Flutter Firebase Android 上的电话验证错误

Question

I want to verify the Phone number with Firebase Auth but it gives the following error,

Notes: My sha1 and sha256 keys are attached. It works when I manually add the phone number to firebase. Works smoothly on iOS devices.

Answer 1

I have the same error because I generated my sha1 certificate through vscode terminal which is bad if you want phone auth. so i fixed by

1. open my android folder through android studio
2. click .android/app/build.gradle
3. choose gradle view on the left side of the android studio
4. choose android>task>signReport
5. wait some time and you will get the real sha! certificate
6. there copy and past firebase project.

if those does'nt work then check

1. if you enabled phone authenticatin from firebase auth
2. then enable android deviceCheck Api

Answer 2

Add below dependency to your build.gradle file

implementation 'androidx.browser:browser:1.3.0'

Answer 3

@Ufuk Zimmerman May the creating certificate by android>task>signReport work for you for debug but when you create signed .apk you need to use a keystore (.jks) file and you need to create SHA by the same keystore I think for this the best way to use command to get SHA.

keytool -list -v -keystore {keystore_name_with_complete_path} -alias {alias_name}

example

keytool -list -v -keystore C:\Users\name\Desktop\test.jks -alias test

Answer 4

check app/build.gradle contain following code for debug and release
