Android :: unknown host exception to GAE?


Game :: Android Java.net.Unknown Host Exception

Jul 20, 2010

I have android code that uses a background process to routinely (e.g. hourly) connect to a content source on the web to check for updated content. As new users download the app and run it for the first time, it seems (and this is just a "seems at the moment) that in this first-run situation, because the DNS for our servers are not cached already on the device, those first series of connections fail with dreaded UnknownHostException: Host is unresolved. And of course, the application tries again later and (again, "it seems like") it is all working -- perhaps because the OS has had time to actually resolve the address. So, my question(s) are: (1) Do other Android developers see this behavior with their deployed applications as well? First time, a series of "host unresolved" issues that work themselves out later. (2) Does anyone have a better strategy for "warming up the DNS" so-to-speak so that the first real connections work? or perhaps do you just re-try with some back-off looping when you encounter this exception? I was contemplating having a separate thread that tries to fetch a small text file from our server and have it just loop until it gets it and maybe (not sure about this part) block the other outgoing network connections until it succeeds.

Android :: Unknown Host When Connected In WiFi

Jun 12, 2009

I send files to FTP server in my application. Internet permission is set :
<uses-permission android:name="android.permission.INTERNET"/>
It works quite fine when connected with 3G/3G+. Sometimes, not very often, I get a "SocketException no route to host" or "unknown host" exception when trying to connect. When I'm connected with WIFI, it works sometimes and it's very fast, but the same error occurs very often, and when it has occurred I must restart my WiFi to be able to connect again, even with webbrowser. I use apache commons FTPClient this way:

ftpClient.connect(server, 21); ftpClient.login(user, password);
ftpClient.changeWorkingDirectory(directory); ftpClient.setFileType(FTP.BINARY_FILE_TYPE);
BufferedInputStream buffIn = new BufferedInputStream(new FileInputStream(file));
ftpClient.enterLocalPassiveMode(); ftpClient.storeFile(file.getName(), buffIn); buffIn.close();
ftpClient.logout(); ftpClient.disconnect();

Errors look like this:
06-12 11:17:32.887: ERROR/DictoSyl(3146): No route to host 06-12 11:17:32.887:

or:

It looks like having forgot something that makes connection down after several uses of my ftp program, but what? And why does this work quite well (but not always) with 3G/EDGE connection?

Android :: Widget Host App With Custom View

Mar 11, 2010

I'm writing an app that will host widgets. The app has custom view (which probably is the source of issue).mView.addWidget() basically just remembers this AppWidgetHostView instance and then mView draws it directly onto canvas. Visually everything is fine.I can see the actual widget. But the issue is with reacting on UI events. Please advise what needs to be done in the parent view in order to correctly trigger handlers in the widgets like onClick().I used standard widgets which normally react on click events. None worked.I also created my own test widget with listener and onClick()is successfully triggered if the widget is added on Homescreen, but doesn't work in my app.mView correctly detects click event and I tried to call widget.perform Click there, which returns false meaning onClickListener is not registered in the widget. But according to source .would call updateAppWidget which would register its onClick listener.

Android :: USB Host / Serial Port Access

Sep 2, 2009

I am trying to figure out if there is any way by which I can access any USB device which is connected to my Android phone's USB port and read data off it? For ex. Can I connect a camera to my phone and pull pictures out of it? I know that we need a HOST-DEVICE configuration to be able to do that... have tried doing this on other devices before picking up my android phone.. thought there would be an easier way to get this done. now, when I connect my phone to a digital picture frame, I can see on the phone that it identifies the USB device it is connected to and goes into a USB mass storage mode. What I want to know is if after this, I can read data from the frame or send data to it. I want to write an app that pulls data over USB and stores it into the phone memory.

Android :: Emulator / Host Network Setup Issue

Oct 22, 2010

I am trying to test some udp networking between emulator and host and I have a problem with setup. I assigned address 10.0.2.14 to the host interface with 10.0.2.1 as gateway.. Can't ping 10.0.2.15 from my host, neither can i ping 10.0.2.14 from emulator. Ping from emulator to 10.0.2.2 works fine - I can capture that ICMP traffic on the loop back interface of my host, so ICMP works, but how can i create traffic from the host to emulator? Can someone point me how to make it work? Note: firewall on my host is disabled.

Android :: How Host Machine Connect To Emulator Using Socket

Feb 2, 2009

How can my host machine connect to emulator using socket? In my application, I need emulator to open a server socket, then host machine connects to emulator as a client. But when host creates the socket using "10.0.2.15:xxxxx" (xxxxx is the port which emulator is listenning), it doesn't work. I think maybe the address"10.0.2.15" goes wrong. Is it a local address behind the "virtual router" and the host can't find? If so, how to find a correct IP address of emulator?

Android :: Tab Host - Property In Manifest For Search Activity

Aug 25, 2010

I have a tab host with two tabs. I want one of those tabs to be a search screen. The content for the tab is a ListActivity. I'm pulling the content from a web service. My problem is, when I execute the search a new intent is pushed onto the screen. I've used the android:launchMode="singleTop" property in my manifest for the search activity. What that seems to have done is, once the new intent is pushed on top of the TabActivity, every time I run the search it reuses that intent. But I want the already existing intent which is set as the tab's content to be the one it uses.

Android :: Inter Activity Communication In Tab Host Application

Jul 22, 2009

Here's the deal: I have an Android application that needs to call a web service every X seconds (currently 60 seconds). This application has multiple tabs and these tabs all need to interact with the data themselves. One is a MapView, one is a ListView and then the third is irrelevant but will need to also get some global data eventually. The issue is that I want my main activity to have a thread that runs in the background, gets the results and then instructs both child activities in the TabHost to update themselves with the latest data. Also, when the user clicks on the tabs and the onCreate/onResume activities fire, I would also like to force a redraw by getting the latest data from the main activity. I'm really at a loss here. I've tried this with a service and some ghetto static methods to pass an instance of the Activities to the Service to call specific functions to update their views whenever the timer fired, but the slowdowns were pretty bad and the code was just ugly ugly ugly.

So I implemented it as a timer-driven thread in the tabhost activity and then I have timer-driven threads in each child activity that then grab the data (in a synchronized fashion) and update their map/list. It's much faster but still feels slightly hack-ish, especially the part where I'm calling a custom function in the parent activity like so:
((MainActivity)getParent()).getNearbyMatches();
This adds an element of strong coupling that I'm not entirely thrilled with, but from a performance standpoint it's much better than it was. I appreciate the answers that have already been given and will do a bit of research on the content provider front but I'm not sure I want to go back to the service model.
