Failed to identify WhatsApp contacts
I am trying to write an Android program that can detect if a given contact number is associated with WhatsApp or not. I was able to figure out if a particular contact name has a WhatsApp account or not. How do I know which contact matches that WhatsApp contact name? I am currently using the following code:
public void identifyWhatsappContact() {
Cursor c = ctx.getContentResolver().query(
RawContacts.CONTENT_URI,
new String[] { RawContacts.CONTACT_ID, RawContacts.DISPLAY_NAME_PRIMARY },
RawContacts.ACCOUNT_TYPE + "= ? AND " + StructuredName.DISPLAY_NAME_PRIMARY + " = ?",
new String[] { "com.whatsapp", "John Doe" },
null);
ArrayList<String> myWhatsappContacts = new ArrayList<String>();
int contactNameColumn = c.getColumnIndex(RawContacts.DISPLAY_NAME_PRIMARY);
while (c.moveToNext())
{
myWhatsappContacts.add(c.getString(contactNameColumn));
Log.v("WHATSAPP", c.getString(contactNameColumn)+"");
}
}
I can tell if "John Doe" has WhatsApp or not, but I cannot figure out which phone number "John Doe" has WhatsApp (assuming the contact has multiple phone numbers). Can anyone help me? I've already tried the solution here , but it doesn't work for me.

In this example, output all WhatsApp numbers of the contact's name:
public void getWhatsAppNumbers(String contactName) {
Cursor cursor1 = getContentResolver().query(
ContactsContract.RawContacts.CONTENT_URI,
new String[]{ContactsContract.RawContacts._ID},
ContactsContract.RawContacts.ACCOUNT_TYPE + "= ? AND " + ContactsContract.CommonDataKinds.StructuredName.DISPLAY_NAME_PRIMARY + " = ?",
new String[]{"com.whatsapp", contactName},
null);
while (cursor1.moveToNext()) {
String rawContactId = cursor1.getString(cursor1.getColumnIndex(ContactsContract.RawContacts._ID));
Cursor cursor2 = getContentResolver().query(
ContactsContract.Data.CONTENT_URI,
new String[]{ContactsContract.Data.DATA3},
ContactsContract.Data.MIMETYPE + " = ? AND " + ContactsContract.Data.RAW_CONTACT_ID + " = ? ",
new String[]{"vnd.android.cursor.item/vnd.com.whatsapp.profile", rawContactId},
null);
while (cursor2.moveToNext()) {
String phoneNumber = cursor2.getString(0);
if (TextUtils.isEmpty(phoneNumber))
continue;
if (phoneNumber.startsWith("Message "))
phoneNumber = phoneNumber.replace("Message ", "");
Log.d("whatsapp", String.format("%s - %s", contactName, phoneNumber));
}
}
}
