android - Does the _id in content providers table needs to be in sequence -

i using content providers application.the app register added user server.the server send id user.i need populate listview content providers data.can use id _id content providers table because server's id may not in sequence.

is work on non sequence id's.or need go other options

i'm not sure id comes server side. api guide:

a provider isn't required have primary key, , isn't required use _id column name of primary key if 1 present. however, if want bind data provider listview, 1 of column names has _id. requirement explained in more detail in section displaying query results.

basically, if server id unique may use it
