MainActivity.javapackage com.icecream.openweather; import android.os.Bundle; import android.widget.TextView; import androidx.appcompat.app.AppCompatActivity; import com.android.volley.Request; import com.android.volley.RequestQueue; import com.android.volley.Response; import com.android.volley.VolleyError; import com.android.volley.toolbox.JsonObjectRequest; import com.android.volley.toolbox.Volley; import org.json.JSONArray; import org.json.JSONException; import org.json.JSONObject; import java.text.SimpleDateFormat; import java.util.Calendar; public class MainActivity extends AppCompatActivity { TextView t1_temp,t2_city,t3_description,t4_date; &#64;Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); t1_temp &#61; (TextView)findViewById(R.id.textView); t2_city &#61; (TextView)findViewById(R.id.textView3); t3_description &#61; (TextView)findViewById(R.id.textView4); t4_date &#61; (TextView)findViewById(R.id.textView2); find_weather(); //이부분 주석처리 시 앱 실행은 됨. } public void find_weather() { String url &#61;&#34;http://api.openweathermap.org/data/2.5/weather?q&#61;islamabad,pakistan&appid&#61;f944fc8bd60081dc2d83b0aeeb82f292&units&#61;Imperial&#34;; JsonObjectRequest jor &#61; new JsonObjectRequest(Request.Method.GET, url, (String)null, new Response.Listener<JSONObject>() { &#64;Override public void onResponse(JSONObject response) { try { JSONObject main_object &#61; response.getJSONObject(&#34;main&#34;); JSONArray array &#61; response.getJSONArray(&#34;weather&#34;); JSONObject object &#61; array.getJSONObject(0); String temp &#61; String.valueOf(main_object.getDouble(&#34;temp&#34;)); String description &#61; object.getString(&#34;description&#34;); String city &#61; response.getString(&#34;name&#34;); // t1_temp.setText(temp); t2_city.setText(city); t3_description.setText(description); Calendar calendar &#61; Calendar.getInstance(); SimpleDateFormat sdf &#61; new SimpleDateFormat(&#34;EEEE&#61;MM-dd&#34;); String formatted_date &#61; sdf.format(calendar.getTime()); t4_date.setText(formatted_date); double temp_int &#61; Double.parseDouble(temp); double centi &#61; (temp_int - 32) /1.8000; centi &#61; Math.round(centi); int i &#61; (int)centi; t1_temp.setText(String.valueOf(i)); }catch(JSONException e) { e.printStackTrace(); } } }, new Response.ErrorListener() { &#64;Override public void onErrorResponse(VolleyError error) { } } ); RequestQueue queue &#61; Volley.newRequestQueue(this); queue.add(jor); } } 앱을 실행하면 강제종료가 되는데(앱이 죽음).., find_weather();를 주석처리했을 때는 실행은 가능합니다.find_weather함수에 문제가 있는 것 같은데,어느 부분을 고치면 될지 알려주시면 감사하겠습니다. Manifest에 android:usesCleartextTraffic&#61;&#34;true&#34;를 추가하여 해결하였습니다.
