Androidビルドで"mergeDexRelease"エラーが出る

エラー詳細

Execution failed for task ':launcher:mergeDexRelease'.
> Could not resolve all files for configuration ':launcher:releaseRuntimeClasspath'.
   > Failed to transform classes.jar (project :unityLibrary) to match attributes {artifactType=android-dex, asm-transformed-variant=NONE, com.android.build.api.attributes.AgpVersionAttr=7.1.2, com.android.build.api.attributes.BuildTypeAttr=release, com.android.build.gradle.internal.attributes.VariantAttr=release, dexing-enable-desugaring=true, dexing-is-debuggable=false, dexing-min-sdk=23, org.gradle.libraryelements=jar, org.gradle.usage=java-runtime}.

対策

1. Assets/GooglePlayGames/com.google.play.games/Editor/m2repository/com/google/games/gpgs-plugin-support/2.0.0にある srcaar 拡張子を aar へ
2. Assets/GooglePlayGames/com.google.play.games/Editor/m2repository/com/google/games/gpgs-plugin-support/2.0.0/gpgs-plugin-support-2.0.0.pom の srcaar を aar へ。

設定

Google Play GamesのAndroid Setupの設定

公式：https://firebase.google.com/docs/auth/unity/play-games?hl=ja

1. unityのplatformをAndroidにする。
2. unityメインメニューから[Window] > [Google Play Games] > [Setup] > [Android Setup] を開き、
3. Directory to save Constantの項目に、Assets/GooglePlayGamesを入れる
4. WebAppClientIdの項目に、gcp&play画面で入れた、ウェブアプリケーションのClientIdをいれる。

ProjectSettings/GooglePlayGameSettings.txt に APP_IDが入ることを確認。

ProjectSettings/GooglePlayGameSettings.txt

proj.AppId=12345678901
and.ClientId=12345678901-abcdef1234567890abcdef1234567890ab.apps.googleusercontent.com

unityのGamePlayの初期設定確認

Assets/GooglePlayGames/com.google.play.games/Runtime/Scripts/GameInfo.cs

public const string ApplicationId = "12345678901"; // Filled in automatically
public const string IosClientId = "__IOS_CLIENTID__"; // Filled in automatically
public const string WebClientId = "12345678901-abcdef1234567890abcdef1234567890ab.apps.googleusercontent.com"; // Filled in automatically
public const string NearbyConnectionServiceId = "";

上のClientIdなどが入ってることを確認

Assets/Plugins/Android/GooglePlayGamesManifest.androidlib/AndroidManifest.xml にAPP_IDが入ってること。\u003はユニコード用のもので、入っていても問題ない。

<meta-data android:name="com.google.android.gms.games.APP_ID"
            android:value="\u00312345678901" />

<meta-data android:name="com.google.android.gms.games.unityVersion"
            android:value="\u0032.0.0" />

[Window] > [Google Play Games] > [Setup]でAndroidSetupが選択できないとき

1. unityのplatformをAndroidにする。

"Error SignInRequest Sign-in failed with status code: 10"エラーが発生するとき

PlayConsoleのアップロード鍵の証明書が表示されてるか確認する。

apkを上げてなければ、署名付きのapkをupして、アップロード鍵の証明書が表示されるか確認する

PlayGame認証で、DEVELOPER_ERRORが起こるとき

エラー詳細

**** APP NOT CORRECTLY CONFIGURED TO USE GOOGLE PLAY GAME SERVICES
**** DEVELOPER_ERROR
**** This is usually caused by one of these reasons:
**** (1) Your package name and certificate fingerprint do not match
****     the client ID you registered in Developer Console.
**** (2) Your App ID was incorrectly entered.
**** (3) Your game settings have not been published and you are 
****     trying to log in with an account that is not listed as
****     a test account.
**** (4) A server auth code was requested, but an incorrect client
****     id was provided. The client id for server auth codes should
****     be the client id for the game server (not the android app).
****
**** To help you debug, here is the information about this app
**** Package name         : com.example.project1
**** Cert SHA1 fingerprint: D7:D7:D7:D7:D7:D7:D7:D7:D7:D7:D7:D7:D7:D7:D7:D7:D7:D7:D7:D7
**** App ID from manifest : 12345678901
****
**** Check that the above information matches your setup in 
**** Developer Console. Also, check that you're logging in with the
**** right account (it should be listed in the Testers section if
**** your project is not yet published).
****
**** For more information, refer to the troubleshooting guide:

GCPに登録した、ウェブアプリケーションIDと、アプリに登録したものが、同じかどうか確認する。

PlayGame認証で、"Returning an error code"が起こるとき

releaseバージョンで認証させたときに、以下エラーコードが起こる場合

*** [Play Games Plugin 2.0.0] ERROR: Returning an error code.

GCPに登録した、ウェブアプリケーションIDと、アプリに登録したものが、同じかどうか確認する。

releaseバージョンで認証させたときに、上記エラーコードが起こる。debugバージョンだと、多分、DEVELOPER_ERRORのエラーが起こる。
