Firebase 电话身份验证不起作用

Question

In some android devices like android 10 my app crashes when i enter phone number and call following method

PhoneAuthProvider.verifyPhoneNumber(options);

as you can see log report recaptcha activity is not resuming due to some null pointer issue

java.lang.RuntimeException: Unable to resume activity {com.horizam.businessclient/com.google.firebase.auth.internal.RecaptchaActivity}: java.lang.NullPointerException: Attempt to invoke virtual method 'com.google.android.gms.internal.firebase-auth-api.zzat com.google.android.gms.internal.firebase-auth-api.zzdk.zza()' on a null object reference

Thanks in advance if you sort this out for me.

Okay I found solution to this problem. There was nothing wrong with code. It was Android Device that was not allowing browser to open to show Recaptcha screen. It is working now perfectly.
