Hi, everyone. I tried some options using WhatsApp tools 1 but got stuck in making Whatsapp app open when I click a button. I appreciate any kind of help to make this work. Regards.

You don't need extensions for this, use activity.

Hello Marcio

You can open WhatsApp using an Activity Starter:

Thank you all for your help. I'll try them and give you a feedback.

You can also prepare a text to send and open whatsapp on the contact picker page. The user can select a contact and send your text.

Action: android.intent.action.SEND
ActivityClass: com.whatsapp.contact.picker.ContactPicker
ActivityPackage: com.whatsapp
ExtraKey: android.intent.extra.TEXT
ExtraValue: "your text to send"

The remote app (on the same phone) should be able to send a notification on the phone's WhatsApp itself.

It is possible to send a message to WhatsApp using the activity starter without selecting the Contact picker, that is, without using the Class:
com.whatsapp.contact.picker.ContactPicker ?

Infinite Thanks!
David
