Securing SQLite and .apk

I am preparing to release my app to the Google Play Store. I would like to know what the best practice is to secure both the .apk and the embedded sqlite database. I know I can use ProGuard, but not sure if that protects the data and was wondering if it is worth considering SQL Cipher?.
Alternatives to this are encrypting the data at row level and obfuscating the code, but ideally I would like a simple solution that protects both the source code and the database.
