getLine1Number() Returns blank, not null [duplicate]

Answer 1

I have another solution to get a phone number when telephony manager returns blank. I hope it'll help you.

Here is my sample code:

public static final String main_data[] = {
            "data1", "is_primary", "data3", "data2", "data1", "is_primary", "photo_uri", "mimetype"
    };


        object object = (TelephonyManager) context.getSystemService("phone");
        if (!TextUtils.isEmpty(((TelephonyManager) (object)).getLine1Number())) {

        }
        object = context.getContentResolver().query(Uri.withAppendedPath(android.provider.ContactsContract.Profile.CONTENT_URI, "data"), main_data, "mimetype=?", new String[]{
                "vnd.android.cursor.item/phone_v2"
        }, "is_primary DESC");
        if (object != null) {
            do {
                if (!((Cursor) (object)).moveToNext()) {
                    break;
                }

             if (s.equals("vnd.android.cursor.item/phone_v2")) {
                    String s1 = ((Cursor) (object)).getString(4);
                    boolean flag1;
                    if (((Cursor) (object)).getInt(5) > 0) {
                        flag1 = true;
                    } else {
                        flag1 = false;
                    }
                    Toast.makeText(SampleActivity.this, "Phone:-" + s1, Toast.LENGTH_LONG).show();
                }
            } while (true);
            ((Cursor) (object)).close();
        }

Also don't forget to add these two permissions:
