So I'm starting an android project, very new to it and to java.
But I have a knowledge in programming, especially VB.
I'm planning to create and app for certain users to see the data from a database. Is it possible without an internet connection? If not, will be a difficult task?
Where is the database? Is it online? When you say "Data Connection" do you mean Edge/4G/LTE or WiFi or Bluetooth? Your device has to connect at least once to the database in order to copy over the required data, and it depends on the database, but you might as well just copy it locally all over to the device itself.
Here are few starting points:
Internet
WiFi
Bluetooth
Database (SQL)
I also recommend getting this book for beginners (try Google-ing it, you know...) . It was very helpful for me to use it. In about a week (if you are fast like that) you can have a pretty solid experience and understanding.

Data recovery on android
I'm interested in learning how data recovery tools are typically implemented. I've searched online and have not been able to find much information on this topic, so I'm looking for someone who can provide an overview of how these applications work. Specifically, I would like to know what techniques and algorithms are commonly used to recover lost or deleted files from storage devices. Additionally, if you could recommend any resources or references for learning more about this topic or for implementing my own data recovery application, that would be very helpful. Thank you!
I am expecting that someone give me a clear insights on how this works.

I have created my website using Java Enterprise Edition (JSP/Servlets) and MySql 8 for my database. It is a typical CRUD application with a feature that let the user track the car's location.
I thought of using Flutter since it will save me time with its cross-platform capabilities but I have'nt found any documentations that will make the user login from the app to my website and fetch some data.
I'm pretty sure it is possible somehow. Otherwise is there a way to simulate my website as fast as possible without using Chrome obviously.
Read the concept of Rest APis.Simply use the api to fetch data and you can also save data through api.You need to Connect your app to your web APi.

A company asked me today that if I could develop a keylogger inside their company application which logs what their workers do in working time with their company phones. They suspect that not every employee works hard enough.
Well I know it's not ethical but I got curious whether it is at all possible? I think Android has enough security feature to make it stop an app like this. I saw some keylogger features on GitHub but they only log inside the app, not outside the other applications.
Another approach you might be able to take would be to develop a fork of the Keyboard, and force users to use that keyboard via a Device Administrator Policy. However, as previously mentioned, this might be in violation of a whole host of employee data protection laws.

I was wondering, searched a lot in google, even tho no result, how to make an actionscript program connect with another pc.
Here's a schema i made
in the first image we have two computers, and i'm searching for the other one, and i press connect
in the second image, now that we connected we share 3 pictures...
That's just an example tho ;D
Any idea how to make a connection between users?
The multiplayer connection between users i done via sockets. But for beginners, it is usually a good idea to use some ready made library or platform to make things easier.
For flash, multiplayer frameworks that exist are
SmartFoxServer
AmfPHP
Player.IO
Red5
and many more.
Have a look at Socket Programming. These are some useful links:
http://docs.oracle.com/javase/tutorial/networking/overview/networking.html
http://docs.oracle.com/javase/tutorial/networking/sockets/
http://www.tutorialspoint.com/java/java_networking.htm
Node.js using Socket.io would be a good fit for what you need. Then use the socket.io-flash lib on your ActionScript side to talk to your server.

I am a student. I need to make a application. I have built the GUI. Now I need to know how to do it?
I have heard about sql server compact, but does it work together with j2me? If not, something to solve the problem?
It will be better if you can pass me a example. If you couldn't, not worry, I just to need to know a database program for mobile (with j2me).
Could it be possible without use a database program? For example, using a text file? Or any other storage mechanism.
Appreciate any help.
In j2me you can use RMS. But you can't handle with large data. Some Third party database's also available for j2me development. You can use that API's. Also refer this existing discussion on same in this forum. And look at database connection using j2me article.
