How to use GoogleAPIClient (deprecated) with SMSRetriver API in Android

问题

I am trying to implement SMS Retriever API for SMS verification. The official way mentioned in the documentation says to use GoogleApiClient along with HintRequest to retrieve the mobile number from the device

HintRequest hintRequest = new HintRequest.Builder()
            .setPhoneNumberIdentifierSupported(true)
            .build();

PendingIntent intent = Auth.CredentialsApi.getHintPickerIntent(
            googleApiClient, hintRequest);
try {
    startIntentSenderForResult(intent.getIntentSender(),
                RESOLVE_HINT, null, 0, 0, 0);
} catch (IntentSender.SendIntentException e) {
    e.printStackTrace();
}

But the GoogleAPIClient is deprecated and replaced by GoogleApi interface, such as GoogleSignInClient. I tried to use GoogleSignInClient but getHintPickerIntent does not accept it. Is it safe to use the old API even after being deprecated or is there a way to use the latter with SMSRetriver API?

回答1:

To remove the deprecated GoogleApiClient, replace your intent with the following:

// Kotlin
val intent = Credentials.getClient(this).getHintPickerIntent(hintRequest)

// Java
PendingIntent intent = Credentials.getClient(this).getHintPickerIntent(hintRequest);

Credentials is found in this package: com.google.android.gms.auth.api.credentials.Credentials.

Full working example which calls buttonClicked when a button is pressed:

// Kotlin

import android.app.Activity
import android.content.Intent
import android.os.Bundle
import android.view.View
import android.widget.Toast
import androidx.appcompat.app.AppCompatActivity
import com.google.android.gms.auth.api.credentials.Credential
import com.google.android.gms.auth.api.credentials.Credentials
import com.google.android.gms.auth.api.credentials.CredentialsApi
import com.google.android.gms.auth.api.credentials.HintRequest

class MyActivity : AppCompatActivity() {

    // ... onCreate Functions, etc

    // Arbitrary number to identify the request for crednetials
    private val iRequestCodePhoneNumber = 100

    // Button click listener
    fun buttonClicked(@Suppress("UNUSED_PARAMETER") view: View) {
        val hintRequest = HintRequest.Builder()
            .setPhoneNumberIdentifierSupported(true)
            .build()

        val intent = Credentials.getClient(this).getHintPickerIntent(hintRequest)

        startIntentSenderForResult(
            intent.intentSender,
            iRequestCodePhoneNumber, null, 0, 0, 0
        )
    }

    // Parse the result of the HintPicker (i.e., get the selected phone number)
    override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {
        super.onActivityResult(requestCode, resultCode, data)
        // resultCode:
        //   Activity.RESULT_OK (-1) = number selected
        //   Activity.RESULT_CANCELED (0) = user touched outside the HintPicker (do nothing)
        //   CredentialsApi.ACTIVITY_RESULT_OTHER_ACCOUNT (1001) = "None of the above" (do nothing; treat as same use case as 'Cancelling')
        //   CredentialsApi.ACTIVITY_RESULT_NO_HINTS_AVAILABLE (1002) = no numbers found, probably no SIM card
        if (requestCode == iRequestCodePhoneNumber && resultCode == Activity.RESULT_OK) {
            val credential: Credential? = data?.getParcelableExtra(Credential.EXTRA_KEY)
            val phoneNumber = credential?.id

            // *** Do something with the phone number here ***

        } else if (
            requestCode == iRequestCodePhoneNumber &&
            resultCode == CredentialsApi.ACTIVITY_RESULT_NO_HINTS_AVAILABLE
        ) {
            // *** No phone numbers available ***
            Toast.makeText(this, "No phone numbers found", Toast.LENGTH_LONG).show()
        }
    }
}

This will generate a popup like this:
