/* i have developed an android application which connects to server for login purpose. For connection i have used ksoap2 library. Intracollege webservice is stored on server. The application works fine when connected to server using wifi. if it is not connected to wifi it displays message "application is crashed" and then application stops working.
I only want to display a simple message "Application is not connected to server" if it is not connected to server using wifi.*/
Try this........
public boolean isNet()
{
boolean status=false;
String line;
try
{
URL url = new URL("http://www.google.com");
BufferedReader reader = new BufferedReader(new InputStreamReader(url.openStream()));
while(( line = reader.readLine()) != null)
{
}
status=true;
}
catch (IOException ex)
{
System.out.println("ex in isNet : "+ex.toString());
if(ex.toString().equals("java.net.UnknownHostException: www.google.com"))
status=false;
}
catch(Exception e)
{
}
return status;
}
if(status==true)
{
//Do your operation
}
else
show("No Internet Connection.");
When status is true do your login process.Otherwise show message "Application is not connected to server".
To check for the internet connection try this out
private boolean haveNetworkConnection() {
boolean haveConnectedWifi = false;
boolean haveConnectedMobile = false;
ConnectivityManager cm = (ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE);
NetworkInfo[] netInfo = cm.getAllNetworkInfo();
for (NetworkInfo ni : netInfo) {
if (ni.getTypeName().equalsIgnoreCase("WIFI"))
if (ni.isConnected())
haveConnectedWifi = true;
if (ni.getTypeName().equalsIgnoreCase("MOBILE"))
if (ni.isConnected())
haveConnectedMobile = true;
}
return haveConnectedWifi || haveConnectedMobile;
}
Check this code, this will help you :
Initialize in the class where you want to check network availability.
OtherUtils otherUtils = new OtherUtils();
if (!otherUtils.isNetworkAvailable(getApplicationContext())) {
Toast.makeText(getApplicationContext(), "No Network Available", Toast.LENGTH_LONG).show();
return;
}
Add below class:
public class OtherUtils{
Context context;
public boolean isNetworkAvailable(Context context) {
this.context = context;
ConnectivityManager connectivity = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);
if (connectivity == null) {
// boitealerte(this.getString(R.string.alertNoNetwork),"getSystemService rend null");
} else {
NetworkInfo[] info = connectivity.getAllNetworkInfo();
if (info != null) {
for (int i = 0; i < info.length; i++) {
if (info[i].getState() == NetworkInfo.State.CONNECTED) {
return true;
}
}
}
}
return false;
}
}
This will surely help you.

I have two TextView, two EditText and two Buttons. I want to set a DialogBox or Toast when the button is clicked without entering any values in the textview. I have two stings, s and s1.

Change your validation to this :
if((s.equals("")) && (s1.equals("")))
{
Toast.makeText(getBaseContext(),"cnt b empty" ,Toast.LENGTH_SHORT).show();
}
Or you can check like this:
if((s.length() == 0) && (s1.length() == 0))
{
Toast.makeText(getBaseContext(),"cnt b empty" ,Toast.LENGTH_SHORT). show();
}

Try if (s.isEmpty() || s1.isEmpty()) to check if your strings are empty. == and .equals will not work with string comparison because they are comparing the objects and not solely the contents. To check if two strings are equal, you can use firstString.compareTo(anotherString) == 0.
Trim your edittext value then compare
if((("").equals(s.trim())) && (("").equals(s1.trim())))

this all of my code.
You don't show where you create your handler (onCreate ? onStart ? somewhere else ?). Is it started from the main thread ? If so, you need to be provide a more complete stack trace so we can understand.
If you're starting it from another thread then that's the issue because it's attempting to change progressDialog and that must be done from the main thread.
PS: if you used an AsyncTask you wouldn't have to scratch your head around this as it's designed to do exactly what you want and be thread safe.
Post comment : use an AsyncThread : add the progress bar in onPreExecute(), change run() to doInBackground() and move the dismiss() to onPostExecute(
I am developing an application to receive data on an Android device from an Arduino. It displays values only up to 255 when I convert it to integer, but I want those values which are sent by the Arduino board. I have tried converting them to strings but that didn't work either.

It looks like the problem is in the Arduino sketch. The msg array contains (unsigned) bytes which have a maximum value of 255.
The line:
msg[1] = value/10
implicitly truncates value/10 (which is an integer between 0 and 1023 - see http://arduino.cc/en/Reference/analogRead) to a maximum of 255.
To send value/10 you'll need to split it over 2 bytes. For example:
msg[1] = (uint8_t) (i & 0xFF);
msg[2] = (uint8_t) ((i >> 8) & 0xFF);
And msg will have to be one byte longer to accomodate.
On the Android (Java) side you'll need to do something like:
int value = (int) buffer[0];
// ...
int tds = buffer[1] + (buffer[2] << 8);
m.obj = new ValueMsg('f', value, ret, tds,
buffer[3], buffer[4], buffer[5], buffer[6]);
which will require a change to the definition of ValueMsg to accomodate.
Also, there may be a problem with the calls to SndData (assuming the library being used here is the USB_Host_Shield_2.0) as they always send 6 bytes even though in the first time through loop all 6 bytes of msg won't have been initialized.
