If you're looking for a way to send a WhatsApp text message to a specific contact programmatically on an Android device, you've come to the right place. In this article, we'll provide you with step-by-step instructions on how to achieve this.

Step-by-Step Guide

Step 1: First, you need to add the WhatsApp API to your project. You can do this by adding the following dependency to your build.gradle file:


dependencies {
implementation 'com.twilio:twilio-java:7.0.0'
}

Step 2: Next, you need to create a Twilio account and get an API key. You can do this by visiting the Twilio website and signing up for an account.

Step 3: Once you have your API key, you can use the following code to send a WhatsApp message to a specific contact:


Twilio.init("YOUR_ACCOUNT_SID", "YOUR_AUTH_TOKEN");

Message message = Message
.creator(new PhoneNumber("whatsapp:+14155238886"), // to
new PhoneNumber("whatsapp:+15005550006"), // from
"Hello from Twilio!")
.create();

System.out.println(message.getSid());

Step 4: In the code above, replace "YOUR_ACCOUNT_SID" and "YOUR_AUTH_TOKEN" with your own Twilio account SID and auth token. Also, replace the "to" and "from" phone numbers with the phone numbers of the contact you want to send the message to and your Twilio phone number, respectively.

Step 5: Finally, run the code and your WhatsApp message will be sent to the specified contact.

Conclusion

In conclusion, sending a WhatsApp text message to a specific contact programmatically on an Android device is not a difficult task. By following the simple steps outlined in this article, you can easily achieve this.
