How to migrate app using sqlite database to Google Cloud. Wants to use (CRUD) all operations on data

I got an app which stores nearly 3 MB data in sqlite. Its working all good but sqlite stores data in user's device which increase size of the app.

I am using SQLiteOpenHelper,SQLiteDatabase classes to do CRUD(Create,Retrieve,Update,Delete) operations on data.

Creating tables and inserting data (int,string) in it.

Fetching required data using below command.

cursor = db.rawQuery("SELECT * FROM "+ DbConstants.table_name,null);

Development Environment:

Ubuntu 12.04

Android Studio

Java

I am wondering if I could save/insert data in Google's Cloud and do the operations like select specific column from table or delete data from table and so on which I am currently doing in app.

Will it cost me?

Please give me the useful link or any sample app which can do all CRUD operations on data stored in cloud.

Thanks for your valuable time!
