I m really late here but I believe that nowadays we have shorter and better solutions to send messages through WhatsApp   You can use the following to call the system picker  then choose which app you will use to share whatever you want   Intent sendIntent   new Intent    sendIntent setAction Intent ACTION SEND   sendIntent putExtra Intent EXTRA TEXT   This is my text to send     sendIntent setType  text plain    startActivity sendIntent     If you are really need to send through WhatsApp all you need to do is the following  You will skip the system picker    Intent sendIntent   new Intent        sendIntent setAction Intent ACTION SEND       sendIntent putExtra Intent EXTRA TEXT   This is my text to send         sendIntent setType  text plain           Put this line here     sendIntent setPackage  com whatsapp               startActivity sendIntent     If you need more information you can find it here  WhatsApp FAQ

The following code is used by Google Now App and will NOT work for any other application   I m writing this post because it makes me angry  that WhatsApp does not allow any other developers to send messages directly except for Google   And I want other freelance-developers to know  that this kind of cooperation is going on  while Google keeps talking about  open for anybody  and WhatsApp says they don t want to provide any access to developers   Recently WhatsApp has added an Intent specially for Google Now  which should look like following   Intent intent   new Intent  com google android voicesearch SEND MESSAGE TO CONTACTS    intent setPackage  com whatsapp    intent setComponent new ComponentName  com whatsapp    com whatsapp VoiceMessagingActivity      intent putExtra  com google android voicesearch extra RECIPIENT CONTACT CHAT ID   number   intent putExtra  android intent extra TEXT   text   intent putExtra  search action token             I could also find out that  search action token  is a PendingIntent that contains an IBinder-Object  which is sent back to Google App and checked  if it was created by Google Now   Otherwise WhatsApp will not accept the message

You ll want to use a URL in the following format     https   api whatsapp com send text text   Then you can have it send whatever text you d like   You also have the option to specify a phone number     https   api whatsapp com send text text amp phone 1234   What you CANNOT DO is use the following   https   wa me send text text   You will get        We couldn t find the page you were looking for   wa me  though  will work if you supply both a phone number and text   But  for the most part  if you re trying to make a sharing link  you really don t want to indicate the phone number  because you want the user to select someone   In that event  if you don t supply the number and use wa me as URL  all of your sharing links will fail   Please use app whatsapp com

From the documentation     To create your own link with a pre-filled message that will   automatically appear in the text field of a chat  use   https   wa me whatsappphonenumber  text urlencodedtext where   whatsappphonenumber is a full phone number in international format and   URL-encodedtext is the URL-encoded pre-filled message       Example https   wa me 15551234567 text I m 20interested 20in 20your 20car 20for 20sale   Code example  val phoneNumber    13492838472      val text    Hey  you know    I love StackOverflow         val uri   Uri parse  https   wa me  phoneNumber  text  text       val sendIntent   Intent Intent ACTION VIEW  uri      startActivity sendIntent
