How can I get my whatsapp number?

Question

I am developing an app for Android and want to read the whatsapp telephone number configured in the client device.

Tried the following code:

AccountManager am = AccountManager.get(this);
Account[] accounts = am.getAccounts();

for (Account ac : accounts) {
    String acname = ac.name;
    String actype = ac.type;
    // Take your time to look at all available accounts
    System.out.println("Accounts : " + acname + ", " + actype);
}

if(actype.equals("com.whatsapp")){
    String phoneNumber = ac.name;
}

I also set this permission: <uses-permission android:name="android.permission.GET_ACCOUNTS" />

but phoneNumber only returns "Whatsapp"

I need the user's whatsapp phone number as a record in my database. How can I get this phone number?

Answer 1

Follow these steps:

1. You need the rawcontact id of WhatsApp of that contact.
2. Query ContactsContract.Data table with mimetype = "vnd.android.cursor.item/vnd.com.whatsapp.profile" with that rawcontact id.
3. The DATA3 column is the number of WhatsApp.

Answer 2

WhatsApp have updated their process, and they no longer create the account using the phone number as the account name, which is the trick this code relied upon.

I do not believe there is any way to now get hold of the WhatsApp phone number from outside the WhatsApp app.
