So I am trying to retrieve JSON object from url. And I cannot retrieve anything from url. So to test why, I tried the same code on Spring application, and it works just fine. It crashes on code below only on android environment. Please help
package com.example.sandbox;
import org.json.JSONException;
import org.json.JSONObject;
import java.io.*;
import java.net.URL;
import java.nio.charset.Charset;
private static String readAll(Reader rd) throws IOException {
StringBuilder sb = new StringBuilder();
int cp;
while ((cp = rd.read()) != -1) {
sb.append((char) cp);
}
return sb.toString();
}
public JSONObject readJsonFromUrl(String url) throws IOException, JSONException {
InputStream is = new URL(url).openStream();
try {
BufferedReader rd = new BufferedReader(new InputStreamReader(is, Charset.forName("UTF-8")));
String jsonText = readAll(rd);
JSONObject json = new JSONObject(jsonText);
return json;
} finally {
is.close();
}
}
}
Please check your internet connection and also check if you have added permission for INTERNET in your app's manifest that might be issue.
what error do you get exactly ?
