Bear in mind that `getLine1Number()` does not have to return the user's phone number. — CommonsWare, Apr 13 '16 at 13:07
I think phone numbers are stored in SIM cards. you can only get serial number. — Praveen Kumar, Apr 13 '16 at 13:09
@CommonsWare always correct. Please look at this answer http://stackoverflow.com/questions/18894080/get-my-phone-number-in-android — Raghu Mudem, Apr 13 '16 at 13:10
Use LogCat to examine the logs and look for the Java stack trace associated with your crash: http://stackoverflow.com/questions/23353173/unfortunately-myapp-has-stopped-how-can-i-solve-this. You can then click the "edit" link under your question, paste in the Java stack trace, and format it as source (as you did some of the other lines in your question). — CommonsWare, Apr 13 '16 at 13:12
@CommonsWare so how can i get the phone number automatically? im new to android development. — Umair Munawar Khokhar, Apr 13 '16 at 13:13
Please try the ways given in comments and ask questions later. — Raghu Mudem, Apr 13 '16 at 13:14
```java.lang.SecurityException: getLine1NumberForDisplay: Neither user 10097 nor current process has android.permission.READ_SMS.``` points out that you are missing at least the ```READ_SMS``` permission. — lippertsjan, Apr 13 '16 at 13:18

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 (e.g. 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();
        }
    }
}
