use your camera to transfer data – even in airplane mode
About this app
Using animated bar codes, it's possible to send data over the air using only the camera. This app is the barcode decoder (receiver). An encoder (sender) can be seen at cimbar.org.
With CameraFileCopy it is possible to receive data over the camera as a one-way data channel. It does not use any antennas (wifi, bluetooth, nfc, ...) or other tricks. Notably, this means it works just as well in airplane mode.
The app reads animated cimbar codes. Nearly all the interesting logic is from libcimbar – included via a git subtree. The sender component of cfc is a cimbar encoder -- such as cimbar.org. Navigate to that website (or use libcimbar's cimbar_send to generate barcodes natively), open a file to initialize the cimbar stream, and point the app+camera at the animated barcode.

How to install this safely
How to verify the file you downloaded
Before you install anything, confirm the file is the one described here. On a computer, run shasum -a 256 your-download.apk (macOS or Linux) or certutil -hashfile your-download.apk SHA256 (Windows), then compare the output character-for-character with the SHA-256 on this page. If a single character differs, the file is not the build we recorded — delete it.
What the signing certificate proves
Every Android app is signed with a private key that only its developer holds. The fingerprint on this page is a hash of the matching public certificate, and it proves continuity rather than identity: it tells you a build came from whoever signed the earlier ones. Android enforces this at install time — if a package claiming to be org.cimbar.camerafilecopy is signed with a different key, the system will refuse to install it over your existing copy. A fingerprint that changes between releases is worth pausing on, because a repackaged app that has been modified by someone else cannot keep the original signature.
How to roll back to an earlier version
If the current release misbehaves, 0.6.4 is the last build before it. Android will not install an older version code over a newer one, so you must uninstall CameraFileCopy first — which clears its local data unless you have a backup. Reinstall the older APK only if its signing fingerprint matches the build you already trust, and check the API range: an older release may target an Android version your device has moved past.
Why we list sources instead of hosting everything
The official store channel is almost always the right choice: it updates automatically and carries the publisher's own distribution guarantees. A direct APK is useful when a device has no store access, when a rollout has not reached your region, or when you need a specific version — and only when the publisher has authorized that copy. APKBrowse does not list pirated, cracked, or unauthorized rebuilds of CameraFileCopy, and a listing is removed when the evidence for it stops holding up.
