Hi you all!
I don't know if I'm in the right section here, of if I'm allowed to do it, but I have a question: where|how can I find or submit an App development request?
In other words: I`m looking for someone (developer) that can build a specific App for me. I have a small budget for it, and I would love to hear from any one interested.
Below is the basic description of the work.
At first, I'll try to explain the context of what I'm looking for.
I'm director of a Pathfinder Club, also knows as Pfadfinder (German), Desbravadores (Portuguese) or Conquistadores (Spanish). We are an organization similar to Scouts, that work with children of different ages.
We meet every week to develop activities related to nature, physical skills, social works and so on.
What I need is an app for large-screen Android devices, where one can check and mark the member's presence on a specific day and the activities (pre-defined) that he has accomplished on that day. Each activity, such as the presence, must be recognized as Points, which need to be summed up for an entire year. At the end of the year, we can know who has the higher presence rate, and who has performed the most number of activities during the year.
An Excel spreadsheet has done the trick for me for some years, but I am willing to improve this system by means of a mobile device, where I can check and assign points on the go.
I guess, it would require a database with the names of each member (I must be able to add members during the year), and a interface containing the names of each members on the left (like in a spreadsheet), and different columns to the right, each one referring to a different criteria (presence, required materials along, if he has made the required activity during the previous weeks, etc). When I click on a specific criteria, a small windows should pop-up, revealing the points that I will assign to the member.
For example, on the presence case, if the members is present, he gets 10 points. If he is present, but arrived late, he get 5 points. If he is not present, he gets 0 points.
The most important: these points need to be exportable to excel, so I can work with them at the end of the year. I supposed it should be simpler than creating a fancy graphic interface on the app for that.
I'm actually from Brazil, but there would be no problem if the the app is developed in English.
This can be easily done with basic php and html. Is there a reason you are set on Android?

Hi, m.ark!
Until now I have worked with Excel spreadsheets, and it works just fine.
I'm willing to have an Android app because then I can assign these points easily on the go, with a nice friendly interface that doesn't require typing the points.
If your question was about Android versus other mobile OS, then the answer is based on the price and availability of Android tablets. And because I already own one.

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.
Hi all
I am developing an app in which I would like to allow user-generated content. Specifically, this will be a remote control application, and I would like people to be able to add custom layouts, capable of sending "events" through the app, but I am not sure how to do so.
There are a couple of ways I have been looking at. The first is using a WebView so that this content can be developed in HTML. This would be nice and easy from their point of view, but it does have it's downsides, especially where security is concerned. If I was to do this, I would want to bind a "send" Javascript interface to my app, but disallow any other Javascript (I do not, for example, want it to be able to relay the button presses to some other place). I'm not sure exactly how I could do this.
The second way I can see would be to use an XML file and build up the layout from that. Here, the only way I could see it to parse the XML file and programatically build the layout. This seems a lot of work, and I would rather avoid that.
A third way would be to import a layout purely as an image plus an XML file describing hot-spots for triggering events. This seems to have too many limitations.
The final option is to expose an interface to other apps, and allow users to build separate applications which hook in to provide these layouts. This seems a terrible approach for such a simple objective.
So, does anyone know of a simple way to do what I am after, or any comments on the options listed above? Has anyone done anything similar, or know of an open-source project which acheives something similar?
Thanks in advance
Hey,
When I turned on my phone the RAM it was taking was 300 MB, after a days use it is now 500MB (even after pressing 'clear RAM' button).
I've entered Settings->apps->running and it shows only two small things (the keyboard and some weather widget) which combined take only 20 MB.
So what is the rest of the memory is beign allocated for?
Thank you.
Does your rom have Usage Manager in the app drawer?

Here is the path to all your applications.
Settings -> Apps --> Swipe left until the menu Running --> On top you see the description "Show cached processes", klick on it --> now you see the rest of the running applications

Thank you, indeed I see some more RAM guzzlers, but It seems like they make up most of the addition but not all of it ... plus funny thing, when I try to close everything (in 'running' and 'cache) and I reenter- here it is there again...
1) Can I see all of the elements that take up my ram (the system as well)?
2) Can I close them properly?
Thank you very much.
PS. Is there some comfortable way to jump between apps? Like in the Iphone where by pressing the 'Home' button will show you a bar with a row of icons of the currently active processes....
For your PS question, it's a long press on the Home button (below the GS3 screen).

The closest app I'm running to that option is Android Tuner Free. I got it for its storage optimization functions.
The busy interface has a learning curve, but it is a comprehensive & poweful app. I recommend Advanced mode & the One Click home screen.
For what you want, see both the Tasks & Kill All tiles. The first is a Task Mgr., the second is a quick 1 click. The app can teach a lot about what runs & why. It also offers a lot of fine control.
I also use the root app Startup Manager which is self explanatory & efficient.

How do you actually know if you can trust an app?
I'm kinda new to android and I'm much more used to the opennes of windows, also I'm pretty paranoid (a cellphone contains information 100 times more sensitive than a PC (At least my PC is like that)). I look at the permissions every app want to have and I'm simply aghast, I know of the logic behind those requests (at least for most of those I've seen) but I have zero transparency over what actions the app takes.
That really stress me a great deal...

Digital Privacy
Well it certainly stresses the last remaining fiber of your privacy. I just watched the latest "60 Minutes Overtime" piece on data brokers framing this as a lifestyle issue. Step back from the small screen & consider that your actions on board the PC have a ripple effect on your smartphone. "NAI Opt out" & "Disconnect software" are useful PC search words.
Where it Went
I rarely hear from a tech guru or even a lawyer who can decipher a EULA, TOS or Privacy agreement they didn't author themselves; yet online, we are steeped in the cumulative concessions we have accepted from them and the affiliates and partners they enable for.
The Biggest Brother?
Google is a data harvester, not a broker. They are the custodians of much of our imprint online across all platforms. check your settings accordingly; within each Google service / app/ platform you use and adjust them to taste. Know, for example, that persistent login to Gmail will append any collocated G-Search activity to your G profile if Web Data | Web History remains on. I read recently that simply joining Plus has a similar but more comprehensive effect by default, by unifying the G tracking across your entire electronic imprint.
Android Permissions
Yes. The most invasive part of Android is its permissions free for all. They are demands, not requests that each app poses. The logic is sometimes one sided and self serving to the developers at our disadvantage. What can we do?
1. Know something about your developer. XDA membership in an app developer helps define their role in a community. Check their website, reviews, accessibility, postings etc.
2. Consider lower permission alternative apps listed in the play store.
3. For each app you review in the Play Store, (have you checked play store settings yet?) assess its longevity in the marketplace to decide if you are willing to be an early adopter.
4. Resist resorting to apps to broker built-in functions your system already has. Learn your OS.
5. Weigh the logic of each permission demanded, based on risk / reward and your intended uses. Example: On my phone Google search leads the field with 59 permissions. App Permisssions by FSecure is in the low end group with zero. How do I know? App Permissions. What can I do? More on that later.
6. Debloat. I have frozen over 60 apps/services/processes using a combination of tools ranging from built in (no root) Application Management to Startup Manager and the App Quarantine app.
7. Don't be lazy about toggling settings as needed. One stock default has the GPS always enabled which may not be necessary for you.
8. Learn about the types of location services in your OS. Check location settings in affected apps and consider toggling location services as needed. Apps will prompt if the needed service is off when you use them.
9. Review your synch settings. Mine are off on the OS. I use a 3rd party mail app and manually back up contacts using Super Backup when needed.
10. Review background data settings. they are visible in Settings / Data usage, by selecting Mobile Data, and scrolling to the list of apps to tap through each and set Restrict background data if appropriate. It saves battery by reducing tower hunting and focuses you on which apps pose the highest demands.
I promised more. Learn about App Ops if you haven't. I have the luxury of running a 4.3 version that supports it so I can use a client app to filter and toggle various permissions on a per app basis. There are other, and perhaps more thorough approaches to this but I'm staying with this one for now.

Thank you very much for the comprehensive reply!
Indeed some of the things here are common sense but some were fairly new to me, like the close contact you are suggesting with the developer.
I have to ask though, what reviews are you reffering to? the ones in the app market or the ones on here? Also, from what I have seen in the play market, all of the reviews are about functionality but no one actualy checks the veracity of the code.
Like for instance some song recognition&download software that requires internet access permission (makes sense) and SD card access permission (also makes sense), but besides doing what it does (in a splendid manner, leaving tons of happy customers) it also steals your Whatsapp chat logs (just read an article about that breach 10 mins ago)...
How can people catch on that (otherwise the app will linger for 2 years, giving you the impression you're not an early adopter)?
Hrmph, you have given some very sound advice which I obviously intend to follow through and for that I thank you. However it seems to me like the underlying foundation is still trust in the publisher (not to abuse the permissions you had to enable for functionality sake), and the trust should stem from how well the author presents itself to the community. I suppose it is the nature of the beast, it is just that if I were to sneakily attack someone I would make sure to present myself in th best way possible .
thx.
PS. my version is 4.1 but I'll see what I can do about Appops.
P.P.S I just searched for "Tasks" on google market and all I see is an organizer. Did you mean "Task Killer"?

Both sources really. There's no hard & fast divide as to what aspect reviewers might respond to at either venue. More often, Play Store reviews have alerted me when my device or my Android version gets poor results from an app. Granted code integrity issues are raised more frequently at XDA.

Interesting example. I will look for the article. I wonder if the app declared that permission in their Play Store disclosure. If not, it challenged Google's policing system. I read somewhere that SELinux in newer ROMs, set to "Enforcing" brokers applicable policies from each host domain and also restricts apps from exceeding their declared permissions. (See also my note on 4.3+ below)

You're welcome! Placing that trust is ultimately a leap of faith, so we ask ourselves:
Does my configuration already offer this function at the OS or existing app level?
Can I justify each declared permission here?
Is there a less invasive equivalent to this app?
Have I gone over the settings thoroughly once installed?
What does my installed anti-virus say about this?
Do I need this to auto launch or only on demand?
Is it using excessive data or uptime as I monitor?
Am I getting all the Android security I could be with my current rom image?
You get the picture. Common sense, best practices & due diligence can go a long way toward closing the security gap.
PS. my version is 4.1 but I'll see what I can do about Appops.
Google only exposed it (to client apps like App Ops Starter) in 4.3 & 4.4.0, before & after that I believe an Xposed Framework module is the main alternative.

The "Tasks & Kill All tiles" I referred to appear on Android Tuner Free's One Click advanced mode home screen. BTW certain apps on my phone are "frozen" when not in use.
I forgot to mention. 4.3 I'm running is on the 4.1.2 bootloader, completely avoiding lopsided knox security. I hope I didn't appear to recommend the OTA update. That's a personal choice.

You're welcome. To be fair, most times I've seen postings by people who background checked code it was in rom threads, or over root exploits or security apps. In most other cases due diligence is our best defense.
Does anyone know if there is a Guide/CheatSheet for Security Testing Apps on Android?
I am a software tester and whilst I know my way around security testing for the web, I'm looking for a jump start in Security Testing for Android. Just the basics really, things like how to manipulate text fields, cause buffer overruns etc in Apps.
An example case would be an app which we are developing that allows a user to input free text. I want to be able to prove the point that we need to sanitise the user's input here, so ideally, I'd like to know of a string that I can enter, which will cause an undesired effect on the page which displays the user's input.
eg, In a web page, I enter "<IMG SRC=javascript:alert('Sanitise User Input')>" and an alert is fired on displaying that input.
Like I say, I know my way around this type of thing for the web, but I'm not an Android Dev and I don't know how to manipulate the code with my input.
So, Does anyone have any pointers/source of info/ideas?
Thanks Folks,
