Or...)* - **Google Sign-In Unity Plugin** - Hereinafter called the **plugin**. - The **pre-plugin** file from [here](https://github.com/googlesamples/unity-jar-resolver). - *(Download the Unity Package file in the root path of the source code.)* - The **plugin** and sample releases from [here](https://github.com/googlesamples/google-signin-unity). - *(Download the releases.)* - ***Import Process*** > Following [this](https://medium.com/@capcomin/unity3d-google-signin-for-android-ios-games-fd59e4b6f027). - *(If needed,)* Install the **Android Build Support**, **Android SDK & NDK Tools**, and **OpenJDK** modules of the Unity. - *(If needed,)* Remember to check whether **the paths to these modules or tools** pointed to the correct places where these internal or external things should be. - *Setting Path*: `Edit > Preferences > External Tools > Android > ...` - *(If needed(?),)* Switch the platform of Unity to **Android**. - *(If needed,)* Remove **TextMesh Pro**. - *(If needed to handle some weird exceptions; Or if this plugin is needed, it is a good attempt not to remove it.)* - *(If needed(?),)* Import the **pre-plugin**. - Import the **plugin** EXCEPT `./Parse/`. - *(If needed,)* Handle the exception of duplicated files **`Google.VersionHandler.dll`** - *(It MAY be better to delete the duplicated file in **plugin**)*. - Synchronize the **gradle files** in the project. - *Command Path*: `Assets > Play Services Resolver > Android Resolver > Resolve` and then `Assets > Play Services Resolver > Android Resolver > Force Resolve` - *Command Path*: *(alternative sometimes due to different versions maybe)* `Assets > External Dependency Manager > Android Resolver > Resolve` and then `Assets > External Dependency Manager > Android Resolver > Force Resolve` - *(If needed,)* Import the **sample scene**. - ***Web Client ID*** - The Web Client ID provided by ***GCP Project***. - This ID is needed to apply the main features of this **plugin**. - ***USE IT*** - Try to follow the provided **sample scene**. - It seems that there is no such an official document to this plugin. Maybe the **source codes** of the plugin and the **sample** help. - Or visit the official **[Google Sing-In](https://developers.google.com/identity/sign-in/web/sign-in)** website to understand the basic conceptions, maybe useful *(or not)*. ### Implement Note ***[秘](https://hackmd.io/8WnQ1K-FQYScCfvMtnFKOg)***
