Any one else got the same problem?

However, my phone will not connect to the google server - thus I cannot get my contacts or calendar, and cannot get to the market. The message I get says: 'cannot establish a reliable data connection to the server'.
I would like to implement a functionality in my game to give some daily goodies. But user can easily abuse it by changing the date of the device again and again. I know this can be easily implemented through some server. Is there any way to handle it locally without the involvement of server or network connectivity?
View 2 Replies View RelatedI am new to developing applications for android but have developed my first app. I have following questions.
1. Is it possible to create a client server app? I mean the application on one phone acting as server and applications on other phones sending/receiving data from it?
2. Create a wifi network (may be using bluetooth) for the above client server app. The idea being not to use the mobile service provide network but rather a local network.
Hi, i am very new to programming in java however have a lot of experience in .NET (c# & vb.net). I am trying to create a new instance of a serversocket class in eclipse IDE and when i type the following code it is giving me an "Unhandled exception type IOException" and i havent even tried to run the code yet! I dont understand how my code is exceptioning before runtime or what i can do to fix it.
View 2 Replies View RelatedIs there any build-in mechanism in Android, which could create a service or app that actually listens to some server from the out side.. something that will "Wake up" the phone and makes him receiving a message from an outside server (i am asking this coz most of the appz are working the way around, when the phone sending requests to an outside server to receive data)
is it possible any how?
I'm working on a litte HTTP server application for the Android. Now I like to secure the communication by using SSL. But I got stuck by creating a suitable keystore file. Searching the archives I came to the conclusion that it will be best to use a BKS type keystore since all other keystore types (like JKS) are not supported on the android.
Unfortunately I can't figure out a way to setup the keystore file. I tried OpenSSL - wrong keystore format. I tried the keytool from JDK - right keystore format but it doesn't support BKS keystores. I tried the Keytool IUI - I could create a BKS type keystore but it alwais ends up in an InvalidKeyException "Illegal key size". No matter if I try to create a new certificate or import it from a JKS keystore. (I tried to create the RSA ver.3 certificate with a key size of 2048 and 1024 bits.) How do you create BKS keystores?
For completeness here's the code I trying to use for loading the keystore:..............................
Anybody notice they are losing their Internet connectivity while tethering with 2.2 Roms. I have run BB, Kangerade, and CM6 rc1&2 with them all losing Internet connectivity completely. I have tried different kernels and different baseband all resulting in the connectivity loss. Is this a hardware problem with the phone or is it software based. This is a somewhat new phone and I honestly can't remember my previous one giving me this many problems while running 2.2 roms when they first came out.

My application has some code which detects if the Android device is connected to a Wi-Fi or Mobile network.
The code appeared to be working fine for Andoid 1.5, but does not seem to work correctly for Andorid 1.6.
Here is the code I am using:
CODE:..........................
Under Android 1.5 this code would correctly detect if the current connectivity was Wi-Fi or Mobile. However under Android 1.6 the call to getActiveNetworkInfo seems to always return a networkInfo instance with the type set to TYPE_MOBILE. This is happening even though the icons in the bar at the top of the android screen show the Wi-Fi connected icon with the full signal strength bars showing.
I don't know if this means that under Android 1.6 it is actually using the phone data network for connectivity instead of the Wi-Fi connectivity when both networks are available, or if the getActiveNetworkInfo call is just returning the wrong information for Android 1.6.
Has anyone else seen this issue with Andoid 1.6? It would be too bad if 1.6 is really using the bandwidth on the phone data network instead of the Wi-Fi network when both networks are present. Does anyone know if there is a different way to correctly detect if the Android device has Wi-Fi connectivity?
I am with first Droid phone. I have had an HTC Desire for approximately 1 week and absolutely love it. When I first got the phone, the connectivity was always H in the status bar, with very good I-net speed. For some reason, unbeknown to me, it is now a G, sometimes a 3G. The speed is still quite good though. This 'change' would appear to have been since I received a text from T-Mobile (I'm aware of the 'G' issues on their forums) alongwith the lines. They hoped I liked their new webpage. Now they have reverted to the original webpage I may have to re-load my favorites. I have not had to do this, thankfully. Under Wireless & Networks, WiFi is off, as I am on an 'unlimited' 3GB plan, and I am using GSM/WCDMA auto under Preferred network mode.
Questions: -
1. What is the difference between the three, namely H, 3G and G?
2. Which is quicker?
2. Can I change it back to H, if I wanted, as I believe it was quicker?
4. Sometimes, although not very often, the G, 3G and H disappear altogether and I am left with no connectivity at all. However, if I try to access the I-net, I can, and either the G, 3G or H appear again miraculously. Is there a particular reason for this?
Hope to hear from you experts soon and apologies for such basic questions, as I'm still getting used to using a droid. My last phone was a Nokia N95 2GB. Huge difference!
We are developing an Android application that uses bluetooth to connect to a board that we developed. If we try to connect to the board after the system has been off for a while, the system connects correctly and begins to stream data. The data stream will freeze momentarily, then start, then freeze, then shut off after about 6 - 8 seconds. If we try again it will repeat this process. It is almost like the Android is checking to see if it is an ok device to connect with, and decides no for some reason.
The only way we have been able to then connect again is to un-pair and then re-pair the tablet to the board. After we unpair and re-pair, the connection works well and will continue to work well until we turn the tablet off.
I need to do the same thing i do with connectivity but in my phone, i connect to the web with my wifi and share internet with the same wifi adapter.
i been looking into it for a while and people keep on say that i need 2 widi adapter for it but is SO no true coz i have and use only 1... I don't wanna use bluetooth at all or connect it with usb.
I am currently in China and therefor run a VPN on my PC to connect to the outside world, I would also like to run the same VPN (PPTP) on my android. I can connect via VPN if I am using WiFi but when I try to connect over GPRS/Edge I can't get any connectivity. All web pages load with the standard "web page not available" and apps, eg. the market place, won't connect either. I would have thought that if it was a carrier issue (CMCC) I wouldn't be able to connect to the VPN in the first place. So is this a Android issue, a setup issue or a carrier issue? And can you actuality run a VPN over GPRS om Android?

I am using this code in an android project. Now the problem comes when there is no internet connectivity. The application just halts and later gives error. Is there some way to break this after some fixed timeout, or even return some specific string after an exception is thrown.
I have an IntentService which makes some web service calls. Before making these calls I check to make sure the device has network connectivity.
I am doing so like this:
CODE:.............
Unfortunately, when I'm debugging on my Android device, this returns false when I have both a network and a wireless connection.
Some interesting tidbits about connec.getNetworkInfo(0):
CODE:...................
Clearly this code is not sufficient (perhaps it would only return true if I sent some bit over the network and turned the radio on?). Moreover, since I'm not well versed in the ConnectivityManager, I'm assuming I should probably be scanning all networks (ie: getNetworkInfo(0 through N)).
I am working to send request to internet and get data, my emulator show the 3G sign on it, i have also sent the permission to internet connectivity in my app. But when i click on button to send request it return null. I have checked the request link in chrom it send data successfully.

This works fine in the emulator running version 1.5 of Android when 3G is enabled, but it crashes when I disable the 3G connection. My application throws a null pointer exception when I call isConnectedOrConnecting(). The same thing also happens on my HTC Desire running Android 2.1.
My chat application connects to a server and information is sent/received by the user. When the connection changes, such as 3g->wifi, wifi->3g, losing a data connection, etc, the socket sometimes stays connected for ages before disconnecting. During this time, it's impossible to tell if the connection is still active, it seems as if messages are being sent just fine. Other times, when sending a message, it will throw an IO error and disconnect.
Apart from implementing code to detect connection changes and reconnecting appropriately, is it possible to have the socket immediately throw an IO exception when connectivity changes?
I'm connecting using the following code:.........
I'm not using setSoTimeout as data may not be transferred for long periods of time depending on the remote server's configuration.
I am trying to check internetconnectivity in android and using following code

But it gives me network/ wifi connectivity if wifi is connected it gives me true and if internet is not connected then it also gives me true.
Anyone else lost 3G? My phone is fine cause I haven't flashed a ROM in a few days. But I Rooted a friend of mines yesterday and flashed Suave Smush. Everything was fine until he called me this morning and said he had lost 3G. A little later it would not send or receive a text message. Then it kept saying he was out of his home network. We wipped it clean and did the Nand Restore and its fine now. His phone still has Android 1.5.

View 2 Replies View RelatedI have a terrible bug in my widget. The widget is waken up using an AlarmManager (the update interval is chosen by users, ranging from 30 mins to 2 hours) to grab some data from the Internet and display it on the widget. I do not hold a wakelock since if the phone sleeps, just let it sleeps. There's no way to update the information since nobody will see it. If I put the phone in the basement (has no wi-fi or cell signal) for about an hour. the phone will definitely not update anything. However, when I get it back from the basement, the cell network could never be recovered again no matter how long I have waited (it just get an X on the cell signal icon on the notification bar) that I must restart the phone. May I know if a partial wake lock must be held on checking network availability?

I have a small issue with my remote connectivity to my android, the scenario is simple and my target is to connect to my android remotely through my laptop while the android is connected to my PC in the other room through USB cable, so what I have done already is that am connecting the Android to the PC through a USB cable and the PC to the Laptop through the LAN, now am connecting Remote desktop from my laptop to the PC and on the PC I installed application that can connect to the android so I can totally see the skin of my android and control it, but the final thing I wish to do is to make a phone call, here I connect a Bluetooth to the PC and I connect the Bluetooth as free handset to the android it didn't totally work, you see its interesting scenario and if we work together we can accomplish something really assume
View 1 Replies View RelatedI am looking at which HTC phone to buy. I need WiFi to connect to the Internet at home. I also want PUSH email, my understand of PUSH email is that every half n hour or something I can get the software to go out and search for new emails whilst not having to go into the app and click refresh to see new emails, something which I have to do on my N95. I also need a decent SatNAV, now I know that google navigation is out. I don't know how good it is due to the lack of information out on the Internet. Do all HTC phones drain the battery with GPS? Okay so I need SatNAV, then I also need a phone with decent car cradles, I need something that enables me to rotation it portrait and landscape easily.
Do HTC phones come with a car charger in the box? I also use Gmail a lot, now is there any advantages that I will get from getting a HTC phone and utilizing my Gmail account, as well as calendar. Is there a simple way of getting the phone to sync with outlook such as the tasks and notes you make? Are most applications on Android free? Do the phones last a long time? I like the idea of the kickstand in the Droid incredible I think, that phone is very appealing for me. I am just thinking of getting the phone not for phone and text use but for just Internet and applications.
I have a Service/AlarmManager set to go off ever hour; as seen at: http://github.com/commonsguy/cw-advandroid/tree/master/SystemServices...
The Alarm triggers a Socket connection to communicate with a Web Server. I'm logging the interaction to a file so I can see it later. When I leave the phone on my desk for a day, it seems that more often than not I get a "Network unreachable" error when trying to do any networking.
I believe it is related to how deeply the phone goes into sleep. Is there a special kind of lock I have to hold, or some command required to prep the wireless radio so that it can be ready to access the Internet?
