Develop Bugs

Interested in Developing in free time

I just recently decided that I have had enough of WinMo on my tilt2 and opted to see how the development of Android OS was coming along for the phone. Not surprisingly, it has developed a lot since I first picked up the phone in December and first thought of the idea of placing Android on the phone.
To my point-- I have some programming experience and would be interested in learning the language behind Android. Obviously it is linux based, but is that the only thing I need to know?
Does anyone know what I need to know to get started?
Links to appropriate sites with details on the language is really what I am looking for. Thanks to any and all that will help (not looking for trolls, get enough of those from other sites).

I too am learning linux, I've had to use linux commands for over a year now as I also own a G1 and you often (when rooting) need to go into a terminal to make changes. I unfortunately don't know much of the language required to create or change much of the android OS I only know the file structure and how to change that. If I were you I would jump over to http://www.android.com download the developers kit which comes with an android emulator and they have lots of tutorials and demo apps for the android OS. It won't do much as far as help you modify the system but it's a good place to get started.
Hope this helps and if you have any questions about the things I do know, feel free to ask me

[Q] Booking system app for Windows Mobile

Hey guys
I'm an entrepreneur from Brisbane, Australia. I'm looking into introducing a new product and am wondering if you guys would be able to help me clarify a few questions. I have to add I have no idea what so ever about programming languages or whats possible or not. I just going to post my vision of the application I will need and hope some of you guys can tell me what of that will be possible, what not and how much effort / money it would take to realise.
Firstly of all and most importantly I need the the Phone application to work with several other systems which would be at the moment : - Iphone, Facebook, Windows Mobile, Blackberry Android, a Website interface, Windows Vista / 7 and Mac OS. I need this to work in two ways. One for the user to sync their data on different apps and secondly for the admin to receive and send data from the main system (that would be working on Windows or Mac)
On first interface the user would have to log in with a username and password, high security would be welcome, after the log in the general interface should be offering the user a booking request form with the ability to use a saved lists of items which have been previously use / prepared but also a interface for add one or editing
It also should offer a open bookings lists and the ability to edit this lists. This should also be able to be synced to the other systems. A third interface showing a history and updates should be also available.
If possible it should offer different accounts and groups where admins can edit the bookings of other users. If this is possible it also should offer a control for the admins which shows bookings and history of other group users.
I would like this obviously to be a professional looking app which offers a good service and is secure and bug free. If anyone has an idea if this is realisable or what parts of it would be difficult or have to be changed please do me the favour and comment.
Thank you for your help in advance.

GUI For Managing Jelly Beans Multi Account Feature

You may have heard talk of the experimental and unannounced multi-account feature in Android 4.1 that allows you to create multiple profiles on a device. In a nutshell it allows you to use your mobile device in a manner similar to how you are able to use a PC, where separate user profiles can be created. This makes it perfect for a household where multiple people may use a tablet on a daily basis, or simply creating a profile which allows others to use your phone without accessing certain apps like social networks and messaging
This semi-hidden feature is enabled via the terminal emulator application, once a new account is created, it becomes available via the devices power menu. It’s pretty simple stuff. However XDA Forum Member Raghav Sood has taken it upon himself to make this feature more user friendly by creating a GUI that allows you to manage these accounts without the use of the terminal. It performs simple operations such as creating, renaming, and deleting users; viewing all current profiles; and of course, switching between them. The developer also explains what the relevant terminal commands are if you prefer to do things the long way.
It’s important to remember that this new function is far from finished, and there wills be bugs. However, it does look quite promising. If you would like to try this out for yourself then check out the original thread.

No need to make a thread here as its covered in android development forums.

LOS 17.1: rights management for multiple users

I am trying to register Signal for a second user on my LineageOS 17.1 on a Fairphone 3+. It fails, looping me through the process and the Google ReCaptcha. Apparently the registration needs an open port 443 and UDP traffic rights.
Unlike my first user where I sucessfully registered Signal just two days ago, the second user (mainly to be used with the second, professional SIM) appears to lack the corresponding rights. I activated multiple users in Settings --> System --> Advanced --> Multiple users. Yet only the first user is set to have admin rights. This seems to be hard-coded...
At least I couldn't find any way to influence the user rights so far. Though this thread indicates meddling with /system/build.prop could be a solution, I would rather find a solution without rooting the device.
Do you have any ideas?
Essentially, I would love some frontend for an aggregated UserManager. If there is none, could you give some hints as to how to change the variables mentioned in the link when rooted?
--
On a sidenote, the Multiple Users feature traded some of its functionality from Android 9 to Android 10 imho... while before you could grant access to specific apps on the main account, now it's really separated users with separate app installs and such. This is great for some use cases including mine, though in order to be more useful, some more options would be nice (restrictions (think about kids usage), rights management, define locations for shared data, ...).
PS: if this is the wrong forum for such a question, please point me to the right one.

Sounds like a question for stack overflow or signal support.

Question Multiple users on Fold 3? (aka work profile)

hey everyone,
I am struggling to find the option for adding another user.
I found this and this article on samsung web however netiher works for me.
The goal would be a completely secondary user for my work (work profile) which is password protected.
do you guysknow how to enable it?
Thanks!

As your account is linked to a Samsung account.
Best gues is go to settings and tap on you name and see there

I believe multiple users requires a rooted phone if your carrier does not enable it for you. I have not done this on the Fold 3 since I want the camera to continue to work and rooting it will kill the camera - thanks Samsung!
This is how you change BuildProp to enable multi user if you have root: How to Add Multi User Support to any Android Device with a Build.Prop Mod
Once you have it enabled, here is how you add users:

Not sure about a completely different user, but does the Secure Folder work for you? Separate apps, contact lists, can't paste outside of it, separate files, etc. all password/fingerprint protected.

I meant Secure Folder, and fixed it, but I'm glad you knew what I meant!

I used secure folder for my work purpose as well, all the company login, apps are completely separate via secure folders and the company admin won't be able to see my non-work information in this manner.

Have you looked at - Island App or the Play Store link?
Sounds like it does what you are looking for.

This looks like it's the same as Secure Folder, but will work with non-Samsung phones.

Correct, it is a non-Knox solution.
