Android 如何在以后的升级中添加多个索引来处理room db迁移

我试图升级room db版本，在上一个版本中，表有一个唯一的索引，当我在当前版本中添加一个索引时，它给了我以下错误

期望值：

TableInfo{name='SubmitActivityTrackerStoreOrder', columns={orderType=Column{name='orderType', type='TEXT', affinity='2', notNull=false, primaryKeyPosition=0, defaultValue='null'}, productId=Column{name='productId', type='TEXT', affinity='2', notNull=true, primaryKeyPosition=0, defaultValue='null'}, columnId=Column{name='columnId', type='INTEGER', affinity='3', notNull=false, primaryKeyPosition=1, defaultValue='null'}, distributedProductQuantity=Column{name='distributedProductQuantity', type='TEXT', affinity='2', notNull=true, primaryKeyPosition=0, defaultValue='null'}, productData=Column{name='productData', type='TEXT', affinity='2', notNull=true, primaryKeyPosition=0, defaultValue='null'}, storeId=Column{name='storeId', type='TEXT', affinity='2', notNull=true, primaryKeyPosition=0, defaultValue='null'}, userId=Column{name='userId', type='TEXT', affinity='2', notNull=true, primaryKeyPosition=0, defaultValue='null'}, productName=Column{name='productName', type='TEXT', affinity='2', notNull=true, primaryKeyPosition=0, defaultValue='null'}, productImage=Column{name='productImage', type='TEXT', affinity='2', notNull=true, primaryKeyPosition=0, defaultValue='null'}, brandId=Column{name='brandId', type='TEXT', affinity='2', notNull=false, primaryKeyPosition=0, defaultValue='null'}, promoProductQuantity=Column{name='promoProductQuantity', type='TEXT', affinity='2', notNull=true, primaryKeyPosition=0, defaultValue='null'}, activityTrackerId=Column{name='activityTrackerId', type='TEXT', affinity='2', notNull=true, primaryKeyPosition=0, defaultValue='null'}, syncStatus=Column{name='syncStatus', type='TEXT', affinity='2', notNull=true, primaryKeyPosition=0, defaultValue='null'}}, foreignKeys=[], indices=[Index{name='index_SubmitActivityTrackerStoreOrder_productId_activityTrackerId', unique=true, columns=[productId, activityTrackerId]}]}
