Exception: Field currentActivity or type signature not found

[ghost]

I imported the plugin and sample scene packages into my project and when I click the Sign In button of the SignInSample scene, it throws me that error.

+1, This only happens in editor tho when i build to an actual device it works without an issue

Can build, but Android doesn't show signin (activated from Start)

I ran into the same issue. In the editor I get the exception and when I run it in Android the app simply freezes. Is there a workaround?

The error occurs in GoogleSignInImpl.cs line 180:

return jc.GetStatic<UnityEngine.AndroidJavaObject>("currentActivity").GetRawObject();

Nevermind, it does work in Android. The error was somewhere else.

@henning101 What did you do to resolve the issue?

[Waterbludmouse]

Same Problem. Even it is no error in mobile ,but I don't want to waste time build and run to test something new in mobile but not editor . It's so stupid.

@henning101 What did you do to resolve the issue?

@luigimalgas "currentActivity" does not exist in the Unity editor because it is Android specific. My workaround was to just test the Google sign in the actual app and not in the editor.

@henning101 Thank you for your response. I ran into another conflict between google-sigin and firebase packages for Unity. I got it resolved to but the google-signin did not quite extend to my needs for both a desktop and app based signin solution.

I then just wrote a generic implementation from the google api. I haven't tried the work around but I have seen others saying that the workaround does work. Has anyone tried it on an AVD?

I'm having the same issue in unityHelper and it doesn't even work on andorid.

For those experiencing freezing / crashing on Android, in my case I found it was an r8 / proguard issue. I've added these lines of code to the proguard rules and it works now:

-keep class com.google.googlesignin.** { *; }
-keep class com.google.android.gms.auth.** { *; }

hi miscnz can you say that which file add this lines. i'm try adding to app_update.txt file on Proguard folder but it is not work

[cimved]

@hakanhamzaoglu For me the issue was occurring because I had R8 turned on. If you also have it turned on, you can enable custom proguard settings in Player Settings > Publishing Settings, and add rules in Assets > Plugins > Android > proguard-user

Both pc or android

[Robert-Gamer]

Having the same issue. I am not able to log in using google sign-in. Does not work on pc or on android.

[itsAshhal]

The issue is still not resolved yet, the google sdk is still 5 years old with no updates, it still throws the errors as "Exception: Field currentActivity or type signature not found"

[Omri93h]

same problem here
