SignInButton does not render Hindi font on api level 19

[rinav]

Step 2: Describe your environment

• Android Studio version: 3.3 RC2
• Firebase Component: Auth
• Component version: firebase-auth:16.1.0 and play-services-auth:16.0.1

Step 3: Describe the problem

I am developing an app in Hindi and using Firebase auth for Google SignIn. My default font is Hindi and
SignInButton button does not render hindi font on API level 19.
Moreover the button text is blank.

Steps to reproduce:

If you run this code on API Level 19, with Hindi font it does not render it.

Relevant Code:

<com.google.android.gms.common.SignInButton
                android:id="@+id/google_sign_in"
                android:layout_width="300dp"
                android:layout_height="wrap_content"
                android:layout_marginStart="8dp"
                android:layout_marginTop="16dp"
                android:layout_marginEnd="8dp"
                app:layout_constraintEnd_toEndOf="parent"
                app:layout_constraintStart_toStartOf="parent"
                app:layout_constraintTop_toBottomOf="@+id/auth_message"/>

Need a way to change font based on locale either programmatically or via XML android:fontFamily="@font/hindi_font"

@rinav thanks for filing this! This is not a Firebase issue so I am going to close it here (there's nothing I can do about it personally) but I am going to copy all of this into an internal bug report with the Google Sign In team so they can hopefully fix it.
