Android Twitter sendDirectMessages not working

Question

I am trying to send the Direct messages from my Android app. For that I have Googled and found the following solution from the links . In that Twitter4j I have found the code snippet. I have tried the same in my Android app also, but got the issue:

http://twitter4j.org/en/code-examples.html

// The factory instance is re-useable and thread safe.
    Twitter sender = new TwitterFactory().getInstance();
    DirectMessage message = sender.sendDirectMessage(recipientId, message);
    System.out.println("Sent: " message.getText() + " to @" + message.getRecipientScreenName());


Issue :
**10-10 20:04:26.440: E/AndroidRuntime(6935): java.lang.IllegalStateException: Authentication credentials are missing. See http://twitter4j.org/configuration.html for the detail.**

Please help me to come out of this issue.

Answer 1

The error message says:

Authentication credentials are missing.

From the Twitter4J Code Examples page:

To run the example codes, you need to have OAuth credentials configured in twitter4j.properties. See Twitter4J - Configuration for the detail.

You can't send direct messages on Twitter unless you're logged in (unlike some other features, like reading a random user's status updates). You'll need to configure your authentication credentials by one of the three methods given on the Twitter4J Configuration page before the code example will work.
