cannot use OkHttpClient In the right way

Question

I've tried to use okHttpClient command to send request with URL.

but i noticed a mistake that came to me and prevented me from showing the results. Look at the code and logcat output , and try to help me make some code adjustments. the log c

public class MainActivity extends AppCompatActivity {
        @Override
        protected void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.activity_main);
            Object trace = getHttpResponse();
            Log.i("don_99", "" + trace);
        }



        public Object getHttpResponse() {
            OkHttpClient httpClient = new OkHttpClient();

            String url = "http://www.zoftino.com/api/storeOffers";
            Request request = new Request.Builder()
                    .url(url)
                    .build();
          com.squareup.okhttp.Response response = null;

            try {
                response = httpClient.newCall(request).execute();
                return response.body().toString();
            } catch (IOException e) {
                Log.e(TAG, "error in getting response get request okhttp");
            }
            return null;
        }
}

and here is error in logcat:

The exception tells you what the problem is: `android.os.NetworkOnMainThreadException`. You cannot make requests on the main thread. Create a new thread or task with all the networking logic and use your HTTP client there. — QBrute, Jan 18 '20 at 09:29
Try this :- new Thread( new Runnable() { @Override public void run() { Object trace = getHttpResponse(); Log.i("don_99", "" + trace); } } ).start(); — Sabinmon ks, Jan 18 '20 at 09:36
