Do you know how to set Content-Type on HttpURLConnection? Following code is on Blackberry and I want the Android equivalent:
connection.setRequestProperty("content-type", "text/plain; charset=utf-8");
connection.setRequestProperty("Host", "192.168.1.36");
connection.setRequestProperty("Expect", "100-continue").

I need to send asynchronous calls to the server. During network connection this works fine. How ever if i disable my LAN from Network connections android will through a socket exception after the specified timeout for that particular call. Now the issue that i face is the time out happens in a synchronous manner. Though both the calls has been started in a thread the timeout is not happening at the same time. If i keep the timeout as 20sec i am getting a socket exception for the first call after 20 sec and after the next 20 sec i get the timeout for the next call. Why is this happening..? I am not opening two connections asynchronously in this case. I am attaching a sample code that can replicate the above scenario. Code...
View 9 Replies View RelatedI'm making an http request. I'm on a platform (android) where network operations often fail because the network connection might not be immediately available. Therefore I'd like to try the same connection N times before completely failing. Was thinking of something like this:
DefaultHttpClient mHttp = ...;
public HttpResponse runHttpRequest(HttpRequestBase httpRequest)
throws IOException
IOException last = null;
for (int attempt = 0; attempt < 3; attempt++) {
try {
HttpResponse response = mHttpClient.execute(httpRequest);
int statusCode = response.getStatusLine().getStatusCode();
if (statusCode == 200) {
return response }
} catch (IOException e) {
httpRequest.abort();
last = e;
throw last;
I'm mostly worried about the connection being in some state which is invalid on subsequent retries. In other words, do I need to completely recreate 'httpRequest', should I avoid calling httpRequest.abort() in the catch block, and only call it in the final failure?

View 2 Replies View RelatedI'm facing an annoying problem here. My application is connected to a server that sends some data from time to time. It's some kind of eventing server. In order to receive data, I'm connecting to the server with an HttpURLConnection, retrieve the response InputStream and loop on it with the read method. The connection is always open. The distant server is cutting the connection every 5 minutes (for test purpose). When connection is closed, my application has to reconnect again. We detect a Connection Reset by Peer exception when the server closes the connection. The problem is that most of the time, I never receive the Connection Reset by Peer exception. So my application can't know that is has to reconnect and it's stucked on the read instruction. The InputStream.Read() method shouldn't always raise an exception if the connection is closed? What can I do to always detect Connection Reset by Peer exception?

Is there a program that can control what type of data other apps use?
For instance:
Email: 3G (WiFi Preferred)
Calendar Sync: 3G (WiFi Preferred)
Contact Sync: 3G (WiFi Preferred)
Browser: WiFi Only
YouTube: Wifi Only
Or along these lines.

So I used my phone as a storage-device connecting it to my computer via USB earlier today, and just now I notice that I can't browse my photos or music. It says:
"Your content is unavailable because your phone is being used as USB storage. Disconnect USB to access your content."
Before unplugging the phone earlier, I rightclicked the little icon at the bottom-right of my computer screen and chose "disconnect storage device", after which I received notification that it was then safe to remove the device. Is there something more I should be doing, a similar setting in the phone? Or did it just bug and I need a reboot?
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 ?
This may seem like a stupid question but I need to be sure. I was wondering if it was possible to pro-grammatically change the Content Provider used when making a query given a Content URI. The reason being I need to know if it's possible to force the Calendar/Contacts applications to read from a different database via a different Content Provider temporarily while my application is running, so that I can reuse those applications to display my own data. Since the Content URI s are hard coded in each of these applications the only way it might be possible is if we could somehow temporarily change the Content Provider used for a given URI. I know this probably isn't possible, I just need to show it isn't. Could someone confirm this can't be done?

View 1 Replies View RelatedMy current situation is that I have a phone with 2 camera apps on it, stock and camera FV-5.
Camera FV-5 is slower than the stock camera, so I only use it in situations which I need manual control.
Whenever I open whatsapp and try to send a photo, the app asks me which camera I want to use, with no option to always use stock. I don't want camera FV-5 to exist as an option, as I will open it if I want to use it.
Is there a way to remove an app from the list so that my phone does not recognise camera FV-5 as a camera?
