I'm writing an application for android. My problem is that I want it to force the connection in GPRS and not use wi fi. I have a solution like below, but this causes the crash of the application at start.
CODE:..............
I also added the below setting lines into manifest file.
CODE:................
Does anyone know the problem, or an answer to set connection type?

In my application I need sometimes send data via http (using HttpClient, HttpGet and HttpPost). Can I choose (from source code) connection which is used? For example, I'd like to use only gprs, not wifi, not bluetooth. Or only wifi, not gprs.

I want to use my Android over 3G for emails and calendar sync. Everything else through WiFi because I am constantly connected to WiFi through my campus/home/work. Only need email on the go.
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.
Does anyone have any app that comes to mind?
How can we know the current connection type (ex. Wifi, 3G, 2G...) programmatically?

I am trying to to use WiFi API to set priorities to created profiles. I am using the priority field of WifiConfiguration to set this information. I have found out that no matter what priority I set, Android always tries to re-connect to the latest access point that it was connected to. Here is what I do: 1) I create a profile A with a very low priority (0) 2) I create a profile B with high priority (100) 3) I connect to profile A 4) I turn Wi-Fi off 5) I turn Wi-Fi back on 6) In the scan Android sees both A & B 7) Android connects to A, even though its priority is much lower. Does anyone has a work around for this?

I did some search in this forum, and found the below thread. So an intent-filter is needed. But it did not have an answer regarding how/ where to add code, and get the file name passed by another app, say a file manager. http://groups.google.com/group/android-developers/browse_thread/threa.
View 8 Replies View RelatedI use my file explorer a lot. It eliminates much of the "You have to put the files here" sort of requirement of many applications. And in many case - movie files for example - when you touch the file, it opens it in the appropriate application. There are exceptions like *.epub files. When I touch one, I get the famous "...does not support." message. So the question is, can I "register" Laputa (for example) to be the app to open *.epub files - Similar to the File Types dialog in Windows?I suppose this might require root access?

View 11 Replies View RelatedThe built-in barcode scanner application on Android (based, I think, on zxing) reads QR Codes and launches that data into an application based on the leading text. For example, "BEGIN:VCAL" might launch a calendar application; "http:" might launch a browser.How can I "register" my application so the OS (or the Barcode application) will call it for a specific type (i.e. leading characters) of QR Code text?
View 2 Replies View RelatedI want to register my application for files of a certain popular and well-documented MIME-type. The problem is that Android does not seem to recognize this MIME-type. The following sample code demonstrates this:

public class HelloAndroid extends Activity { /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); TextView tv = new TextView(this); tv.setText("Hello, Android"); setContentView(tv); String extn = android.webkit.MimeTypeMap.getFileExtensionFromUrl("/data/a.xyz"); String xyzMimeType = android.webkit.MimeTypeMap.getSingleton().getMimeTypeFromExtension (extn); Log.d ("HelloAndroid", "extn: " + extn + " | xyzMimeType: " + xyzMimeType); }

View 2 Replies View RelatedI'm looking for an app that sets specific actions (like changing ringtones, volume of notifications, e-mail notifies on/off) according to the SSID/availability of WiFi networks nearby. Pretty much like "locale" does for position, but tied to WiFi availability.

I can apply the style to a single element in the xml by setting the style element like this:

So, that works, and I notice that change. But what I really want to do is use the style above to apply to my entire application. I thought I'd be able to use this line:
this.getApplicationContext().setTheme(R.style.BlueOnWhite);
Before the super.onCreate of the first activity. But it doesn't work. Should it?
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 ?
