           // Log.i(TAG, "Result Celsius: " + resultString);
        }
        catch(Exception ex) {
            tvData1.setText(ex.toString()+"  Or enter number is not Available!");  
        }

        tvData1 = (TextView)findViewById(R.id.textView1);
    }
}

I am a newbie in android, and I'm trying to communicate .net code using web service. I have tried so many solutions, but I'm getting an error in

httpTransport.call(SOAP_ACTION, envelope); 

I would appreciate any help in resolving this, as I haven't been able to figure it out.

Add the below line :

   setContentView(R.layout.activity_main);
    if (android.os.Build.VERSION.SDK_INT > 9)
    {
         StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build();
         StrictMode.setThreadPolicy(policy);
    }

under setContentView(R.layout.activity_main);

and for ssl Exception you can try:

public Client hostIgnoringClient() {
    try
    {
        SSLContext sslcontext = SSLContext.getInstance( "TLS" );
        sslcontext.init( null, null, null );
        DefaultClientConfig config = new DefaultClientConfig();
        Map<String, Object> properties = config.getProperties();
        HTTPSProperties httpsProperties = new HTTPSProperties(
                new HostnameVerifier()
                {
                    @Override
                    public boolean verify( String s, SSLSession sslSession )
                    {
                        return true;
                    }
                }, sslcontext
        );
        properties.put( HTTPSProperties.PROPERTY_HTTPS_PROPERTIES, httpsProperties );
        config.getClasses().add( JacksonJsonProvider.class );
        return Client.create( config );
    }
    catch ( KeyManagementException | NoSuchAlgorithmException e )
    {
        throw new RuntimeException( e );
    }
}
