Unable to resolve dependency for ':app@debug/compileClasspath': Failed to transform file 'all-fmmr.aar' to match attributes {artifactType=jar}

[rehab101]

I'm trying to compile this app on my own and learning how it works from the inside. I'm unable to do so because of the error mentioned in the title while Gradle synchronizing the project. It seems this is because the library "all-fmmr.aar" which contains the code needed for the class "wseemann.media.FFmpegMediaMetadataRetriever" used in "VideoDetailsFetcher.java". How should I resolve this?

try this: // implementation files('libs/all-fmmr.aar') commented implementation 'com.github.wseemann:FFmpegMediaMetadataRetriever-core:1.0.15' implementation 'com.github.wseemann:FFmpegMediaMetadataRetriever-native:1.0.15'
