Answer 1

I worked on few things and finally found answer myself to my question. Hence posting here.

Issue: No authentication challenges found

Reason : I was not sending AccessToken and AccessTokenSecret in configuration after Login. Hence it was not getting the authentication data.

Solution :

Step 1: I use App-only authentication (without loging into twitter) to fetch the public feeds from twitter. I fetch them successfully. For this I use BearerToken in configuration as follows:

   ConfigurationBuilder configurationBuilder = new ConfigurationBuilder();
   configurationBuilder.setOAuthConsumerKey(Constants.TWITTER_CONSUMER_KEY);
   configurationBuilder.setOAuthConsumerSecret(Constants.TWITTER_CONSUMER_SECRET);
   configurationBuilder.setUseSSL(true);
   // IMPORTANT: set T4J to use App-only authentication
   configurationBuilder.setApplicationOnlyAuthEnabled(true);
   configurationBuilder.setOAuth2TokenType(getOAuth2Token().getTokenType());
   configurationBuilder.setOAuth2AccessToken(getOAuth2Token().getAccessToken());

Step 2: When I try to reply or retweet or mark it as favorite, I check if user is already logged in or not, if it is not logged-in then I try to login first and then do the reply or retweet. For this I use following configuration.

ConfigurationBuilder configurationBuilder = new ConfigurationBuilder();
configurationBuilder.setOAuthConsumerKey(Constants.TWITTER_CONSUMER_KEY);
configurationBuilder.setOAuthConsumerSecret(Constants.TWITTER_CONSUMER_SECRET);

This will give me RequestToken which in turn will give me the AccessToken and AccessTokenSecret.

Step 3 : Thereafter I use following configuration for subsequent requests without any problem.

ConfigurationBuilder configurationBuilder = new ConfigurationBuilder();
configurationBuilder.setOAuthConsumerKey(Constants.TWITTER_CONSUMER_KEY);
configurationBuilder.setOAuthConsumerSecret(Constants.TWITTER_CONSUMER_SECRET);
configurationBuilder.setOAuthAccessToken(getAccessToken()); // from sharedPreferences
configurationBuilder.setOAuthAccessTokenSecret(getAccessTokenSecret()); // from sharedPreferences
