Create a weather app that processes JSON requests The app wi

Create a weather app that processes JSON requests. The app will need to adhere to the following:

-- Allow the user to input a major city in the U.S.

-- Connect to the free Web site: OpenWeatherMap.org to retrieve weather data

-- Create a ListView that displays 10 days of weather data for that city.

Please upload a screenshots that show the weather app working in the emulator. The screenshots need to show that the app and all component parts work. As a minimum, upload the following for your weather app:

Two different screenshots, each showing the results of a different city entered by the user.

Solution

Below is the code that uses the JSON requests that links to the weather website to get the data.

import java.io.BufferedReader;
import java.net.URL;
import java.io.InputStreamReader;
import java.net.HttpURLConnection;
import org.json.JSONObject;
import android.content.Context;
import android.util.Log;

public class FetchData {

private static final String OPEN_WEATHER_MAP_API = \"http://api.openweathermap.org/data/2.5/\";

public static JSONObject getJSON(Context con, String city){
try {
URL link = new URL(String.format(OPEN_WEATHER_MAP_API, city));   
HttpURLConnection con = (HttpURLConnection)link.openConnection();
con.addRequestProperty(\"x-api-key\",con.getString(R.string.open_weather_maps_app_id));
BufferedReader buffer = new BufferedReader(new InputStreamReader(con.getInputStream()));
StringBuffer str = new StringBuffer(1024);
String temp =\"\";
while((temp=buffer.readLine())!=null)
str.append(temp).append(\"\ \");
reader.close();
JSONObject result = new JSONObject(str.toString());
if(result.getInt(\"cod\") != 200){
return null;
}

return result;
}catch(Exception ex){
return null;
}
}   
}
