sqlite - Best Possible way to Store Data (Lot of Strings with Images) in android application -

-

I'm trying to create an application that will be of an eBook type (lots of theory and figures).

  • Or simple text files

    I am also very worried about the data protection. This will be a paid app, I want to secure the data and it's fast and convenient too.

    In addition to this, I thought about changing the doctor files (data) in the App Format & amp; So use the app API to access the data and display it on the Android app screen, will it be a traitorous idea? Compared to the above methods?

    Which is more secure, fast, flexible & amp; easy!

    Depending on what is more important to you - speed or security

    Speed ​​

    Definitely SQLite, it's not quite clear, but definitely the fastest way.

    Security

    Custom files that are encrypted - it will take some time for the entire file to decrypt it and display it, Ensure that the attacker will use encrypted files and without the knowledge of encryption - that data will be useless for that.

    EPUB

    If you are worried about security, you do not know how to apply DRM ... and honestly There is not a way to go.

This is what I was trying to do. You can get it Connection parameters from the DB reading source (for example Excel or a CSV file in my example) < / Li> Store the parameters in the variable Using the variable in your connection's settings. Setting Variables Create another conversion for (you can not do it in the same conversion Uses): set variables element variable: The element that reads / writes your data creates a new connection and sets the connection parameter using $ {variable name_} Note that you will need to type in the field field in the field $ {password} Also keep in mind that this can be a security problem as the

    I am trying to implement a screen-scraps application that opens a URL in which a parameter changes as it is for a loop: var data = [ '100', '101', '102', '103', '104']; (Var indexA = 0; indexA & lt; data.length; indexA ++) for {Phantom Generation ({'port': freeport}, function (pH) {ph.create page (function (page) {page.open ("http: //...++ data [index B] +" ...

Data is verified in scrap HTML and from index to array Matches. So in page 101 I scrap '101 and retrieve' and pu
