这是错误代码

C:\Users\huh\AndroidStudioProjects\test\app\build\generated\ap_generated_sources\debug\out\com\name\test\database\AppDatabase_Impl.java:56: error: onCreate(SupportSQLiteDatabase) in <anonymous com.droidbane.test.database.AppDatabase_Impl$1> cannot override onCreate(SupportSQLiteDatabase) in Delegate

• 您能否至少分享一下我的错误或您使用的房间代码，或者给予一个示例？*

这是我的错误代码，它引导我到这里：（应用数据库_实现. java）

@Override
  protected void onCreate(SupportSQLiteDatabase _db) {
    if (mCallbacks != null) {
      for (int _i = 0, _size = mCallbacks.size(); _i < _size; _i++) {
        mCallbacks.get(_i).onCreate(_db);
      }
    }
  }

这个错误是我造成的还是文档造成的？代码是旧的吗？我做错了什么吗？
