This is fixed in a more recent version of the GPGS plugin.

It's a 1 line fix, change Assets/PlayServicesResolver/Editor/PlayServicesResolver.cs, delete lines 96-98 and replace them with
_resolver = Activator.CreateInstance("GooglePlayServices", CurrentResolverName) as IResolver;

See the diff for an exact description of the change: googlesamples/unity-jar-resolver@63eb8ea#diff-86926bc483f4ac58a029a8a416af2ba6R96

[Lightone]

the lines 96-98 of me PlayServicesResolver look like this,i dont touch anything.

static IResolver Resolver
{
get
{
if (_resolver == null)
{
// create the latest resolver known.
_resolver = Activator.CreateInstance("GooglePlayServices", CurrentResolverName) as IResolver;
}
return _resolver;
}
}

[claywilkinson]

Hmm - do you have multiple copies of any files in that directory?

[Lightone]

Nop, only one, now is fixed i do the options Resolve clients Jars and now appear the log about the resolve when edit something in the class i have implemented the GPGS and the google play service is running fine and thanks for your help 👍 .

Great! glad you got it working.

[DilaraAlbayrak]

i've exactly the same problem, @Lightone i cannot understand your solution, can you re-explain?

[Lightone]

Click right in your asset folde space, some menu appear (look like this) and search for google play service and click and check setting and you have select background resolution enable and click on resolver client jars is your have something not update with google play some pop up appear (two options appear) keep the version and update, click in update and wait the process finish and that all, some log appear in unity console when the process completed, that all i do

[DilaraAlbayrak]

Thanks for your explanation. When i clicked resolve client jars, pop up did not show me two options, it just directly said "Resolution Complete" but it worked!
