(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 hope this doesnt break the site's rules:
My question is what i posted in the title:
If i use the ROOM functions in Android Studio and then test my app on a cell phone emulator, where on my computer, is the database stored?
Inside your, Android Studio go to Device File Explorer
Then go to data->data->AppPackageName->your_db
Then right-click and extract or save it to your PC and then you can view it and also perform Query using some SQLite browser

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

In my application i need to have list of images that are downloaded from whatsapp.
I am a newbie in android programing world.
please give me some guide line for it.
There you can follow some steps :
check that whether whatsapp installed or not
if installed then check in which directory it keeps its downloaded image.
if it is a separate folder & can be accessible from outside of that app then you can normally use that images.
if it downloaded its image in a common directory then then it's not possible to find out which images are downloaded by whatsapp.
Thank you.

I am hopefully going to be embarking on producing a ios or android app that shows the x read of a till from a remote location over an internet connection. My question is wether it is possible to access a text file or xcel file, take the contents of the file and pull it to the app using android and ios? I have a way to get the x read to either a xls or txt file but need to know if I will be able to access it using a ios or android app?
Apologies for the basic explanation but I am quite new to this.
Yes, it's possible.
You will have to write a server program that runs on the PC, and communicate via network sockets.
