Answer 1

Hello can share logcat.

There is no guaranteed solution to this problem because the phone number is not physically stored on all SIM-cards, or broadcasted from the network to the phone. This is especially true in some countries which requires physical address verification, with number assignment only happening afterwards. Phone number assignment happens on the network - and can be changed without changing the SIM card or device (eg this is how porting is supported).

I know it is pain, but most likely the best solution is just to ask the user to enter his/her phone number once and store it.

Umair,

You can copy all phonebook contact and insert own app db

 public void fetchContacts() {
        ////Log.e("step ", "1");
        String phoneNumber, phonetype = null;

        Uri CONTENT_URI = ContactsContract.Contacts.CONTENT_URI;
        String _ID = ContactsContract.Contacts._ID;
        String DISPLAY_NAME = ContactsContract.Contacts.DISPLAY_NAME;
        String HAS_PHONE_NUMBER = ContactsContract.Contacts.HAS_PHONE_NUMBER;
        Uri PhoneCONTENT_URI = ContactsContract.CommonDataKinds.Phone.CONTENT_URI;
        String Phone_CONTACT_ID = ContactsContract.CommonDataKinds.Phone.CONTACT_ID;
        String NUMBER = ContactsContract.CommonDataKinds.Phone.NUMBER;

        ContentResolver contentResolver = getContentResolver();
        Cursor cursor = contentResolver.query(CONTENT_URI, null, null, null, null);

        // Loop for every contact in the phone
        if (cursor.getCount() > 0) {

            while (cursor.moveToNext()) {
                String contact_id = cursor.getString(cursor.getColumnIndex(_ID));
                String name = cursor.getString(cursor.getColumnIndex(DISPLAY_NAME));

                int hasPhoneNumber = Integer.parseInt(cursor.getString(cursor.getColumnIndex(HAS_PHONE_NUMBER)));
                if (hasPhoneNumber > 0) {
                    Cursor phoneCursor = contentResolver.query(PhoneCONTENT_URI, null, Phone_CONTACT_ID + " = ?"
                            , new String[]{contact_id}, DISPLAY_NAME);
                    while (phoneCursor.moveToNext()) {
                        phoneNumber = phoneCursor.getString(phoneCursor.getColumnIndex(NUMBER));
                        String string = phoneNumber.replaceAll("[^\\d]", "");
                        // String where2 = childJSONObject.getString("phone_number");
                        if (string.length() > 10)
                            string = string.substring(string.length() - 10);
                        JSONObject object = new JSONObject();
                        if (ValidationUtil.isValidMobileNumber(string)) {
                            if (string.length() > 2) {
                                try {
                                    object.put("name", helper.ConvertCamel(name));
                                    object.put("phone", Long.parseLong(string.trim()));
                                    objects.add(object);
                                } catch (Exception e) {
                                    e.printStackTrace();
                                }
                            }
                        }
                    }
                    phoneCursor.close();
                }
            }
            cursor.close();
        }
    }
}
