Android Question How to know if a Phonenumber has WhatsApp installed?

[MODERN TALKING]

Hi guys and gals and in-betweeners,

Is there any way to know if a Contact has WhatsApp installed?

I wanted to ask in ContactsUtils - but I think Erel prefers a new thread for this

Thanking you in advance

Does this REALLY belong to the QUESTION???????

 

[DonManfred]

You know who they are?

Hopefully in Jail or burried

No one in Germany is interested in these F*** people.

We are going OffTopic

Back to topic - you have solution Herr Kommisar?

I cannot answer your initial question....

But if you are planning to send whatsapp messages automaticaly, it is probably not possible (afaik), cause whatsapp restricted the access.

But An Schi, Modern Talking tells me "YOU CAN WIN IF YOU WANT"

Curious to know how these guys and a host of others are doing it though - seems possible:

1. STOP posting your stuff about modern talkking, Dieter Bohlen and who ever. No one is interested in these comments here. It is also NOT RELEVANT for this forum at all!

seems possible:

Get WhatsApp Bulk Sender Standard License For Only $1997 - NOT FOR SALE ANYMORE

I´m not a Kommandant. I´m not in the army
About your issue. All the tools which says it can be done in the past where using hacks to stop whatsapp, open the whatsapp-database and insert things there and then they do start whatsapp again.

There is only a very limited "Api" to send whatsapp messages. But no one to send a message completely without user intervention.
There is also no api to know if whatsapp is installed on the device with number xy.

Thank you for the info Manfred

Much appreciated

They limit so much how you can interact with their App. Never used iOS but I have read Apple is FAR WORSE, like a Communist Regime FULL SPECTRUM DOMINATION control
