2.76 - 03.02.2026

• New feature: upload by SFTP (as part of the upload by FTP feature - select the proper protocol).
• The SSH-fingerprints of SFTP servers are checked and added to known hosts.
• The uploading to SD cards and any external folders (user-selected) is debugged and now allows persistent folder connections.
• The «Use Common Storage» mode works again, it saves files to Android/data/ru.ag38.backgroundsoundrecorder/*, this path is accessible by USB.
• The Google Drive uploading is fixed and works again. You have to select a Google Account and give your permission to access files.

2.75 - 30.01.2026

• The Dropbox SSL error is fixed (new libraries applied)
• You can now set the record duration to 2, 5, 10, 20 minutes.
• The entire app is recompiled on a new Android Studio with all new libraries, the APK file is now significantly bigger.
• Unfortunately, the Dropbox fix meant we have to ditch the support of Android 4.4 KitKat. BSR now only supports Android 5 and higher.

2.74 - 10.08.2022

• The new server address is now bsr.ag38.xyz.
• Had to remove an old function for finding neighboring phone network cells. If cell-finding stops working on your phone, try the older version 2.73. 2.73 (download)

2.72 - 29.01.2022

• Updated Dropbox API SDK, hopefully this will solve the expiring Dropbox tokens problem.

2.71 - 24.11.2021

• Fixed a bug with contact name detection, which led to a major dysfunction of BSR. Added more log messages on exceptions thrown by the media recorder (to improve diagnostics).

2.70 - profound changes - 04.11.2021

Upgraded obsolete component libraries, upgraded the interface to AndroidX (looks the same). Target platform - 26 (Android 8). Minimal platform - 19 (Android 4.4).

In case you don't like the new changes, you can get the previous version 2.65 here (download).

• Replaced dependencies with newer versions (e.g. Google Drive, Dropbox).
• Built with the latest Android Studio / Gradle: compileSdkVersion - 28, buildToolsVersion - 30.0.2, minSdkVersion - 19, targetSdkVersion - 26
• Added many new try {} catch {} blocks in critical places to boost the stability of the app (reduce unhandled exception crashes).

Implemented the following suggestions by users:

• New feature: Event Log. Once per several minutes (configurable) it records the current GPS coordinates, WiFi networks, battery charge level, etc. Then once per a different number of minutes the log file is saved as a JSON and sent using the regular uploading methods.
• In order to be able to use the Event Log and related functions you need to purchase the event_log feature for your BSR ticket. (Buy at the Activate page).
• Add a suffix containg the contact name to the recording file name. Also, you can add GPS coordinates, WiFi networks.

New functions for all:

• It's now possible to configure recording pauses for unlocked screens, not only turned-off screens. There's now a special check-box for that which lets you specify that you want to treat a locked screen as a turned-off screen for recording pause purposes.
• It's now possible to delete the current BSR ticket to enter a different one.
• The schedule selector resolution is now 5 minutes (down from 30 minutes).
• Remote command to clear the uploading queues.
