I have an app and we want the following

• Type message in this app(not whatsapp)
• Our app knows the user from the contact list
• Click send
• Message should be sent to the user without whatsapp asking for the user except maybe in special case of multiple phone numbers maybe?
• Message sent should show up in whatsapp history as part of the chat with the targetted user

Is this even possible? The post I read makes the user go into whatsapp and select the user to send the message to. Is that unavoidable?

CodePudding user response：

correct. the user has to go into whatsapp and select the user to send the message to. that is unavoidable.

If you want to pre-fill a message you can do so by using a custom URL scheme whatsapp://send?text=followed by the text to send or by setting an extra on the send intent sendIntent.putExtra(Intent.EXTRA_TEXT, "This is my text to send."); Both will allow the user to choose a contact, and pre-fill the input field with the specified text.
