How to Get the content from a HttpResponse (or any InputStream) as a String in android?

This snippet reads all of the InputStream into a String. Useful for any kind of InputStream, including the content of aHttpResponse after a HttpClient request. See also this answer on SO. Essentially StringBuilder is a lot faster, and can be converted to a normal String with the .toString() method.

For reading the content of a HttpResponse use inputStreamToString(response.getEntity().getContent()).

// Fast Implementation

private StringBuilder inputStreamToString(InputStream is) {

    String line = "";

    StringBuilder total = new StringBuilder();

    

    // Wrap a BufferedReader around the InputStream

    BufferedReader rd = new BufferedReader(new InputStreamReader(is));

    // Read response until the end

    while ((line = rd.readLine()) != null) { 

        total.append(line); 

    }

    

    // Return full string

    return total;

}

// Slow Implementation

private String inputStreamToString(InputStream is) {

    String s = "";

    String line = "";

    

    // Wrap a BufferedReader around the InputStream

    BufferedReader rd = new BufferedReader(new InputStreamReader(is));

    

    // Read response until the end

    while ((line = rd.readLine()) != null) { s += line; }

    

    // Return full string

    return s;

}
