FirebaseAuth crash on captcha link when no browser is installed

[adiliqbl]

Hi, we're using Firebase Auth's phone number method for users to signin. We've seen crashes when user doesn't have a browser installed & firebase tries opens captcha link. Crash is always a bad experience for users & since I believe there's nothing we can do here, maybe it would be nice to have exception thrown instead of causing a crash.

Steps to reproduce:

• Browser app doesn't exist

Observed Results:

• Application crashes with:

No Activity found to handle Intent { act=android.intent.action.VIEW }
    android.app.Instrumentation.checkStartActivityResult (Instrumentation.java:1809)
    com.google.firebase.auth.internal.RecaptchaActivity.zzf (com.google.firebase:firebase-auth@@21.0.1:12)
    com.google.android.gms.internal.firebase-auth-api.zztr.zza (com.google.firebase:firebase-auth@@21.0.1:7)
    com.google.android.gms.internal.firebase-auth-api.zztr.onPostExecute (com.google.firebase:firebase-auth@@21.0.1:2)

Expected Results:

• Exception thrown for captcha handling
