Hello Everyone. Recently, I have developed an app using Ionic 2, the app creates Sqlite DB and feed it using web API. Everything working great through IonicView and unsigned .apk app version. But the release version of the app does NOT able to open a connection to DB, I have checked the whole functions of this version, everything working as in the unsigned version except opening the DB. Any Ideas. Thanks ---

How are you building your dev version? How are you building your release version? What is your `ionic info` and content of `package.json`? ---

My first advice would be to upgrade all the things. ionic-angular, app-scripts, angular itself, ionic-native… Can only get better and shouldn’t cause too many problems. ---

First step: Post your new `ionic info` and `packages.json`. ---

Any chance you’re attempting to access SQLite before the platform is ready? ---

No, I do check if the platform is ready. platform.ready().then(() =\> { … my code here… } ---
