[aerogear-dev] SQLite Store Order By and Auto Increment ID

[Daniel Passos]

Hi Thiago,

Sorry for my delay.

AeroGear does not control the id value. This is delegated to IdGenerator,
so it's your (developer) responsibility to control it.

My sugestion is, store the last id used in a SharedPreferece or use UUID
(the AeroGear DefaultIdGenator[1]).

I have added an example using SharedPreference in AeroGear Android
Cookbook[2]
