+
+        Without logs most bugs are very hard to diagnose. If you are not, follow these instructions:
+        (Needs access to a computer, and USB/Wireless Debugging under developer options enabled)
+
+        Commands:
+        - Get the uid: Linux/Mac: `adb shell dumpsys package me.kavishdevar.librepods | grep uid`
+        - Start logs: `adb logcat --uid=<uid>,1002 >> librepods-logs.txt` (1002 is for bluetooth)
+        
+        Steps for proper logs
+        - force close the app
+        - turn off bluetooth
+        - start logs
+        - open the app
+        - turn on bluetooth and connect

-# Contributor Covenant Code of Conduct
-
-## Our Pledge
-
-We as members, contributors, and leaders pledge to make participation in our
-community a harassment-free experience for everyone, regardless of age, body
-size, visible or invisible disability, ethnicity, sex characteristics, gender
-identity and expression, level of experience, education, socio-economic status,
-nationality, personal appearance, race, religion, or sexual identity
-and orientation.
-
-We pledge to act and interact in ways that contribute to an open, welcoming,
-diverse, inclusive, and healthy community.
-
-## Our Standards
-
-Examples of behavior that contributes to a positive environment for our
-community include:
-
-* Demonstrating empathy and kindness toward other people
-* Being respectful of differing opinions, viewpoints, and experiences
-* Giving and gracefully accepting constructive feedback
-* Accepting responsibility and apologizing to those affected by our mistakes,
-  and learning from the experience
-* Focusing on what is best not just for us as individuals, but for the
-  overall community
-
-Examples of unacceptable behavior include:
-
-* The use of sexualized language or imagery, and sexual attention or
-  advances of any kind
-* Trolling, insulting or derogatory comments, and personal or political attacks
-* Public or private harassment
-* Publishing others' private information, such as a physical or email
-  address, without their explicit permission
-* Other conduct which could reasonably be considered inappropriate in a
-  professional setting
-
-## Enforcement Responsibilities
-
-Community leaders are responsible for clarifying and enforcing our standards of
-acceptable behavior and will take appropriate and fair corrective action in
-response to any behavior that they deem inappropriate, threatening, offensive,
-or harmful.
-
-Community leaders have the right and responsibility to remove, edit, or reject
-comments, commits, code, wiki edits, issues, and other contributions that are
-not aligned to this Code of Conduct, and will communicate reasons for moderation
-decisions when appropriate.
-
-## Scope
-
-This Code of Conduct applies within all community spaces, and also applies when
-an individual is officially representing the community in public spaces.
-Examples of representing our community include using an official e-mail address,
-posting via an official social media account, or acting as an appointed
-representative at an online or offline event.
-
-## Enforcement
-
-Instances of abusive, harassing, or otherwise unacceptable behavior may be
-reported to the community leaders responsible for enforcement at
-report@kavishdevar.me.
-All complaints will be reviewed and investigated promptly and fairly.
-
-All community leaders are obligated to respect the privacy and security of the
-reporter of any incident.
-
-## Enforcement Guidelines
-
-Community leaders will follow these Community Impact Guidelines in determining
-the consequences for any action they deem in violation of this Code of Conduct:
-
-### 1. Correction
-
-**Community Impact**: Use of inappropriate language or other behavior deemed
-unprofessional or unwelcome in the community.
-
-**Consequence**: A private, written warning from community leaders, providing
-clarity around the nature of the violation and an explanation of why the
-behavior was inappropriate. A public apology may be requested.
-
-### 2. Warning
-
-**Community Impact**: A violation through a single incident or series
-of actions.
-
-**Consequence**: A warning with consequences for continued behavior. No
-interaction with the people involved, including unsolicited interaction with
-those enforcing the Code of Conduct, for a specified period of time. This
-includes avoiding interactions in community spaces as well as external channels
-like social media. Violating these terms may lead to a temporary or
-permanent ban.
-
-### 3. Temporary Ban
-
-**Community Impact**: A serious violation of community standards, including
-sustained inappropriate behavior.
-
-**Consequence**: A temporary ban from any sort of interaction or public
-communication with the community for a specified period of time. No public or
-private interaction with the people involved, including unsolicited interaction
-with those enforcing the Code of Conduct, is allowed during this period.
-Violating these terms may lead to a permanent ban.
-
-### 4. Permanent Ban
-
-**Community Impact**: Demonstrating a pattern of violation of community
-standards, including sustained inappropriate behavior,  harassment of an
-individual, or aggression toward or disparagement of classes of individuals.
-
-**Consequence**: A permanent ban from any sort of public interaction within
-the community.

-# Bluetooth Low Energy (BLE) - Apple Proximity Pairing Message
-
-This document describes how the AirPods BLE "Proximity Pairing Message" is parsed and interpreted in the application. This message is broadcast by Apple devices (such as AirPods) and contains key information about the device's state, battery, and other properties.
-
-## Overview
-
-When scanning for BLE devices, the application looks for manufacturer data with Apple's ID (`0x004C`). If the data starts with `0x07`, it is identified as a Proximity Pairing Message. The message contains various fields, each representing a specific property of the AirPods.
-
-## Proximity Pairing Message Structure
-
-| Byte Index | Field Name              | Description                                             | Example Value(s)         |
-|------------|-------------------------|---------------------------------------------------------|--------------------------|
-| 0          | Prefix                  | Message type (should be `0x07` for proximity pairing)   | `0x07`                   |
-| 1          | Length                  | Length of the message                                   | `0x12`                   |
-| 2          | Pairing Mode            | `0x01` = Paired, `0x00` = Pairing mode                 | `0x01`, `0x00`           |
-| 3-4        | Device Model            | Big-endian: [3]=high, [4]=low                          | `0x0E20` (AirPods Pro)   |

-
-### Status Byte (Bitfield)
-
-| Bit | Meaning                        | Value if Set |
-|-----|--------------------------------|-------------|
-| 0   | Right Pod In Ear (XOR logic)   | true        |
-| 1   | Right Pod In Ear (XOR logic)   | true        |
-| 2   | Both Pods In Case              | true        |
-| 3   | Left Pod In Ear (XOR logic)    | true        |
-| 4   | One Pod In Case                | true        |
-| 5   | Primary Pod (1=Left, 0=Right)  | true/false  |
-| 6   | This Pod In Case               | true        |
-
-### Ear Detection Logic
-
-The in-ear detection uses XOR logic based on:
-- Whether the right pod is primary (`areValuesFlipped`)
-- Whether this pod is in the case (`isThisPodInTheCase`)
-
-```cpp
-bool xorFactor = areValuesFlipped ^ deviceInfo.isThisPodInTheCase;
-deviceInfo.isLeftPodInEar = xorFactor ? (status & 0x08) != 0 : (status & 0x02) != 0;  // Bit 3 or 1
-deviceInfo.isRightPodInEar = xorFactor ? (status & 0x02) != 0 : (status & 0x08) != 0; // Bit 1 or 3
-```
-
-### Primary Pod
-
-Determined by bit 5 of the status byte:
-- `1` = Left pod is primary
-- `0` = Right pod is primary
-
-This affects:
-1. Battery level interpretation (which nibble corresponds to which pod)
-2. Microphone assignment
-3. Ear detection logic
-
-### Microphone Status
-
-The active microphone is determined by:
-```cpp
-deviceInfo.isLeftPodMicrophone = primaryLeft ^ deviceInfo.isThisPodInTheCase;
-deviceInfo.isRightPodMicrophone = !primaryLeft ^ deviceInfo.isThisPodInTheCase;
-```
-
-### Pods Battery Byte
-
-- Upper nibble: one pod battery (depends on primary)
-- Lower nibble: other pod battery
-
-| Value | Meaning         |
-|-------|----------------|
-| 0x0-0x9 | 0-90% (x10)  |
-| 0xA-0xE | 100%         |
-| 0xF     | Not available|
-
-### Flags & Case Battery Byte
-
-- Upper nibble: case battery (same encoding as pods)
-- Lower nibble: flags
-
-#### Flags (Lower Nibble)
-
-| Bit | Meaning                  |
-|-----|--------------------------|
-| 0   | Right Pod Charging (XOR) |
-| 1   | Left Pod Charging (XOR)  |
-| 2   | Case Charging            |
-
-### Lid Indicator
-
-| Bits | Meaning                |

+## Find My
 
-#### A few notes
+The following features related to Find My are planned, but require further RE and might need root on Android:
 
-- Due to recent AirPods' firmware upgrades, you must enable `Off listening mode` to switch to `Off`. This is because in this mode, louds sounds are not reduced!
+- Add your AirPods to the Find My network
+- Play sound through charging case to find it
+- Notify when leaving behind
+- Toggle case charging sounds
 
-- If you have take both AirPods out, the app will automatically switch to the phone speaker. But, Android might keep on trying to connect to the AirPods because the phone is still connected to them, just the A2DP profile is not connected. The app tries to disconnect the A2DP profile as soon as it detects that Android has connected again if they're not in the ear.
+## Spatial Audio
 
-- When renaming your AirPods through the app, you'll need to re-pair them with your phone for the name change to take effect. This is a limitation of how Bluetooth device naming works on Android.
+The app does not currently provide head tracking information to Android for the OS to perform HRTF. This has not been explored completely, and it might need root. 
 
-## Development Resources
+Spatializing stereo sound is beyond this project's scope and will never be available. Many OEMs have an implementation of their own for this.
 
-For developers interested in the protocol details, check out the [AAP Definitions](/AAP%20Definitions.md) documentation.
+## Heart Rate Monitoring (AirPods Pro 3 and later)
+This is being worked upon, check the #⁠reverse-engineering channel on the LibrePods Discord server for more information. If it is ever implemented, it will most likely need root on Android.
 
-## CrossDevice Stuff
+## High quality two-way audio
+On iOS/iPadOS, you can continue using A2DP while AirPods send the audio stream from its microphone over AACP. 
 
-> [!IMPORTANT]
+Since this needs deeper integration with audio on Android, it will most likely need root.
-> This feature is still in early development and might not work as expected. No support is provided for this feature yet.
 
-### Features in Development
+# Installation
 
-- **Battery Status Sync**: Get battery status on any device when you connect your AirPods to one of them
+- [**Android**](/android/README.md)
-- **Cross-device Controls**: Control your AirPods from either device when connected to one
+- [**Linux**](/linux/README.md)
-- **Automatic Device Switching**: Seamlessly switch between Linux and Android devices based on active audio sources
 
-Check out the demo below:
+# VendorID Spoofing
 
-https://github.com/user-attachments/assets/d08f8a51-cd52-458b-8e55-9b44f4d5f3ab
+Turns out, if you change the VendorID in DID Profile to that of Apple, you get access to several special features!
 
-## Star History
+You can do this on Linux by editing the DeviceID in `/etc/bluetooth/main.conf`. Add this line to the config file `DeviceID = bluetooth:004C:0000:0000`. For android you can enable the `act as Apple device` setting in the app's settings (shown only when Xposed is available and LibrePods module is enabled).
 
-[![Star History Chart](https://api.star-history.com/svg?repos=kavishdevar/librepods&type=Date)](https://star-history.com/#kavishdevar/librepods&Date)
+## Multi-device Connectivity
+
+Upto two devices can be simultaneously connected to AirPods, for audio and control both. Seamless connection switching. The same notification shows up on Apple device when Android takes over the AirPods as if it were an Apple device ("Move to iPhone"). Android also shows a popup when the other device takes over.
+
+## Accessibility Settings and Hearing Aid
+
+Accessibility settings like customizing transparency mode (amplification, balance, tone, conversation boost, and ambient noise reduction), and loud sound reduction can be configured.
+
+All hearing aid customizations can be done from Android (linux soon), including setting the audiogram result. The app doesn't provide a way to take a hearing test because it requires much more precision. It is much better to use an already available audiogram result. 
+
+# Protocol and Reverse Engineering
+
+Please refer to the Wireshark dissector plugin by Nojus ([@pabloaul](https://github.com/pabloaul)) for more information on the protocols used: [pabloaul/apple-wireshark](https://github.com/pabloaul/apple-wireshark)
+
+The dissector had not been used in LibrePods for most of the implementation; I had reverse engineered the protocol myself before this dissector was made. But many (future) features including two-way high quality audio and spatial audio would not have been possible without their RE efforts!
+
+# Use of AI
+
+## Android app
+
+These parts of the app were completely AI-generated: 
+- Head Gestures - all of it, including logic and the UI
+- The offset setup with r2+the xposed module (both versions)
+- Troubleshooter and LogCollector
+
+Rest everything- the background service, the Bluetooth manager classes (AACP and ATT), the entire UI, even the smallest components were written manually.
+
+Some parts of the UI components were borrowed from [Kyant0's demo app](https://github.com/Kyant0/AndroidLiquidGlass/tree/master/catalog), which is licensed under [Apache License 2.0](https://www.apache.org/licenses/LICENSE-2.0).
+
+## Linux (rewrite)
+
+The `aacp.rs` and the `att.rs` files were translated from Kotlin to Rust with AI. Some parts of the `media_controller.rs` file, mainly the pulse integration, was also AI-generated.

+## Root Requirement
+
+LibrePods *may* require root depending on your device/OS and what features you want access to:
+
+- Features requiring the VendorID hook ([the features marked with an asterisk here](https://github.com/kavishdevar/librepods#key-features)) will always require root regardless of your device/OS.
+- On **ColorOS/OxygenOS 16 and realme UI 7.0** and **Pixel devices on Android 16 QPR3** (with the latest Google Play system update), LibrePods does not need root for most features.
+- On other devices, LibrePods needs root because of a bug in the Android Bluetooth stack Fluoride/non-compliance of Apple with Bluetooth standards. You must have Xposed installed for the app to workaround this bug and connect to AirPods. [This issue is being tracked here](https://issuetracker.google.com/issues/371713238). **Please do not comment on the issue thread.** The issue has already been resolved and should be available in **Android 17** for all devices.
+
+> [!IMPORTANT]
+> This workaround with Xposed is not guaranteed to work on all devices.
+
+
+## Installation
+
+### Google Play Store
+
+If you are using a supported device/OS combination, you can install LibrePods from the Google Play Store. You can use the VendorID hook features with root even from the Play Store version.
+
+<a href="https://play.google.com/store/apps/details?id=me.kavishdevar.librepods"><img width="170" alt="GetItOnGooglePlay_Badge_Web_color_English" src="https://github.com/user-attachments/assets/2948308f-af92-443f-94d9-ee381c3a6ccc"/></a>
+
+### GitHub Releases
+
+If you need xposed because of the [root requirement](#root-requirement), you will have to use the apk/zip from the [GitHub releases](https://github.com/kavishdevar/librepods/releases/latest).
+
+### As a system app (root module)
+
+If you want LibrePods to have privileged Bluetooth permissions to 
+- show battery status in the system settings and widgets
+- show AirPods icon in the system settings (xposed is also currently required for this)
+- switch audio to phone speakers when you are not wearing your AirPods
+
+you can install the root module. This is optional and only provides extra features, but it is not required for the app to work.
+
+> [!IMPORTANT]
+> When using the root module, do not install the Play Store version. There might be issues because of the signature mismatch between the Play Store version and the root module.
+
+## Nightly/Development Builds
+
+Want to try the latest features before they're officially released? You can grab nightly builds from the [latest nightly release](https://github.com/kavishdevar/librepods/releases?q=nightly).
+
+> [!WARNING]
+> These builds are automatically generated from the latest code and may contain new features and bug fixes that haven't been included in a stable release yet. However, please note that they may also be less stable than official releases, so use them at your own risk.

+here's a very unprofessional demo video
+
+https://github.com/user-attachments/assets/43911243-0576-4093-8c55-89c1db5ea533
+
+### Troubleshooting steps for common errors
+- Ensure the correct scope is set in LSPosed/Vector.
+- Ensure there is no root-hiding module preventing the hook from loading on the Bluetooth app.
+- Restart your phone after confirming the scope.
+
+### A few notes
+
+- Due to recent AirPods' firmware upgrades, you must enable `Off listening mode` to switch to `Off`. This is because in this mode, loud sounds are not reduced.
+
+- When renaming your AirPods through the app, you'll need to re-pair them with your phone for the name change to take effect. This is a limitation of how Bluetooth device naming works on Android.

+ * system out of memory when decompressing streams from untrusted sources.

+ * The only possible return values are XZ_OK, XZ_STREAM_END, and

+ * avoid an infinite loop.
+ *
+ * If the compressed data seems to be corrupt, XZ_DATA_ERROR is returned.
+ * This can happen also when incorrect dictionary, uncompressed, or
+ * compressed sizes have been specified.
+ *
+ * With XZ_PREALLOC only: As an extra feature, b->out may be NULL to skip over
+ * uncompressed data. This way the caller doesn't need to provide a temporary
+ * output buffer for the bytes that will be ignored.
+ *
+ * With XZ_SINGLE only: In contrast to xz_dec_run(), the return value XZ_OK
+ * is also possible and thus XZ_SINGLE is actually a limited multi-call mode.
+ * After XZ_OK the bytes decoded so far may be read from the output buffer.
+ * It is possible to continue decoding but the variables b->out and b->out_pos
+ * MUST NOT be changed by the caller. Increasing the value of b->out_size is
+ * allowed to make more output space available; one doesn't need to provide
