Recently I've built an android app based on Firebase Phone Authentication. After publishing to Google Play, it caused error like below. "This request is missing a valid app identifier, meaning that neither safetyNet checks nor reCAPTCHA checks succeeded" When I didn't restrict app singing in google developer console, it works fine.
There are many questions and answers about this problem on stack overflow and I tried all cases. eg. This request is missing a valid app identifier, meaning that neither safetyNet checks nor reCAPTCHA checks succeeded But it's still causing the same issue. I found out safetyNet is deprecated, instead using google play integrity since last month. But I couldn't find any example code for phone auth using google play integrity. Does anybody resolve this already?
