Integrating WhatsApp with Android Application using Intent (Java/Kotlin)

To integrate WhatsApp with an Android application using Intent, you can use the following code.

Java Example

    To Send a message to a specific phone number:

    Intent sendIntent = new Intent("android.intent.action.SEND");
    sendIntent.putExtra("android.intent.extra.TEXT", "Your message here");
    sendIntent.putExtra("jid", "PHONE_NUMBER_HERE");

    To share a file:

    Intent shareIntent = new Intent("android.intent.action.SEND");
    shareIntent.setType("image/jpeg"); // Or any other file type
    shareIntent.putExtra("android.intent.extra.STREAM", Uri.parse("file:///path/to/your/file.jpg"));
    shareIntent.putExtra("jid", "PHONE_NUMBER_HERE");

Using Kotlin:

    To Send a message to a specific phone number:

    val sendIntent = Intent("android.intent.action.SEND")
    sendIntent.type = "text/plain"
    sendIntent.putExtra("android.intent.extra.TEXT", "Your message here")
    sendIntent.putExtra("jid", "PHONE_NUMBER_HERE")

    To share a file:

    val shareIntent = Intent("android.intent.action.SEND")
    shareIntent.type = "image/jpeg" // Or any other file type
    shareIntent.putExtra("android.intent.extra.STREAM", Uri.parse("file:///path/to/your/file.jpg"))
    shareIntent.putExtra("jid", "PHONE_NUMBER_HERE")


  • Replace PHONE_NUMBER_HERE with the actual phone number of the WhatsApp contact you want to send the message to.

  • The above code will only work if the user has WhatsApp installed on their device.
  • The jid extra is used to specify the phone number of the WhatsApp contact.
