[Q] drawing/handwriting application development

Hi,
I am new in the Android development world, have not even started reviewing the coding basics, but I was wondering if someone could point me out what needs to be done to develop a drawing application (libraries, code examples, web tutorials...), and to save the screen contents as a pdf file (if possible in android environment). This is so I can have some references ready by the time I start getting involved in app development.

[Q] app needed for research project

Hi all,
for a research project at university, I am doing some studies on mobile operating systems and how they enable users (or not) to switch between applications effectively. As part of this research I am looking to do a study of usage behaviours.
In order to perform that study, I essentially would need an application that logs:
-name of application that is on the screen
-with timestamps of beginning/end of use
-(duration of use)
-emails/uploads log files at the end of the study
I have looked in the market for any relevant logging apps, but to no avail. The built in android logger itself is rediculously verbose and is of no real help either.
I was wondering if you guys know of any such application
or if you know a dev that could potentially help in creating such an app
thanks a lot

Advice on what to research and study to make app that connects to web services

Hello! overflowers? I'm a beginner android developer and I have developed several apps that use the "basics" of android and java (for college requirements)
Now, I need to develop a new project that consists of making a web app which stores the records of all students from my college and the students will be able to check their records and other information from the college from their android phones.
I have done a lot of stuff with Android but I haven't done anything incluiding web queries, pulling info from a website to display into the device, etc etc.
So I want some advice here and/or tutorials that focus on this.
also, I have some important questions: 1. Can I pull information from the actual website from my college? If so, do I need to recieve some sort of permissions?
2. In case of not being able to pull information from the actual website from my college (for any reason whatsoever, like them not giving me permissions to do this), I could create a website that imitates its behavior, I would appreciate some tutorial or guide which could help me to achieve this.
Your help is very appreciated.
Btw, excuse if I'm breaking a rule here but something is not making sense to me.. the forum title says Q&A but when I mark this as a question it says this is not Q&A. I am aware this might be moved somewhere else but I dont know where.

I would look into hosting an sqlite3 database on a server, and access it to retrieve the data from within your app.
But the problem is, by default you cannot access an online database on Android, so you'll need to add some kind of RESTful interface, the easiest way probably being a php script which will retrieve the data from the database and return it into a JSON object for example, that you can then pull from within your app.
You'll need to expose some kind of syntax from your php script so that your app can request the data for a specific user (ie row X / column Y).
There's probably a better approach, but this is what comes to my mind.

[Q] creating an android equivalent of airPcap.

i believe i could create the app relatively easily as i am a c++ programmer and would learn the language used for android providing if anyone can tell me if the wifi chip set on the Samsung galaxy s4 can write to disk. if not it would be impossible without connecting an external method of capturing and saving the packets. if anybody could direct me to the correct place for the information i need or if there is already a project underway could you provide information. would be interesting to see if it is possible with the existing wifi chip-set.

I'm not aware of any networking cards that can write directly to disk so thats really not a requirement for pcap. You are unlikely to be able to run pcap on just an android device however if you search google play for pcap you'll find the author of kismet implemented a rtl 8187 driver in userspace that runs without root, all you have to do is plug in a rtl8187 base usb wlan card and you're good to go. http://www.kismetwireless.net/android-pcap/

[Q] Sending data over wifi

I want to use the screen of android phone/tablet as a remote input device.
I want to get the position of the finger(s) and send that using udp socket to a pc/laptop.
Later I'd also like to add more input possibilities and add the option to send data (text/images) to the phone and displaying that.
I've already created a simple server that receives messages in C++ but my knowledge about java/android development revolves around the hello world program, so I'd need a lot of tips and pointers for this one.
Anyone knows about a good(detailed) tutorial about this?

Perhaps try reposting this in C++ forum? I don't know much about it and I'm sure other may be the same way, especially since we're in the Java section. Although i really like this idea!
