Is there a way for Twitter4J to verify credentials by only using consumer key and secret?

I'm working on an Android App which allows users to configure Twitter consumer key and secret by themselves (Access Token and Access Token Secret are not configured). I want to verify key and secret like below before showing login page, but it throws an exception:

Twitter twitter = new TwitterFactory().getInstance();
twitter.setOAuthConsumer(key, secret);
        try {
            User user = twitter.verifyCredentials(); // this line throws an exception
        } catch (Exception e) {
            e.printStackTrace();
        }

The exception is:

Twitter credential verification fails.java.lang.IllegalStateException: Authentication credentials are missing. See http://twitter4j.org/en/configuration.html for details

Is there a way to verify the consumer Key and Secret without Access Token and Access Token Access?

The exception message that you encounter is pretty clear:

Authentication credentials are missing.

You need to authenticate correctly first, before trying to access the Twitter API programmatically. Using only setOAuthConsumer(key, secret) does not set/configure necessary access token information. Both information needs to be provided (Hint: If you're interested in it, this introduction gives you an overview on how the OAuth authentication works).

According to http://twitter4j.org/en/configuration.html you can then initialize the code via a ConfigurationBuilder instance like so:

ConfigurationBuilder cb = new ConfigurationBuilder();
cb.setDebugEnabled(true)
  .setOAuthConsumerKey("*your-consumer-key*")
  .setOAuthConsumerSecret("*your-consumer-secret*")
  .setOAuthAccessToken("*your-access-token*")
  .setOAuthAccessTokenSecret("*your-access-token-secret*");
TwitterFactory tf = new TwitterFactory(cb.build());
Twitter twitter = tf.getInstance();

Given valid a AccessToken/AccessTokenSecret, you should then be able to call:

try {
    User user = twitter.verifyCredentials(); 
    // ... do further things....
} catch (Exception e) {
        e.printStackTrace();
}

Hope it helps.
