Help with writing Xposed module to bypass audio recording limits. - Android Q&A, Help & Troubleshooting

Hello all,
I am interested in writing an Xposed module to enable all Android audio recording apps to have the ability to record all types of audio regardless of if a given app tries to block it, and including phone calls. Is this the appropriate way to handle the goal here? I believe I have tracked down the function calls in the Android API that need to be spoofed to achieve this, but I am still struggling. If I share what I have so far, would it be appropriate to ask here? I am not even sure if Xposed is the right way to go about this. Perhaps it should be done using Zygisk?
Thank you.

Hello.
I would like this!
Why just audio? What about video too?
What automated recording? I like it for VoIP and videoconferencing.

I apologize for the error. Even though I have been an XDA member for a while, I'm not one of the most active members, and therefore sometimes still struggle with navigating to the proper forum when asking questions. Thank you for pointing this out and correcting it.

Well, for video, there's really nothing that needs done that isn't already available in other Xposed modules. The only reason video recording would be blocked by an app is if it sets FLAG_SECURE, and there are already several Xposed modules that override it. Here is the one that I use on my phone: https://github.com/VarunS2002/Xposed-Disable-FLAG_SECURE
As for automated recording for VoIP and videoconferencing, that is outside the scope of what I would like to achieve with this module. Ideally, what I want this module to do nothing more than allows audio recording apps to access audio streams that they would not normally have access to. I am not sure if this is feasible though. Currently, all apps that have the ability to intercept audio streams that are not accessible through the Android API are closed source. The community needs an open source solution, and I would like to provide that, but I need help.

So, does anyone have an interest in this? Unfortunately I am kind of at a dead end until this is sorted out.

I'm very interested in this, but I'm not a developer unfortunately.

Thanks for your interest! If you know of anyone that is experienced with Xposed module development and would be willing to help me out, please pass this along to them.

Hello all! Is there still nobody with an interest in doing this?

I'm interested in this project as well, for change of that outdated VoIP recorder, but don't have any knowledge about it unfortunately, we have to somehow make more people know about this thread

Is there any way to make this thread alive and bring some developers? With new android versions upcoming and new devices, we won't be able to use boldbeast voip recorder anymore, and there's literally not a single alternative app to it, even cube acr isn't that good, can't record discord, skype, zoom etc..

I'd love to invest time in this again, but unfortunately, my personal life is packed with other things that are limiting my free time to further investigate this at the moment.

Automatic Information Capturing

I am in process of developing an application and I was wondering if there is a way to capture users information automatically. I am drawing up a spec of application functions that I am going to have a dev team produce so I do not have app dev skillsets. That being said...
My idea was that if an user downloads an application, starts it, and the app is automatically populated with the users' phone number, name, etc any basic information automatically. Google pairs the phone with specific accounts that store such information so the data is there. I am looking for a less intrusive way and more user friendly way of creating accounts rather than direct social media login integration.
Is this something that is viable? or is it against data laws? or not possible?
Please let me know if you know of any existing methods, or if you think it is even impossible.
THANKS! :highfive:

How to get rid of Playstore requirement for some apps?

Some of us do not install G**gle apps (incl Play). We use instead F-Droid and APKPure.
But some apps insist that they require Play... it's not a technical requirement, just one they throw in there, but it's a real problem as I am not going to install Play just for that.
Does anyone know of a Play 'placeholder' or 'simulator' which will satisfy this specious requirement? Or has anyone decompiled an app to remove this requirement?
Recommendations?

Apparently you haven't actually tried this. There is very little depth of knowledge about things Android, in general. We are fortunate here to have a competent dev and some competent users. This is rare.
It is unusual to not be at all dependent on G**gle, and I am happy to help with what I know about freeing yourself completely. But there are some catches, and the question I'm asking is the last one for me.
I can probably figure it out for myself, but when forced to do that I am not as inclined to share if sharing (or even trying) is not part of the ethos..
So can we can, or can we can't? :cyclops:

Try MicroG. Your purpose will be solved without installing any GAPPS.

Always share helpful info.
I believe the response the person made was a legit argument basically being made to help direct you to find a better place with much higher odds of getting an answer (looks like you got it tho).
But that doesn't mean you can't ask or can't share. It's all up to you. Sharing knowledge is the foundation this forum has thrived in. Personally I hope nothing defers anyone to question that regardless of any responses made or not made.
And yes, this is an excellent dev. But he's here to help primarily with his area of expertise, which according to the thread title is with Havoc issues. He can't be relied upon to answer non ROM questions (yet he probably would if he knew).
@Quantumstate,
I had to move your question and the corresponding answers to a specific thread (your thread now) to "Android Development and Hacking Android Q&A, Help & Troubleshooting" because the thread where you posted initially was not the best place to ask.
I have named the thread "How to get rid of Playstore requirement for some apps?" because I had to fill a subject (is mandatory) but feel free to edit the title yourself if it's not OK for you.
Also, I suggest you to read THIS THREAD by @Oswald Boelcke, you could eventually find some clues there. If not maybe Oswald Boelcke or any other members (developers or not) here should be able to help you in this new Q&A thread
Thanks for understanding

@Quantumstate I just realised that @Wood Man pinged me and pointed you to my thread. Feel free to ask me in my thread or certainly here whatever you want to know. But I assume you first have a lot of reading ahead.
Additionally to my thread, I'd like to drag your attention to some more XDA threads in this context. In these threads are also links to Github/Gitlab including excellent tutorials. If you want you'll be able to leave Google services or requirements in many although not all cases behind; however, it also depends of the ROM(s) you use. This means if you commence a discussion please also provide insight into details of your device, system and configuration.

Last remark: On none of our devices, any Google service or application is installed. But all of our application run fine without and by the use of µG instead. The very few application, from which I expect push notifications, do receive them on time via GCM/FCM.
The one and only Google application, which I've installed, is the Google Play Store modified by Setalphia, the developer of above linked NanoDroid. It allows me easy access and updates of my applications purchased on Google PS respectively to conduct in-app purchases that I mainly do in order to support a good development and developer unless the developer offers different means of donation.
I knew we could count on you Oswald :highfive:

Hacking Samsung CSC Code To Enable Call Recording

Hi everyone - new member here, so maybe this has been covered, but thought I would ask anyway.
As we all know, the Samsung dialer enables native call recording from only a handful of countries and uses the phone's CSC code to make that determination. Other than rooting the phone - which trips Knox and potentially causes other problems and is super complicated for newbies, the only solution is to change the CSC code to one of those countries via a utility, which seems to work well from the posts here (p.s. third party recording apps cannot reliably capture the other side of the call).
The problem is that in order to even do that, you have to have a European model "B" or "E" phone - meaning, all lhe US based "U" phones are hopelessly without any solution.
My question is, why is it so difficult to hack the dialer into thinking the phone has the necessary CBC code that enables the recording, especially since it would appear to be a very localized and specific call for one piece of data that could be spoofed. I'm sure there's a very good reason why it can't be done, but thinking more along the lines of using a PC or Mac, it would seem simple enough to load some code at startup that would fool the phone into enabling the call recorder option.
Any thoughts?

[Google Wallet] How to change the default bank card picture in the application?

Hey, community!
Is there any chance that someone of you knows the hack of how to change the default picture of the bank card in Google Wallet?
The problem is that I have two identical cards in my bank that are linked to the EUR and USD accounts and I always mess up while picking the wrong one.
My bank doesn't allow me to change the appearance of the card as some fintech banks do, but I remember when I was using iPhone with jailbreak it was possible with some tweaks to upload the custom card picture.
I've tried to check the Android file system but didn't find anything really helpful.
Maybe someone knows the way, thanks!
