Notes

For Play Store installs, the Play Store will download and install the barcode library if it was not already installed on the device. For non Play Store-installs, the OS will download the library after it is first used (if it is not already installed). Attempting to scan before the library is installed (which could take several minutes depending on how the OS prioritizes it) will result in the ScanFailed event will be called until it completes.

Compatibility

Android projects on all supported operating systems.
