Getting response with Asynchronous Http Client

Question

Good morning. I want to send get request and show response in TextView.

public class MyHttpClient {

private static final String BASE_URL = "http://pgu.com";

private static AsyncHttpClient client = new AsyncHttpClient();

 public static void get(String url, RequestParams params, AsyncHttpResponseHandler responseHandler) {
      client.get(getAbsoluteUrl(url), params, responseHandler);
 }   
 private static String getAbsoluteUrl(String relativeUrl) {
      return BASE_URL + relativeUrl;
  }}

I'm calling get from this class

public class MyHttpClientUsage {

Handler h;

public MyHttpClientUsage(Handler h){
    this.h = h;
}

public void getInfoAbout() throws HttpException{

    RequestParams params = new RequestParams();
    params.put("a", "Static");
    params.put("content", "47");

    MyHttpClient.get("", params, new AsyncHttpResponseHandler(){
         @Override
            public void onSuccess(String response) {
                  System.out.println(response);
                              //Simplify sending int to TextView
                  MyHttpClientUsage.this.h.sendEmptyMessage(678); 
                         }
    });
}}

In activity I have a Handler to obtain a message and set TextView

public class MainActivity extends Activity {

Handler h;
TextView largeText;

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    largeText = (TextView) findViewById(R.id.textView1);

    h = new Handler(){

        public void handleMessage(android.os.Message msg){
            largeText.setText(msg.what);
        }

    };

    MyHttpClientUsage connect = new MyHttpClientUsage(h);
    try {
        connect.getInfoAbout();
    } catch (HttpException e) {
        e.printStackTrace();
    }

}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    getMenuInflater().inflate(R.menu.activity_main, menu);
    return true;
}}

In LogCat I have this warning

02-06 14:30:51.783: W/dalvikvm(546): threadid=1: thread exiting with uncaught exception (group=0x409961f8)

and error

02-06 14:30:51.833: E/AndroidRuntime(546): android.content.res.Resources$NotFoundException:   String resource ID #0x2a6

The error is telling us that some requested resource was not found. Double-check your xml layouts and clean/rebuild your project. — Sotirios Delimanolis

Thanks, now it's working! I hoped that autoboxing int to Integer and calling toString() are working. — Valeriy

as you can see here Message. what is an int.you are passing int to setText method of TextView which take CharSequence as parameter . change your your code as :

largeText.setText(String.valueOf(msg.what));

OR

largeText.setText(msg.what.toString());
