Retrieve whatsapp contacts from phonebook in android

Question

When i was looking through my contacts in phone i see whatsapp number also for those who have whatsapp account.The thing which i want to do is filter my contact list and display numbers which are synced with whatsapp.I am successfully retrieving all the contact id,number and account associated with it but not displaying whatsappaccount.Only associated google account is getting displayed.Is there any way to get whatsapp contact from local phonebook itself? I used the following code:

ContentResolver cr1 = getContentResolver();
Cursor cur = cr1.query(ContactsContract.Contacts.CONTENT_URI, null, null, null, null);
    if (cur.getCount() > 0) 
    {
        while (cur.moveToNext()) 
        {
            String id = cur.getString(cur.getColumnIndex(ContactsContract.Contacts._ID));
            String name = cur.getString(cur.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));
            if (Integer.parseInt(cur.getString(cur.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER))) > 0) 
            {
                Cursor pCur = cr1.query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null, ContactsContract.CommonDataKinds.Phone.CONTACT_ID + " = ?", new String[] { id }, null);
                while (pCur.moveToNext()) 
                {
                    //phoneContactList.add(name);
                    Log.i("Contact List", name);
                    Log.i("Contact List", id);
                    
                    getContactAccount(id,cr1);
                }
                pCur.close();
            }
        }
    }


public void getContactAccount(String id,ContentResolver contentResolver){
        Cursor cursor = null;
        try {
             cursor = contentResolver.query(ContactsContract.RawContacts.CONTENT_URI,
                     new String[]{ContactsContract.RawContacts.ACCOUNT_NAME, ContactsContract.RawContacts.ACCOUNT_TYPE},
                     ContactsContract.RawContacts.CONTACT_ID +"=?",
                     new String[]{String.valueOf(id)},
                     null);
             
            if (cursor != null && cursor.getCount() >0){
                cursor.moveToFirst();
                System.out.println("Account name is"+cursor.getString(cursor.getColumnIndex(ContactsContract.RawContacts.ACCOUNT_NAME)));
                System.out.println("Account type is"+cursor.getString(cursor.getColumnIndex(ContactsContract.RawContacts.ACCOUNT_TYPE)));
                cursor.close();
            }
        } catch (Exception e) {
            System.out.println(""+this.getClass().getName()+","+ e.getMessage());
        } finally{
          cursor.close();
        }
    }

The MIME type for whatsapp is:  "vnd.android.cursor.item/vnd.com.whatsapp.profile"

Use the following code`:

public class MainActivity extends ActionBarActivity {


    @Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    if (savedInstanceState == null) {
        getSupportFragmentManager().beginTransaction()
                .add(R.id.container, new PlaceholderFragment()).commit();
    }
}

@Override
public boolean onCreateOptionsMenu(Menu menu) {

    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.main, menu);
    return true;
}

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    // Handle action bar item clicks here. The action bar will
    // automatically handle clicks on the Home/Up button, so long
    // as you specify a parent activity in AndroidManifest.xml.
    int id = item.getItemId();
    if (id == R.id.action_settings) {
        return true;
    }
    return super.onOptionsItemSelected(item);
}

Use following code to get WhatsApp contacts from phonebook with associated WhatsApp number :

private void displayWhatsAppContacts() {

    final String[] projection = {
            ContactsContract.Data.CONTACT_ID,
            ContactsContract.Data.DISPLAY_NAME,
            ContactsContract.Data.MIMETYPE,
            "account_type",
            ContactsContract.Data.DATA3,
    };

    final String selection = ContactsContract.Data.MIMETYPE + " =? and account_type=?";
    final String[] selectionArgs = {
            "vnd.android.cursor.item/vnd.com.whatsapp.profile",
            "com.whatsapp"
    };

    ContentResolver cr = getContentResolver();
    Cursor c = cr.query(
            ContactsContract.Data.CONTENT_URI,
            projection,
            selection,
            selectionArgs,
            null);

    while (c.moveToNext()) {
        String id = c.getString(c.getColumnIndex(ContactsContract.Data.CONTACT_ID));
        String number = c.getString(c.getColumnIndex(ContactsContract.Data.DATA3));
        String name = c.getString(c.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));

        Log.v("WhatsApp", "name " +name + " - number - "+number);

    }
    Log.v("WhatsApp", "Total WhatsApp Contacts: " + c.getCount());
    c.close();
}
