Keeping Apps Running in the Background

Hi, I've been looking for a way to keep apps open/running in the background so that even if I switch to another application the backgrounded app is still running as it would if it were in the foreground. A good example of this is Backgrounder for iOS, except I require the functionality in android. I've tested a few multi-tasking apps but have found none so far that actually include this feature and it seems like it ought to be possible.

I'm not sure if this is possible, as it goes against the activity lifecycle on android.
For "background activities" try implementing a service

That's disappointing, but thanks for your reply.

Just scroll down to where it says "Service".
Hope it helps!

Yeah, I came across those sites when I googled before, but I can't quite understand how to do that as I am not a programmer. It doesn't sound like a very hard task. I mean, it would be just modifying the Manifest.xml inside the .apk, right? My goal is to keep a replacement launcher, contact app, dialer and messages app running all the time.

Hello guys, you can use app settings, the xposed module to keep certain apps from closing. I don't have it installed right now but the option is something like "resident" as far as I remember.

The one feature iOS has that I wish Android had..

Is the ability to manage app-specific privacy permissions--you can turn off an app's ability to query your location. I hate seeing the GPS reticle kick on when I open Facebook, but I don't have any choice but to agree to the permissions when I download the app. I know pdroid works, but this shoud be OS-level.

you could disable location settings in all the apps you dont want to have location used in? unless im misunderstanding you?
i do taht with all my apps including facebook.
the only time my GPS is turned on is for when i use navigation.

Unless I've fundamentally missed some aspect of Android, if you grant an app permission to use your location when you install it, there is no way subsequently to prevent it from using your location without turning off location access entirely. iOS allows you to install an app that wants to use your location, but then deny it access.

it mightve read that way, but i wasnt being condescending or anything. I hope you didnt take it that way!
was just saying, i dont have GPS turn on for any app that I use except for navigation. I turn it off in settings and in the apps when requested or when i see it in settings.
does it still track in that case? I never see the icon.

I'd doesn't matter what you have installed on android or iOS. Your location is always being tracked by WiFi or you data coverage. Unless you have your phone in airplane mode or turned off you will never have true privacy.

pdroid is not just an app. it has to be integrated into the actual framework of the os. therefore I don't understand how it didn't fulfill your request.

What he is saying is the he should not have to root and install a custom ROM with pdroid to be able to do this. His point was that it should be built in to STOCK android.

ah I see. that case is unlikely then. Google is pretty much king at mining data for advertising profit and I don't think they would do anything to restrict that unless forced by law.
also, unless you have a nexus phone, every " stock" android is actually already a custom Rom created by the phone manufacturer. some manufacturers make it harder to install privacy protection measures than others. that's unfortunately one of the downsides of open source.

Miui let's you handle each app independently... there is also a mod to I stall the LBE guard instead of supersu on any ROM and you can monitor each app independently. Search for the MIUI superuser app

[APP][4.3 & 4.4 KitKat] App Ops eXtended

App Ops eXtended is a launcher for the 4.3 AND 4.4 App Ops activity, as well as an installer for a more advanced version of App Ops with added features:
- search for apps
- filter out disabled apps
- sorting alphabetically
- batch grant/revoke OPs (permissions)
- ability to automatically deny permissions chosen by you on new app installs
- optional persistent notification to show revoked permissions for the current foreground app
App Ops X is a recompiled version of Android 4.3's App Ops which we've made available to Kit Kat now too.
We're going to improve on it and add new features, so please, if there's anything you'd like to see just let us know! Also if you have any problems with it, please send us a description along with your ROM. Thanks!

Can you add the option to take away ability from apps to connect to the internet, or to write to the USB storage, or to read the phone status and identity? That's what I would call extended app ops

Don't these apps work by listing ALL the permissions that an individual app can access ? So if it can't access the internet or GPS or or or it won't give the option to denied ?

App Ops lists some, not all permissions. Look at chrome, it doesn't say that it has any network permissions, neither write storage, but if you look at them in Settings->apps you can see it does.

Gotcha I never really looked at apps like chrome , I really only use it for games and shady apps downloaded from the internet . I agree finding a way to show all permissions would be great

Many thanks!! I was waiting for kit Kat version.

Yep, working on the INTERNET permission right now. App Ops eXtended uses the same AppOpsManager as the native app, which doesn't support it, so it's a bit more work, but we're getting there!

Looks nice !
If I may, once App Ops X is installed, the button still says Install App Ops X Maybe you could change it to "Launch App Ops X"

That's done, along with a few other features:
- notification that shows revoked permissions to the current foreground app
- batch grant/revoke a permission to all apps that requested it at once
- rules - automatically disallow permissions of your choosing to newly installed apps (like READ CONTACTS)

Don't see wake lock option in X version
First thanks for make this great app available on Kitkat platform.
I'm not sure if the following bug might be related to my phone only:
When trying the Native AppOps, all works fine and I see the "wake lock" option.
However when I try the AppOps X, I'm unable to see the option for "wake lock". I had granted superuser access to the app and phone is rooted. I'm on Kitkat (Build from CM 11). Phone is a Samsung S2 I9100.
If nobody is having this issue, then I would guess it's something with my OS or phone.

This is cool! Can you also present the apps sorted by name ? The standard app ops show the apps in random order, so it's hard to find a specific app you are looking for, if it falls under a section with a lot of apps.

They are actually sorted so that the app which most recently used that OP is shown first. We'll try to add a sort option by the next version too though!

In App Ops X on the upper right side there's a "settings" button, and there on the unlocked version the first option is for turning off the notification. If you haven't unlocked (purchased) though and you see notifications from App Ops X then that's a bug which we'll try to fix ASAP.

There isn't any way through the AppOpsManager as of yet. Even so, the device ID now isn't as unique as it used to be, since it's software generated as opposed to hardware. I'm still looking into it to confirm that it's so, but the most of the internet tells that it is.

[GUIDE] Using Apps Ops (or Privacy Guard) 4 blocking wakelocks & saving battery

Before I begin note for:
Everyone:
I am making this thread as much as noob friendly. So if anyone doesn't understand any term or anything please let me know through posting here or PM me.
Moderators:
This is my first guide. I tried to follow all the rules if my thread is breaking any rules please let me know so I can make appropriate changes.
If the thread is in wrong section please move it.
This guide is only for:
- Android 4.3 and above which has app ops (privacy guard)
App Ops (or privacy guard) can be used for:
- denying specific permission to a certain app
-checking which apps are kepping your phone awake and which apps are the one using resources like location, personal stuff, etc ( only if your app ops or privacy guard has " advance" option. watch video to know what it is.)
- preventing app from causing wakelock
-overall it can be sort of used like wakelock blocker, battery saver app ( because of its feature to block wakelock) and noob friendly way of determining apps that causes wakelocks.

PPT on Using App Ops( privacy guard) to its full potential (includes saving battery)
(Best viewed on laptops, computer or mobile devices with bigger screen)
I was a little late (actually lot late) to use app ops
It was recently that I started using app ops (now mostly know as privacy guard)
Not only can it be used for privacy purposes but it can also be used as battery saving app or wakelock blocker.
Different Roms have a little different app ops( privacy guard) some provides user advance options some don’t. Some even has little extra option and sort of interactive mode like xprivacy. (like temasek’s ROM which I use)
I am made this video with temasek’s ROM which is my favorite ROM.

I faced same problem once. Don't remember now when and why as ut was long time back. I think it might have something to do with your ROM. If you are using xposed framework try using "app ops" module. I will try to recreate this error when i flash different ROM (Which is at least once a week) if i am able to replicate this error i will let you know why and what caused it.
I flashed one ROM over another after wiping just cache, dalvik and system which lead to same error message except it was when i tried to access "developer option"
So did you change your ROM recently without full wipe or procedure as mentioned in your ROM's thread?

If you are using xposed. Try "app ops" module . uf there is app ops hidden on your device it will unhide it. But from some stock ROMs it has been completely removed. And in some custom ROMs developers might have limited its use(functionality).
Try asking in the thread of ROM that you are currently on. You will known for sure from there where the app ops is on your ROM.

you can give this app a try.
found one article here some text from that is below:
Users of Galaxy S4 Google Play edition handsets have started receiving Android 4.2.2 over-the-air update notifications just a day after the same update was rolled out to Play editions of LG G Pad 8.3 and HTC One.
Android 4.4.2 not only brings in new features and bug fixes, but also removes App Ops from the OS which Google claims was mistakenly tagged along with the Android 4.3 update. The Apps Ops allowed users to control how much access can third party apps have on their personal data.
the app for which i have given you the link installs some customized version of app ops. not sure whether it will work on your phone or not.

Can someone confirm for me what some of the permissions are actually for?
Wi-Fi change
Data change
Bluetooth change
Also, if I allow an app 'Wake up', but not 'Keep awake' - could the app keep waking the phone in an attempt to gain the wakelock which it is being denied?
'Keep awake' only applies if the screen is off, correct?
If I deny 'Keep awake' then an app won't close down while I'm using it, but it could be put into hibernation (don't know the correct term) by Android while it's in the middle of a background task? Like a radio app could just close, or a browser which is downloading something could just terminate the download before it's completed?

wake up means : if device is in standby mode then that app can wake up your phone from sleep. like Facebook app when you recieve some notification it wakes up your phone to show notification.
keep awake means: while your phone is in use. if you are using some app and it is performing some operation and your phone screen times out and display switched off. after a while your phone will go in deep sleep. this permission will prevent it from going in deep sleep mode and keep phone awake. for example if you are downloading something via some download manager. and you have denied that download manager "keep awake" permission. so after you screen times out and there is no other app or process that is keeping your phone awake. this download manager will not be able to keep your phone awake. so download will stop .
so you need to use these permissions carefully. make sure you don't deny some app permission which is essential for its normal function.
you can deny Facebook both these wakelocks if you don't care about getting facebook notification all the time
Wifi Change and Data change is normally shown in apps that uses data. and also have options like sync or download only on wifi or only on mobile data. it is essential for that app to determine the change. so that it can act according to its settings.
For Bluetooth change you need to tell me for which app you are talking about? maybe some automatic profiles app like llama, tasker, etc they need this permission as there are profiles or conditions like switch on Bluetooth when in this area or if connected to this Bluetooth device do this
few people denied "settings" wake up and keep awake permission and they screwed up their phone. they had to reflash the entire ROM . they reported no touch, device not waking up from deep sleep. etc.
so just be extra careful when you are experimenting with system apps.

I liked the idea about the app so I'm very excited to get it to work

Doesn't it say "ALL APPS" anywhere? Quite strange...
What Android version are you using?
Can you send me a log excerpt (
Code:
adb logcat
) or even traces of the running stacks?
What happens when you wait 2 minutes?

The app should run in the background and automaticly freeze pre-selected apps just like Greenify does, overwise it's not much useful to me.

Been using this app for a week and like it alot. Especially as it seems to be one of the few open source options.
Only thing I miss in this is the ability to freeze system processes or the bloatware apps coming with the phone. Many of them are possible to freeze manually, but unfortunately they dont show up in SuperFreezZ.
Then there is the problem with restarting apps. As dimqua mentioned there is a need for autofreeze.

Good point, I will add it when I implement settings: https://gitlab.com/SuperFreezZ/SuperFreezZ/issues/8
And see https://gitlab.com/SuperFreezZ/SuperFreezZ/issues/15.

Hello,
I am really interested in switching from Greenify to SuperFreezZ, but am not entirely clear as to what the differences between the 2 apps are (if any).
What difference is there between freezing an app and hibernating it (which is what Greenify does, right?)? Why would it be a problem to unfreeze an app once it has been frozen, and does this process differ from what Greenify does with apps that have been hibernated?

There is no difference between freezing and hibernating.
And neither SF (SuperFreezZ) nor Greenify have anything to do with unfreezing/de-hibernating, the Android system does this from itself when you start a frozen/hibernated app. It is a problem because you will have to wait some more seconds until the app is loaded and the process also consumes some energy. And it does not differ from using Greenify at all, except for the fact that the developer of Greenify doesn't warn you.
So - actually you will see what the main differences between Greenify and SF are when using them. There are almost no "hidden" differences.

Only thing I miss in this is the ability to freeze system processes or the bloatware apps coming with the phone. Many of them are possible to freeze manually, but unfortunately they dont show up in SuperFreezZ.
Then there is the problem with restarting apps. As dimqua mentioned there is a need for autofreeze.

The app should run in the background and automaticly freeze pre-selected apps just like Greenify does, overwise it's not much useful to me.

I implemented both of these features, you will have to look for them in the settings though. This is because they are rather for advanced users (that is, those who have a look at the settings).

I can now receive monetary donations: https://liberapay.com/Hocuri/! If you like the app, please consider donating something.

Please, add a root option to hibernate apps without accessibility service.

Can you explain if it is useful on android pie or just redondant?

Have you seen Drowser https://f-droid.org/de/packages/com.jarsilio.android.drowser/? It is also FOSS.

It depends. SF can completely prevent apps from running in the background.
Newer Android versions (like, Pie) let the apps run in the background fewer and fewer when they are not used, to save battery. SF can make SURE that apps do not run in the background at all. From https://gitlab.com/SuperFreezZ/SuperFreezZ:
Get back control over what runs on your phone (this did not change)
Enhance battery life and reduce mobile data usage by freezing rarely used apps (hint: the system will also let them run in the background only a little, even without SF).
Especially useful while you are on a tour, where you need only some apps but a long battery life
If you want to be really sure, you will have to test whether using SF saves battery yourself on your particular phone with your kind of using it.
Update: Apart, apps cannot use the camera or get your current location or use the device sensors while they are frozen.
Update 2: Also see https://www.xda-developers.com/superfreezz-freeze-background-apps/

Don't you intend to add this function?

It depends. It seems not to make sense to just duplicate this functionality on the first sight, but: Is there any reason why you would prefer SF over Drowser?

First of all, thank you for this cool foss greenify alternative.
I don't think you should worry much about copying that since "am force-stop" is first result when searching "kill android app command" and the accessability thing seems like a more complicated hacky workarround. Having this as an option for rooted devices would be helpful, especially for killing apps while locking the screen as I could not get that feature to work reliably so Im left with freeze shortcut. I like this freezZer more because I find default delayed freezing the most convenient way to save some wattbytes having way more installed apps than I'd like to admit. (Seriously, why would someone need to have an app that calculates dew point? No idea but it prooved itself that one time and it's only 127kB!)
Intelligent feature could maybe be improved by logging usage and delaying freezZing more (in defined bounds) the more frequently given app is used, but this may be a hustle to implement.
