Need Help with android studio project

[TeamLTG]

Hello,

 

I have been working on android studio project which uses a REST template. It keeps giving me an AsyncTask Error. It seems like it wont connect to internet.

 

Main

 

package al.programming.erlisciko.avp_workplez;

import android.os.AsyncTask;
import android.provider.Settings;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.util.Log;
import android.widget.TextView;


import org.springframework.core.ParameterizedTypeReference;
import org.springframework.http.HttpEntity;
import org.springframework.http.HttpMethod;
import org.springframework.http.ResponseEntity;
import org.springframework.http.converter.StringHttpMessageConverter;
import org.springframework.web.client.RestTemplate;

import java.util.List;
import java.util.concurrent.ExecutionException;

public class MainActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        String android_id = Settings.Secure.getString(this.getContentResolver(),
                Settings.Secure.ANDROID_ID);
        // The connection URL
        AsyncTask<String, Void, ResponseEntity<Object>> task = new RestTask().execute("https://jsonplaceholder.typicode.com/posts/1");

        Object result = new Object();
        try {
            result = task.get().getBody();
        } catch (InterruptedException e) {
            e.printStackTrace();
        } catch (ExecutionException e) {
            e.printStackTrace();
        }
// Make the HTTP GET request, marshaling the response to a String

        final TextView textview=(TextView) findViewById(R.id.textview);
        final TextView loltext=(TextView) findViewById(R.id.loltext);
        textview.setText(android_id);
        loltext.setText(result.toString());

    }




}

class RestTask extends AsyncTask<String, Void, ResponseEntity<Object>> {


    @Override
    protected ResponseEntity<Object> doInBackground(String... params) {
        RestTemplate restTemplate = new RestTemplate();
        //GET
        String url
                = "https://jsonplaceholder.typicode.com/posts/1";
        HttpEntity<String> entity = new HttpEntity<String>("parameters");

        ResponseEntity<Object> result
                = restTemplate.exchange(url, HttpMethod.GET, entity, Object.class);

        return result;
    }

    @Override
    protected void onPostExecute(ResponseEntity<Object> deviceResponseEntity) {
        Object device = deviceResponseEntity.getBody();
    }
}
