How to retreive data from local storage of meteor based Android App

Hello Everyone.

I have a meteor based Android application.Now i want the data from local storage of Android application because am using an API to get data from meteor but from meteor side there is problem with this.userId.So without userId its of no use.So i decided to go for local storage.

Should i go for DDP implementation or there is some another way to fetch the data from the local storage.
Please help guys ASAP.
Thanx in advance to Everyone.
