An extension of the build.prop tricks - Android Q&A, Help & Troubleshooting

Hi folks,I hope I'm in the right forum for this (otherwise could a moderator move this topic ? thanks).
I was thinking of the well-known build.prop trick to force the home launcher into RAM :
ro.HOME_APP_ADJ=1
I was wondering if the same trick could be used to force other apps into RAM. I'm no expert, but assuming the command is ro.[NAMEOFTHEAPP_APP]_ADJ=1 , we could have for example :
# Messages app :
ro.CONVERSATIONS_APP_ADJ=1
# Phonebook app :
ro.PHONEBOOK_APP_ADJ=1
# Telephone app :
???
I have been told this trick wouldn't be necessary because these 3 apps are auto-reloaded into RAM. Well, all I know is that within my GB Arc S, these 3 apps are fast after a reboot, and become very sluggish some time after. I guess they wouldn't if they were really forced to remain into RAM !
Sure, in case of a lack of RAM, other apps would become slow. But I'd still prefer if the three apps that I use most were fast and the other ones were slow, than the other way around.
Could you please help me with these commands ? Thank you.

no possible in any way... + that "hack" is old and does not work anymore (ICS+)

That "hack" works under GB, which is great since I'm running GB right now and I don't intend to go ICS or JB for the moment. :angel:
This being said, I'd appreciate if you'd explain why under GB it isn't "possible in any way" for the above-mentioned apps, while it's possible for the Home launcher. Just trying to learn something here. Thanks.

(thanks to Sgt. Slaughter for moving the topic to the right section)
Hey folks, would it be possible to get a decent answer ? I think my above question is clear enough and deserves it for those like me who run GB...
Thanks again !

[Q] Noob questions..

Hi iam new to all this, and i try to read so mmany things that i can, but not all is easy to find.
1: When you port a rom from 1 phone 2 another, how do they do it, why is there so many problems with diff aps? If i see CM they seem to get things to work on diff models at the same time, why is that?
2: What does 9 png mean i know that png is a picture extension.
3: Why is it from what i read a pain in the *** to remake aps to another phone
4: I use the new rom with sence 2.1, i really love it, but i would like to remove the names on my aps/shortcuts (forgot the real word for it) like you can in adw launcher, is this possible and how.
Thx in advance, for this site and hopefully answers

As far as I know the hardest thing to do in order to make a custom ROM work is to make all the drivers working. They are usually developed by the hardware manufacturer and are available only as binaries so it is not so simple to make all the system work perfectly.
I know this explanation may not be complete, but I hope I have clarified the basis at least.
Thx, it was what i fugured, so thx for answer
The problems with remaking apps is they are usually for a phone with a higher resolution,so things dont fit properly
Ha ha... you can go read what ogo2 have been doing with the salsa rom on dev side to see what happening. I've been following that thread for quite some time.
Give his rom a test drive. Best way to know this issue is to experience it.
About rename or no name on app, I think it's a launchers function. I just learn that you can rename or leave the short cut blank in "go launcher ex"

[MODS] Multi Core Governor's/Frequencies (QCBeta1) + V6 Supercharger (U9RC11T4)

ALL ROMS AND DEVICES SUPPORTED​for both of these mods listed below
single / dual and quad core
V6 super Charger in post 2​
MULTI-SINGLE-ALL-CORE GOVERNORS AND FREQUENCIES​
this is a patch which allows you to edit the governor of each core independently, as well as setting each its own min / max frequencies, IT'S NOT MY WORK AND ALL THANKS GOES TO Smokin1337
Firstly dl the zip, then flash via your chosen recovery, I flashed on fresh installs so I recommend you wipe your cache/dalvik cache to be on the safe-r side of life , if flashing over a *settled* rom
You will then need to run the command "su" in terminal emulator , followed by "cpu"
Then all settings are self explanatory inside the terminal emulator,
Here's the op
http://forum.xda-developers.com/showthread.php?t=1584508
Here's the link to terminal emulator in the play store https://play.google.com/store/apps/details?id=jackpal.androidterm&hl=enO
This mod , may be cancelled out by other mods and/or settings saved from them, I would recommend clearing data from system tuner, set CPU, CPU tuner etc, and reinstalling them without making changes to CPU , also disable forced dual core if you have a 3rd party app enabling it. Er........ I think that's it
.....nope, if you restore from apps such as titanium back up, any data containing CPU configs you restored may need to be removed too, if you want to make sure you are getting the settings set in terminal emulator and not those launched via init.d or on boot completion
Enjoy​
V6 SUPER CHARGER SCRIPT ​
LIKE A BAT OUT OF HELL............. ReDraws n' Lag Will Be Gone!​
its like having a turbo on your device, lots of work has been put into this dont forget to go thank Zeppelinrox on The OP below
it has worked for me on his previous releases and accross many roms,
you may need a busybox update, to prevent a possible cause of a boot loop, but it does auto detect version,
and it is easy enough to upgrade busybox version,
with this app https://play.google.com/store/apps/details?id=com.jrummy.busybox.installer&hl=en free from the market/play store,
you will also need an app like script manager https://play.google.com/store/apps/details?id=os.tools.scriptmanager&feature=search_result free from the market, and dont forget to turn the little su android button green to run as root when running the script
heres the OP, http://forum.xda-developers.com/showthread.php?t=991276 ,
thanks to Zeppelinrox
heres the latest version

Ok...
Tell me if I misunderstood, but what I see is basically a clever mod that sets different settings for multi core CPUs and also the Supercharger script by zeppelinrox.
Now, how are these relevant to X8? It has only a single core CPU, so the mod is kinda pointless for the X8 since an app such as SetCPU can handle this function. Also, the Supercharger script is not new or unknown to us X8 users, in fact I believe there are 3 threads on that topic.
So how is this Android Development? I don't see anything here being developed by the OP. I only see the publicising of some nice tweaks, one of which is useless to the X8 and the other is already quite well-known. This should belong in the General section, and even then it wouldn't serve much purpose. Though I understand the sharing of certain useful mods here, I don't see its relevance.

Ok. The multi governor mod is, afaik, only useful for phones with multiple cores as then it can be used to change how each core operates, potentially increasing performance and maybe reducing battery life. A single core phone like the X8 won't benefit from it since it doesn't have multiple cores to change individually. You claiming that it works might be due to a placebo effect as it does nothing for an X8. Seriously, think logically on how a multicore-targeted individual core governor will help the X8. Not every tweak works for every phone and not every tweak is one that improves performance.
As for supercharger, I agree that it is effective. However, many X8 users already know about it hence publicising it again in a new thread is pointless. Though we appreciate that you want to share your findings with the community, this is not the right way or place to disseminate the information. Doing so in a related existing thread would be better and also since this thread contains no development, it should not be posted in the development section.
Ok everyone stop posting.Its upto mods to decide.
However,no matter how much you deny (like,this community is full of haters), SpyderX is right. This thread is just for increasing thanks meter or whatever.
One thing have to clearly understood : Dev section belongs to people who know about android.Its not for sharing stuff someone else creates. The Original Developer has done developing AND certainly its not you.Just saying all credits to him/her isnt enough. Its clear that OP doesnt know what he himself posted.He has little knowledge of scripts.
I dont want to get into verbal argument here.

Both these were developed from scratch, no not by me, I did state that, and yes, it is effective for single core devices, and yes i know system tuner, setcpu and CPU tuner etc, all do the same job, but, why waste app space, when a script can do the same job, but can be controlled via terminal emulator, if you don't like it, don't use it, wanna hate, fine,
My son owns an x8 not me I was keeping him pimped, and thought I was doing you guys a favour, .....oh well, back to the EVO 3d and s3 forums for me, see ya's
what is it for ?? I have tried to install it and then I wrote in terminal emulator,but there were many choices ...set governoor,set max cpu,set min cpu,disable/enable sticky mode ....what different is it with set cpu in setting>>perfomance ??

It simply allows full control / choice of governor, min and max frequency instantly, without the need of a reboot or init.d script, as for the supercharger script, its pretty self explanatory, it makes small system changes, manually giving you a choice of options , try it, you won't be dissapointed
I think all of moderator must give him a chance to share it,may be it is usefull mod for all of shakira users....may be in the other section too !
Ok here's the thing. Arjen (one of our Mods) has clearly stated in his sticky that Android Development section and Original Development section are for SONY ERICSSON XPERIA X8 SPECIFIC ANDROID DEVELOPMENT. Anything other than such should be in the General or Themes and Apps section. What SpyderX and a few others tried to do is advice you politely (take note that they didnt curse you or anything) and all you've done is remained hard hearted and ignored them. All i can say is im not like them.
1. Opening a thread about someone else's work is not X8 Android Development material, especially when it was developed in another phone's forum.
2. Making threads in another phone's forum just because a family member or friend has the said phone is, how do i put it...unwise. Especially when he/she doesn't bother to read our stickies or double check on existing MODS.
3. Saying "Fine, I'll just go back to my old forums where im appreciated" doesnt help your case. It just shows you weren't sincere by trying to help people with this MOD and that you're a thanks whore.
Im sorry its so long but I've had enough idiocy flooding our forums.
P.S. : I typed this whole thing via X8. Show some respect by quoting it if you have a good comeback.

[Q] How to keep/force app alive in background ?

Hello there !
As a first time user of Android coming from an iPhone 4 with iOS 5.x I was amazed by the SGS III that I own.
So far, so good.
However I have a huge issue that is really starting to get on my nerve : why the hell I cannot keep my apps running in the background ?
I had friends trying to convince me to go to android, saying how it's rocking, how it's multitasking is awesome ... WHAT MULTITASKING ?
Many of you may know, but iOS finally brought multitasking with iOS 4, something people said that was really lacking to iOS when Android had it for a long time - let me laugh.
Well, let's be honest. Yes there is some sort of multitasking thanks to services that are not killed by the system, but I do not use them, I only need them to perform to do wahtever they are supposed to do.
And also between your recently launched apps as long as you keep switching between them in a very short amount of time.
And that is all.
So iOS 4 brought multitasking on a phone with only 256Mb of RAM (iPhone 4) and with only that much, I managed to keep running three games : Lords & Knights MMO, Wolrd War and iMob. They are not 3D games so they do not use too much RAM as would do a 3D game such as NOVA. And, the cool stuff is that the multitasking on iOS keep the apps as long as there is free RAM (I even managed to go as down as 17Mb, and then the system killed some (not all !) of my apps !)
That was really nice. Before iOS 4, I had to relaunch them each time a notification brought me back to them (they are internet dependant games). And with iOS 4 and then 5 and today 6, I can enjoy switching between them without lag, without relaunching as long there is free RAM.
With android, I CANNOT DO SUCH ACTIONS. Even if ICS is nice, fast on the SGS III, when it comes to multitasking I feel like I have been brought back to iOS3 on my iPhone 3 and 3Gs (thank God, SGS III is fast enough to relaunch the apps in not time, but stil...)
As I said, I launch my game, go back to home screen, lock the phone, unlock it minutes after and the games are gone. ALL OF THEM.
Here is what I found out in order to solve this situation :
- based on the kernel version and model, android will keep killing apps that are not services after a few minutes in the background ;
- my games that I want to keep running do not offer the possibility to keep them alive in the background ;
- I tried many apps (ram manager pro, auto memory etc...) none of them helpt me although they did offer features that would be the answer I as been looking for.
- I heard scripts would solve this situation, but I dot not know any of them.
So what is next ?
It is simple : I would like to have an app, or a tweak or script or anything else, but easy to use, that will help me keeping some of my apps alive in the background.
Thanks to anyone who could help me out with this.
PS: I have an international SGS III wit CM 9 running on it.
CM Version is : 9-20120909-NIGHTLY-i9300
Kernel version is : 3.0.15-CM-g026d5ce [email protected] #1
Build version is : cm:i9300-userdebug 4.04 IMM76L eng. .20120909.083444 test-keys

If it is the rule, I will let go my thread further back in this forum in hope I will get an answer somehow to a matter that has been troubling me for months.
It can not be done as far as I know.
A few hacks/apps try to lower the oom value of apps, but it only last for a limited timeperiod.

Is this some sort of a joke ? Are you saying that even though I have plenty of free RAM I cannot use them to run apps in the background ?
This is ridiculous to say the least. Where is the multi-tasking ?
Anyway, thanks for replying.

With that attitude you won't get anywhere, you can't just come here, click your fingers, and people jump to your service.
For a start your initial post is virtually incomprehensible, so maybe start by trying to clarify what your problem is

maybe i m newbie here but when i see some1 i can help i help them first i did open in the wrong section people say nothin but go to help section and in here nothin usefull i m not angry couz i m not responded i m angry couz people make responses that doesnt help my problem is simple apps are restating after a while they are not crashing they just restarts and i m thinking its couz of ram-rom management.
the reason nexus 4 will have better multitasking will be because its vanilla so has no bloatware and also it has 2 gb of ram where sgs3 has 1. most roms have some sort of multitasking fix and scripts to help free ram if thats what your asking. for example on the rom i use i have 200mb free most of the time.

Looking for straightforward advice on how to make this phone good

Hi everyone!
So long story short I used to have an Xperia Neo, and a few months ago, ending up in the xda developement section here, I decided to try and unlock the boodloader, root it, and put Cyanogenmod 11 on it, after hours and hours of googling.
That phone is now almost destroyed (mechanically, because of myself) but I have another Xperia, this time a Neo V, which I'd like to "improve" in this way.
I am wondering, anybody has any advice on how to go about it?
This is what I'm looking for:
- Have at least some modern apps working (whatsapp, spotify, messenger?)
- Have the ability to put them on SD card and not internal memory
- No bugs on common stuff like telephone, SMS and browser
- No extra battery drain than what I already have
Any advice how to go about it? Should I go the CM13 way? CM11? Is there even one stable custom mod anywhere I can find without bugs? My CM11 was rather buggy and didn't support most apps (no facebook messenger, etc), and I couldn't put all of my programs on the SD but just part of them.
Any help would be appreciated. Just something like "oh this mod works well and the links are still alive, go here *link*".
Hope I'm in the right section.
Just to be clear, I'm not asking "what is the best ROM", as I saw that is forbidden here.
I am asking: if I wanted the phone to run smoothly, what way should I go about it? Should I root it again and go Cyanogenmod? Should I look into other possibilities? Would I get a better result just going stock and using gapps and other apps that remove bloatware instead?
If anyone has got this phone to a good standard please just let me know how you did it and I'll be super grateful.
There are so many ways to go about it I honestly have no idea where to start with
Up, any recommendations at all?
