Hey xda-forum!
I am currently trying myself on some Android development and need a little bit of a head start - I usually roam around in Web Developement and Scientific Data Analysis.
I want to quickly be able to switch back and forth my System Locale in Android by using a TileService.
I know from extensive googling and reading that since Android 4.2 these system settings are protected by the "WRITE_SETTINGS" permission.
As I only wanna use this "app" on my own, I am not bothered by this as I can grant that.
The question I am asking myself is how to actually set such a permission and what the correct identifier is for setting the locale.
I unfortunatly am too stupid to find it in the Android Documentation and the often refered "MoreLocale" app doesnt help me much as it doesnt work anymore apparently and the used code is deprecated.
Would be amazing if one or multiple of you could give me a heads-up on that, either pointing me into the right direction or giving me an example!
Thanks!

P.S.: I think this belongs more to Software Development but I don't have enough posts to go there ^^ Sorry.

Hi all,
This thread pertains to the inbuilt Internet Calling feature on Gingerbread. By default, it uses g.711 but I use an audio broadcast unit which requires g.722.
Is anyone able to help me, with finding out where the prefs are for the default SIP client, and how to enable g.722 as Mon codec de preference?
Many thanks
Perhaps I should post this in Dev...
Well, according to the rules, I'm not allowed to post a development based question in the dev forum. Apparently "If it's not about a ROM, it's not allowed in the development area" - perhaps the 'Dev' area should be renamed 'ROMs', and a separate Development Area should be opened?! That way, serious questions won't get overlooked and moved down so quick with the masses of repeated questions from new members.
Anyway - thats my rant...
Here's my actual question - reposted:
Hi folks
OK, this isn't ROM related as such, but it is definitely development related, hence posting here. I'm not a programmer, but I know my way around config files etc. usually. What I'm trying to find out, is this:
Can I adjust the 'built-in' VoIP Client to use a different codec? There's no options available in software, but the config for the client must be somewhere - question is, WHERE would it be? If anyone can point me in the right direction, I'll report my findings
There's a few VoIP things I want to customise, but using the native client, rather than a third party app.
I'm not after a spoon-fed solution - just the clues where to look so I can sort it out.
Many thanks
Just unzip any ROM and look inside,
That would spare you own phone and you can check every single file.
Btw, apk are zip files as well...
I've had a look around, but still haven't found the right things.
I guess the 'Internet Calling' function is part of the main 'phone' app, but I can't find any settings or config files for this.
It should be such a simple change to make; but I'm stuck at the first hurdle!!
First, I know there are some other topics out there asking the same exact thing, but I think my situation is kinda different.
So, want to learn how to develop for Android. Building custom ROMs, Android apps, tweaks, etc. But my actual knowledge is only user lever. I only know what a android user should know (flash ROMs, root, etc). Zero dev knowledge. Nothing.
I want to know with what should I start to learn to do Android dev. Nothing like: 1 hour and you're the best dev out there. I know it takes time. But I want to focus on Android.
So, what do you have to say?
In very general terms it would be to pick one of your favorite roms for your phone, pull it apart and then put it back together until you understand what is going on.
In more "specific" (though this is frankly scratching the surface) terms, you would first spend hours finding out how to back up your phone including the AAA key, the meid and so forth as well as other software compatible with your phone to restore it. As frankly since you're likely using your phone to test, you'll have more than one occasion it will be soft bricked.
Thereafter you would learn more in regards to development tools, in specific over at developer.android.com. Read the dev guide and so on.
Third, decide how you want to implement a unix/linux test environment, unless you're already on linux.
And forth you'd look at your favorite rom developer's build from their development site (the name of the domain escapes me) pull it apart and try to analyze the details.
Last but not least you'd FOLLOW new developments with android and the phone as well as learn to adjust to any new firmware that comes out from the manufacturer.
I'm in the process of learning how to develop myself but I've already discovered a lot more with the phone's underlying structure. That said, a lot of the answers are found in bits and pieces on this forum. But when you start to learn and ask specific questions like "what partition is the system mounted on for a Samsung Galaxy Ace" you'll begin to understand the file structure and then underlying software involved.
This was very helpful. I'm glad to see there are helpful people here that aren't going to talk down to a "new user" and I was also wondering how I could view files on windows 7. For example the structure of apk files or any of the others that say no program found to open this file
For example I want to begin by changing the boot screen from the solar flare looking Android boot screen to scrolling tiles or something of the sort then back can some explain that and I'm sure I can gain quite an understanding on the process that way

If you want to do programming you should start with the Android SDK: http://developer.android.com/sdk/index.html
An apk file is actually a zip file.
If you want to get an idea of all the stuff that is in there, just rename it to .zip and open with your favorite utility.
The contents of this archive file are also in binary form and compressed.
To get down to the lowest level you need to use something like apktool: http://code.google.com/p/android-apktool/
Much obliged I'll do that. Any Intel on boot.img

hi all!
please note: i am nothing near a professional user or even coder! i rooted my phone and i install custom roms on it, and thats about it. in addition to that i am concerned about my privacy. for me it started with the LBE Privacy Guard from the play store, it was quite nice until it stopped working, and made my phone stuck in a boot loop...
i have read and searched a lot of stuff before i decided to write this. but i havent found an easy and understandable how to. maybe that is because there no easy way to this. please go easy on me if there is already a thread for this...
i just installed openpdroid on my samsung galaxy s+ (i9001) and that is just because user bululu has made a patch for the rom i am using (cm10.1 from user davidteri) - thanks to both of them! i installed the patch with cwm (clockworkmod) and afterwards i was wondering there is no privacy setting in my menu or anything that would let me set up permissions. but from all the stuff i was reading before i figured i will need some kind of gui (not sure this is the right word - that goes for most of the stuff, but please correct me where u can, i will try and learn) so i installed 'pdroid manager' from the play store. that would finally let me set permissions for the apps! so far, so good. i am now using openpdroid...
should be all good at this point u might think, but this is where my questions begin ^^ f.ex:
is this the best solution atm? are there more solutions? what are the differences? what can u recommend?
furthermore i try to figure out how to encrypt email on android. most things i read point to k9 mail and using agp (or apg? is this the same?). i did some research on that topic an it seems to be the 'android privacy guard'. more questions here too...
it seems to be out of development, since the last changes are from 25.12.2010. is there a newer alternative for that or something i missed? or maybe it is still the thing to use or it is quite finished in its current state?!? but i dont wanna clog my device with old or unsupported software until i am 99% sure on what to do...
so basically i am asking if there is a nice and user friendly (with images) 'how to' for this kind of stuff i was just missing or is it just impossible (at the current state) to do such thing? if both answers are 'no' i'd like to start something like that, of course with your help that is...
because it seems the info i found is not coherent, its all bits and pieces one needs to bring together (in the right order and with compatible software). at least thats what it feels like for me as non-professional user and linux noob. i have no problem with puzzling stuff together but i also would like to help others who would like to do increase their security and get different opinions on whats the best way to do some things...
so if any of u got an opinion to any of the above please let me know! and help or links would be greatly appreciated! lets see if we can bring some things together and make our devices, our communication and our data more secure! and please note: this should not be device specific, my device and rom was just for information and for better understanding my starting point. this should be as broadly defined and open minded as possible. so everybody could partake and make use of it...
thanks for reading!
kind regards

So I am going to post this here, because the development section is ferboten to people trying to offer useful suggestions. Geez, I hope this is the right section.
Let me set it up. ANDROID IS BASED ON THE LINUX KERNEL. Everything, and I mean everything after that fact becomes android and bloat. Given this as the basis of all things android, I have a simple set of guidelines that should be used to create a solid, reliable, bullet proof operating system for devices able to use the android operating system.
#1. Create the kernel boot section of the basic platform that supports the very basic hardware features, including touch screen, radios, power/charging/battery management, wifi, bluetooth, nearfield, audio, microphone, s-pen,etc. Basics only. Root access is standard and can be turnd on/off just like developwer functions. No special tricks or addon hoops to jump through.
#2 At this point STOP. Every single process or service to be run on the device from this point forward should be able to be individually selectable - or not. Yes, I understand that individual services or apps may have dependancies to other processes and that thouse need to be functional in order for a particular app to work. That is why, each additional service or app must list the dependencies and in the selection process, the installion will be required to verify you have the proper services installed and functioning, if not to list them and allow you to make the decision to proceed. Viola, we have NO MORE BLOAT WARE.
#3 Make selecting additional services/apps selection process a menu driven, tag selectable process. Make the unselection process smart to verify and identify the other apps dependant on the item you are killing/removing.
#4 Allow a built in snapshot option to capture the entire system as you have customized it for yourself and allow it to be backed up to external memory with the ability to bring it back, AT WILL. With no big hassles.
Those 4 items are a good start. By themselves alone, it would put all of us in the drivers seat of controlling and living with our devices.
I am aware that such a system is not for everyone. It does require some basic technical understanding of the process. But for the vast majority of users, I am certain, that an a la carte system is far superior to the bloated monstrosities being forced down our devices.
I would appreciate any refinements to my suggestions.
The silence is deafening. It has been days. Kind of says something, don't you think?
I am so very happy (not) that these boards a compartmentalized to the point where you can't get through.
Pretty much a waste of my valuable time, especially considering the fact that if my suggestions where applied, people would be clamoring for an installation with those features. I guess there is not much true "developer" in xdadevelopers anymore.
Funny guys, with the pay to remove ads spam here. Really? Why? For what.
I leave here disappointed. Not angry. Just sad.
I'm not a developer so I have nothing valuable to contribute to your suggestions in your original post but I can offer an observation regarding your perception of the level of contribution to your thread and that is the fact that is particular area of the forums probably isn't the ideal spot to have a discussion such as this. You figured that out already so sure you can call me Capt. Obvious if you wish but I'm just pointing out that yes the forums are compartmentalized (as you've stated) in such a way that development for each device is separated out. This development is centered around AOSP based ROMs or "stock" ROMs (using manufacturer released source) so if you're looking to have higher level discussions about what AOSP should look like then deep down at this device specific level probably isn't where you want to be. So there's that . . . then there's the fact that for this particular device you can basically hear a pin drop in the sub-forums as it is since nothing much is going on by way of development.
Where specifically such a discussion would see more input I'm not sure, perhaps the main general discussion section?
Thank you for your sobering reply. I get frustrated. Already had my post bounced out of "wrong" forum while trying to speak directly to "developers" (i wanted air quotes because the term does not accuratly describe its target) So I tried this. The note pro 12.0 is still the best hardware giving the ipad a run for its money. The problem its monkeyshines kiddie software running it, or not running, or barely running it. ANDROID, indian word for crappy wannabe software, developed by clueless kids.
Again, thanks for the gentle nudge. I appreciate someone willing to conduct a conversation
Are you looking for an Ubuntu or SUSE type of setup?
I think what you are looking for is similar to apt-get type of installs, I could be wrong of course. This might be helpful for many "users". I think one of the barriers is that there are slight differences between the models of tablets, and creating the logic to put in for the sub-dependencies might prove problematic. You might get more answers to this possibility by asking one of the developers directly and sharing with them. Not a developer myself.
Hello,
I hope I am right here - I could not post in the dev forum because I am not long enough a member here.
Please forgive me this potential noob question, I know how these questions suck for advanced forum members but I simply don't find another way to solve my problem. I googled like crazy and tried to understand the material I found - without success.
I am new to coding and decided to code a simple app which displays a website, just for myself.
Because WebView does not support all the JavaScript Functions the websites needs, I decided to go with GeckoView - which worked fine.
I was really happy to get the app running, even though it's super basic
The website loading inside GeckoView now needs permission to access the microphone of my device.
So I added to AndroidManifest.xml the following line:
Code:
<uses-permission android:name="android.permission.RECORD_AUDIO" />
... still did not work.
When I open the website in question in regular Firefox, the browser asks me to grant permission.
So I guess I need to give GeckoView itself permissions to access the mic.
I looked into the documentation but could not understand anything (I wanted to include the like to the doc here, but because I am new, I can't link to external pages. If you google "Interface GeckoSession.PermissionDelegate" you will find the documentation I am talking about). I did some try and error experiments but it was not working. It was more or less wild guesses because I even could not find any example code/projects using these permissions so I could try to understand it better.
I am simply stuck. I read everything regarding these permissions but have a hard time understanding most of it.
That's why I came here. I would highly appreciate your help so I can finish this seemingly easy task.
Thanks a lot!
