It's due to code obfuscation, exclude your firebase code from code obfuscation. Try reading this - https://developer.android.com/studio/build/shrink-code

  • Thank you for helping me, you give me the hint, the problem solved by adding this line '-keepclassmembers' in proguard-rules – Mahdi Rida May 25 '22 at 18:01
