如何将SQLite DB从手持设备转移到可穿戴设备？

Question

I have an app with 2 modules: 1 for an hanheld and the other one is for a wearable. I have the DB on my handheld module and I need to copy it somehow to the wearable. My DB is really small, it contains only strings so it shouldn't be a problem to copy it.

At first I tried to use a shared DB for both modules (with a singelton class) but without luck, each module saw a different DB no matter what I did. My second attempt was to send it through the data layer from the handheld to the wearable but I`m not exactly sure how to do it and in addition I saw that I need to export my DB to a file each time and it seems a bit too complicated.

Please try to help me figure out what is the best solution.

Answer 1

Handheld:

1. select all rows from the table and put them into DataMap object
2. send the DataMap object using DataApi

Wearable:

1. receive the DataMap object using DataApi
2. delete all rows from the table and insert the received.
