Question

我正在为Godot Engine开发一个模块，它叫做godot-android。您可以找到this module here。该模块通过SnapshotClient使用Google Drive API将游戏保存在Google Drive中。

由于我在今年早些时候发布的一款Android游戏中使用了该模块，因此我收到了一封关于Google Drive Android API弃用的电子邮件，内容是我的应用程序使用了Google Drive不推荐使用的API。

因此，我已经开始重新阅读Google Play Games Services documentation for android，但是他们没有更新文档。然后，花了几个小时在Stack-overflow / github migration guide上查找如何迁移SnapshotClient，我才碰壁。

我的第一步是将模块的所有依赖项升级到最新版本，进行编译，看看有什么问题：

  com.google.firebase:firebase-core:16.0.6
  com.google.firebase:firebase-auth:16.1.0
  com.google.firebase:firebase-invites:16.0.6
  com.google.firebase:firebase-messaging:17.3.4
  com.google.firebase:firebase-appindexing:17.1.0
  com.google.android.gms:play-services-auth:16.0.1
  com.google.android.gms:play-services-games:16.0.0
  com.google.android.gms:play-services-drive:16.0.0
  com.google.apis:google-api-services-drive:v3-rev136-1.25.0

我很高兴看到一切正常。第2步，更改用于访问Google Drive API的代码：

  public GoogleAuthentication(Activity p_activity) {
    activity = p_activity;

    String webclientId = activity.getString(R.string.default_web_client_id);
    GoogleSignInOptions options = new GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_GAMES_SIGN_IN)
    .requestIdToken(webclientId)
    // Since we are using SavedGames, we need to add the SCOPE_APPFOLDER to access Google Drive.
    .requestScopes(new Scope(DriveScopes.DRIVE))
    .requestScopes(new Scope(DriveScopes.DRIVE_FILE))
    .requestScopes(new Scope(DriveScopes.DRIVE_APPDATA))
    .build();

    mGoogleApiClient = new GoogleApiClient.Builder(activity)
    .addApi(Games.API)
    .addScope(Games.SCOPE_GAMES)
    .addApi(Auth.GOOGLE_SIGN_IN_API, options)
    .setGravityForPopups(Gravity.TOP | Gravity.CENTER_HORIZONTAL)
    .setViewForPopups(activity.getWindow().getDecorView().findViewById(android.R.id.content))
    .build();

    mAuth = FirebaseAuth.getInstance();
  }

所以，游戏开始了，我弹出登录窗口询问作用域（正确的作用域），单击授权，然后我无权访问我的保存游戏。亚行logcat：

发现了根本问题，范围不正确：

public GoogleAuthentication(Activity p_activity) {
activity = p_activity;

String webclientId = activity.getString(R.string.default_web_client_id);
GoogleSignInOptions options = new GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_GAMES_SIGN_IN)
.requestIdToken(webclientId)
// Since we are using SavedGames, we need to add the SCOPE_APPFOLDER to access Google Drive.
.requestScopes(new Scope(DriveScopes.DRIVE_FILE))
.requestScopes(new Scope(DriveScopes.DRIVE_APPDATA))
.build();

mGoogleApiClient = new GoogleApiClient.Builder(activity)
.addApi(Games.API)
.addScope(Games.SCOPE_GAMES)
.addApi(Auth.GOOGLE_SIGN_IN_API, options)
.setGravityForPopups(Gravity.TOP | Gravity.CENTER_HORIZONTAL)
.setViewForPopups(activity.getWindow().getDecorView().findViewById(android.R.id.content))
.build();

mAuth = FirebaseAuth.getInstance();
}

这段代码很好用，我更新了github模块，可以看看at the commit。

不建议使用Google Play游戏服务和Google Drive API
