HttpUrlConnection.getInputStream returns empty stream in Android

Question

I make a GET request to a server using HttpUrlConnection. After connecting: - I get response code: 200 - I get response message: OK I get input stream, no exception thrown but: - in a standalone program I get the body of the response, as expected: {"name":"my name","birthday":"01/01/1970","id":"100002215110084"} - in a android activity, the stream is empty (available() == 0), and thus I can't get any text out. Any hint or trail to follow? Thanks. EDIT: here it is the code Please note: I use `import java.net.HttpURLConnection;` This is the standard http Java library. I don't want to use any other external library. In fact I did have problems in android using the library httpclient from apache (some of their anonymous .class can't be used by the apk compiler). Well, the code: ``` URLConnection theConnection; theConnection = new URL("www.example.com?query=value").openConnection(); theConnection.setRequestProperty("Accept-Charset", "UTF-8"); HttpURLConnection httpConn = (HttpURLConnection…

Accepted Answer

Trying the code of Tomislav I've got the answer.

My function streamToString() used .available() to sense if there is any data received, and it returns 0 in Android. Surely, I called it too soon.

If I rather use readLine():

```
class Util {
public static String streamToString(InputStream is) throws IOException {
        StringBuilder sb = new StringBuilder();
        BufferedReader rd = new BufferedReader(new InputStreamReader(is));
        String line;
        while ((line = rd.readLine()) != null) {
            sb.append(line);
        }
        return sb.toString();
    }
}
```

then, it waits for the data to arrive.

Thanks.
