Android Question Google Play Services - Phone Selector and SMS Retriever

[Semen Matusovskiy]

Hi, guys --
Has anybody tried them ?

My app already uses SMS verification, but there are two problems --
1) At first, SMS are not free (cheaper than in Firebase Phone Auth, but anyway)
2) User must type verification code from SMS-message.
Theoretically, I can read SMS, but I want to avoid permission requests, which are able to confuse user (READ_SMS, SMS_SEND etc.)

As I understand, Phone Selector and SMS Retriever do not require additional permissions.

You cannot read SMS messages without permission.

If to believe blogs, for example, https://android-developers.googleblog.com/2017/10/effective-phone-number-verification.html permissions are not needed. Similar using intent for camera.

I hope that Phone Selector, which, probably reads call logs and etc., is able to offer telephone number, which I can compare with typed by user.
If these numbers will be the same, there are no reasons to use SMS. Unlike SMS confirmation is more reliable.

I wasn't familiar with this service.

The code to start SmsRetreiver is quite simple and can be easily implemented with JavaObject: https://developers.google.com/identity/sms-retriever/request

Follow these instructions to understand how to build the SMS message: https://developers.google.com/identity/sms-retriever/verify

I can then help you with the JavaObject code.
