I have a service that when accessed by the browser it shows the xml through the " link command. p>

I made a test application to test the connection and when it arrives at the command Tranport.call(SOAP_ACTION, envelope) the error log is displaying error messages related to the transport. Error Below:

Good practices recommend using a class that inherits from an AsyncTask for network tasks. By doing this the requests will be performed on a separate Thread which then updates its UI Thread (Screen / Activity).

Based on your first error line: android.os.NetworkOnMainThreadException .

It may be noted that it is an android system error due to network usage on the main Thread.

This video explains well how an AsyncTask works.

If you do not resolve it, you should also review the composition of your SOAP request, noting that everything is in accordance with your WSDL.

As pointed out by @FeedProject, you can not call the WebService in Thread Principal.

But if for some reason you do not want to use AsyncTask , such as having greater control over the threads, you can use HandlerThread and emulate a AsyncTask .

The code below assumes that type X will be the data input and type Y the output.

public abstract class AsyncRunnable<X, Z> implements Runnable {

    private static HandlerThread handlerThread;
    private Handler handler;
    protected X[] parametros;
    protected CountDownLatch latch;
    protected Z retorno;

    public void run() {

    }

    protected AsyncRunnable() {
        if (AsyncRunnable.handlerThread == null) {
            AsyncRunnable.handlerThread =  new HandlerThread("WebServiceThread", android.os.Process.THREAD_PRIORITY_BACKGROUND);
            AsyncRunnable.handlerThread.start();
        }
        this.handler = new Handler(AsyncRunnable.handlerThread.getLooper());
    }

    public AsyncRunnable execute(X... parametros) {
        this.parametros = parametros;
        this.latch = new CountDownLatch(1);

        this.handler.post(this);
        return this;
    }

    public Z get() {
        try {
            latch.await();
        } catch (Exception ignore) {

        }
        return this.retorno;
    }
}

If you need to call it:

AsyncRunnable<Object, Object> asyncRunnable = new AsyncRunnable<Object, Object>() {
    @Override
    public void run() {
        super.run();
        this.retorno = webServiceClient.CallMethod(this.parametros[0], this.parametros[1]);
    }
};

Object[] input = new Object[] { new Object(), new Object() };
Object output = asyncRunnable.execute(input).get();

The only difference from the above code for AsyncTask is that all calls to the WebService will be performed by the same Thread .

Remembering that this is only an alternative to AsyncTask .
