Why there are two consecutive data?
Is there any intention or unavoidable reason on the Android architecture?
Just out of curiosity...
I think it is because
The first data folder can be opened without root access,
the data folder inside it is not visible without root access.
So
one to show for guys without root access without any contents.
second for guys with root access.
haha this is android engineers personal decision, no need to know more reason

I want to create an application like "King Root" that root the android device by one click.
Is there a library or code for this?
How can I do this?
This is not a thing you can just do and if you could, it would mean that android would have a HUGE security breach, since with root access strangers could have unwanted access over the whole device, including banking information etc.
By the way: KingRoot does not work

There are 2 projects, one project is about a restaurant internal order management and the other is a food platform with multiple restaurants.
I want write into the database of the restaurant from the food ordering app without connecting my app to the restaurant project.
I can't seem to find a way to do this automatically without connecting them. a workaround could be to export the data and reimport it into the other project. in theory, you could even make a script do this for you.

(How) Is it possible to extract the sql-file from an android application on my pc? We developed an app and used it on some devices but unfortunately some of them didn't save the information on our web interface. So we need the database from three phones and typing by hand is out of the question.
Yes, depending on where it is saved you can access the .db file via the device file explorer on the right in Android Studio.
I assume it is in data/data/yourPackageName/databases
There should be .db files, but again, they could be somewhere else depending on the way you created it.

I'm a beginner in android atudio, I recently make my first app, I put in many raw resources file(txt,mp3) that is why it's size is big (~200Mo).
I want to allow user to download what he need in order to benefit my service like listen to mp3 read text.
You should carefully consider why you need this much data in your app, remove all unnecessary parts and put everything you really need into the .apk as resource.
If I find some app is downloading 200MB to my phone, I'll uninstall that immediately.

I have created an android application in which I want to add a feature for viewing ppts without he user having to download it first. As in, opening a ppt on the phone browser. Any help?
Can you elaborate better.
if what you mean is what i am thinking.
Maybe for a user to be able to view ppt files in your app.
Try using APIs, or ppt supported sdks. refer here
