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

No, the closest I have is "Task Manager".

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.

I was hoping there is a way to avoid using apps...
Ok, I suppose it opens another question which I thought about creating a new thread for, but if the opportunity already arose...
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.

I just wanted to note that after spending some time here in the forum( http://forum.xda-developers.com/android/apps-games/ ) looking for some intresting picks, I haven't actually encountered much comments from people that actually went over the code... so I'm a bit bummed out. :silly: :laugh:

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.
Hi all,
We are looking at releasing a new Android device, and have a few ideas for modifying the Android platform for this release, but we are having a hard time fulfilling these ideas. The product will be using OS4.2. I have copied details below for any guidance or advise:
1) Removing the App overview button. We want to remove the button on the home page that is selected to open the App overview page. How can we achieve this?
2) Automatic WiFi selection. It would be beneficial to the product to have the WiFi only on when in certain Apps (all Apps will be preinstalled to the device). If it is any easier, we could also have the WiFi go off automatically in certain devices. Preferably the former, but if one is easier than the other, we don't mind.
There are other modifications we will be undertaking, however these have been achieved. If someone could provide assistance with this, that would be great.
DJC
Is there anyone that can assist with this?
Starting with Android "L" , apps can no longer get the recently launched apps:
https://developer.android.com/preview/api-overview.html#Behaviors
The documentation (not the one on the internet, as it's still not updated ) says:
This method is deprecated.
As of L, this method is no longer available to third party applications: as the introduction of document-centric recents means it can leak personal information to the caller. For backwards compatibility, it will still return a small subset of its data: at least the caller's own tasks (though see getAppTasks() for the correct supported way to retrieve that information), and possibly some other tasks such as home that are known to not be sensitive.

Instead, they only get a list of apps that the current app has launched.
Is there a way to overcome this? Perhaps with root?
I ask this since I've recently added this feature for my app (allowing to sort apps by recently launched), and sadly it doesn't work as I made it...
Maybe I can get when the files of the apps (those that are used for launching them) were recently used? But this is just like checking the list of running processes, no?
Hello developers, best regards from Venezuela.
This question will be long because I am providing a lot of detail, so this question is as clear as possible.
Brief introduction.
I have created an app that runs on Android devices, this app allows you to share files between devices that are connected to the same WI-FI network. but with a different methodology to that used by apps that are intended to fulfill this same purpose.
On the device where my app is running (which we will named device one), a url similar to http://192.168.1.102:7898 is generated, and said url must be entered in a web browser installed on the device with which you want to share the files (which we will named device two).
The main purpose is to offer a way to share files between devices, using WI-FI. without the need for device two, my app has to be installed.
You can find more information in https://labs.xda-developers.com/store/app/com.tecnoelias.ipfiles
...
So far everything works fine. But, it is annoying that every time someone wants to share files using my app, on device two, they have to enter the url described above. keeping in mind that said url will change as the WI-FI router decides, and therefore, you should not use shortcuts to the url (bookmarks or navigation history).
Having said all this, the following question arises.
Is there a way to get device two to access that url without having to type it manually by the user?
To accomplish this, three ideas occurred to me.
1: Generate a QR code in the app. but this requires that on device two, an additional app is installed that can read QR codes. which violates my purpose.
2: Implement in the app, a mechanism that allows you to find other devices that my app is working on, and in this way, interact with those devices (through my app, similar to how other file transfer apps do). This is a good idea, but it nevertheless requires that my app be installed on both devices.
3: My third idea and the one I would like to implement is the following:
On device one, it will open my app and then activate it.
When the app is activated, the app will search for other devices that are connected to the same WI-FI network, until it finds device two.
If successful, a SOMEWHAT will be sent programmatically to the device two, that SOMEWHAT can be, a message, a bit, a data packet, or anything else that helps to realize this idea .
After device two receives that SOMEWHAT, it will show a notification or a pop-up window, which will allow access to the url generated in my app (on device one).
Consider two things. 1: Additional app MUST NOT be installed on device two. and 2: Because device two can be running any operating system, the SOMEWHAT will be a different mechanism for each operating system, (operating systems can be, Android, IOS, BlackBerry, Symbian, Windows Phone, Windows, Linux, Mac, among others).
If for example, device two, runs Android 10 (not rooted), and has the most common applications installed, which can be: WhatsApp, Facebook Messeinger, Google Play Services, other Google apps, and system applications.
My thought is that you should be able to use one of those apps, to receive the url, and after clicking on that url, the web browser will open, and then it will load the corresponding webpage (which in this case, is to access the files shared by device one, through my app).
Any idea?
You can give me your opinion, or you can just tell me that this can't be accomplished.
Any response or suggestion are appreciated.
The Android operating system was first released by Google in 2008. It's an open-source software platform that allows many applications to run on various devices while sharing data across them via cloud computing services.
And your point is what exactly? Looks like you copied the first two lines on the history of android off of an article.
