I downloaded the source code (original, not gpc), imported and tried compiling it with android studio bumblebee 2021.1.1 patch 3 to as samsung 5 on a windows 10 (64bit).

i got the following message:

'Execution failed for task ':app:processEvalDebugGoogleServices'.

File google-services.json is missing. The Google Services Plugin cannot function without it.
Searched Location:'

however the apk installed just fine!?

what should i do? i've attached the full error
