B bixmatech Member Licensed User Jul 22, 2017 #1 Hi.. I'm using whatsapp library , and I've a question about it . https://www.b4x.com/android/forum/threads/whatsapp-library.51571/#content I want to add new contact on whatsapp and chat with him. 1- I checked if the contact is already exist. Code: Copy If whapp.existPhoneNumber("+9999999") == False Then whapp.createPhoneNumber("name", "+9999999", "email") End If 2- Openning chat with him by this code : Code: Copy whapp.OpenChatWithNumber("+9999999") - The problem : whatsapp need some time to refresh his list and to recognize the new contact , so when using the above code , always will show me a message that this contact does not have whatsapp. So I close my app , open whatsapp , wait for a seconds , and then the whatsapp icon will show in the new contact , and the above code will work too. My question : Is there any way to check by my app if the new contact is recognized by whatsapp ? if yes will use the code "OpenCheatWithNumber" , if not , will keep the waiting message. are there another library or code to solve my problem ? Thank you in advanced .
