房间迁移："no such table: room_table_modification_log"

Question

房间1.1.0版本。

我在迁移后的第一个运行收到此错误。

运行如果我关闭应用程序并重新启动它就很好。

ROOM: Cannot run invalidation tracker. Is the db closed?
java.lang.IllegalStateException: Cannot perform this operation because the connection pool has been closed.

数据库初始化代码如下所示（Dagger AppModule）

@Provides
@Singleton
fun provideDataBase(app: Application): AppDatabase =
  Room.databaseBuilder(app, AppDatabase::class.java, DATABASE_NAME)
      .addMigrations(MIGRATION_1_2)
      .addMigrations(MIGRATION_2_3)
      .build()

private companion object {
  const val DATABASE_NAME = "app.db"

  val MIGRATION_1_2 = object : Migration(1, 2) {
    override fun migrate(database: SupportSQLiteDatabase) {
      database.execSQL("ALTER TABLE table1 ADD COLUMN column0 TEXT;")
      database.execSQL("ALTER TABLE table2 ADD COLUMN column0 TEXT;")
    }
  }

  val MIGRATION_2_3 = object : Migration(2, 3) {
    override fun migrate(database: SupportSQLiteDatabase) {
      database.execSQL("CREATE TABLE table0 (column1 INTEGER NOT NULL, column2 TEXT NOT NULL, PRIMARY KEY(column1))")
      database.execSQL("ALTER TABLE table1 ADD COLUMN column1 TEXT;")
      database.execSQL("ALTER TABLE table1 ADD COLUMN column2 TEXT;")
      database.execSQL("ALTER TABLE table1 ADD COLUMN column3 REAL;")
      database.execSQL("ALTER TABLE table2 ADD COLUMN column1 TEXT;")
      database.execSQL("ALTER TABLE table2 ADD COLUMN column2 REAL;")
      database.execSQL("ALTER TABLE table3 ADD COLUMN column1 INTEGER DEFAULT 0;")
      database.execSQL("ALTER TABLE table3 ADD COLUMN column2 TEXT;")
    }
  }

应用程序从版本 2 升级到版本 3。我该如何解决？

Answer 1

将版本升级到 1.1.1-rc1，这种源自 Google 自己的代码的荒谬错误将不会再发生，我已经在许多设备上测试了相同的场景。

另见我的

Answer 2

我修复了这个崩溃。我的私钥类型和外键类型不相等，

设置相等类型后，不会发生崩溃

Answer 3

就我而言，当我使用 LiveData 并在创建 RoomDatabse 实例时重写 onOpen(db: SupportSQLiteDatabase) 时，我因这个错误而失败

Room.databaseBuilder(context.applicationContext, AppDatabase::class.java, DATABASE_NAME)
            .addMigrations(MIGRATION_1_2)
            .addCallback(object : Callback() {
                override fun onCreate(db: SupportSQLiteDatabase) {
                    super.onCreate(db)
                    initTypeDataFirstTime(context)
                }

                override fun onOpen(db: SupportSQLiteDatabase) {
                    super.onOpen(db)
                    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.P) {
                        db.disableWriteAheadLogging()
                    }
                }
            })
                .build()
