Hi everyone,
I was wondering how does the actual gps positioning happen in Android, is it done by the OS or by the apps themselves?
Is it possible to do the positioning fix within an app?
The reason I ask is because I'm working on a custom gps positioning algorithm as part of my research and it would be great and easy if I could test it on the phone as I work on it.
Thanks, I appreciate your help,
Marin A.
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

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.
Hi lads,
I was wondering - is there a way that Android application can acquire screen for some time exclusively?
Consider scenario:
Android broadcasts some common intent (say: wifi state changed)
There are N>1 applications which receive the intent
Each of them starts activity
User experience is awful here, activities stacks one after another (depending on order of intent delivery) and last lucky one is being displayed on the top.
Is there a way to prevent it? Someway of locking the screen just for one application exclusively for some time?
Any help welcome, thanks.

Many of you may think this is noob question and guy has no idea what he is talking about - this is not the case (at least I hope so). I am pretty sure you cannot do it using official API beside monitoring other applications activity and killing them as soon as possible so that only one (mine) is on top (not sure about legal side of this operation).
Maybe I am missing something, maybe there is a way of achieving this in other way including native coding and/or Android modification (I can talk to Samsung, they will do it for me if I am kind enough ).
Hi Guys,
I am planning to make an Android App which will act as a virtual Meditation hall, where many others would have connected to, and this App, should show me the count of the number of people that are currently logged in, it must also show me, the current Idea or Notion or say, a goal, for which the people are meditating, Now, just to clarify, in case you are wondering, In Yoga, there is a practice of Group meditation with a unified thought or unified mental state, so, I am planning to emulate this real life activity, for the Yogic practitioners, also.
Anyways, here is how i imagined it would be,
Module 1: Connect to the server
Module 2: log in
Module 3: Suspension, where the user simply keeps the app on and it will update the status of the hall, i.e. whether any new members have joined in or any has left.
Module 4: exit
Now, I must say, that the only background i have is of Flash, and I am not sure how this would help me out, but I just want to know
1) how to implement modules 1,2,3,4. i.e what is the programming elements i should use, no need for detailed explanation, just to point me out to what to study, because i am just about to start learning android programming and i need to have this app up and running ASAP.
If possible, i would also like to hear how you would segment this app idea into your own modules, if you have any advice on it.
P.S Please bear with me if i had commited any of the noobish mistakes of asking in a wrong category or asking something redundant as I am new to this and It was not intentional.
Thank you
Hi XDA!
This is my first post here. I need some guidance on making a system application that is capable of disabling a particular hardware component device. I don't know if it is possible or not, but I need a direction towards this. Even if it isn't possible, I would be grateful if anyone can guide me atleast close to this. I know making basic android applications and am interested in making apps that have a much more stronger hold on the device. Also what knowledge and experience do I need to be capable to explore this area.
tl;dr: need a direction and advice to make a hardware disabling system application
Any advice is appreciated.
Ciao!
