Okay, digging deep into Android's source.... not for the feint of heart, and not for those whose coding skills are somewhere just above, "Hello, world!" (Me)
Here's the deal. We all know, with Froyo, Google disabled task killers. No app can kill another app. I for one am happy, because killing all apps when your screen goes off is stupid, pointless, and all kinds of harmful. Well, happy but for one little thing....
Killing other apps still does have a purpose! Specifically, in my case, I want to replace my long-press home option with a cool app switcher that also gives me the ability to kill a running app if I know I am done with it for the day and it refuses to die naturally. I'm sure there are other legitimate uses for it, such as killing everything before a benchmark. Sure, these are very specific, uncommon uses, but a thousand apps on the Market exist for specific, uncommon uses, and I think that most hackers/modders with su here would know better than to let a task killer run rampant. Anyone wanna discuss re-enabling this on 2.2?
Edit: I should correct myself. I keep saying "app," what I mean is "service." I know you can still stop (most) apps, but not services. Which keeps a lot of apps running, despite your best efforts. Forgive me for misusing the words
wait task managers dont actually kill in 2.2? This is news to me, as one I have downloaded seems to work fine..

Taskiller will show the app was killed. I'm sure many others will too. But kill an app, then go to Settings>Applications>Manage Applications>Running, and you'll see that it's still running.

Forgive the obvious question but can't the services just be killed by a root request/process? If so, creating an interface for this should be easy as pants.
Of course, root is required but that shouldn't be a constraint.

True. But wouldn't it make more sense to allow the dozens of non-root apps that already exist to do this, rather than have to re-write an app that does the exact same thing, but has to use su? It would be safer, too. Running everything as root all the time runs contrary to the whole idea of Linux. It's better to give apps the permissions they need, rather than give everything unlimited power.

Oh, I see. It might be useful but that's the essence of the Froyo changes... it can't be done now without root. You've have to compromise the security model... probably not a feasible route...
I think you are mistaken, maybe in Manage Applications it still shows it as "stoppable", however... I just did a test.
1. Opened DDMS on my PC.
2. Took note of an app to test with (speedtest) that was currently running.
3. Opened Advanced Task Manager.
4. Killed speedtest with task manager and watched it disappear from the running process list in DDMS.
Obviously ATM was able to kill the task. And, just so you know, it did not start running again. Also, it was removed from the "Running" tab in Manage Applications, so you are double wrong.
And, in case you were going to further the argument that you meant to say "Services", I just killed the PhoneFusion VM service with ATM, and it was removed from the running process list in DDMS.

Or create something that uses su to kill these processes for third-party apps, without the need for them to have su. Similar to superuser apk, but on a more specific level. Or, we could make it even better, and have superuser hand out specific, user-approved permissions, rather than permit root access as a whole to any app.
Apparently there's not a lot of interest in this, but I thought it would make an interesting discussion.
Hi! I would like to know app (free if is possible) to get my phone back if I loss it or if my phone is stolen. I have heard about Cerberus that is a very good application, but I would like some opinions about it.
Thanks in advance!
If it work's in your country Samsung Dive. Free and available out of the box.
I personally use PhoneLocatorPro, very much like Dive but this can take pics on attempted failed login when you have pin/pattern etc activated.
Also like the fact as like Dive you can place it into system/app so you can turn GPS off but when tracking on website it activates GPS.
There are free alternatives, search the market and read user reviews.
You can find a roundup of many apps here: http://www.androidpolice.com/topics/features-2/mobile-security-app-shootout/
Avast mobile for android all free with remote wipe etc etc
Works for most.
One great feature of Samsung Dive is that it is not controlled by SMS, I say this because those can be blocked with the wrong settings. Here is a real life example that happened to me personally.
1: I installed Avast on my sisters Android phone (not Samsung so no Dive)
2: I tested the locate feature and it worked
3: A couple months go by and some app updates occured. Specifically Go SMS which suddenly turned on the feature to stop multiple notifications by blocking other SMS apps (I have been confused by this before on other phones until I figured it out)
4: Suddenly I went to use the locate feature and it never worked because Go was blocking it.
Luckily I wasn't trying to find a lost phone but just cheaping out on asking for directions to a birthday party.
I may suggest using two, Dive and another. For features from both.

Here's the best advice: Take a note of your IMEI number, as if and when you lose or have your phone stolen, the first thing to go is your SIM. Phone your network provider, and ask them to block the phone completely by giving them the IMEI number and your mobile number.
They will do this for you, as I have done this before. This will render the phone completely useless to the thief. You can then have your same phone number ported back on to another new sim if you want with the balance added.
Also its handy for the police report/Insurance claim etc.
And a few day's later I got a call from the police that the phone was in a local phone shop! The Idiot took it there to try and get it sorted, but the guy new the IMEI was locked/Barred and inquired about it, and contacted the police.
So happy day's
PS I got a new one fron the insurance anyway so beware, they can flash your firmware and get rid of all your fancy anti thief, but cannot change your IMEI
FPMen
You should try Avast, it is a very good app, I use it too, but you should take care of your beloved phone!
Thanks for your answer! I will try some free app and I will copy my IMEI too... every thing that I could do to protect my phone... I will do it!
im using netqin security..
My favourites are seekdroid, androidlost, lookout and avast. I use them all.

+1 for Avast. They bought the really nice app Theft Aware, and they improved and integrated their features into Avast. It's especially useful with rooted phones (offers more security), but works with non-rooted devices also. The best thing about it is that you don't require a network connection for it to work (like Samsung Dive does); and it can force data connection on, so you can connect with Dive . You can control the app via SMS. And it's also free on the market.

+1. Been playing with it since last night, it really is excellent.
You can get rid of the virus scanner/firewall bloatware easily too.
+1 for avast, really nice app
avast is good because it needs no internet connection to work. Most anti-theft apps only work when connected to the internet...
i first installed avast, then installed the anti-theft and gave it a nicen ame
then i unstalled the anti-virus because i dont need it and it uses to much battery.
I would really recommend hxxp://phonelocatorpro.com/ only cost about $4.

Hi.
My girlfriend has a Samsung Galaxy S II that has been acting a bit weird recently. Battery life has become extremely short, and she discovered hundreds of files all with names beginning with "tracker-c6446d57267343". Most mysterious of all is that something is somehow using the GPS even though it has been deactivated in the settings.
I'm suspecting her phone is infected with malware, and I'm planning to do a full wipe next time we meet. She's downloading AVG from Google Play right now to run a scan, but I'm going to do a full wipe anyway just to be sure and because she wants to have a clean start anyway.
I'm mostly curious if anyone has encountered this before. Is it malware? If so, how harmful is it? Keylogger, possibly?
Thanks.

Exactly. It is. Odds are someone installed an app on yer girlfriends phone to be able to track her, tape pictures with the camera remotely, steal her credit card info, use the mic to record what's going on , etc. All of this can be achieved with ONE app and allows the person who installed it to remotely access the device. Also the app hides itself from detection in the app drawer and in the app manager . The legal reasons to install it are for if u lose your phone. But if someone got a hold of her phone they could easily have put this on and set it up within minutes. In other words. Someone can hear and see everything she's been doing.

I'm finding it highly unlikely that any of her friends would do something like that, not to mention that none of them have the technical know-how (yes, I know it's not hard, but none of her friends are even technologically adept to pull something like this off) to do it. If such malware has been installed on her phone, it most likely came bundled with some app she downloaded. She doesn't get all her app downloads from Google Play.

There is no such thing as malware on android. everything you install tells you what it has access to.
The only thing like malware, would be an application that records stuff and sends it out, which would be listed when she installed the app, Tho im sure most rarely pay attention to that screen other than hitting install.
There are no viruses, no malware, or anything "hidden" that can attack stuff without your permission.
Wipe the phone. Dont install pirated apps or stupid pointless apps.

Malware can definitely affect android. Sure there are safeguards built in to reduce the chances of it happening, but they rely on the user to enforce them. I can almost guarantee that a majority of android users don't look at what permissions an app is asking for prior to installation. I know for a fact that out of the 5 android users in my house I am the only one that checks permissions before I install anything. In addition, even if one is checking the permissions, a malicious app can easily disguise itself as an everyday app that requires the permissions the Malware needs but would be overlooked because the host app has a valid reason for needing those permissions.
A dialer, email, sms, social networking app will all ask for access to your contacts. And it's necessary for that app to do its job. Well if that same app has unlimited access to your network then it can now take your contacts and upload them.
Now a virus is another thing all together. While it's possible on a rooted phone with rw permissions in the system directory, it's unlikely since most apps exist in a "sandbox" so to speak. It wouldn't be that difficult for a root explorer app to gain access to your /system directory and wreak havoc and then target your sdcard and wipe out your data. But not before uploading whatever it wants (a lot of explorers require network permissions for cloud service, etc). But then I guess that would be classified as malware and not a virus
And lets not leave out all the apps that use social networks to login..
But the last two Lines of your post say it all. Stay away from pirated apps and watch what 3rd party apps you're trusting these permissions with.
hey i have a rooted i9305t running custom rom liquidsmooth 2.5

That's quite an interesting request, I don't know of any bullet-proof solutions but turning account sync off and using a task manager to kill all non-essential running apps should mean that no apps attempt to use mobile data.
I've not used one but I'd imagine there are application level firewalls available for rooted phones, maybe someone else has experience with one?
Would be interesting to know which apps you want blocked?

thanks for the reply.
in perspective ive gone from a LG p500 to a i9305t haha huge jump for me.
ive only just rooted it and installed a custom rom so now i dont have no samsung bloatware running or any other non useful things running cause they didnt come with my rom . yeah i dont ever auto sync and since ive asked this i tick restrict background data while on wifi so pretty much alll my apps arent using BG data. now the only problem with a heavy task killer is it will kill my alarm all the time welln it used to on the p500. so i would have to install unistall everytime or freeze it i have rom manager pro i like the task manager in there. ill get on my phone and screenshot you whats in there after this maybe you could tell me whats actually running and whats not would be great.but from the looks of it barely anything i usually only play f1 2012 and ops 2 online so i want as much as possible incase lol. since the new rom its changed dramatically in my task manager.
application level firewall. what would that do mate?OH and also. i have TWO cpu/battery profiles in rom manager. one set for SCREEN OFF wihich i have it use 700mhz max 200 min and SCREEN ON max all the way. would that effect my active hotspot in anyway?like is being restricted by having that profile set?WAIT its always on charge while wifi is on. so if i make a new profile for when the charger is plugged in it shuold be set to full. but the screen would be off? so would those profiles clash in some way?thats why i only set 2 didnt wanna make it mess with the cpu all the time. sorry lol any help with anything is GREATLY appreaciated. im only registered on here so ill always be here now.

I have a good friend who believes her husband, they are separated and divorcing, has some kind of spyware on her phone. A lot of her claims as far as strange things happening with her phone, seem kind of impossible but her ex was involved in some high level activities in the Military. For one, she says she can factory reset her phone and all the strange things pop back on her phone. The first thing I looked at was what apps on her android were using the most data. I will include a picture of it but I personally have never seen anything like it. Many of the apps that are shown are "restricted".
Now, the app store for example. She claims she never installs new apps or really even looks around on the app store however the data use on it is insane. She also has NO work stuff on here and has no idea what osulogin is. Does anyone have a clue??
osu login is a preinstalled system app.

Thank you for letting me know that. Did you notice or see anything strange on there? Like why is the appstore data so high and all the app restricted? She said he ex was like scary good on cell phones.

Have the phone reflashed to its original stock rom. Change Google account password.
Turn off wifi. Get off social media. Never leave anyone use your phone out of your sight... if at all.
I doubt the ex would risk his security clearance and job like this. The DOD has a vast array of spyware tools... I've seen some in use.
You upload and scan any app you want to with online Virustotal.
