Uri uri = Uri.parse("whatsapp://send?phone=8618800008888");

If this mobile number 8618800008888 has registered WhatsApp,
Will directly enter the chat page of this number,.
There are two states, one is directly entering the chat page, the other is that the mobile number is not registered.
The status can be used to capture whether this phone number has registered WhatsApp
We can get the phone number status through Android interface rendering, or through
Write a simple xposed module to get the status, or grab the package.
Scheme is just a simple way to judge,
There is a more efficient way, through the address book.
