i have been trying to delete an album from my picasa web album..
however i have tried everything and it isn't working properly..
i am pasting the code here
can anyone please tell me why it is not working properly
also my firewall is blocking the DELETE request so i have used the
alternate method as suggested in this forum
here's the code:
private static final String CLIENT_LOGIN_URL =
"https://www.google.com/accounts/ClientLogin";;
private static final String PICASA_POST_URL_TEMPLATE =
"http://picasaweb.google.com/data/feed/api/user/%s";;
private static final String PICASA_DELETE_URL_TEMPLATE =
"http://picasaweb.google.com/data/entry/api/user/%s";;
private static final String EMAIL = "<email>";
private static final String PASSWORD = "<password>";
private static final String AUTH_PREFIX = "Auth";
private static final String AUTH_HEADER_KEY = "Authorization";
private static final String AUTH_HEADER_VALUE_TEMPLATE = "GoogleLogin
auth=%s";
private static final String GDATA_VERSION_HEADER_KEY = "GData-
Version";
private static final String GDATA_VERSION_HEADER_VALUE = "2";
private static final String CONTENT_TYPE_HEADER_KEY = "Content-Type";
private static final String CONTENT_TYPE_HEADER_VALUE = "application/
atom+xml";
private static final String CONTENT_LENGTH_HEADER_KEY = "Content-
Length";
private static final String MIME_VERSION_HEADER_KEY = "MIME-Version";
private static final String MIME_VERSION_HEADER_VALUE = "1.0";
private static final String USER_AGENT_HEADER_KEY = "User-Agent";
private static final String USER_AGENT_HEADER_VALUE = "Picasa Android
Client";
private static final String X_HTTP_METHOD_OVERRIDE="X-HTTP-Method-
Override";
private static final String X_HTTP_METHOD_OVERRIDE_VALUE = "DELETE";
private static final String IF_MATCH = "If-Match";
private static final String IF_MATCH_VALUE = " *";
private void deleteAlbum(String auth,String albumid)
{
try
{
StringBuffer xmlBuffer = new StringBuffer();
xmlBuffer.append("<entry xmlns='http://www.w3.org/2005/Atom'" +"
xmlns:media='http://search.yahoo.com/mrss/'"+
" xmlns:gphoto='http://schemas.google.com/
photos/2007'>");
xmlBuffer.append("<link rel='edit'"
+"href='http://picasaweb.google.com/data/entry/api/user/userid/
albumid/"+albumid+"'/>");
xmlBuffer.append("</entry>");
URL url = new URL(String.format(PICASA_DELETE_URL_TEMPLATE,
"userid"));
HttpURLConnection httpConnection = (HttpURLConnection)
url.openConnection();
httpConnection.setRequestProperty(
AUTH_HEADER_KEY,
String.format(AUTH_HEADER_VALUE_TEMPLATE, auth));
httpConnection.setRequestProperty(
GDATA_VERSION_HEADER_KEY, GDATA_VERSION_HEADER_VALUE);
httpConnection.setRequestProperty(
CONTENT_TYPE_HEADER_KEY, CONTENT_TYPE_HEADER_VALUE);
httpConnection.setRequestProperty(
CONTENT_LENGTH_HEADER_KEY,
Integer.toString(xmlBuffer.length()));
httpConnection.setRequestProperty(
USER_AGENT_HEADER_KEY, USER_AGENT_HEADER_VALUE);
httpConnection.setRequestProperty(
MIME_VERSION_HEADER_KEY, MIME_VERSION_HEADER_VALUE);
httpConnection.setRequestProperty(
X_HTTP_METHOD_OVERRIDE, X_HTTP_METHOD_OVERRIDE_VALUE);
httpConnection.setRequestProperty(
IF_MATCH, IF_MATCH_VALUE);
httpConnection.setDoOutput(true);
httpConnection.setRequestMethod("POST");
OutputStreamWriter writer = new
OutputStreamWriter(httpConnection.getOutputStream());
System.out.println(xmlBuffer.toString());
writer.write(xmlBuffer.toString());
writer.flush();
int responseCode = httpConnection.getResponseCode();
System.out.println(responseCode);
}catch(Exception e){}
}
this is returning a 501 status code !!!
