title: How can I send message to specific contact through WhatsApp from my android app?
body: <p>I am developing an android app and I need to send a message to specific contact from WhatsApp.
  I tried this code:</p>
  
  <pre><code>Uri mUri = Uri.parse("smsto:+999999999");
  Intent mIntent = new Intent(Intent.ACTION_SENDTO, mUri);
  mIntent.setPackage("com.whatsapp");
  mIntent.putExtra("sms_body", "The text goes here");
  mIntent.putExtra("chat",true);
  startActivity(mIntent);
  </code></pre>
  
  <p>The problem is that the parameter "sms_body" is not received on WhatsApp, though the contact is selected.</p>
