Android :: Network Access When Phone Sleep
Mar 21, 2010
I'm using a combination of alarm (set with AlarmManager) and background service to periodically synchronize data in my application. The only problem I have is that when sleep policy terminates Wi-Fi connection the synchronization no longer works. Is there a way to "wake up" the Wi-Fi connection that has been put to sleep? GMail somehow manages to do that because it notifies me about new e-mail even if the phone entered sleep mode.

I am on a debranded Orange handset running Android 2.2. Had the phone for around 4 months without issue. I went to London last weekend and started noticing problems with the mobile internet. I was largely relying on it to get me around but the mobile internet is playing up. Even if I have H or 3G signal, my phone has suddenly stopped getting internet access or i get network errors. Nothing has changed on my handset and I usually get good signal wherever I go. I'm currently in work where I always get 3G symbol. I have the 3G symbol now with both arrows animated yet my web browser won't load anything and the market place just says I have no network access. Could this be something to do with the Orange/T-Mobile merge? Or has my phone died on me?

Is it possible to create a sort of wifi lan network (i.e., make the captivate work as a local area network router without internet access)? this could potentially be useful: quick filesharing, improvised LAN for games, etc...

I am trying to use a certain wrapper of HttpClient, called HTTPRequestHelper with an associated responseHandler as the basic class for my wrapper to a web service which is implemented as a singleton.
HTTPRequestHelper and samples of usage are described in chapter 6 of "Unlocking Android" published by Manning.
My problem is that invoking both the helper and the handler from a thread started on the main UI thread (either from an AsyncTask or directly) works only sporadically.
Here is the basic setup.
public class APIService { private ArrayList<Something> myThing;
CODE:.................

I've noticed very poor performance in the emulator (1.6 and 2.1) when trying to complete the forth statement below. It will take 5+ minutes running in the emulator. Interestingly, when I debug on my phone it's not nearly as bad at maybe a minute or so, but still not great. Running the app on my phone without debugging yields great performance (seconds). URL url = new URL(CommonProperties.BASE_SERVICE_URL + "param=1"); DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance(); DocumentBuilder builder = factory.newDocumentBuilder(); Document dom = builder.parse(url.openConnection(). getInputStream()); is there something I can do to speed up network access while using the emulator? Has anyone noticed anything similar?

I have some code that uses a network connection. I create a connection by calling openConnection() on a URL object. Is there any documentation that explains how this process works? Which access point is being used? When that access point becomes invalid, will it automatically switch to another accespoint? etc. I would like to use only WiFi access points and otherwise fail even tho 3G or GPRS could be available, is that possible?

Is there a way to force all my requests to be made through my APN and not through wifi, without having to disable WiFi? I want to know if it is possible for my application to use exclusively the network access point. I'm already able to set the default network APN and to use it but for this I have to disable the Wifi first.

We are going to make the app available for .99 on the market, but is licensing it a must? We are worried about the license query bugging the user/always requiring network access. Should we definitely license regardless of our worries?

As the title eludes to.. I was wondering if I can access my DInk through my wireless home network rather than hooking it up to the computer? Sorry if this was posted earlier, I did a couple searches and couldn't find anything.

I don't have a SIM inserted. I have firmware "2.1-update1". If I connect to WiFi and go to system software updates it says "there are no updates available for your phone". Do I actually need to be connected to a network to update to froyo? I'm in Australia.

I have a problem ( but i think that's more my setup problem).
My phone: i9100g
Rom tested: CM10, SlimBean v5
Neither wifi/usb tethering are working, when I connect my phone to pc it tells me "no access to network".
I'm having same problem with different roms,so i think that i should change my settings,and it's not a bug of the rom. My default APN at "APN Type" was "default,supl". i Have changed to "default,supl,dun" but nothing,tethering doesn't work.

So I got my Captivate this weekend, and have been using it on my WiFi at the apartment and everything is working fine. But today I went to work, and now any webpage I try to access just shows up as a blank white page with the words "Access Forbidden". Other apps work just fine, I just can't visit any webpages. I'm definitely connected to 3G, with a strong signal strength. I read in one thread that clearing APN proxy settings solved this problem for them, but I can't find any way to edit the APN settings on my phone (can only view them). I read another thread that this happens to people who switch over from an IPhone; only problem is, I've never owned an IPhone. I'm contemplating giving AT&T customer support a call, but wanted to check here first to see if anyone else is having this problem/has a fix. Here are my APN settings in case this clears anything up:
Name: ATT WAP
APN: wap.cingular
Proxy: wireless.cingular.com
Port: 80
Username: Not Set
Password: Not Set
Server: Not Set
MMSC: http://mmsc.cingular.com
MMS proxy: wireless.cingular.com
MMS port: 80
MCC: 310
MNC: 410
Authentication Type: None
APN type: internet + mms
These are the default phone settings and it won't let me change any of them, although it will let me create a new APN and edit the settings of that. It seems odd that the default APN is Cingular...that is the service I had years ago, but it merged with AT&T a while back.

I should like to manipulate (copy, delete, rename..) files and folders on PC under Windows, with a script being executed on my smartphone under Android.However, i don't know the correct syntax to use to do this.I use Script Manager with the Samba addon.
If i was on a PC under Windows, i will do, by example, that in a batch :
net use \192.168.2.x my_password /USER:my_user
copy local_filename \192.168.2.xc$foreign_folder
This DOS script copy a local file on a remote hard disk.
I should like do know how to do this on my Smartphone in a script executed by Script Manager.

I have had my HTC desire for about a week now and can't access any youtube videos. I can select a video to view and it looks like it's loading but after serveral minutes the error message 'Sorry no network connection right now, please try again later' or 'Sorry, this video cannot be played. this video is not available'
My internet seems to be working although it seems very slow (thought it should be alot faster). Is there something I need to set up to be able to view the videos? I've tried using the youtube widget and also using Dolphin HD but with no luck.

I wanted to restrict an application from accessing network, so that application does not upload or download. Basically to stop rouge application from suspicious network activity.
I understand Android provides a way to limit/restrict network access for Mobile network, from Settings --> Data Usage screen. But I'm looking for a way to completely restrict network access (both mobile and WiFi networks) to any particular application.
I'm using Moto G, Android Kitkat

My company has a guest Wifi network and a regular employee wifi network that requires a password. I was wondering if I were to access the guest wifi network using my own personal smartphone, what kind of privacy would I have?
Are there any easy apps to encrypt myself while on it? I see SSH Tunnel and Connectbot, but I don't have a server.

At the first loading of flashed rom checkbox "Data Allowed" in the Mobile Network Settings ENABLED by default.
I do not use unlimited Internet therefore.
I need some flashable patch update.zip which I can flash after the rom for switching this option to DISABLE.
It is Really? Where android save this setting?

Having seen similar threads i know im not the only ex symbian user, not that i didnt enjoy my time with it but its time to move on! ive tried to see if this question has been repeated elsewhere but i couldnt so i do apologise if i missed it!
on my previous symbian devices n95 and 5800 if i used an app that required web access be that wifi or over the network it always asked me if i wanted to allow this, and i thought it was a good feature. now i just got a HTC desire and for financial reasons couldnt get an unlimited data plan from o2 in the uk just yet otherwise id be happy to let it be on all the time.
now it seems that if you want devices to connect you either have the wifi on or off, same for the mobile network. does anyone know if there is a setting or app or anything in the pipeline that might emulate this symbian function? maybe its me just being a bit funny but i found that level of control good and it didnt mean i had to go backwards and forwards turning stuff on and off. if its not possible im sure ill get used to it but it would be a good feature!
secondly i have a Ford Focus euro model with a built in bluetooth hands free to the stereo, a factory fitted option which i believe uses a nokia Bluetooth module (stereo is sony) now this really is a minor quibble but on the old phones when the bluetooth was on any incoming calls would push the ringtone through the speakers untiill i answered it
using the desire the phone still rings normally with whatever ringtone i have but it pushes a plain ring ring through the speakers, anyone know a way to change that? or mute the phone when it rings and just push the ring through the stereo?
