android - Firebase phone auth response with null token -


i migrating digits authentication firebase authentication following these official links: https://firebase.google.com/support/guides/digits-android https://github.com/firebase/firebaseui-android/blob/master/auth/readme.md

google-services.json file exported firebase console it's integrated on project.

i using drop-in solution ui , code:

startactivityforresult(                 authui.getinstance()                         .createsigninintentbuilder()                         .setproviders(arrays.aslist(                                 new authui.idpconfig.builder(authui.phone_verification_provider).build())).build(), rc_sign_in);  @override protected void onactivityresult(int requestcode, int resultcode, intent data) {     super.onactivityresult(requestcode, resultcode, data);     if (requestcode == rc_sign_in) {         idpresponse response = idpresponse.fromresultintent(data);          // signed in         if (resultcode == result_ok) {             idpresponse idpresponse = idpresponse.fromresultintent(data);              //here retreive token response             idpresponse.getidptoken();             finish();             return;         } else {             // sign in failed             if (response == null) {                 // user pressed button                 return;             }              if (response.geterrorcode() == errorcodes.no_network) {                 toast.maketext(this, getstring(r.string.connection_error), toast.length_short).show();                 return;             }              if (response.geterrorcode() == errorcodes.unknown_error) {                 toast.maketext(this, getstring(r.string.error_default), toast.length_short).show();                 return;             }         }          toast.maketext(this, "error", toast.length_short).show();     } } 

and interesting part of build.gradle:

android { compilesdkversion 26 buildtoolsversion '26.0.1' 

}

compile 'com.firebaseui:firebase-ui-auth:2.3.0' compile 'com.android.support:appcompat-v7:26.0.1' compile 'com.android.support:support-v4:26.0.1' compile 'com.android.support:recyclerview-v7:26.0.1' compile 'com.android.support:design:26.0.1' compile 'com.android.support:support-core-utils:26.0.1' compile 'com.android.support:support-annotations:26.0.1' compile 'com.android.support:percent:26.0.1' 

when onactivityresult it's fired, response successful token null.

i don't know if authentication provider, token it's null or i'm doing wrong.

thanks in advance!!
