Screen Capacitance Value Reading - C++ or Other Android Development Languages

Hi Everybody,
I have a Toshiba AT270 (7.7", Android 4.0.3) and I want to develop a very simple application to determine the distance of users finger from the screen (a couple of mm's or 1 cm at top). In short terms ; I want to be able to read the capacitive reading of each touch-cell as numerical value not as binary like user pressed-or-not. In theory this should be possible but I don't know if the API has such a feature or not. I can dive deeper than API if one suggests a hacky workaround for reading this.
I wanted to have experienced users opinions before starting to read some docs and API.
Peace
y.

Yeah, it is possible. But seems you are trying to achieve it with Mono Droid. I exactly don't know if it supports the feature or you will have to do a bind. Btw I prefer you to search on Google and as you can see not many users wandering here, though only few interested in mono Droid.
Sorry for being ot and not helping.
Good luck

[Q] is there an app that checks all installed or purchased apps for ICS compatibilty?

maybe either through API level, or by querying market info
Reason: i want to check on GB before I upgrade to ICS, which apps will not work.
don't know if relevant but it is for SGS II
Thx in advance
repost from here as nobody could really answer my question
can't believe I'm the only one with that issue
maybe an idea for a dev? would be willing to pay for that ;-)
I don't see why this can't be done:
-http://stackoverflow.com/questions/2695746/how-to-get-a-list-of-installed-android-applications-and-pick-one-to-run
-http://developer.android.com/reference/android/content/pm/PackageManager.html
-http://developer.android.com/reference/android/content/Context.html#getApplicationInfo()
I haven't thought through the problem just yet, but its seems to be doable. If you don't find an app soon, I will start working on a script that does it and, if successful, a proper, free software app. I am hoping the available methods won't require something as stupid as launching each app fully. But again, I haven't thought it through. Thanks for the idea btw.
EDIT:
Made a little more effort
https://groups.google.com/forum/?hl=en&fromgroups#!topic/android-developers/dXLACRIizKc
I will work on something this weekend and get back with y'all.
EDIT 2:
So it looks like I would need maxSdkVersion which I don't find in the API. Furthermore, it is strongly suggested that one not use maxSdkVersion when building an app so that doesn't sound all that useful. I have received another, much more complicated suggestion that may do what I want, but I will have to look hard at it. Looks like I'm going nowhere in my effort. Always open to suggestions. More to come later this weekend.
I'm not the sharpest tool in the shed, but I thought this was mostly a straightforward task using the API's exposure to AndroidManifest.xml. As per my previously posted link to an Android Developers discussion on the topic, my approach is dead in the water as far as I can see. I did try to find an answer though to the best of my limited ability. If anyone has or ever solves this problem (I consider it a problem) I would hope they find the this thread.
Thanks for the learning experience. I give up.
Most older apps will work fine on ICS, its pretty backwards compatible. If the app uses legacy menus the button will appear in the old lower left hand corner location instead of the upper right hand corner like apps written for ICS.
i'm no dev so bear with me if i write stupid stuff
one likely but not very promising sounding way might be to use android:targetSdkVersion as "As Android evolves with each new version, some behaviors and even appearances might change. However, if the API level of the platform is higher than the version declared by your app's targetSdkVersion, the system may enable compatibility behaviors to ensure that your app continues to work the way you expect. You can disable such compatibility behaviors by specifying targetSdkVersion to match the API level of the platform on which it's running. For example, setting this value to "11" or higher allows the system to apply a new default theme (Holo) to your app when running on Android 3.0 or higher and also disables screen compatibility mode when running on larger screens (because support for API level 11 implicitly supports larger screens)."
question though is how many apps actually use this?
However after having read this re android:maxSdkVersion "Warning: Declaring this attribute is not recommended. First, there is no need to set the attribute as means of blocking deployment of your application onto new versions of the Android platform as they are released. By design, new versions of the platform are fully backward-compatible. Your application should work properly on new versions, provided it uses only standard APIs and follows development best practices. Second, note that in some cases, declaring the attribute can result in your application being removed from users' devices after a system update to a higher API Level. Most devices on which your application is likely to be installed will receive periodic system updates over the air, so you should consider their effect on your application before setting this attribute." (taking from here) i now don't know how important my op is, but then why do all app devs release new versions "fixing things" for ICS?
One pretty significant example which actually currently will prevent my phone from getting ICS for now is that the subsonic app in the current version produces stuttering when playing audio while downloading (problem description here).
Isn't there any way to instead of searching the phone searching google play/android market instead?

Here's a list of some working games/apps for ICS
Theoretically an Android app (or a combo of say App Engine and Android) could find your installed apps, seacrh Play for said apps and then scrape the page for relevant information. Doesn't sound to hard, but I didn't think about too hard either. Perhaps I will check out what useful info is on Play and how feasible scraping its markup will be. I will get back at y'all if I do.

[Q] Wi-fi class question

Hello fellow developers nice to meet you!
I've started studying java + android fundamendals in order to create a couple apps i have in mind but i came across something i would like to ask you.
My application entails that some information will be transfered over wifi or bluetooth between two phones in close distance.
What i would like to ask you is this; will i be able to fill a couple TextViews and ImageViews with strings and images respectively?
I prefer using WiFi for the longer distance but is that feasible?
Can you give me a clue as to where i start? i dont need any code just some references..
Thanks in advance!

AndriodOAP Project

Hi all
This is my thread for an ongoing project im working on called AndroidOAP
OAP is not Owesome Android Project, lol
This is Andriod Old Age Pensioner!
But WAIT!! This may have many applications to other areas in the caring community!
Background
My mum is 75 and has early stage altzimers. I have noticed a lapes of memory, eyesight and hearing. I have also just got her a 10" rk3066 4.1 tab for xmas.
The aim of this is to help her keep in touch with family and friends (social networking), keep up to date on the weather/news (she loves it), keep her mind active (games).
Aim of Project
This project has a few aims, guided by anyone who wants to contribute. some of which are :
BASIC
- Creating a simple UI that is easy for pensioners/handicapped people to use
- Identifying simple to use apps that perform complex tasks
- Utilise the accessibility capabilities of android specifically for the users needs
- Monitor the device remotely
- Monitor the users interactions and provide alerts (IE medication, doctors apointments, etc)
EXTRA
- Create a working rom that can be installed on devices that can be given to the target audience (OAPs, disables, etc)
- Obtain ongoing support for this project
This will probably not interest most of you but anyone willing to contribute to this nobell cause will be very appreciated
Please get in touch with any ideas
Thanks for your time

If I read this correctly, you want to develop an OS based on Android, but one that is extremely simple to use? All I know is that this would be an extremely time consuming project, probably half a year at the least, because you'd have to remove tons of drawables (images and stuff that is rendered) and code, and add in many more. It would be much easier to just install a launcher with big icons, change the system font size to the largest possible, perhaps use some accessibility settings, and debloat the tablet to the max.
Has your mother ever used electronic gadgets before? I forget the saying, but it's something like you can't teach an old dog new tricks. Considering that these types of electronics didn't exist during older peoples' generations, it'll be significantly harder to get them accustomed to such things. I don't know if I'm stereotyping or not, but it may be increasingly difficult to teach her how to use Android because she has Alzheimers. I'm not saying it's not worth a try though. As long as she doesn't feel overwhelmed or frustrated, I'd say to definitely try it out for a while and see how it goes. Happy holidays and have a happy new year. I hope your gift does good for you all.

Thanks for the input dude, but, I think your over complicating things. A custom rom doesnt mean rebuilding it from the ground up! The aim is to find the most user friendly apps and the best settings and then create a rom around that. no need for new icons, etc.
Just to let you know, even though my mum is 75 she has been a nurse all her life so is well versed on using computers (hell, she brought me up and im a developer, lol). Touching icons on a screen will be no problem for her, altzimers or not. To be fair, you are stereotyping and its pretty sad
Regardless of the support I will continue with this as its a personal project that I will persue. I was just after any help I could get, not negativity.
Have a nice day

Hi @Cass1977, I see your project as a great initiative to encourage older people to use technology. Although this project might be huge (and I don't have the tablet to test), I might be able to just provide suggestions for your project.
In the Basic section:
Simple UI: It should be easy, due to the fact that many launchers today are user-friendly and easy to use.
Simple to use apps that perform complex stuff: do give some examples.
accessibility capabilities: I don't know of much apps for that (there could be some in the play store) but once we attract the attention of some developers, we can start rolling.
Monitor the device remotely: what do u mean exactly?
Isn't monitor the user's interaction same as the point above? Correct me if I'm wrong.
More suggestions:
Create some tutorials for some complicated apps.
Better colour profile.
Less bright screen=less strain to the eye in low light conditions.
Bigger font=less strain to the eye.
More suggestions will come as I think of them.
Smack that thanks button if I helped!

Good advice, but I feel too many launchers have too many options. the main thing the user needs is simple to access apps. Maybe large icons, etc.My mum likes her news and weather too so simple widgets may help with things like that (A lot are provided with the apps).
TTS will be required too (Text to speech). Maybe an app that will speak highlighted words? Probably have to be built?

By the way, By 'Monitor the device remotly' I mean basically the same thing I have with my kids tabs. Screen Time (MASSIVE RESPECT TO THIS APP!!!) It monitors what my kids do on their tab and allows me to lock it at certain times and give them chores to earn rewards. NOT the same thing we need here, but, thats the kind of monitoring im thinking. Monitoring medication (pop up reminder and if its not used a remote notification)
Any more ideas you have then let me know, Many thanks for your input

I can help test launchers according to what u want and report back. Widgets are easy. (Most news apps has widgets.) There may be some apps for TTS designed for this but it's rare (if not none). (TTS apps are extremely complicated) yea, we might need to build it. (Build from Google voice search, possibility)
OK... I'll have to search it up on Google. (We may have to build from another app...) we can build from Screen Time (add some features into it, we could ask Screen Time's developer for help!)
P.S. I think editing a system file can increase the maximum volume of the sound...

Best choice for an app that requires multiple sensor inputs.

Hi there, I am fairly new to developing apps. Have some experience in coding however looking to find out from experienced users suggestions for the best route to take and use to code and develop a prototype app that requires constant input from sensors including body temp and monitor, flagging cautions/warning when parameters are passed. Sorry if bit vague. There is so much out there but after something that is better for beginner to app building that i can then emulate on until tech is available.
Thanks For Reading!

ISO A programmer to create a specialized application

Hello all,
I am low vision legally blind and I am looking for a programmer to create an application. Basically a camera application that can be controlled via the devices hardware buttons, Bluetooth mouse and voice command.
Basically this NuEyes running as an application on the ODG R7 Smartglasses rather than the OS overlay (i think that's the term) that is currently used.
EDIT 20150627: I thought I would add a little more information in here to try and make my stumbling rambles clear. What I am basically looking for is something with the features of Visor that can be controlled using the unused option buttons on the R7's finger mouse and optimally respond to basic voice commands such as "change filter" to rotate through the 3 visual settigns as well as "increase" and "decrease" for magnification. I really love the A Better Camera style interface and would love to include a night vision setting like the one it has as this would be very useful in low light situations to help my night blindness. Please let me know if this is possible, I really need the help coming up with an alternate solution to the extremely expensive NuEyes software package. /EDIT
Being a complete novice I would like to know what would be involved in this application. What would the programmer require from ODG, framework, sample code, ext, and what kind of costs would I be looking at for the initial application and maintenance.
The reason I am asking is though I believe companies have a right to make profits and recoup R&D costs is that the NuEyes system costs about $6000, that works about to about $2K wholesale for the glasses and $4K for the software. I"m just so frustrated by how much every piece of adaptive tech for the blind costs. Every time one of us needs a piece of tech we have to sell our souls to the devil to get it.
If this isn't the correct forum to post this request in please let me know of a more appropriate location. Thank you.
Updated with clarification of project goal.
