Yet another barcode scanner for Android. As if there weren't enough.
This one is free, without any ads and open source.
Works in portrait and landscape orientation, can read inverted codes, comes in Material Design and can also generate barcodes.
Binary Eye uses the ZXing ("Zebra Crossing") barcode scanning library.
ZXing can read the following barcode formats:
- AZTEC
- CODABAR
- CODE 39
- CODE 93
- CODE 128
- DATA MATRIX
- EAN 8
- EAN 13
- ITF
- MAXICODE (only when unrotated and unskewed, see 77, because of which Binary Eye cannot read this barcode)
- PDF417
- QR CODE
- RSS 14
- RSS EXPANDED
- UPC A
- UPC E
- UPC EAN EXTENSION
ZXing can generate the following barcode formats:
This app uses RenderScript to resize and rotate the camera image. Unfortunately, RenderScript has some nasty gotchas.
It's necessary to call RenderScript.forceCompat() on some devices/roms.
RenderScript.forceCompat() needs to be run before any other RenderScript
function and unfortunately there is no way to know if invoking forceCompat()
is necessary or not.
If RenderScript.forceCompat() is necessary, a RSRuntimeException will
be thrown and the only option is to restart the app, this time with calling
forceCompat() first.
Calling RenderScript.forceCompat() means the processing is done in
software so you probably don't want to enable it by default.
At the time of writing, calling RenderScript.forceCompat() in a build made
on macOS Catalina with build tools 29.0.3 will crash the app. This is a bug
in the build tools for Catalina.
So do not build release builts on macOS Catalina with build tools 29.0.3.
Building on Linux with 29.0.3 works fine.
At the time of writing, it's important to not have the NDK available when compiling the custom rotation kernel. This will produce a broken build for some ARMv7 devices running Android 6 (e.g. One Plus X, Yotaphone 2, Moto E) while it works for newer Android versions.
At the time of writing, ./gradlew bundleRelease will produce a broken
App Bundle without the necessary RenderScript libraries. This is another
bug in the build tools.
If you want to fork this and are only interested in reading 2D barcodes (like QR or Aztec), you may want to remove the custom rotation kernel altogether as ZXing can read 2D barcodes in any orientation.
This will make your app a bit simpler and saves you from compiling a custom RenderScript kernel for each architecture you want to support.
