Android :: Data Connectivity Problem .Server Failed To Communicate
Jan 17, 2010
Can any body tell me why this is happening..Whenever i try to open a website located in the intranet server,(or even a local machine with tomcat web server) i get this message.Data connectivity problem..Server failed to communicate.Please try again later The browser works fine for all other websites i tried google,youtube,yahoo,etc all of them worked fine.Do i need to set any other value in the emulator? Any one else got the same problem?
Has anybody received an error "the server failed to communicate" when attempting to get an internet connection?A restart didn't appear to resolve it so I took the battery out and now its working.I don't think its network related as I had a HSDPA signal at the time.
I'm starting my first Android Application and I'm trying to figure out the best way to implement an RPC layer to communicate with my Tomcat server. Basically, I've got POJOs on the Android Client and on the Server. I simply would like to seserialize the POJOs on Android, send up an HTTP Post, deserialize on the server, do some work, then serialize a POJO response back down to the client. I've seen a number of posts referencing JSON and XML but nothing really definitive.
Further clouding the matter is the different Android SDKs out there that seem to have different levels of support for each. Obviously, if Android has a native library that works well, I'd like to use that. Additionally, I'd like something that could work with my existing POJOs without a great deal of trouble. What are the best practices for this sort of thing? Can anyone send me to any tutorials that have some solid examples on how to get this implemented and going?
I have recently created a new gmail account, and transferred all contacts etc. Since my Hero cannot read more than one account, I deleted my first account - planning to reconnect my Hero to the new account - thus enabling all the new data to connect.
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?
I have recently upgraded my HTC Desire on O2 to Android 2.2. Since then, I've intermittently been having issues going on the internet on my phone. Much of the time it's fine, but then it'll have a couple of hours of refusing any kind of data connection - it won't browse or sync Twitter/Facebook etc.I've tried rebooting, and disabling/reenabling Mobile Internet, to no avail. Does anyone have any thoughts?
I was wondering how I can create a variable for whether or not my phone has data connectivity. I use google voice for texting (I have a sprint integrated google voice number), but when I go out I turn off my wifi/3g to save battery, and text with my stock SMS app. When I swipe upwards on my launcher (Nova launcher), my texting app launches (google voice). However, I would like that gesture to launch a Tasker task - one that launches Google Voice if my phone has data connectivity, or the stock SMS app if my phone does not have data connectivity. However, Tasker does not have a built in variable for data.
More specifically, I would like this task to do the following (in pseudocode)
if (%data == ON) Launch Google Voice else Launch stock SMS app
I bought a used working EVO. I activated it and I noticed that when I turn it on, The data connection does not start. When I go into Settings/Wireless & networks, the Monile Network says Connection failed. If I turn it off and back on, it connects fine. Is there a setting that I am missing that is causing this problem? I rooted it before activating so I don't know if I should take it back to stock. But I would prefer not to.
In my application, I need to record some file. I want to send audio data to server while recording. Do you know how to do that? After user stop saying, I need to detect the end of speaking. Is there any algorithm to do that? I want my application similar as google voice search,
I write a app that'd store local data on phone as well as online, and users can modify the data on their phones with a Android client and modify the remote data stored in a server through a browser interface. The assumption is that the app would need to work offline and sync. when it's online.
One example is that you have address book data on a server and a android client.
what's the best way to keep the data synchronized and detect conflicts?
In my application I am sending data to server if I had not pressed back button when data is sending to server then data is successfully saved on server and new screen (one created in layout folder) is displayed which says data is stored. But at the time of sending data if i pressed back button then also data successfully saved on server but I can't see that new screen that data is stored on server. How to handle this situation?

I'm using ksoap over https to request data from a server. It works fine, but only every other time! Looking at the traffic with wire shark it seems that on every other request something goes wrong with the ssl traffic/handshake (data doesn't even get sent except for an fc-fault coming back). Doing the same requests using curl the server always responds fine and afaik the iPhone version of the program also doesn't seem to have any problems with the server.
I working on the app where I get the data from the server using rest call and add it to the view. I get all the initial data correctly. I use AsyncTask for doing it. Now I want to periodically (say 2 mins) fetch the new data from the server and add it to view.Periodically fetching data (polling) from the server in Android.

I have an application where it displays a list of items in ListView. These items(strings) are coming from the server which are stored in English language. I want to display these English characters in Chinese language in my application. Is it default if the user selects Chinese Lang for their device or should i have to do something else.. I know how to localize images, strings that are stored in resources, but i want to localize the strings coming from internet that are stored in a single language in database.
EDIT: If the administrator enters the data to the database in chinese language, will it be displayed in Chinese in my ListView?
