I am working on app through Ionic framework. I'm saving the data into mobile through SQLite but user can clear data through clear data button in application info. I have to protect my application database from user.
How can I disable the same through Ionic framework.
You can't, there is no way you can make your app a system app. I recommend you move your data somewhere else (try mongoDB on mongoLab), or warn users not to delete the data. Someone has already answered this as well: How to disable the Clear Data button in Application info of Manage appliaction
