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

I have barely developed anything since the BASIC days on the C64 and Amiga, and now feel inspired to create some financial applications for the Australian market - such as superannuation projections.
How hard is it to develop? A few standard calculations like you would see on a spreadsheet would work, with some graphing.
Most financial applications I have found are pretty basic and don't account for inflation in rising wages and fees, etc.
I believe I could attract at least a dollar for a well developed application for superannuation alone.
I have installed the Android 2.2 SDK and have no idea where to start. I presume this is some sort of emulated Android device I can test my applications on.
Are there any tutorials on how to get started? What's the development language?
All I need to do is create a simple text interface to input a few parameters to run some complex financial calculations on the back end.
A really sophisticated application would pull live interest rates or other data and enter that in.
Start with this:
developer.android. com/resources/tutorials/ hello-world.html
(take away the spaces, I cant post links yet )
These are all great tutorials that will walk you through the basic processes and applications/layouts. The only issue you will have is when/if you decide to go through the "Tabs View" tutorial, there are a lot of errors in the code, and I have no idea why no one have changed it, but you can PM me for the correct version.
If you want some basics on Java, just do a google search, there are a lot of great tutorials out there for beginning Java. I recommend doing this first, just so you have a good understanding of Java(which is the development language), it will *REALLY* help out. You can incorporate other languages, but for the time being, stick with Java.
Yes, the SDK comes with an emulator so that you can test your programs without having to install them on a real device. In addition to what Jimmy said (and I can't stres highly enough that you should start with the Android Developer's website and tutorials), you can go to Stack Overflow which is a programming Q&A website. People there are generally very helpful, as long as you've shown you've actually put some effort into solving your problem before you posted your question.
Fair enough... So it's basically about learning to programme for Java? How hard would it be, realistically, for someone with no application development experience?
You need a basic grasp of objected oriented design & programming, along with an understanding of the Java language. When it comes to gui aspects & all communication with other apps/data on the device, you have Android, rather than the usual Java class libraries such as awt or swing.
How hard? It's doable, imo, but will depend on aptitude. Start with Java & then add in Android when you feel like more material to get your head around.
So basically getting started requires me to learn application development like on any other platform, in OO and Java. I may as well do a course or something then. Would a few weeks doing some sort of intro course help?
I'm sure an appropriate course could be very helpful. Though I'd steer clear of those short courses claiming to turn anyone into a valuable skilled programmer in only xx weeks, if only because the tutor will probably know less than you on the subject. Better one which makes credible claims regarding its introductory nature. A couple of degree level intro modules on OO or Java should be of help.
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.
Sorry if this is the wrong place to post, but this is my first jump into android app development-
I'm *trying* to develop a cross platform gis data entry solution for editing shapefile/ geo-database polygon (or point) attributes in the field. Network connectivity can only be relied upon before going to, or upon returning from, the field. Is there an android friendly method for using a (any) type of geo-database file? Right now, I'm planning on exporting polygons to a kml/kmz or similar, and separately export the attributes to sqlite for editing. Upon return from the field, the edited sqlite rows can be used to update the (server-side) geo-database attributes.
However, I would eventually like to be able to directly edit the geometry, but am not sure if this means having to write something from scratch to read from a local geodatabase file, or if some sort of *local* android geodatabase solution already exists.
Just trying to get an idea of the initial direction I should be taking, as I have gis programing and database experience, but haven't ever done any native android development.
Any suggestions or links to related references would be appreciated!
Thanks!

I don't have any connection to that project.
I'll check it out- thanks. I also spoke with esri, and they will be releasing some android products soon, complete with apis. Certainly not ideal or open source, but probably cheaper than developing my own. Gonna keep trying to develop a simple solution for managing and edditing attributes on my own till then.

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.
Hi everybody,
So, I'm volunteering at a non profit and recently I was approached with a proposal about an app for the organization which would consist of a small questionnaire to tell people if we can help them. Something like:
o Are you between the ages of
o Do you live in
o Are you unemployed
o etc. etc.
And the radio buttons would work as check marks that depending whether these are checked or not, an if then would kick in and direct the user to another page, either proceeding instructions or a sorry, you do not meet the criteria.
I'm familiar with some coding, a little fortran, java script and php but I just have no clue how to create an app. I downloaded the developing tools from google but I'm just blank. Can someone point me on the right direction or maybe there are templates of this kind that need just a little tweaking. Any help would be greatly appreciated.
I'd suggest you creating just a web page
I have made a demo trogper.cf/surv_demo
No, that's the easy part, I'm still fresh on client side programming. What I want is an app for android.
Hello
Eclipse or Android Studio are necessary tools to develop native java apps for Android but you should have basic java (and at least OO language) notions to code it.
Get Eclipse or Android Studio.
Then...
There are loads of tutorials on the net for basic android/java programming.
For example...
mkyong.com/android/android-checkbox-example/
tutorialspoint.com/android/android_checkbox_control.htm
would get you started with your app.
you'll need to put www before the links, i'm new so not allowed to post links yet
If you want to simplify your life a little try NativeScript or Corona SDK.
