Hi there! I was curious as to the ROM developer workflow. I'm somewhat familiar with building AOSP for x86 VMs and have done some skinning and manipulating system apk's ... but I have some other questions:
1. What distinguishes a ROM package from other zip installers, I guess since it is *nix, everything's a file and most ZIPs then just have the files changed?
2. Jokersax makes mention of doing all development on the device itself... What this workflow, just doing a lot of nandroid backups then, or just replacing things on the fly and hoping for the best?
3. What options exist for adapting system level native code, perhaps I guess I'm asking if, for instance, the camera works with Blur stock SBFs, how could one go disassembling the functionality and deriving CM9 compatible packages? Are the drivers that tightly coupled with the UI elements? That would seem impossible to maintain, and say what you want about Motorola, I couldn't imagine this to be the case.
Thanks -ap

1) You are pretty much correct....and rom can be turned into a simple one file zip or vice versa
2) He actually uses the device along with a build machine. You can do some simple stuff on the device itself, but if you're going to get into decompiling jars or apks, you will need a bot or a PC.
3) Apktool (Linux/Windows) or Android Suite (Windows) will allow you to break down the apks like you are describing. I'm sure you can make a blur apk work with CM9 (obviously app developers on the Play market do manage to make both). I'm not very familiar with Blur/CM7, as I started work on ROMs after ICS had hit, and I really didn't see much real desire to do something that wasn't forward from where my phone was.
Mainly, you can do source work, which you are most likely familiar with the process of.
I do "port" work...taking the framework, apps and some other necessary functionality-related parts and making a new rom for my device with it.
If you are interested in the process, by all means get in touch with me via PM. We are in need of some people to help with a void that has been left by our team member Spleef taking on a second job.
Thank you so much for the extensive reply. I have about a kabillion personal projects, it would be perhaps interesting to ruminate some on the metadevelopment as it were, I do notice that the Cyanogen project seems to have a lot more ability to automate their workflows, it would be cool to try and get more people into those kinds of logistics to help out... Anyway, I'm trying to remain productive, I'm a long time lurker, and I can't bring myself to post unnecessarily to even get to the 10 posts I need to provide feedback in the development forums, but I'll try
I've been really inspired with the Clojure / Java community, especially "Leiningen" and things like Jenkins for continuous integration. Could be cool to try and think at this level, perhaps like a chrooted VM or something that enthusiasts could run to assist in build CPU times, or hell I dunno, this kind of thinking is all pie in the sky and is hell to set up possibly for little gain, although I'm encouraged that Bittorrent is being used a little more here and there perhaps to offload some of the hosting costs. FWIW I have used S3 in my own projects, and for various static sites I have, I've been hard pressed to pass 30 cents a month in hosting costs on S3, but this is all low traffic stuff and there's a lot of options out there with various kinds of advantages and disadvantages.
All in all, thank you all for your continued efforts, especially going into the later part of this year when JB will mature, and the possibility of ICS drivers being integrated. You guys rock!
Hi all
I am developing an app in which I would like to allow user-generated content. Specifically, this will be a remote control application, and I would like people to be able to add custom layouts, capable of sending "events" through the app, but I am not sure how to do so.
There are a couple of ways I have been looking at. The first is using a WebView so that this content can be developed in HTML. This would be nice and easy from their point of view, but it does have it's downsides, especially where security is concerned. If I was to do this, I would want to bind a "send" Javascript interface to my app, but disallow any other Javascript (I do not, for example, want it to be able to relay the button presses to some other place). I'm not sure exactly how I could do this.
The second way I can see would be to use an XML file and build up the layout from that. Here, the only way I could see it to parse the XML file and programatically build the layout. This seems a lot of work, and I would rather avoid that.
A third way would be to import a layout purely as an image plus an XML file describing hot-spots for triggering events. This seems to have too many limitations.
The final option is to expose an interface to other apps, and allow users to build separate applications which hook in to provide these layouts. This seems a terrible approach for such a simple objective.
So, does anyone know of a simple way to do what I am after, or any comments on the options listed above? Has anyone done anything similar, or know of an open-source project which acheives something similar?
Thanks in advance
Hi all
This is my thread for an ongoing project im working on called AndroidOAP
OAP is not Owesome Android Project, lol
This is Andriod Old Age Pensioner!
But WAIT!! This may have many applications to other areas in the caring community!
Background
My mum is 75 and has early stage altzimers. I have noticed a lapes of memory, eyesight and hearing. I have also just got her a 10" rk3066 4.1 tab for xmas.
The aim of this is to help her keep in touch with family and friends (social networking), keep up to date on the weather/news (she loves it), keep her mind active (games).
Aim of Project
This project has a few aims, guided by anyone who wants to contribute. some of which are :
BASIC
- Creating a simple UI that is easy for pensioners/handicapped people to use
- Identifying simple to use apps that perform complex tasks
- Utilise the accessibility capabilities of android specifically for the users needs
- Monitor the device remotely
- Monitor the users interactions and provide alerts (IE medication, doctors apointments, etc)
EXTRA
- Create a working rom that can be installed on devices that can be given to the target audience (OAPs, disables, etc)
- Obtain ongoing support for this project
This will probably not interest most of you but anyone willing to contribute to this nobell cause will be very appreciated
Please get in touch with any ideas
Thanks for your time

If I read this correctly, you want to develop an OS based on Android, but one that is extremely simple to use? All I know is that this would be an extremely time consuming project, probably half a year at the least, because you'd have to remove tons of drawables (images and stuff that is rendered) and code, and add in many more. It would be much easier to just install a launcher with big icons, change the system font size to the largest possible, perhaps use some accessibility settings, and debloat the tablet to the max.
Has your mother ever used electronic gadgets before? I forget the saying, but it's something like you can't teach an old dog new tricks. Considering that these types of electronics didn't exist during older peoples' generations, it'll be significantly harder to get them accustomed to such things. I don't know if I'm stereotyping or not, but it may be increasingly difficult to teach her how to use Android because she has Alzheimers. I'm not saying it's not worth a try though. As long as she doesn't feel overwhelmed or frustrated, I'd say to definitely try it out for a while and see how it goes. Happy holidays and have a happy new year. I hope your gift does good for you all.

Thanks for the input dude, but, I think your over complicating things. A custom rom doesnt mean rebuilding it from the ground up! The aim is to find the most user friendly apps and the best settings and then create a rom around that. no need for new icons, etc.
Just to let you know, even though my mum is 75 she has been a nurse all her life so is well versed on using computers (hell, she brought me up and im a developer, lol). Touching icons on a screen will be no problem for her, altzimers or not. To be fair, you are stereotyping and its pretty sad
Regardless of the support I will continue with this as its a personal project that I will persue. I was just after any help I could get, not negativity.
Have a nice day

Hi @Cass1977, I see your project as a great initiative to encourage older people to use technology. Although this project might be huge (and I don't have the tablet to test), I might be able to just provide suggestions for your project.
In the Basic section:
Simple UI: It should be easy, due to the fact that many launchers today are user-friendly and easy to use.
Simple to use apps that perform complex stuff: do give some examples.
accessibility capabilities: I don't know of much apps for that (there could be some in the play store) but once we attract the attention of some developers, we can start rolling.
Monitor the device remotely: what do u mean exactly?
Isn't monitor the user's interaction same as the point above? Correct me if I'm wrong.
More suggestions:
Create some tutorials for some complicated apps.
Better colour profile.
Less bright screen=less strain to the eye in low light conditions.
Bigger font=less strain to the eye.
More suggestions will come as I think of them.
Smack that thanks button if I helped!

Good advice, but I feel too many launchers have too many options. the main thing the user needs is simple to access apps. Maybe large icons, etc.My mum likes her news and weather too so simple widgets may help with things like that (A lot are provided with the apps).
TTS will be required too (Text to speech). Maybe an app that will speak highlighted words? Probably have to be built?

By the way, By 'Monitor the device remotly' I mean basically the same thing I have with my kids tabs. Screen Time (MASSIVE RESPECT TO THIS APP!!!) It monitors what my kids do on their tab and allows me to lock it at certain times and give them chores to earn rewards. NOT the same thing we need here, but, thats the kind of monitoring im thinking. Monitoring medication (pop up reminder and if its not used a remote notification)
Any more ideas you have then let me know, Many thanks for your input

I can help test launchers according to what u want and report back. Widgets are easy. (Most news apps has widgets.) There may be some apps for TTS designed for this but it's rare (if not none). (TTS apps are extremely complicated) yea, we might need to build it. (Build from Google voice search, possibility)
OK... I'll have to search it up on Google. (We may have to build from another app...) we can build from Screen Time (add some features into it, we could ask Screen Time's developer for help!)
P.S. I think editing a system file can increase the maximum volume of the sound...

Hi.
I am Leo. I am a visual UX designer within a product team. I have an honest question, that I could not find being discussed anywhere on the web.
I am aware of the multiple asset formats that are required for Android development (hdpi, xhdpi, xxhdpi, and so on). Since I read that most new startups find it easier to develop apps for the mobile devices first in iOS format instead of Android, my question is this:
Is anyone to your knowledge working on an Android solution to this need for multiple image formats? I know this is required because so many different devices and screens are supported. But i have always wondered why no one is working on something in the code that would take the most high density image and 'res' it down via the code, to work on all devices. Therefore allowing a visual UX designer like myself, the ability to design at the highest resolution and provide only one image asset to my development team.
For iOs devices to sets of image assets are supplied to engineering. standard size and the @2x size. I believe Android adoption and apps would increase if the production time for these image assets could be minimized by business.
Thank you for any info, that helps me understand if this is not doable or any links to articles where people are discussing this very issue.
Sincerely,
Leo
Hi Guys
I've been developing a http based Server Software that uses an android device as a single purpose device.. say an input terminal. So I developed a very simple app just for this input purpose (including some data from sensors on the device). It aslo loads a web view for a little html banner.
So it's really simple and the design is to basically turn an android device into a single purpose hardware... and with that said i really dont need 90% of what's installed and running on android, I dont need complicated launchers, and i DO need to kind of "lock the device down" to my app only (i guess kiosk like?)
I basically need the hardware and the OS to run my app.
if possible make everything as lightweight as possible (again as i dont need most of the android features)
and I would love it if my app can run on top of everything and at every start up (it can even pretend to be the SHELL or OS on top of Android OS, or kind of like that approach)..
So yeh, I'm hoping you guys can give me some advise/suggestions as to how best to approach this? (honestly i'm fairly new to android as a whole)
Things off the top of my head are:
1) Custom ROM like really plain/lightweight w/ lock down features <-- is there even any rom like this? or could i ask someone to code this for me?
2) Root, SuperSU, and xPosed Framework plugins and tweaks ? <-- i've not tried xPosed Framework and Im not sure if it's meant to be, or good for, my purpose.
3) Use an APP that can pretty much make a Kiosk out of the phone, w/ my app running permanently? <-- i've seen one kiosk app www.kioware.com but it's crazy expensive and i guess a bit of an overkill to what i need.. Perhaps there's a cheaper more simple kiosk app you can recommend? or perhaps an opensource project i can tinker with?
Would really appreciate your thoughts on this..
Thank you very much!
A common request
Can anyone direct me to a thread where this issue is resolved? It seems more complicated than it seems at first glance.
