Thanks for the useful info and nice forum(an Introduction)

I am a new owner of an Acer a100(16GB) (currently 1.018.05_COM_GEN2) Android v3.2 and wanted to introduce my self and offer my assistance with A100 development in any way.
I'm an Android noob, but I use Linux and have done some shell scripting(Perl, Bash, Sed, Awk, a little javascript), and I am in the process of learning Java. I have also modded other devices before like PS2, PSP. So I am looking forward to learning more about Android and since I have an a100 this seems like a good place to spend some time.
So far I have just rooted my device via the Terminal Emulator method(I do have Eclipse IDE with Android SDK, ADT installed and working and should be setup help compile), got superuser, busybox, titanium, Avast installed. I also made a backup of my recovery image with dd in a shell, and did the AND to WIN hex edit(w/ Bless) of libflashplayer.so for Flash 11 so I can watch hulu, etc via Dolfin HD. I also made a Bash(run via Terminal IDE) script to re-apply the modified file after a shutdown which for now I have installed into /data/data/com.spartacusrex.spartacuside/files/bin (aka: ~/bin).
I will probably post my hulu script and lib file with some instructions later. It's basic but effective script that does some file checks and error correcting before it catenates the source file and redirects to destination. Later I may add a few more checks like making sure its running as superuser, and some post file mod checks.
Im still trying to figure out what else we can do, and how to do various things within Android at this point. So far its a fun little setup.
I wanted to say THANKS to everyone here. This place is a great resource. Special thanks to everyone that has been working on the Development end. I look forward to trying to make my self useful.
Welcome Hope you enjoy this device as much as I do.
As far as helping development, you should really check out the bypassing the bootloader thread in this forum, that's where the brainstorming is taking place atm.
Yes, we are *trying* to bypass the bootloader somehow, Crossix is getting a working kernal going while others are looking into methods of applying a work around. Your help will be much appreciated. Welcome to the Forums, and as stated above, the A100 is a great device that has a lot going for it if we can get some work done on it.

Yep I have been reading it and looking around trying to get an idea of what the typical solutions/workarounds are used on other Android devices.
I don't think I have access yet to the developer area yet.
Welcome to the a100 forums, it's always nice to have another dev working on this thing!
Development forums require 10 posts to be able to use them, so just remain active in general/QA and you'll have access in no time.
Congrats on your New Tab

petition for jiayu to publish repositories

Dear Jiayu S3 hardware/software development department,
First of all, thanks for making the marvelous Jiayu S3 device and
providing software updates.
There is an enthusiastic XDA community dedicated to the Jiayu S3 with
'tag' jiayu-s3 : http://forum.xda-developers.com/t/jiayu-s3
This thread named 'petition for jiayu to publish repositories' is
created to ask you if you can make an agreement with Jiayu
management to make source code repository for kernel source available,
and, to ask you if you can also make the necessary vendor and device
repositories available for building firmware (especially custom
firmware such as e.g. cyanogenmod and aosp).
Please, if these repositories can be made available, also include
necessary patches and instructions to build kernel and firmware
e.g. cyanogenmod and aosp.
Other vendors have contributed to better linux kernel and android
firmware that way and we would be proud if we can say Jiayu does the
same. Especially for the new 64 bit architecture starting with
Lollipop.
Looking forward to positive response.
It seems this thread has outlived its usefulness, as I just deleted 25 garbage posts by forum users that should know better than to spam a thread. Be glad I don't have the time or patience to dole out infractions to every person that posted here. On that note........

Currently on Oreo, December 1st patch

Hey team,
I'm very new to working with smart phone bootloaders and flashing different ROM's. Currently I have only ever played with ADB a little bit, have never come close to flashing another ROM/firmware, let alone rooting.
Here's the thing, is that I've very interested in running a couple operating systems on my S7 Active, however it seems that if I am on Oreo, this process becomes much more difficult.
I come here for 2 reasons, first is that I need points to ask questions in other forums. I figure here is the best place to start on getting answers and where to look for information.
My second reason is so that I may get some help / information on how to get my S7 Active set up for using at least 2 operating systems - Regular Oreo, as well as Android's PostMarketOS. I am a new user, so I cannot post a link, however you can find it at reddit r/PostMarketOS. I am fully aware that I will likely need to build my own version of PostMarketOS. I'm not here for help with this, so much as I am here for getting help to prepare my S7 Active for this process.
So, I suppose to start, my questions are as follows:
1. Am I stuck with Oreo?
2. While I have unlocked OEM in developer settings, I feel that there's more to unlocking the bootloader - is there information for Oreo on how to do this?
3.I understand that there is root for Android N (7.0), however I have read that you cannot downgrade to (7.0). Furthermore, I am not sure if this would even be necessary.
To give a bit more information, to create the PostMarketOS for Android, it must be created using Linux, and I have a link to post, however I am a new user, the guide for creating PostMarketOS is on the sidebar of Reddit.
Hopefully I can get some help, but I would be happy with just some resources on where to go about starting/finding information. I'm a total noob in this regard, but I am a quick learner and motivated to get my S7 Active to not run so laggy... Plus it would be fun to use 2 operating systems
If you need any other information, I'm happy to find and give it.

What works it usually takes to make LineageOS support new device?

Like other Android OS, LIneageOS need extra work to make it support certain model of device.
Is there any detailed list about what works should be done to make LineageOS working on new device.
If the official ROM of this new device is provided, is there any technique to utilize the component(drivers) from the official ROM and import them to LineageOS?
Is there any detailed Tutorial/Documentation or Textbook to teach newbies about how to porting the LineageOS (Android) to new device?
im interested in it is well ..
i whant to contribute to develop new device ..

Which version of Android (GSI) can I run on a device with VNDK 27.0?

My plan is to flash a GSI image (LineageOS) for android 9. Specifically the following
- https://github.com/LineageOS/android/tree/lineage-16.0
- https://github.com/AndyCGYan/lineage_build_unified/tree/lineage-16.0
Is there a chance of getting this to run on my device? Please see the attached file for the output of the Treble Info app.
I cannot find any information about the impact of VNDK version 27.0 so any help is much appreciated.

I have the same issue, only thing I could find out, some features not gonna work, (who know what), if you install a newer vndk you wont be able to return to an older one. Be honest, Project Treble is made for seamlessly update phones, but it is a mess, versions, vndks, legacy phones, A-B-A/B images, etc. it doesnt do what it meant to do.
The XDA forum was a good place to ask questions like this, it was, still remember to get answer about my 10 years old phone, however things really changed over the years. Members change their phones on montly basis, so dont expect any professional answer.
