How to solve Networkonmainthread Exception

Question

I call a web service of real estate web site and for that i built my own method's and all.. I develop a execute method in which i will set my url as per my requirement as below :

 public void Execute(RequestMethod method) throws Exception
    {
        switch(method) {
            case GET:
            {
                //add parameters
                String combinedParams = "";
                if(!params.isEmpty()){
                    combinedParams += "?";
                    for(NameValuePair p : params)
                    {
                        String paramString = p.getName() + "=" + URLEncoder.encode(p.getValue(),"UTF-8");
                        if(combinedParams.length() > 1)
                        {
                            combinedParams  +=  "&" + paramString;
                        }
                        else
                        {
                            combinedParams += paramString;
                        }
                    }
                }

                HttpGet request = new HttpGet(url + combinedParams);

                //add headers
                for(NameValuePair h : headers)
                {
                    request.addHeader(h.getName(), h.getValue());
                }

                **executeRequest(request, url);** // This throws an exception
                break;
            }
            case POST:
            {
                HttpPost request = new HttpPost(url);

                //add headers
                for(NameValuePair h : headers)
                {
                    request.addHeader(h.getName(), h.getValue());
                }

                if(!params.isEmpty()){
                    request.setEntity(new UrlEncodedFormEntity(params, HTTP.UTF_8));
                }

                executeRequest(request, url);
                break;
            }
        }
    }

In get case , i send the request using httpget with my desired url but at that time network on main thread exception is generated.

in your AndroidManifest you can also use the following to skip the error:

<uses-sdk android:minSdkVersion="8" 
        android:targetSdkVersion="8" />

In my case, I was testing some old apps that another person made and I could not understand why some worked and others didnt, considering that all of them use the same library. This explained the issue. Thanks! – AlvaroSantisteban Mar 12 '14 at 13:49

Change your code to below one i.e call execute this way

new Thread()
{
    @Override
    public void run()
    {
        Execute();
    }
}.start();

You have to use a Thread or AsyncTask, this post explains a lot about this error.
