I am using libusb in my android application. When I am trying to build libusb
native library then I get below error message, *.so files generated.
Error:Execution failed for task ':app:transformNativeLibsWithMergeJniLibsForDebug'. More than one file was found with OS independent path 'lib/x86/libusb.so'

I am on windows machine. Does anyone know what could be the issue ?
I was having this issue in my React-Native Bridge project after I added AAR files of 3rd party SDK. And I was linking the Bridge into my Main React-native application.
Solution (May differ for you):
Add this in app/build.gradle
the Main React-Native application:
packagingOptions {
pickFirst '**/*.so'
}
I faced another issue related to this (If you include AAR into library project that's not being linked to main application)
