Androidビルドで"mergeDexRelease"エラーが出る

エラー詳細 

Execution failed for task ':launcher:mergeDexRelease'.

対策

  1. Assets/GooglePlayGames/com.google.play.games/Editor/m2repository/com/google/games/gpgs-plugin-support/2.1.0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/2.1.0/gpgs-plugin-support-2.1.0.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] を開き以下を入れる。
Directory to save Constant：Assets/GooglePlayGames
Constant class name：GPGSIds

Paste in the AndroidResources from the Play Console
<?xml version="1.0" encoding="utf-8"?>
<!--
Google Play game services IDs.
Save this file as res/values/games-ids.xml in your project.
-->
<resources>
  <!-- app_id -->
  <string name="app_id" translatable="false">[ここにAPP_IDを入れる]</string>
  <!-- package_name -->
  <string name="package_name" translatable="false">com.example.project1</string>
  <!-- event Wiped Raid -->
  <string name="event_wiped_raid" translatable="false">[ここにevent_wiped_raidをいれる]</string>
</resources>

WebAppClientId：gcp&play画面で入れた、ウェブアプリケーションのClientId

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="\u0032.1.0" />

[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:
****   http://developers.google.com/games/services/android/troubleshooting

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 2.1.0] 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。
