Question

How do you do write an HttpPut request with authentication on Android?

(I’m trying to work around using HttpURLConnection, which seems to serious have bugs (at least in Android 2.2) but GET works fine. I’d like to send a JSON representation of an array, and I have correct credentials already set using PasswordAuthentication.)

Here’s one general solution.

HttpParams httpParameters = new BasicHttpParams();
HttpConnectionParams.setConnectionTimeout(httpParameters, this.CONNECT_TIMEOUT);
HttpConnectionParams.setSoTimeout(httpParameters, this.CONNECT_TIMEOUT);

DefaultHttpClient client = new DefaultHttpClient(httpParameters);

// Retrieve user credentials.
SharedPreferences settings = context.getSharedPreferences("LOGIN", 0);
String loginNameString = settings.getString("login_name", null);
String passwordString = settings.getString("password", null);

UsernamePasswordCredentials credentials = 
             new UsernamePasswordCredentials(loginNameString, passwordString);
AuthScope authScope = new AuthScope(AuthScope.ANY_HOST, AuthScope.ANY_PORT);
             client.getCredentialsProvider().setCredentials(authScope, 
                                                              credentials);

HttpPut put = new HttpPut(UPLOAD_URL);

try
{
    put.setEntity(new StringEntity(responseJSONArray.toString(),    
                       SERVER_PREFERRED_ENCODING));
    put.addHeader("Content-Type", "application/json");
    put.addHeader("Accept", "application/json");
    HttpResponse response = client.execute(put);

    // 200 type response.
    if (response.getStatusLine().getStatusCode() >= HttpStatus.SC_OK &&
    response.getStatusLine().getStatusCode() < HttpStatus.SC_MULTIPLE_CHOICES)
    {
      // Handle OK response etc........
    }
}
catch (Exception e)
{
}
