Description

Hello,

If Proguard is enabled, I have this error when I generate an APK :

[ERROR] [system.err] Warning: com.theartofdev.edmodo.cropper.CropImageActivity: can't find referenced field 'int cropImageView' in program class com.theartofdev.edmodo.cropper.R$id ... [ERROR] [org.gradle.internal.buildevents.BuildExceptionReporter] Execution failed for task ':app:transformClassesAndResourcesWithProguardForRelease'.

Can you tell me what is the problem?

Thank you

Research direction
Investigate the Proguard configuration file (e.g., proguard rules.pro) to ensure that the necessary keep rules for the Android Image Cropper library are included. The error indicates that a field 'cropImageView' in R.id is not found, likely due to obfuscation. Add a keep rule to preserve the class com.theartofdev.edmodo.cropper.R$id and its fields. Also check if the issue has been addressed in later versions of the library, as this is an old issue from 2017. Consult the library's documentation or existing Proguard rules in the repository.
