Send text to specific contact programmatically whatsapp

Question

I wanted to know how I can send text to a specific whatsapp contact  I found some code to view a specific contact  but not to send data   Cursor c   getContentResolver   query ContactsContract Data CONTENT URI      new String     ContactsContract Contacts Data  ID    ContactsContract Data DATA1             new String     id    null   c moveToFirst    Intent i   new Intent Intent ACTION VIEW  Uri parse  content   com android contacts data     c getString 0      startActivity i   c close      This works fine for viewing a whatsapp-contact  but how can I add some text now  Or didn t the Whatsapp-developer implement such kind of an api

This is now possible through the WhatsApp Business API. Only businesses may apply to use it. This is the only way to directly send messages to phone numbers, without any human interaction.

Sending normal messages is free. It looks like you need to host a MySQL database and the WhatsApp Business Client on your server.

I think the answer is a mix of your question and this answer here  https   stackoverflow com a 15931345 734687 So I would try the following code    change ACTION VIEW to ACTION SENDTO set the Uri as you did set the package to whatsapp   Intent i   new Intent Intent ACTION SENDTO  Uri parse  content   com android contacts data     c getString 0     i setType  text plain    i setPackage  com whatsapp                 so that only Whatsapp reacts and not the chooser i putExtra Intent EXTRA SUBJECT   Subject    i putExtra Intent EXTRA TEXT   I m the body     startActivity i     I looked into the Whatsapp manifest and saw that ACTION SEND is registered to the activity ContactPicker  so that will not help you  However ACTION SENDTO is registered to the activity com whatsapp Conversation which sounds more adequate for your problem   Whatsapp can work as a replacement for sending SMS  so it should work like SMS  When you do not specify the desired application  via setPackage  Android displays the application picker  Thererfor you should just look at the code for sending SMS via intent and then provide the additional package information   Uri uri   Uri parse  smsto     smsNumber   Intent i   new Intent Intent ACTION SENDTO  uri   i putExtra  sms body   smsText     i setPackage  com whatsapp      startActivity i     First try just to replace the intent ACTION SEND to ACTION SENDTO   If this does not work than provide the additional extra sms body  If this does not work than try to change the uri   Update I tried to solve this myself and was not able to find a solution  Whatsapp is opening the chat history  but doesn t take the text and send it  It seems that this functionality is just not implemented

Whatsapp and most other apps that integrate into the Android core components  like Contacts  use a mime-type based intent to launch a certain Activity within the application  Whatsapp uses 3 separate mimetypes - text messages  vnd android cursor item vnd com whatsapp profile   voip calls  vnd android cursor item vnd com whatsapp voip call  and video calls vnd android cursor item vnd com whatsapp video call   For each of these mimetypes  a separate activity is mapped inside the Manifest of the application  For ex  the mimetype     whatsapp profile  maps to an Activity  com whatsapp Conversation   You can see these in detail if you dump out all the Data rows that maps to any Whatsapp Raw Contact in your Contacts database    This is also how the Android Contacts app shows 3 separate rows of user action inside a  Whatsapp contact   and clicking either of these rows launches a separate function inside Whatsapp   To launch a Conversation  chat  Activity for a certain contact in Whatsapp  you need to fire an intent containing MIME TYPE and DATA URL  The mimetype points to the mimetype corresponding to your action as defined inside Whatsapp s Raw Contact in Contacts database  The DATA URL is the URI of the Raw Contact in the Android contacts database   String whatsAppMimeType   Uri parse  vnd android cursor item   buildUpon                                        appendEncodedPath  vnd com whatsapp profile   build   toString     Uri uri   ContactsContract RawContacts CONTENT URI buildUpon            appendQueryParameter ContactsContract RawContacts ACCOUNT TYPE   com whatsapp            appendQueryParameter ContactsContract RawContacts ACCOUNT NAME   WhatsApp            build     Cursor cursor   getContentResolver   query uri  null  null  null   if  cursor  null    cursor getCount    0  continue   cursor moveToNext    int rawContactId   cursor getInt cursor getColumnIndex ContactsContract RawContacts  ID    cursor close        now search for the Data row entry that matches the mimetype and also points to this RawContact Cursor dataCursor   getContentResolver   query ContactsContract Data CONTENT URI          null          ContactsContract Data MIMETYPE       AND     ContactsContract Data RAW CONTACT ID                 new String   whatsAppMimeType  String valueOf rawContactId    null   if  dataCursor  null    dataCursor getCount    0  continue   dataCursor moveToNext    int dataRowId   dataCursor getInt dataCursor getColumnIndex ContactsContract Data  ID     Uri userRowUri   ContactsContract Data CONTENT URI buildUpon                            appendPath String valueOf dataRowId   build         launch the whatsapp user chat activity Intent intent   new Intent Intent ACTION VIEW   intent setDataAndType userRowUri  whatsAppMimeType   startActivity intent    dataCursor close      This is the same way that all Contacts app use to launch a chat Activity for a Whatsapp contact  Inside this Activity  the application  Whatsapp  reads in the  getData   to get the DATA URI which was passed to this Activity  The Android Contacts app uses a standard mechanism to use the URI of the Raw Contact in Whatsapp  Unfortunately  I am not aware of a way by which the  Conversation ativity in Whatsapp reads in any text   data information from the caller of the intent  This basically means that its possible  using a very standard technique  to launch a certain  user action  inside Whatsapp  Or for that matter  any similar app

This approach works with WhatsApp Business app as well   Change package name as sendIntent setPackage  com whatsapp w4b    for WhatsApp Business   Great hack Rishabh  thanks a lot  I was looking for this solution since last 3 years   As per the Rishabh Maurya s answer above  I have implemented this code which is working fine for both text and image sharing on WhatsApp   Note that in both the cases it opens a whatsapp conversation  if toNumber exists in users whatsapp contact list   but user have to click send button to complete the action  That means it helps in skipping contact selection step   For text messages  String toNumber     91 98765 43210      contains spaces  toNumber   toNumber replace          replace            Intent sendIntent   new Intent  android intent action MAIN    sendIntent putExtra  jid   toNumber     s whatsapp net    sendIntent putExtra Intent EXTRA TEXT  message   sendIntent setAction Intent ACTION SEND   sendIntent setPackage  com whatsapp    sendIntent setType  text plain    startActivity sendIntent     For sharing images  String toNumber     91 98765 43210      contains spaces  toNumber   toNumber replace          replace            Intent sendIntent   new Intent  android intent action MAIN    sendIntent putExtra Intent EXTRA STREAM  Uri fromFile imageFile    sendIntent putExtra  jid   toNumber     s whatsapp net    sendIntent putExtra Intent EXTRA TEXT  message   sendIntent setAction Intent ACTION SEND   sendIntent setPackage  com whatsapp    sendIntent setType  image png    context startActivity sendIntent     Enjoy WhatsApping
