Overview

Basic Call Recorder

BCR is a simple Android call recording app for rooted devices or devices running custom firmware. Once enabled, it stays out of the way and automatically records incoming and outgoing calls in the background.

Features

Supports Android 9 through 13
Records FLAC-encoded lossless audio at the device's native sample rate
Supports Android's Storage Access Framework (can record to SD cards, USB devices, cloud storage, etc.)
Quick settings toggle
Material You dynamic theming
No persistent notification unless a recording is in progress
No network access permission
No third party dependencies
Works with call screening on Pixel devices (records the caller, but not the automated system)

Non-features

As the name alludes, BCR intends to be a basic as possible, with only two configuration options: an on/off switch and the output directory. The project will have succeeded at its goal if the only updates it ever needs are for compatibility with new Android versions. Thus, many potentially useful features will never be implemented, such as:

Automatic deletion of old recordings
Changing the filename format
Support for other lossless codecs
Support for lossy audio compression
Support for old Android versions (support is dropped as soon as maintenance becomes cumbersome)
Workarounds for OEM-specific battery optimization and app killing behavior
Workarounds for devices that don't support the VOICE_CALL audio source (eg. using microphone + speakerphone)
Support for direct boot mode (the state before the device is initially unlocked after reboot)
Support for stock, unrooted firmware

Usage

Download the latest version from the releases page. To verify the digital signature, see the verifying digital signatures section.
Install BCR as a system app.

For devices rooted with Magisk, simply flash the zip as a Magisk module from within the Magisk app.

For unrooted custom firmware, the files from the system/ folder in the zip will need to be baked into the system image (or otherwise made available on the actual /system volume).
Reboot and open BCR.
Enable call recording and pick an output directory. If no output directory is selected or if the output directory is no longer accessible, then recordings will be saved to /sdcard/Android/data/com.chiller3.bcr/files.
To install future updates, there are a couple methods:
- If installed via Magisk, the module can be updated right from Magisk Manager's modules tab. Flashing the new version in Magisk manually also works just as well.
- The .apk can also be extracted from the zip and be directly installed. With this method, the old version exists as a system app and the new version exists as a user-installed update to the system app. This method is more convenient if BCR is baked into the Android firmware image.

How it works

BCR relies heavily on system app permissions in order to function properly. This is primarily because of two permissions:

CONTROL_INCALL_EXPERIENCE

This permission allows Android's telephony service to bind to BCR's InCallService without BCR being a wearable companion app, a car UI, or the default dialer. Once bound, the service will receive callbacks for call change events (eg. incoming call in the ringing state). This method is much more reliable than using the READ_PHONE_STATE permission and relying on android.intent.action.PHONE_STATE broadcasts.

This method has a couple additional benefits. Due to the way that the telephony service binds to BCR's InCallService, the service can bring itself in and out of the foreground as needed when a call is in progress and access the audio stream without hitting Android 12+'s background microphone access limitations. It also does not require the service to be manually started from an ACTION_BOOT_COMPLETED broadcast receiver and thus is not affected by that broadcast's delays during initial boot.
CAPTURE_AUDIO_OUTPUT

This permission is used to record from the VOICE_CALL audio stream. This stream, along with some others, like VOICE_DOWNLINK and VOICE_UPLINK, cannot be accessed without this system permission.

With these two permissions, BCR can reliably detect phone calls and record from the call's audio stream. The recording process pulls PCM s16le raw audio at the device's native sample rate and uses MediaCodec's builtin (software) FLAC encoder to create a losslessly compressed recording.

Verifying digital signatures

Both the zip file and the APK contained within are digitally signed.

To verify the signature of the zip file, first retrieve the public key: 2233C479609BDCEC43BE9232F6A3B19090EFF32C. This is the same key used to sign the git tags in this repository.

gpg --recv-key 2233C479609BDCEC43BE9232F6A3B19090EFF32C

Then, verify the signature of the zip file.

gpg --verify BCR-<version>-release.zip.asc BCR-<version>-release.zip

The command output should include both Good signature and the GPG fingerprint listed above.

To verify the signature of the APK, extract it from the zip and then run:

apksigner verify --print-certs system/priv-app/com.chiller3.bcr/app-release.apk

The SHA-256 digest of the APK signing certificate is:

d16f9b375df668c58ef4bb855eae959713d6d02e45f7f2c05ce2c27ae944f4f9

Building from source

BCR can be built like most other Android apps using Android Studio or the gradle command line.

To build the APK:

./gradlew assembleDebug

To build the Magisk module zip (which automatically runs the assembleDebug task if needed):

./gradlew zipDebug

The output file is written to app/build/distributions/debug/. The APK will be signed with the default autogenerated debug key.

To create a release build with a specific signing key, set up the following environment variables:

export RELEASE_KEYSTORE=/path/to/keystore.jks
export RELEASE_KEY_ALIAS=alias_name

read -s RELEASE_KEYSTORE_PASSPHRASE
read -s RELEASE_KEY_PASSPHRASE
export RELEASE_KEYSTORE_PASSPHRASE
export RELEASE_KEY_PASSPHRASE

and then build the release zip:

./gradlew zipRelease

Contributing

Bug fix and translation pull requests are welcome and much appreciated!

If you are interested in implementing a new feature and would like to see it included in BCR, please open an issue to discuss it first. I intend for BCR to be as simple and low-maintenance as possible, so I am not too inclined to add any new features, but I could be convinced otherwise.

Recordings Overlapping

Hi @chenxiaolong

I tried latest v1.4 too but the audio recording overlapping is still there!

Say If I record for a 20 seconds long call then sometimes it's the recorded duration only getting 7 seconds, sometimes it's 11 seconds and sometimes whole 20 seconds!

When the duration reducing say for 7 seconds long recording then the remaining recording of 13 seconds seems getting overlapped between 6th to 7th second of the recorded audio!

I've also allowed BCR to run in the background, So there's no issue with getting it killed in background.

Output format M4A/AAC corrupt (missing moov header?)

Hi,

First of all, I love the simplicity of this app. Keep it that way!

I do noticed that the recorder does record conversations, but the generated m4a/aac files cannot be played correctly. I tried to fix them with e.g. ffmpeg, but it seems the moov header is missing? Not sure tough, as I'm not familiar with the aac format.

See attached files for a few examples. calls.zip

Here's one with debuglogging: with debuglog.zip

I'm using BCR version 1.20 (release + debugmode) Installed /enabled as Magisk module On Android 9, running on Samsuing S8 stock firmware (rooted obviously).

Output dir is default (com.chiller3.bcr/file), format is also default (m4a/aac, 64kbps, 48kHz) App Permissions are Contacts and Microphone

Although I'm not in favor submitting multiple issues at the same time, I also notice that the debug file is often missing, or sometimes has a size of 0 bytes.

Hope you can help, Thanks!

[Question] Custom rom > root > install BCR > unroot

Can it be installed by placing its files in root/system folder using file explorer with root permission, and after installing BCR, can magisk be uninstalled? So that BCR can work like system app, but without magisk.

Basically, this app is perfect; but with magisk, few banking apps are not working properly.

Thanks

Add support for custom date/time format in the output filename

From @nikhilbadyal's comment at: https://github.com/chenxiaolong/BCR/pull/189#issuecomment-1363705779

It's possible to add custom format for ${date} like yyyy-MM-ddHH:mm:ss . I don't want time_zone in output filename. As it container ugly + sign.

Not working after crDroid 9.0 2022-december update

I used BCR in crDroid 9.0 (android 13) without an issue. But after december update BCR stopped working. Notification Also not present. I tried to get the log by enabling release+debugmode but logs are also not saving. All the permissions are allowed. App runs normally. Only the recording is not working. Device - Redmi Note 8 Pro

Possible to enable or disable call recording in the middle of a call?

I see that currently I'm not able to change the state of call recording after answering a phone call. If the call recording was enabled before I got the call, the call will be recorded and I can't stop it during the call. And if the call recording was not enabled before I got the call, I can't enable it during the call.

This leads to situations where I either keep it enabled all the time, and record unnecessary calls too and then delete the recording afterwards. OR not keep it enabled all the time, and risk missing to record a call that I should've, as I can't always make an excuse to the caller to call me again in a minute (giving me a chance to enable recording.)

It would be really really helpful if we can select whether to record a call or not, during the call itself.

(Pixel 7 Pro, Android 13, Magisk Canary.)

[Feature] Uplink and downlink separated source

Hi thanks for the application, it's working very well, I don't know what you think about that but would that be convenient to have at least the caller's source(downlink?), a clean audio without my voice, the wind, the noise coming from my mic overlapping with the caller's audio.

Not working on Android 12, LOS+microG

What happened

Nothing at all (no recordings, no empty files, no errors)

What did I do?

enabled call recording
selected output directory
disabled buttery optimization
call on 123456 number to get input

Other

Tested with both enabled and disabled VOC_REC_* mixers in /vendor/etc
Axet's call recorder works weirdly, maybe because it's 2 mixers in /vendor/etc/mixer_paths_tasha.xml. If to play with switches, it may start working but not for long. Also it seems that skip silence somehow affects recording too
Mixer info is at the end of the issue

Add support for additional (low-bitrate, lossy) codecs
I know I said in the README that this would not be implemented, but it seems like a useful enough feature to implement. I'll consider adding lossy compression formats if Android's MediaCodec's encoders for them aren't buggy.

Tentative plan:

Add OGG/Opus (Android 10+ only) and ~OGG/Vorbis~ (EDIT: M4A/AAC, see below) codecs

FLAC will remain the default

Both OGG/Opus and OGG/Vorbis will detail to a high bitrate for better quality, but the user will be able to change it

What will not be implemented:

Changing the sample rate. I don't want to deal with broken downsampling on some devices so recording always happens at the native sample rate, regardless of which codec is used to encode the output file. (Eg. Pixel 6 Pro's native sample rate for VOICE_LINE is 48kHz)

mp3, ~m4a/aac~ (EDIT: see below), or any other codec that might be patent encumbered in some countries

AMR-NB, AMR-WB, or any other extremely low bitrate codecs

wav because the audio is exactly the same as flac, but the file size is larger

Failed to record call

I think it only occurs when answering calls received when screen is off. Using the latest version of the app. This is a new phone I've recently started using. Stock ROM with root. I've uploaded the failed oga file as a zip because Github only allows certain formats (like BCR ;-) ) _in_REDACTED.log.txt _in_REDACTED.zip
bug/limitation elsewhere

Add `Android.mk` for building the app together with the rest of the system

If it's maintained in the repo, it won't have to be kept up to date manually (obviously) or - what's worse - the app wouldn't have to be compiled separately.

Changelog

Add a new option for starting the recording in the paused state (Issue: #198, PR: #211, @chenxiaolong)

v1.24(Nov 24, 2022)
Changelog

Notification improvements (PR: #169, @chenxiaolong)

A notification is now shown when a recording completes, with options for opening or sharing the recording in a 3rd party app.

NOTE: Manual action required. For opening/sharing recordings to work, reset the output directory to the default and then select the output directory again. This is required because BCR previously only requested write access to the output directory, but not read access.

These new notifications can be disabled in Android's settings by turning off the Success alerts notification channel.

The file path in error notifications is now human readable instead of a URL-encoded content://....

BCR will explicitly vibrate if vibration is enabled for its notification channels (PR: #167, #171, @quyenvsp, @chenxiaolong)

This is needed because Android will not respect the notification vibration option during a phone call.
