help me how access 2 different azure database local tables in single class in android.

i expect issue due how using initlocalstore(), in particular calling twice.

if @ code initlocalstore our quickstart serves few functions:

  1. creating sqlitelocalstore
  2. defining table on store
  3. initializing sync context store

you should create 1 sqlitelocalstore, define many local tables need on it, , initialize sync context. i've demonstrated code below.

mobileservicesynccontext synccontext = mclient.getsynccontext();  if (synccontext.isinitialized())     return null;  sqlitelocalstore localstore = new sqlitelocalstore(mclient.getcontext(), "offlinestore", null, 1);  map<string, columndatatype> tabledefinition = new hashmap<string, columndatatype>(); tabledefinition.put("id", columndatatype.string); tabledefinition.put("text", columndatatype.string); tabledefinition.put("complete", columndatatype.boolean);  localstore.definetable("todoitem", tabledefinition);  map<string, columndatatype> nametabledefinition = new hashmap<string, columndatatype>(); nametabledefinition.put("id", columndatatype.string); nametabledefinition.put("name", columndatatype.string);  localstore.definetable("nametable", nametabledefinition);  simplesynchandler handler = new simplesynchandler();  synccontext.initialize(localstore, handler).get();
