在Android上启用Safetynet设备检查API的确切步骤是什么 [英] What are the exact steps to enable safetynet device check api on Android
问题描述
我在我的android应用程序中集成了Firebase电话身份验证.它运行了将近2个月都很好，突然从2-3天后开始，我观察到了不同的行为.
I have integrated firebase phone authentication in my android app. It was working fine for almost 2 months and suddenly from 2-3 days back I am observing different behavior.
Capcha屏幕开始出现.之前我没有启用safetynet设备检查API.查看Firebase文档时，我会尝试启用Safetynet设备检查.
Capcha screen started appearing. Earlier I had not enabled safetynet device check API. Looking at firebase documentation I treid enabling safetynet device check.
由于步骤不明确，所以我不确定我是否做对了.我也不清楚Firebase和Google Cloud是如何链接的.Firebase如何知道要链接到哪个Google Cloud项目.
As the steps are not clear, I am not sure if I did it right. I am also not clear how firebase and google cloud are linked. How firebase will know which google cloud project to link to..
先前的流程是...电话验证->接收SMS->自动验证SMS，并且用户已登录.现在流程是...电话认证->出现验证码屏幕(网页类型已加载)...->一段时间后，验证码屏幕自行关闭->收到短信->使用OTP验证登录.
Earlier the flow was ... Phone authentication->receive SMS->auto verify SMS and user is logged in. Now the flow is ... Phone authentication-> Captcha screen appears (kind of web page is loaded)... -> after sometime the captcha screen closes on its own -> SMS received -> login with OTP verification.
让我知道如何避免出现验证码屏幕.我敢肯定，如果介于两者之间，就会丢失很多用户.
Let me know how to avoid the captcha screen. I am sure I will lose many users if capcha screen comes in between.
