Use a custom content provider (which is built on top of sqlite). Many tutorials on the internet describing how to do so

Content provider is similar to core data as they both place a wrapper on sqlite

Create sqlite databse save all data u fetching from server.

SQLiteDatabase db = getWritableDatabse();

ContentValues contentValues = new ContentValues();
contentValues.put("ID", offlineData.getKey());
contentValues.put("RESPONSE_JSON", offlineData.getJson());
contentValues.put("LAST_UPDATED_TIME",
        String.valueOf(offlineData.getUpdatedTime()));
if(recordId==-1) {
    recordId = db.insert(TABLE_NAME, null, contentValues);
}else{
    recordId = db.update(TABLE_NAME, contentValues, "ID " + "="+offlineData.getKey(), null);
}
db.close();

If you mean when your app fetches the data for the first time you want to store it locally and when it fails next time you want to show locally stored data. If i am right

You can store the fetched data into MySqlite database. android Database Tutorials

and note that whenever new data is reveveid from web service update it locally. Else you will have old data in your database.
