about the hardware - Android Software/Hacking General [Developers Only]

hi guys:
android is very popular nowadays,every manufacturer is makeing awesome android phone or tablet。so i was thinking what‘s the different, what kind of mother bord dose they use,is there a different or they are using a some motherbord and just change the cpu or what. i was confused。
For example, i want to make a tablet myself, i need a motherbord and android system right? the system is free ,but where my supposed to get the motherbord,and how my supposed to run the system on my homemade hardware.
please help me!!!!!!!

android is an OS, any hardware that can understand the OS of android will do.
even phone with Windows OS and hardware, some people are able to port Android also.
There is something to do with the processor that is supported with android mostly ARM.
for your peace of mind read this.

thanx it helps a lot

[Q] [N00b] Nokia N8 with android why not?

Hey,
Why is there no android version for the N8?
Could anyone create it? There is enough animo for it.
If i read some forums I see that some people want it. Why not?
Also it has the best mobile camera in the world.
If someone can run android on it it would be the best device ever. (I think)
I could find an answer on this forum. But I think this is already changed.
(That there isn't enough animo for it. But there is!)
I'm also a newb in this world. But I like android and the compatibility that the most devices already have with it.

I dont know if its that simple. I dont rly know if the android suitable for N8, anyway would be nice to have it (even though that i have HD2, which i think that is much better than N8.) If its possible, my friends will have android too! xD
indeed!
I think an android developer must buy an n8.. that he can see it's a wonderfull device.
And then create android for it.
Not all phones are like hd2, where you can have different os
Sent from HTC HD2 with Android
Not all people wants a HD2
you are not alone my friend!
I too wish the N8 had Android.
It is a much better device than the HD2, screen size isn't everything.

anything is possible, it just takes time.
and in the HD2's favor, it had hardware that was common across different platforms.
plus a big userbase
Isnt the N8 nokia soft based on Debian? couldn't drivers be ported my friend has this device and yes the camera is amazing on it
I thougt it was only meego and maemo wich is debian based?
i was thinking to get a nokia n8 untill ive found out that nokia had very low quality development for that new symbian version, and that they moved torwards windows mobile... i never liked windows mobile and since they were not going for android i said whats the point, on paper the nokia n8 is amazing, but it has some problems aswell, for example the cpu is only 625mhz, while its arguably enough to run android, im not entirely sure it has all the instruction sets compatible with it, emulation is out of the question too, the android code would have to be natively changed to work for it, and then there had to be the matter of games, they also had to be coded properly for that specific gpu,cpu and sound chip, accelerometer and so on.
So thats why ppl dont usually port phones to android, its a mess to code and most of the drivers they have to code them from scratch.

The CPU is official build for 750mhz. So it can run faster.. Also i heard that the new version of android (3.0?) has hardware acceleration for the UI. So the GPU can be used for it.
cpu for android need nore juice and ram.
battery life will be hunger for more to join android.
nokia seem battery effective device.low power consumption

Why?
The HTC ChaCha and Salsa has a 600 mhz processor... And still Android runs on it.
Indeed the ram is littlebit low 256 mb...
Chacha is 800Mhz, 512 of ram..
yeah i wish that someone would find a way to port android to n8 i recently got one and dont like symbian os, any way i'll keep on searching if no luck, guess i have to get an android phone
Edit: forgot to say i had a sony ericsson x8 which had 600 Mhz processor and 256mb ram and i was even able to run android 4.0 on it dunno why n8 would not run on this device
The question is why port android to N8? The N8 is a wonderful device as is. If you have an N8 you probably bought it for it's camera prowess. Bonus: you get a very long battery life (compared to droids). Now if you want to port android on it then it will become power hungry and will be full of glitches since it has poor dev support. Also, you wouldn't want a slow droid. 600mhz for a droid is quite slow, and as stated, the RAM is low. You're better off buying an affordable Galaxy Y. Believe me it's quite fast, if you can live with it's low res screen.
Cheers,
Cezar

it's not possible to port Android or any other OS to symbian phones because of locked bootloaders by Nokia
Nokia n9 is running meego OS which is with unlocked bootloaders and that's why this phone can have dual boot or just one OS like Android 4.x.x ICS
I want it too
I have an Nokia N8 too and i would love to run android on it.
So if there is any way to install android on it....
I also have nokia n8, it was really a great phone,hi quality build, superb. And I fine with symbian^3 but what bothering me was that the nokia apps store is getting useless. I need BBM and can't find any.

[Q] Android noob, Generic device, A few questions?

First let me introduce myself. The name is Darcy and I have been casually using linux and other *nix OS for about a decade. I am in school working on a programing degree ATM, and am a pretty quick study. Anyways, I without much research bought my wife a generic 7" tablet running android 1.6. I know what processor it has and Im hoping that leads me to a place to start. Ok so the device is a "Kasser Net'sGo" we didnt realize that its just a china pad with another companys name on it when we ordered it. So most of the apps dont run correctly, and in general the device sucks(on a software level the HW is fine although generic).
Anyways it apears that i can get into recovery mode to flash if i had no other choices. But since there are no official roms im hoping to find a build thats based on the same CPU or similar hardware to find a starting point. Its running the Marvell Aspen 800mhz chip and standard ddr2. Sadly thats all we have been able to find out about this device.
I have compiled custom builds for linux before, and i have now purchased a Gtab so i have a less garbage device to test some things on(i have allready flashed 2 different roms and fooled with a bunch of the settings). But we would realy like to do something with this other tablet. So if anyone can point me in the direction of some info on how to do android builds or a repository of chipset drivers and such that might help me that would be greatly appreciated.

[Q] LG BL40 Chocolate

Hi, i bought this phone an lg bl40 new from 100 euros, but now i´m not very happy with OS developed by LG, so i was wondering if is possible to install new OS, i mean from android or from windows. If yes, could you people help me step by step what to do? Or there is nothing to do with this cell phone...
I do not believe so, because it runs S-Class operating system, a completely different operating system than Android. Also, after searching, no one has brought up a way to put on a new operating system that I could find. Sorry though!
I am afraid there is nothing to do with this cell phone.

[Q] Why Windows Os can run on allmost all Pcs and why Android roms can not?

Noob question, i dont understand why Windows os can run on allmost all computers and why Android roms does not ?
Because windows is a computer OS and Android is a mobile Os
Sent from Arkham
I mean why Android roms for example Cynaogenmode 9 for Samsung cant go also on HTC if im not wrong, but windows can run on all computer.. i just dont understand why ??, I'm just started new flashing roms ecc. I was used to the pc that was so simple.

I dinnt understand well, butt why they cant do this also on smarphones, for example on the computer you got the Bios and if somthing goes wrong with your OS you can always go to the bios ecc. But why they dont do the same on phones ?
Windows : An OS : Runs on PCs
Android : Also an OS : Runs on smart phones
Some basic common sense..
So this question is pointless

Im started new flashing roms ecc. i still dont have much experience, first i thought that the Clockworkmode ecc was a smartphone Bios but then on the internet i read about many people briking phones by flashing wrong roms ecc. when i firs was thinking that you could always recover from Cwm like on the computer Bios but it was'n like this. So i was thinking, why ? there isnt something like a bios on the android phones ? so you can always recover if something goes wrong ?
actually this is an excellent question......whats so hard abt having a mothwrboard that boots up in bios....nad then it allows u to install whatever system u want. after that u get to download drivers for ur hardware from some system driver pool....basically most phones have the closely the same hardware in our days especially when u can make use of sd cards as an external source like dvds nd cds.....the question is why r smartphones os's built in a different way and what stops them from being composed this way? isnt it more logical?

Cwm=1/2bios. Windows is open for all part combination with drivers. But android or other mobile os are cant support different drivers. Companies select os and other parts and develop correct drivers for parts and os. Mobile devices have special drivers. But pcs are have open for all drivers.
This text hard for me because i m turk.
This is a fantastic question! Essentially what has happened over the years is chip makers have designed their hardware around the windows os, and they have been able to do so because the windows os is a boxed software that, for the most part, cannot be changed. The Android os on the other hand is open sourced and can be tweaked 10 ways to Sunday, which is why most of us prefer it over ios or win mobile. The downside (kind of) is that the phones and tablets are specifically designed around the os and the os around the device. So in order to upgrade the os either the manufacturer (Samsung, Motorola etc) has to develop one or one of the brilliant coders out there has to work on developing one from the source code when it is released by Google. Hope this helps.

Great question, Many answers definitely.
Android OS are built around the phones, around specific devices.
For example:
GS3 and Note 2 are built on somewhat the same,
so odds are specific roms are ported to GS3 ( Serenity 1.2)
but GS3 and HTC One X are two totally different companies with two different builds of components so you'd not have a port from a Note 2 to One X.
It's logic once you look into the components of a phone and how they're built VS how computers are built and such.
GPU, CPU, Storage, etc on a PC are all parted,where-as on a phone they're soldiered onto one main board.

Now i understand, thanks i was thinking it would be possible to build phones with a Bios and basic drivers preinstalled in the motherboard, just to run android, and then from there find the driver updates ecc for its own device. That would be much easier for all of us to flash roms, kernels ecc without the risk of briking divices, and also now a days the smartphones are almost like real computers ecc. I think if you got an HTC + 1.7 Ghz x 4 you wouldn't like stop receiving updates for your stock or custom rom because its still a good piece of hardware, and also even if i would got to pay 20 $ for an Android upgrade i wouldn't mind, i think an something thing like a bios in a phone will give a piece of mind for everyone, and it would be much easier.

But for example if HTC,Samsung and all manufacturers . install on there mother board a bios + basic drivers for input output ecc. and to separate Android from it. So you could then have a one Android for all. And devs could focus mainly to the functionality and less to the compatibility. It would be fantastic :thumbup:

As simple answer: Most android devices use a lot of closed source/specification hardware.
Plus locked/partially locked bootloader
In windows (and linux too) kernel there is a lot of closed blobs which work fine on pc because they were precompiled under x86 arch, but there's no use for them on our arm devices.
If we had open specifications and hardware device, we wouldn't have any trouble getting OS in there(that's what china manufacturer do)
As usual - the only issue is copyright.

Android and windows have more in common then anyone is letting on.
Wi ndows is closed source some other android is closed. Some of is is open.
Even though most of yours computers have windows dosnt mean that you can take the hard drive from one computer and expect for the Oscar to boot while in another computer. They all have drivers that are gding to be different.
Computers have biOs because of many different reasons. Computers are versatile smartphones are a relatively specialsized piece of equipment.
The question you ask has an answer but I think the same question can be asked aboout the differences between a couch and a chair. Someone just thought of a way to do somthing and it became the standard. Again computers freeway more advanced then smartphones. How many boot devices can you have on a smart phone? MAybe 2. Computers can have many hdds, many optical, many usb devices, many network boots...etc etc

So in chinese phones its possible to do this ? For example on my computer i have tried windows, ubuntu ecc all on the same hardware. so in chinese phone its possible to boot Android or Windows 8 mobile on the same hardware ? i dont understand now, its is possible but manufactures dont do it or its a tecnical problem. ?

No it doesn't matter. It is alot of closed source stuff in windows. Not to mention MS would C&D anyone that may even try. Even the new windows 8 32 bit pc systems have a locked bootloader so you can't change the OS

Im a little confused because i dont have any experience in how software and hardware runs together even i would like to learn it , all i know is that i cant put an AMD CPU on a Intel compatible motherboard, but an AMD and intel computers can run both on windows, Ubuntu, ecc. So now i understand that almost all Smartphones have diffrent hardware, but they can not all run on a one Android version, but Android needs to be customized to the hardware. Am i wright ? Do you think if manufactures produce there hardware to fit in a one Android version, and devs focus in a one Android version, and also roms could be compatible for all devices, if im not wrong. Because what i sow now is that many devs work more on compatibility, and if it was the other way they could realy focus on the functionality of Roms ecc. I'm still new in this world and i have a lot of things to learn, so im asking you guys, because you know more than me, so i could learn somthing from you.
Biggest problem of mobile devices is lack of good boot "catcher", as in BIOS, whom would allow custom kernel load.
Despite being binary compable(not always), the way android is being started differs.
The best we are getting is unlocked BL, but never open one.
Also, you have mentioned china devices.
On some chinese smartphones fully open bootloader is present, that's why it is possible to launch ubuntu and even windows(on atom tablets).

Possibility of dual booting android and windows xp on our device

hi there the possibilities for our device is endless it is definitely possible for our to dual boot windows xp and android with our device maybe we could make it run on our armv7 processor if someone is able to do this project i can help

Windows XP ? Impossible not going to happen, not worth the effort.
Windows 8 RT, Possible, not worth the effort..
Recommendation: If you need or really want to have both, buy a Lenovo or Dell WIndows 8.1 tablet for less than $200 and you will be much happier.
Development Level: Lazy N00b

So you want to Dualboot Windows XP and Android ?
May I know which device you've ?
One thing is sure, YOU CANT DO THAT ON A TAB
Many members including myself got idea of running Windows 8 x86 on Tab 3 10.1 since it have a 32Bits kernel, but nothing happened.
Never
I think this will never happen, because of mainly two things:
1. No drivers available, you would have to write them all cause there are no preconfigured ones.
2. Windows is closed source.
You would need to be a Dev at Samsung, otherwise you will never have an insight into the specific hardware of those devices. Samsung but also Intel (in case of the 10.1) don't publish most of their documents.
No.
hey,
if you want to really understand what windows xp will be like run it through an emulator.
now, don't get me wrong, i loved windows xp, hated everything before it hated everything after it.
apple is bull****.
Linux is beautiful.
Android is commerce riddled slop and needs to die a horrible flamey cinematic death accompanied by bad lighting
and a third rate orchestra trying to play anything while being fed into the woodchipper of your choice.
anyway the point outside of my ranting is, maybe yes but seriously no.
as soon as i figure out how to get a decent lightweight linux distro running on this thing then i might be able to
get wine going. better to get a windows-able tablet pc and dual-boot android x86.
