This is the complete solution

public ArrayList<HashMap<String, Object>> getContacts() {

        ArrayList<HashMap<String, Object>> contacts = new ArrayList<HashMap<String, Object>>();

        if (contact.moveToFirst()) {

    }

    private String getAddress(int contactId) {
        String postalData = "";
        String addrWhere = ContactsContract.Data.CONTACT_ID + " = ? AND " + ContactsContract.Data.MIMETYPE + " = ?";
        String[] addrWhereParams = new String[] { String.valueOf(contactId), ContactsContract.CommonDataKinds.StructuredPostal.CONTENT_ITEM_TYPE };

        Cursor addrCur = managedQuery(ContactsContract.Data.CONTENT_URI, null, addrWhere, addrWhereParams, null);

        if (addrCur.moveToFirst()) {

    private String getPhoneNumber(int contactId) {

        final Cursor phone = managedQuery(Phone.CONTENT_URI, projection, Data.CONTACT_ID + "=?", new String[] { String.valueOf(contactId) }, null);

                phoneNumber = phoneNumber + phone.getString(contactNumberColumnIndex) + ";";
                phone.moveToNext();
            }

        }
        phone.close();
        return phoneNumber;
    }

How to use?

ArrayList<HashMap<String, Object>> contactList = getContacts();
        System.out.println("Contact List : " +contactList);

Output:

[
{
phone=992-561-1618;848-807-4440;, 
contactId=1, 
photo=android.graphics.Bitmap@44f40aa0, 
address=Zalavadia Strret
Manavadar, Gujarat 362630
India, 
email=birajzalavadia@gmail.com;biraj@tasolglobal.com;, 
name=Biraj Zalavadia
},
{
phone=992-511-1418;842-827-4450;, 
contactId=2, 
photo=android.graphics.Bitmap@44f40aa0, 
address=Makadiya Strret
Junagadh, Gujarat 364890
India, 
email=niles@gmail.com;niles@tasolglobal.com;, 
name=Niles patel
}
.......
]

NOTE:

You will get phone and email semicolon(;) separated if its more than one.
