ProGuard | .NET MAUI Document Scanner

If you have ProGuard/R8 enabled for the release/production build, please add the following rules:

For the Scanbot SDK for MAUI

}

For the native Scanbot SDK

v1.94.0+

ProGuard rules are integrated into the library and automatically applied to customer's modules.

But, customers who are using DexGuard tool for the obfuscation of the release application, have to add the following rules to the DexGuard configuration to keep the names of .so files unchanged for the Scanbot SDK:

-keepresourcefiles /lib/*/libscanbotsdk.so
-keepresourcefiles /lib/*/libtflite.so

-keepresourcefiles /lib/*/libscanbotsdkdata_gdr.so
-keepresourcefiles /lib/*/libscanbotsdkdata_docdetector.so
-keepresourcefiles /lib/*/libscanbotsdkdata_mcform.so
-keepresourcefiles /lib/*/libscanbotsdkdata_blurdetector.so
-keepresourcefiles /lib/*/libscanbotsdkdata_lcd.so
-keepresourcefiles /lib/*/libscanbotsdkdata_commonocr.so
-keepresourcefiles /lib/*/libscanbotsdkdata_ehic.so
-keepresourcefiles /lib/*/libscanbotsdkdata_ocrb.so
-keepresourcefiles /lib/*/libscanbotsdkdata_barcodev2.so
-keepresourcefiles /lib/*/libscanbotsdkdata_barcodev3.so
-keepresourcefiles /lib/*/libscanbotsdkdata_licenseplate.so

v1.74.0+

info

Since Scanbot SDK version 1.74.0 consumer ProGuard rules are integrated into the library and automatically applied to customers' modules.**

If you are using an older Scanbot SDK version you have to add these ProGuard rules for all Scanbot SDK Packages:

v1.73.x (or older)
