Phone number detect android studio (JAVA) using Google Api

Demo:

Why we need  this feature :

•      No additional permission required
•     Do not required to enter phone number manually 
•     No Google account is required

Step 1 : Add dependency

    implementation 'com.google.android.gms:play-services-auth:19.0.0'
    implementation 'com.google.android.gms:play-services-identity:17.0.0'
    implementation 'com.google.android.gms:play-services-auth-api-phone:17.5.0'
    implementation 'com.google.android.gms:play-services-base:17.5.0'

Step 2 : MainActivity.java

import androidx.appcompat.app.AppCompatActivity;
import android.app.PendingIntent;
import android.content.Intent;
import android.content.IntentSender;
import android.os.Bundle;
import android.view.View;
import android.widget.Toast;

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;

public class MainActivity extends AppCompatActivity {
    private static final int CREDENTIAL_PICKER_REQUEST =120 ;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        getPhoneNumber();

        findViewById(R.id.change_number).setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                getPhoneNumber();
            }
        });
    }

    private void getPhoneNumber(){
        HintRequest hintRequest = new HintRequest.Builder()
                .setPhoneNumberIdentifierSupported(true)
                .build();

        PendingIntent intent = Credentials.getClient(MainActivity.this).getHintPickerIntent(hintRequest);
        try
        {
            startIntentSenderForResult(intent.getIntentSender(), CREDENTIAL_PICKER_REQUEST, null, 0, 0, 0,new Bundle());
        }
        catch (IntentSender.SendIntentException e)
        {
            e.printStackTrace();
        }
    }
    @Override
    public void onActivityResult(int requestCode, int resultCode, Intent data)
    {
        super.onActivityResult(requestCode, resultCode, data);
        if (requestCode == CREDENTIAL_PICKER_REQUEST && resultCode == RESULT_OK)
        {
            // Obtain the phone number from the result
            Credential credentials = data.getParcelableExtra(Credential.EXTRA_KEY);
            /* EditText.setText(credentials.getId().substring(3));*/ //get the selected phone number
            //Do what ever you want to do with your selected phone number here
            Toast.makeText(this, "MOB"+credentials.getId().substring(3), Toast.LENGTH_SHORT).show();
        }
        else if (requestCode == CREDENTIAL_PICKER_REQUEST && resultCode == CredentialsApi.ACTIVITY_RESULT_NO_HINTS_AVAILABLE)
        {
            // *** No phone numbers available ***
            Toast.makeText(MainActivity.this, "No phone numbers found", Toast.LENGTH_LONG).show();
        }
    }
}
