android OS may push network connecting status to applications.when application is installed on android os, is it possible to register something for monitoring phone's network status on android os.Because I want my application can receive phone's network status from android os.(not by asking directly to android os.) It means: when phone's network status changes, does android os automatically informs phone's network status to application?I'm sorry my English writing is bad TT;

I am a Mac user (photographer/ videographer). I also rely heavily on my iPod Touch when mobile (i can often find a wifi signal when i am out and about). I use iCal on the Touch and iCal on my Mac as well as the address book on both everyday and as a Mobile Me user, my two devices sync so everything is mirrored and up to date. I also HATE AT&T for their terrible signal strength and coverage and have been a loyal Verizon customer for many years and this is why I don't have an iPhone. Okay, all that being said, is there an easy way to still use everything I love and rely on with my Mac (the calender and address book, mainly) and easily sync all of my existing information and future info to an Android based device? How easy is it to use an Android device with a Mac? I don't want to have to manually re-enter my entire address book into a new device.

We've had some people develop and application for us. For now, our application uses static data that requires a manual update each time this data changes. Our plan in the future is to have this data updated automatically the instant this new data is available.
For now, is there a way like through some online cloud that I can link the application to? So, that way when I put the data online in this service thing, the application whenever it has a data connection or Wi-Fi pulls the new data?
For the future, what's the best way to set up this automated updates?

I am recently doing a graduate research on the accelerometer in mobile devices. Accelerometer is a MEMs device built in almost every smart phone nowadays. I am interested in finding what information does the hardware accelerometer report that the software knows the raw values X, Y, Z to detect the orientation in which the phone is held?

Where password information is located in the system? Like password information from the browser and other apps. Is it just the app data or is there extra information on the phone?

I love weather apps, but I've yet to find one that I really like that much. A lot of them are pretty good, some have this function or that function but none of them seem to have everything.
Anyway, years ago I used an app called PocketWeather on Windows Mobile and used a skin called Wonder Skin. It looked like this:
Notably it has humidity, pressure, forecast, current conditions (inc wind), temperature graph etc.. It had everything at a glance, I rarely needed to look into the app at all for this.
Most weather apps I can find today just have some current info, mostly seem to be clock widgets + some weather info.
Any weather widgets with more details on them? I don't really want to get into the complexities of making my own with something like UCCW but I'm pondering it.

How can i get device information from nonrooted device with python script? As I understand python don't have API like os.android.build in Java.
I need to get system information from device, such as cpu frequencies, gpu vendor and other (like in Antutu and another benchmarks).
I know how to write python script with $getprop information from shell, and from buil.prop file in the system files, but it isn't enough. I also know how to get these information with shell command and busybox installed, but I shouldn't root them.

I am in process of developing an application and I was wondering if there is a way to capture users information automatically. I am drawing up a spec of application functions that I am going to have a dev team produce so I do not have app dev skillsets. That being said...
My idea was that if an user downloads an application, starts it, and the app is automatically populated with the users' phone number, name, etc any basic information automatically. Google pairs the phone with specific accounts that store such information so the data is there. I am looking for a less intrusive way and more user friendly way of creating accounts rather than direct social media login integration.
Is this something that is viable? or is it against data laws? or not possible?

the play store spits this error at me constantly. It happens when i download apps from the play store. It says "Error retrieving information from the server [RPC:S-5:AEC-0]". Just to clarify, things I've already tried: wiping data of play store and play service frameworks, wiping dalvik and cache, deleting my host file and readding my Google account. I've added another account and it downloaded apps flawllessly so it must be my main google account.

When using my sms app, I am looking for a way to display which phone number of my contact is used (mobile, work, home, ...)
The only thing showed is the contact name and his phone number.
With all the sms apps I've tried (stock, hangouts, hello sms, 8sms, evolvesms, chomp, handcent), I didn't find a way to display this information. I always have to do an extra action (clik on contact photo, or title bar) to check if the phone number concerned is 'work' or 'mobile'.
Any tip or a new app to show this info ?

Isn't there a way I can get contact information I find on the web into my Android phone book without having to pull out my phone and typing it in by hand?
I thought there was a way, maybe I had to add something to my computer where I could type highlight the name, address and phone number, right click up a menu and have it all added to my phone book.

I have been looking at the ConnectivityManager class documented at http://developer.android.com/reference/android/net/ConnectivityManage... .
I would like to know if an Android application can open a network connection (socket) on a specified network interface [on a device supporting multiple network interface types WiFi, Cellular, WiMax etc] ? I am looking for the capability for an application to open a socket on a given type of network for example over WiFi network or over 3G Cellular Data network.
If this is possible in Android, how would I code this requirement within the API Framework ? The ConnectivityManager enables an application to learn about available network connections and currently categorises them as either TYPE_WIFI or TYPE_MOBILE.
There is a member function in the ConnectivityManager class called requestRouteToHost(int,int) [url] which "Ensure that a network route exists to deliver traffic to the specified host via the specified network interface. An attempt to add a route that already exists is ignored, but treated as successful." Sounds like this would install an IP routing table entry to reach a given host via a specified network interface type (WiFi or Mobile). After calling this would it be sufficient for an application to open a socket and connect to the desired destination address ?
Or perhaps the application needs to bind() a socket to a local address of a network interface of the desired type (WiFi or Mobile) Or by setting a socket-level socket option of SO_DONTROUTE ?

I seem to be seeing an issue with the data network access on the EVO. When it happens none of my applications get internet aceess and my mobile network status says "turning on". The only way I've found to fix it is to pull the battery. Any one else seeing this? If so is there a better fix than pulling the battery?

My eris has always has pretty alright battery life, what I would expect out of a smartphone, if unplugged at 9AM it usually was running on its last leg around midnight. I've had it for over 5 months now, I've always had it activated on alltel, I installed the 2.1v3 leak before the official OTA was out and just lately it seems like there something very wrong with my battery life...
If I unplug my phone at 9AM within the past week and occasionaly check and respond to a text message, my battery had been down to almost 30% by NOON... what?..
I have noticed that if I disable Mobile Network (3g/1x data), the thing lasts all day and some... If I turn mobile network ON, I can't see that I have any network traffic or any apps running in the background that are syncing data at all... I've had google account sync mess up on me before and have to reset my google account because it gets stuck in a syncing loop, but its not doing that, already checked. Very weird.
Anyone thing it could be something wrong in my ##PROGRAM#/##778# provisioning menu, maybe something got changed?.. Maybe it could be do to Alltel's AT&T merger that's happening right now, maybe some 3G tower's radios are turned off or something...

I'm wondering if, with the G1, it's possible to force the network traffic to pass through the Wifi or through the Cell GSM network. I need to force an application to connect through the tower network to get some login information. Is this possible? Anyone have any ideas as to how this would be possible? I'm trying to accomplish this inside an app with the Android SDK (Sorry I wasn't more clear about that originally)

I alternate between two wifi networks on my HTC Desire running Android 2.2 ( I think!)On one network I need to specify the network IP/subnet/Gateway and so on, on the other network I can use DHCP.Is there any way to tell Android that whenever I connect to one wifi network it should use the static IP and on the other it should get an IP automatically?I am forever going into advanced wifi settings and changing them back and forth. I'd love for my phone to remember the settings used on each wifi profile.

do you know how to get the Home country code, current country code, the Mobile directory number on a cdma network. I see TelephonyManager.getNetworkCountryIso() can get the current country code, but it is not reliable on cdma network.

I have been trying to find a way of quickly switching off/on the Mobile Network setting from the home screen. When searching Google there's loads of pages stating that it is an HTC Widget that can be added. I have checked all the widgets on the Desire HD and cannot seem to find it anywhere. I am using an unbranded handset.
The Desire HD manual even states "You can also add widgets that allow you to quickly switch on or off certain settings of your phone, such as Wi-Fi, Mobile Network...".
Does anyone else with an HD handset have this widget ?

I got a chinese X12 dual sim phone because i really needed only 1 phone (had to carry around 2 of them).Phone works great, only problem is with the mobile networks. It can connect to GSM networks but it won't connect to a 3G network. The phone has 3G capabilities, 3G is enabled for the required sim, it finds the 3G network but it will not connect to it.
Sim works fine, had it in a Samsung i900 on 3G (WCDMA) The thing that surprises me most is that the phone came with android 4.0 instead of the 2.3.6 it was advertised, could this be the problem?
