[Q] Help needed on building custom Android for a new Tablet - General Questions and Answers

Hi,
Right now, I am looking into building custom Android OS. Here is my constraints,
-- It is a custom build for a new Android tablet
-- It should launch our own app when the OS boots. This app will be main entry to the tablet. Need to lock down/remove all the other apps and launcher screens
-- Device drivers are need to be changed while building according to the hardware
-- There is no constraint on which version of Android need to be used
Hardware details of the tablet:
1.2Ghz Cortex A9 processor,
a 7” display of 1024x600 resolution
comes with Android 4.2
Do I need to look for building a custom ROM or with a new design of Android launcher app I can enable these? For installing new device driver I hope I need root access. I have searched a lot of tutorials on all the topics. Can anyone suggest me where should I start with according to my needs?
Let me know if I need to provide any more details.
Thanks!

[Q] ROM for SMDKV210

Hi ppl,
I have a tablet with Android 2.2. I think that it´s a Sinor M8 but I´m not sure (How can I see it?). The problem is that the OS doesn´t work well, for example, Google tells me that it´s an unknow device. My question is how can I reinstall Android 2.2 or higher (I prefer Honeycomb). Is there any ROM for this device or an tutorial of how can I compile the Android source code for this device. The device has an ARMv7 Processor rev2 (v7l) and 512 MB. Is it a good decision to compile it?
Thanks,
Gabriel
I saw that my device has SEC-SMDKV210 8in Android 2.2 CortexTM-A8 512MB 1Ghz HDMI. Is there any ROM for this hardware. I saw that many devices have SMDKV210.

Compiling Android for a Device without sources (Zenithink Tablet)

Hey, so last year I bought a China-Tablet called Zenithink C91, it seemed like a good choice back then.
However, the software on it is rubbish. The manufacturer didn't even bother to change anything from the reference software for the hardware platform, did no optimization whatsoever. For example the build.prop is a complete mess with dozens of duplicate lines and references to the reference platform from AMlogic. All the stock firmwares have phone functionality enabled, even though there is no gsm module, showing an empty signal indicator all the time. Or the shipped ICS with gingerbread gapps and so on. The Tablet is just not usable in this state because the software sucks so much, and they do not answer any questions or take advice. Therefore, no sources.
However, I think the Tablet could be much more useful, because it has a decent cortex a9 processor which runs at 1ghz, and a mali 300 gpu.
So much for the situation.
So for a long time I thought about trying to compile a new rom for it, to make it actually work like it should, but I cant find any advice which would help me, because all tutorials that I find require me to use devtrees for devices that already exist. But how would I go to create Android for a device which has none?. I could probably extract most drivers from the latest ICS build. How compatible are they with JB?
On a side note, I wanted trying to Port CWM recovery, does anyone have a pointer where to start?
Thanks and I hope I did not post in the wrong section.
I actually think that there is a source available for your tablet. Check out Slatedroid, as it's a forum dedicated to chinese tablets.
The problem atm is the new version of the amlogic's platform for which they haven't released sources yet.
Oh, and tutorial for Clockwork recovery:

Thanks for your reply, especially for the link concerning cwm.
I am aware of the slatedroid forum, and a user there, too. Zenithink did not publish any sources, I am very sure sadly.

Zenithink maybe didn't, but you can find amlogic sources (the chip/platform manufacturer) here:
http://openlinux.amlogic.com/wiki/index.php/Arm/Android/2.Getting_the_Source_Code
edit: that is if they are using that as a platform ofc, if they're not well from what I see on slate you're limited to modifying stock roms, same as we on elf/aurora ii devices
Yeah, the stock sources are there, but ZT modified them and does not release the changes. No chance then, I guess? Anybody know if there is a chance for JB based on the ICS rom?

[Completed] [Q] Develop Custom ROM & Recovery for Logic X3

I would like to develop custom roms and recoveries for the Logic X3. Unfortunately, this device is quite unknown so I can't find any drivers for it
It is currently on Android KitKat 4.4.2, and with its limited internal memory I am limited to the number of apps I can install. I have tried EVERY app/mod this forum and Google has to offer. None works.
I really would like to begin by making a custom recovery for it. Attached is a screenshot of some of its features.
Anyone who can help with this is greatly appreciated.
Hello there
You will find a lot of information in the XDA University pages, especially this one: Getting Started: Building Android From Source
There are lots of resources throughout the XDA forum, for instance this one: [UltimateGUIDE][How-to]Create your Own Custom ROM an easy way|Android Secrets -_- and this one [ GUIDE ] How to Prepare Ubuntu 14.04 LTS Trusty Tahr to Compile Android ROMs
Good luck

Building customized android for RK3288 enabled tablet

Hi Team,
I am new to android and its family so need help in most of the steps going forward.
I have a rockchip 3288 based android devices which is connected to couple servo motors which is provided by a chinese company.
The booting, launcher and other features are all in chinese and we are finding it difficult to change the language to english. The reason, once we change the language to english the device will stop working throwing an error as bootlauncher has stopped.
Now the question is how do we create our own boot.img file and other android related features as we would like to override the existing loader provided by chinese manufacturer.
The ultimate goal we would like to achieve is to make the android tablet into kiosk mode.
Please do help and looking forward to the details.

Best tablet for custom android development?

Hi,
I‘m looking for a tablet as a development platform for gettting into custom android firmware development. What device (current or discontinued) is the most painless to compile a custom rom for with a current android regarding unlocking and driver support in 2021?
I‘m an electronics engineer and have worked on firmware for arm microcontrollers and did some kernel development for embedded linux (yocto) before.
I have the idea of creating an open source custom android for elderly people and small children that is pretty much locked down and has a simplified interface without cryptic messages. All settings, app installation and user support should be done from an app on another device. I think all the building blocks for this exists, I just want to put them together in one package. If you have suggestions for an existing base rom to build this on I‘d be happy to hear about it.
Cheers,
Rick
