How to share text to WhatsApp from my app?

Question

I develop an app with a functionality for sharing text. This is working fine except for WhatsApp. What should I do? Is there any specific API for that?

Answer 1

  Intent sendIntent = new Intent();
    sendIntent.setAction(Intent.ACTION_SEND);
    sendIntent.putExtra(Intent.EXTRA_TEXT, "This is my text to send.");
    sendIntent.setType("text/plain");
sendIntent.setPackage("com.whatsapp");
    startActivity(sendIntent);
