If i understand Android correctly, it sends applications into a "background" mode when switching tasks? I would like to prevent that. There are some apps (like games or browser) that need quit a bit of time restoring the last state so this would be usefull for some tasks.
Is this possible ?

Well, switching to background mode just marks the application as not displaying anything. The way memory management on Android works, if foreground apps (i.e. apps that are actively displaying on the screen) need memory and there's none available, then background apps will be put into a stored state that frees up memory for the foreground apps. Coming back from that stored state is probably what you're noticing. Android also tries to keep a certain amount of unused memory around and will put background apps into stored state to achieve that. We do have pretty limited memory available on this device so some level of pausing is always going to happen. See also: http://andrs.w3pla.net/autokiller/details
You may be able to reduce how many background tasks are put into storage by tweaking the minfree parameters (using e.g. Autokiller Memory Optimizer from the market) to tell Android to aim for a smaller pool of free space.

Thanks, i'm will give it a try. Is it also possible to max out swap before sending apps to background? I think restoring the ram-state from sd would still be faster for several apps.
Edit: reading your post again, i'm not talking about a tasking switch delay, but apps that completly reload themselves when switching tasks (DolphinMini page load,DungeonHunter as examples). Just to prevent any confusion...

Oh... Sorry I misunderstood. I don't know anything relevant to that case.
I've spent a few hours trying to find how to make certain Droid apps maintain their foreground state when put in the background with no luck. Perhaps it just can't be done.
I'm thinking of the Cydia iPhone app called Backgrounder which lets you choose which apps maintain foreground state when put into the background.
This is necessary, for example, with a note application where you are switching between taking notes and looking up info. Every time you switch back to the note app, you need to go back into your note, put it in edit mode and navigate to the section of the note you were editing. If it were acting like a foreground app in the background, when switching back to it it would already have your note open and be in edit mode with the cursor where you left off.
K9 mail has a similar problem where if you have an email open, switch to another application, when you go back to K9 it takes you to your inbox again where you have to navigate to the email you had open before switching.
Is there a tool similar to Backgrounder for Android?
Thanks.

Looking for such tool too. Making app to stick with its foreground state even though it is actually in the background. (Make it appear in notification?)
ZDBox is a useful tool... you can download from market its free and the app has the abbility to:
★ Traffic counter: Monthly/daily mobile data usage overview, shows remaining data traffic, detailed data usage information for each app.
★ Do not disturb: Just set days and the time when you need your privacy and you won’t be disturbed by your phone. Set phone to silent, vibration or airplane mode.
★ App lock: Protect apps with a password or pattern, for exmaple your contacts, Facebook, Twitter, Whatsapp,Gmail and so on
★ Task killer: Kill all apps at once, define protected apps which won’t be killed, set auto kill when screen gets locked, mark single or multiple apps to kill
★ history eraser：clean your（Browser history,market search history,Google Map search history,Gmail search history,Clipboard）
★ Notification bar: One tap on the bar shows remaining battery time, running apps, how much data traffic is left and if app lock is active or not. A tap on these informations starts ZDbox.
★ Uninstaller: Shows used/available internal and SD card memory. Apps can be easily uninstalled. Single or multiple (batch) uninstall possible.
★ App to SD: Move apps to your SD card. Single or multiple (batch) move possible. Only for Android 2.2 and 2.3.
★Cache Cleaner:With Cache Cleaner you can clean your cache of phone.protect your secret without a trace.
I hope you can use for keep your running applications with that app...
sorry for my english...

This will not help since the task killer which kills the background apps in inside the android system not an external one.
We must find a way to control the internal one then...

Guys, I'm so much looking for a solution of this same thing. The closest I came to is Ram manager. Has a xda threat and can be found in the play store. But it also can't manage to lock an app and prevent its killing (although it helps a lot). I need my navigation always running and it is silently killed or stopped while I'm looking at my mail or have a phone call. This is ridiculous. Have you found a solution. Some way to protect an app from killing and lock it in the foreground. I mean how are they able to do it for the apps which are in the system tray!? Like antivirus apps and tons of other. I can't believe xda experts don't know how...
I would think that Antivirus apps run a service.
In Mioze's CM6 there are build prop edits that might work, but I never tried them.
Code:
# apps to be kept in memory (specified by process name)
# use with caution, RAM is limited!
sys.keep_app_1=
sys.keep_app_2=
I am not an expert and can't tell the difference between service and an app running. What you're saying makes sense, but I need clear instructions somewhere to make an app protected from killing. Thanks for helping.

I pretty much fixed android multitasking - even on ense 4.0 and 4.1
http://forum.xda-developers.com/showthread.php?t=1900626
Testers welcome.
And for locking an app in a foreground state, my SuperCharger can do that via BulletProof Apps menu.

I tested that and almost became an expert. I'm not so sure if it is completely solved, although I have to admit that you have done a great and recognized job.
Just tell me can the script for bulletproof apps work alone, without the supercharger script. Many ROMs have their own memory settings and one is afraid to cover them with supercharger script settings.
But if bulletproof script can run and do the job on itsown then the problem is really fixed.
Yeah its separate.
Alot of devs say dont supercharge because they dont want to be showed up and scare their users lol
But hundreds of roms come supercharged anyway.

Thanks for answering!
So I'm going to try running only the bulletproof script without the supercharger script and set an app to be UNbillable.
Should I set it to run on startup!? I'm using custom ROM. The last revolution HD.
The init.d script would run automatically.
So you dont need to configure anything.
Whatever app is in the hitlist will get bulletptoofed soon after running the app.

I am trying to get this configured. But I only want to run the bulletproof script, not the 99SuperCharger script. I just want to keep my rom's memory settings, cause I am OK with them.
But both of the scripts (99SuperCharger and bulletproof) are going to reside in the init.d folder of my custom rom. So they will both be started, aren't they?
How can I make only bulletproof script run at boot. Should I just delete 99SuperCharger from init.d?
Hi
I want to change an application to system application. Is there any application which can do this?
Sent from my MB525 using XDA App
it's really easy to do in a terminal, or through adb
find the app like this:
Code:
su
cd /data/app
ls
then find the file name of the app you want to move, and:
Code:
mv /data/app/<name_of_app>.apk /system/app/
You could probably use any of the root file explorers on the market to do this too - just find the file in /data/app and move it (or cut and paste it) to /system/app
You need to restart after this, because the apps in system only change on startup
What do you mean exactly?
Want to grant the access to ALL the system's resources?
Or do you just want to move an application to the system/app folder?
First case, you can't. Your application would need a platform key.
Second case, just root your phone and use a file explorer with root functions. By the way, this won't give to the application any special power...
Would this keep an application from being killed in the background if it is moved to /system? For example, on a MIUI rom, using 'alternate drawer' it will close after X amount of time and then reload when you open it, which defeats the purpose of having a quick loading app drawer. If I move it to /system would it prevent this?

I don't think so.
Any process which does not belong to the Android core can be killed when the OS claims memory.
Moving an app to /system/app does not turn that app into a piece of the OS nor turn its process into a critical process that must be preserved.
I've never tried a MIUI rom, so i don't know much about it..

Ah I see..Thanks for the info. I wasn't sure what the criteria was for Android to kill a background app and really have only experienced this issue/question with MIUI and the alt drawer app.
Oh, even I am facing this problem. After some amount offers time the applications gettingkilled somehow, in my barebones rom with cm7., so making it system won't help it.

@obscurant1st, @civicvx94
Rather than the android internal task killer it could be the problem is related to the rom you use.
You are on GB, if i am not wrong both, CM7 and MIUI, undervolt the cpu. Try to increase those values, give a little bit more volts and see what happens.
If the problem persists, look for the internal task killer settings in the scripts loaded at startup (look for info at the rom's page) and try to adjust them.

I use Barebones rom with CM7 - Can you provide a little more info?
There is an option to do it in titanium backup, not sire of it's effectiveness though.

This is taken from Barebones page:
Code:
Reduced vsel:
- 300mhz-30 > 20
- 600mhz-46 > 38
- 1000mhz-58 > 50
Check for SetVSel app, if you can't find it in your rom download it from market.
Adjust the voltage using that app, it's quite easy.
Also, once rebooted, open SetVSel again and check your settings in order to see if they're still effective.
I'm no pro, so forgive anything stupid I may say in advance. I recently learned that any android application has permission to see any application installed on your device. I'm a bit of a privacy nut, and I have concerns with this for a plethora of reasons. I was hoping to learn of a method that would allow me to somehow prevent apps from being able to see what's installed, or at minimum, mask the actual application names so the data an app gets is useless for any purposes they may have for it.
Is there any way to achieve such a thing?
I'm no pro either, but what I do is I use two apps to accomplish this. The first is MyAppSharer (no root required). The second is Advanced Permission Manager (again, no root required). Both can be found on the play store.
First I use MyAppSharer to create an .apk of the app I want to isolate. Place it In the download folder (or any folder of your choosing). Next I install the .apk with Advanced Permission Manager. While installing simply uncheck the 'view other apps permission' or whatever it's called and that might work.
The only concern I have is that apps usually check to see if they have access to all their permissions before startup, and if one is missing it might either not allow you to launch the app or or will crash. Or it'll work perfectly fine and all's well
Good luck
I think you need to hide apps and permission manager. For me, I used to use Greenify, the ForceStop as permission manager, which are available on xposed module repository, but they both require root.
For hiding apps, maybe the "PrivateMe" can help you, it also can hide photos, install apps in hidden mode.

The sudo hide xposed module is exactly what you want to figure out
You will get first list of apps where you have to select ''which app to hide"
Then you will get second list of apps where you can select "from which apps to hide that app"
If you want any help regarding xposed,reply me back
