Eu implementei o Twitter no meu aplicativo, estou enfrentando problemas no retorno de chamada.

s APIs do Twitter foram atualizadas recentemente, por isso não consigo enviar o URL de retorno de chamad

Também a página de configuração agora muda, não há opção para selecionar aplicativos baseados na Web ou aplicativos de área de trabalh

Se eu enviar retorno de chamada nesta linha:

authUrl = provider.retrieveRequestToken(consumer,CALLBACK_URL);

Sempre retorna

oauth.signpost.exception.OAuthNotAuthorizedException: Authorization failed (server replied with a 401). This can happen if the consumer key was not correct or the signatures did not match.

mas se eu enviar comoNul neste seuRedirecionando para a página de login do Twitter, mas após a Autorização bem-sucedida, ela não retorna ao meu Aplicativo.

Depois que o número do PIN for exibido, desejo redirecionar novamente para o meu aplicativ

ota: o Twitter atualizou sua API para que os códigos antigos disponíveis no Post não funcione

Tentei todos os links a seguir

My Code é o seguinte:
