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'm developing an application for manage security alarms and I have to work with the alarms API, an old code written in C#. The requests for disarm, arm...the alarms have to be done in Pascal (STDCALL) and I don't know how combine Android and Pascal.
Can anyone help me?
A lot of thanks.
The only way I know to execute Pascal code in Android is to compile a Free Pascal/Delphi shared library(.so) and access its interface through JNA/JNI. Of which two JNA seems to be the far less difficult option:

You can't use Android's NDK tools to build such a native library as it is only C/C++. So you need to use an external compiler.

I want to create a reddit 'novelty' account bot to better my coding/scripting skills. Currently I just want to make a simple bot that searches new or rising links on reddit and looks at the comments in each thread. If the text matches some string of characters, the bot replies with a message.
I know this is a really general question, but I'm looking for tips on which scripting/programming language to use. I mainly have experience with Java and Selenium along with R and a little bit of batch. I am willing to learn a new language (i have a lot of free time). Also the goal of the bot isn't very difficult, so even if i had to learn a new language I don't think it would be all too difficult.
Most reddit bots are made with something called PRAW. You use Python when creating something with PRAW. Python shouldn't be too hard to learn if you know Java.

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.

I'm new to programming, and I started by learning python. However, now I'm watching a lecture series online by Stanford, and they use Java.
I'm having a hard time transitioning from Python to Java. Can someone please explain how classes work in Java in contrast to functions in Python? Public vs. Private seems strange. I've also heard 'methods' and been told they are similar to functions. Links to videos or other explanations are welcomed.
I realize this question does not have any code; but we all have to start somewhere. Thanks
You may find it better to take a step back and learn the basics of Object Oriented Programming, not necessarily related to Java specifically.
Some places to get you started:
http://docs.oracle.com/javase/tutorial/java/concepts/
http://www.codeproject.com/Articles/22769/Introduction-to-Object-Oriented-Programming-Concep
http://www.youtube.com/watch?v=c5kfCH50wl0
This is just a few, though you will find many more learning material around the web.

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.
