Room 1.1.0版本.

迁移后的第一次运行时出现此错误.

如果我关闭应用程序并重新启动,它将运行良好.

@R_301_6948@初始化代码如下所示(Dagger AppModule)

@ProvIDes@Singletonfun 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;")    }  } 

该应用程序从版本2升级到版本3.
我该如何解决？

解决方法:

将版本升级到1.1.1-rc1,再也不会发生由Google自己的代码引起的这种无意义的错误,我已经在许多设备上测试了相同的场景.
