New to development - General Questions and Answers

Here's my question. I want to start with an app or two, but ultimately want to make it to roms, themes, etc. My computer however is a bit on the low end. 1ghz dual core, 1gb ram. Decent storage though 250gb. Is this not enough, sufficient, or great. Thanks in advance
Posted from my 1.34ghz, Infected, Themed Out, Lightningbolt.

i have no idea abut roms as you might need to compile stuff for it, but for apps anything will suite if you don't rely on the emulated android devices and just test on your phone

[Q] alternative OS's on feature phones

Hi, does anyone know if it is possible to load an alternative OS like android on a feature phone? by this I mean phones that have an integrated processor, not like a cortex or a qualcomm one that you can easily find it's clock in the phone's spec sheet. I've been having a terrible time trying to figure this out, and having no results.
I also know that for some phones, this is possible, but they must have some sort of a capable processor and a considerable amount of ram and rom. However, my phone's pretty limited in those terms, but I still think it might be able to load an alternative OS.
BTW my mobile is a samsung s5600
thanks.
I think it is a Samsung S5600 is impossible. because it is just a telephone. In the phone is quite different RAM modules and CPU, which is much weaker and easier.
Sorry for my bad english
no problem, I understood
I still think that with an old android firmware (like 1.5 or 1.6), the phone might be able to withstand it, as they don't require too much ram or a fast CPU. as for rom space, I have no idea...
I really hope to get a dev interested
2.2 requires least ram but would need alot more work with the kernal to port over
yeah, I've heard that somewhere around.
do you know what about v1.6?
P.S.: btw i just found out this phone has an MSM6280 chipset which has in itself an ARM926EJ-S processor
And then there's the fact that someone would have to write drivers for the chipset, graphics, sound, and everything else that the OS is meant to talk to...
Isn't that all integrated in the chipset itself? I mean, wouldn't it just need the chipset driver only in that case?
anyway, the question still remains though. is it really possible or definately not?
Thanks

[Q] upgrading ram

Hi everyone,
I have been reading on these forums and it seems like the developers have done a very nice job with custom roms(got to love opensource community).
I got a g-tablet and was wondering if it is possible upgrade the ram in the tablet. Let me know if anyone has opened there tablet up and have looked at the hardware inside and maybe post couple of pics of the layout of the hardware.
-R
Here you go.
This thread is a good place to start:
http://forum.xda-developers.com/showthread.php?t=842354&highlight=screen+replacement
Kind of a repost; you just needed a ***bump***
http://forum.xda-developers.com/showthread.php?p=12108775
Anyway... Yes it is possible.
From what i have heard, g tab got two slots of ram and just used one with the 512kb. The problem here, like i posted 5 minutes ago, is that current roms dont support more ram than 512kb. Maybe with honeycomb release and its requirements we finally get the support for extra ram in our devices.
Cheer for the mods and lets wait a little longer for the honeycream AOSP and a port for g tablet.
It's not two slots of ram it's more like the x-box ram upgrade.
so does anyone have pics of what the ram actually looks like? And is it possible to purchase from the market?

It is *NOT* possible to upgrade the ram, period, end of story.
(yes, it's possible, but if you have to ask, you can't do it. extreme soldering skill required)

[Q] 1GB vs 2GB RAM on Android 4.0

There has been a lot of internet buzz lately around new 2GB phones coming out, most specifically the LG Optimus LTE2 and the Galaxy S3. I am looking to get a new phone, but the one that has caught my eye is the Xperia GX with Sony's new CMOS sensor.
I was wondering, how is the performance of Android 4.0 with only 1GB RAM, and would the performance increase of 2GB be a significant enough difference to want one of the Korean phones? Does anyone with a current 1GB phone have any issues with performance?
I believe all of the above mentioned phones use the new Snapdragon S4 processor.
Thank you!
I think for now 2GB of RAM is a bit of a overkill, for now, unless you're running fifty apps at once. I think 1GB is plenty enough. I myself own a Galaxy Nexus and it has 1GB of RAM. It ran smoothly even with like a few apps running in the background. Really, if you wanted to run fifty apps in the background, it will kill your battery, so I guess thats the trade off with 2GB RAM.

I don't think has talking about a nexus phone, when buying let's say an HTC evo 4G lte or galaxy3. You see left with very little ram if they were both1GB. My LTEvo is left with only 200 to 150 mb's ram left, but that's with every app I have running. Still when I'm web surfing the web sites easily ready threw the 200 mb's & more so sometimes the browser closes on me all on it's to refresh the memory I'm guessing. So yes I believe the fact that we now use higher resolution screens meaning higher resolution slings & launchers not to mention games, imo we need more RAM, not an extra gig but at least 400 mb's free. That way the launcher on the evo doesn't have to refresh everytime *really about once a week* but the 2 GB's the galaxy had is overkill but at least you won't have any of the referring the RAM every one in a while. Also to be noted in every benchmark between the galaxy3 & ltevo, the evo win's, surprisingly even in the memory I/O! In antutu benchmark & in quadrant the gs3 scores about 4780 while the ltevo scores 5000 to 5300, I peonally scored 545x... So I don't know if SG3 isusing given 2 GB's of slower ram or LTEvo is using faster RAM but it still not bring enough, all in all I will change my LTEvo do to the RAM issue that can be fixed with a simple update.
It's android or it's Windows 7 ultimate?? LOL
1 GB is just perfect.
My pc has 2.13 GHz cpu single core and 2GB ram and runs windows 7, my brother's htc one x has 1.5 ghz quad core cpu and 1gb ram for run android 4.0!
that's incredible
Android does NOT need 2gb of ram. My Galaxy Nexus runs amazing on 1gb of ram, and my Xperia Play ran ICS pretty good and it only had 512mb of ram. Right now a phone having 2gb of ram is just a marketing gimick. I can't see any of the Android releases in the near future needing 2gb of ram to be smooth. In fact Jellybean runs smoother than ICS on the same hardware, so it's getting more efficient, not less.
1GB is GOOD & 2GB is ... :good:
In theory, 1GB of RAM is lots. But I have the HTC One X (North American version) which has 1GB of RAM, and it suffers from crippled multitasking (just search Google if interested). Nobody seems to know for sure, but the general consensus on the root cause is that the HTC Sense software is a RAM hog, and therefore HTC had to modify Android to aggressively kill background apps in order to ensure that Sense performs well. I suspect that had they installed 2GB of RAM, like the Samsung Galaxy S3, the multitasking issue would not have occurred.
I have since installed an unofficial alpha build of Cyanogenmod9 on my device and it multitasks like a dream. So if you're buying an Android phone without a whole lot of bloatware, like a Galaxy Nexus, 1GB should be a lot. But if you're eyeing the HTC One X, you may want to wait for a 2GB model to come out
in future you need 2gb of memory.....
many apps and games improvement in the future......now 1gb it's still enough but in the future?? :laugh:
The more the merrier.; )
2gb is just too much for android, 1gb already runs smoothly, hell even my galaxy s1 with 512mb can run ics smoothly (true story). i think they are trowing 2gb just for people to think it's gonna be faster and smoother but that isn't the case here, though it's not going to hurt if you go for 2gb, it is just that it wont make a real difference. :laugh:
Confused, frustrated, and abandoning the platform if...
I can't find the bottleneck and get snappy performance.
I'm on a Galaxy Nexus on V. The problem is (and I'm really not looking for business advice - I'm spread too thin for major overhaul) I can't delete my SMS because, many times, it may be the ONLY reference we have for a discussion I had with a customer of what they need(ed), what I charged, when the job was completed. I realize this isn't ideal, but it's (for now) a reality.
I have a HUGE DB of SMS... over 5000. I don't install many apps... of course, I have my gmail account sync'd.
One of my slow-downs was using google-voice... however, even with it removed, it's choppy. Whether moving between home screens, loading my SMS, getting keyboard input on an SMS to respond (which sometimes takes 10 seconds to start recording keystrokes).
I know that if I deleted everything and only had a sparse amount of data (primarily SMS) it'd be faster. And for good reason... managing a DB of texts seems like a lot of data to organize. And that... I assume is controlled by RAM.
And before anyone jumps to conclusions, bare in mind, I own a tech company. There's nothing broken on the phone. It runs the same as EVERY android device I've owned. Pretty fast (generation specific) at first, then, slows down... by month 3, I dislike the phone.
Yes, each generation gets successively LESS painful -- but I have an EXTREMELY fast paced life. I always have 2-6 people waiting for my attention throughout the day... every second counts. And every delay is annoying.
Is this just fatally-flawed-android for you? Unable to deal with a large(ish) DB..? Is this a RAM issue? Is this energy saving issue? I'm currently waiting for the iPhone 5 for a larger screen. If it has one... I'm probably jumping ship. I've exhausted my attempts with android... if either RAM or JB 4.1 doesn't fix this... I give up. I need my messages.
Suggestions? Am I overlooking anything?
THanks
Well more RAM can't hurt you, but it really after all depends on the device you're getting. These days I reckon as long as it isn't below 1GB RAM for a mobile device, then it's ok. As a matter of fact that's great
If I may suggest a mobile device for you to have a good look at, this would be the Samsung Galaxy Nexus. It's google's flagship phone, it's great, mostly gets the new updates first and is very reliable and clean. It isn't hard to root at all also, and is very true to its core, with google supporting it more than any other device. I currently have a Nexus S, the one that came before it. It's great, but would really need a bump in speed, I can see myself getting a new phone in 6 months, maybe when google come out with a new mobile device.
cheers, and good luck on finding a new phone.
That IS the phone I have.
Thanks,
Truman
It sounds like you have the same problems as iphone users at http://michaelhyatt.com/speed-up-iphone.html in which case switching to iphone probably won't help.
You could use a free app to backup your texts, "sms to text" is one which could help and you can save all or selected texts to txt or csv formats which would also mean you could search quicker when needed or transfer backups to a pc.
It seems it is a smartphone issue as opposed to model specific, based on a lot of googling not my personal experience though, but backing up would allow you to access the data as needed on other platforms.

[Q] Highest Performance Android?

So I find it very hard to find raw information. Much less the time to read through all the hardware specs.... so here is what I am looking for, Most of what I read points to Galaxy S4, HTC One, Sony ZD and Nexus 5. But everything I read is so D*** biased.... its hard to get factual advice. I am looking at getting a new phone, the software that comes with it is garbage (will be rooted, and all my own os features installed ie launcher etc etc etc, I can do anything I want to through tasker, etc) i am looking for phone with biggest batter, fastest processor, most ram, largest internal memory and I really hope an sd card slot (one thing I could never get over with nexus devices) now it doesnt have to be one of the above listed models they were just examples...
So guys whats the android with highest hardware capabilities out there? Also kind of want a device like moto-x that has seperate chip for always listening..

Build rig

Hey all. Im thinkin about putting together a computer to build roms. I have an idea of what i want.
Now i was wondering if i could get some ideas from devs or home builders with experience.
Now this is what id like to build
http://pcpartpicker.com/p/XpwKK8
Now im wondering. Would an i7 really be all that much better at building roms than a amd fx 8 core?
I would like to play some games also but they dont have to be perfect.
Just looking for opinions
From my past experience, you will need lots of RAM to complete builds quickly.
You might want to consider increasing your current 8gb to at least 16gb or even 32gb. And using a SSD will save you a lot of time as well, but I don't know how much you're willing to spend.
First of all, I would recommend with the i7 because in my experience Intel has always worked much more smoothly and easily with Linux. And like the guy above me mentioned lots of ram and an ssd would help you greatly.

Well I think this setup is a good start then. I definitely add more ram and a ssd

What distro of Linux do you plan on using?
You should post your budget so we know what you can buy.
i7 over amd fx...not that i hate amd products,am a big fan except for its CPU that overheat a little bit

Looks solid. Just get 16 GB of RAM if you can. You won't need the GTX 760 to build android from source; but I think you choose that part to do some gaming instead.
You might want a SSD as your boot drive. Using a SSD to store and compile android from source may not be the best idea as the entire process needs quite a bit of space. But hey, that's up to you to decide.
And uh for Linux distro to use, some suggestions are Elementary OS or Linux Mint. Recent Ubuntu (14.04) seems very strange to use. Then again, there's a lot of distros to choose from, so give them a try down the line.
Sorry for the late response, but thanks for the replies.
Right now im using xubuntu 14.04.
Im not very experienced but im learnin. Just learned how to build slim from source and im typing on the rom i built right now, its stock slim. Id like to learn how to cherry pic stuff so i can make it my own, then maybe one day be able to write my own source code.
So, I guess id use xubuntu, has worked so far. Unless theres a better suggestion or reason to use something ells.
I plan to piece this rig together over a month or two or however long it takes. I guess my budget is sorta endless, $1,000 is more than i would like to spend, but id like to have a pretty darn good rig. It doesnt have to be the absolute fastest computer in the world, but id like to be up there. Ive heard lots of good things about the gpu and cpu i picked and kinda set on it. Id maybe change to a cheaper i5 equivalent, i heard the i7 isnt a huge difference in gaming as most games dont utilize HT. But i assume it would help build roms.
So anyway, im ok with spending $800-$1,000 to have a great rig to start. But I always plan on adding to it. This list is just to get me going, first id maybe buy the MB, then the cpu, then the case, then maybe a 8gb stick of ram and a hdd etc.
In the end, id like to have at least 16gb of ram, dunno if more would make a difference
And have maybe 2 250gb ssd, one with windows 7 installed and the other with linux installed (dont know if thats possible) then 2 1tb 64mb hd's and another gpu, which i believe the mb i picked is not good for dual gpu's so i might need to find a different mb
Edit: well, now that i think about it. 2 250's might be over kill, maybe 2 80's or 64's just for the os
Anybody got any good suggestion s on ssd's? I heard they dont last very long without some tweaking. But, what are some dependable brands?
Create multiple partitions and dual boot lol
&& Yes you can put multiple SSD's with different OS on them. Ideally you want the OS on the SSD because they're extremely fast. Just get a high RPM HDD for storage tbh. I'm pretty sure mods will delete my link if I post one, so just Google newegg and see what they have to offer
