24-27: Consider using Kotlin string templates for better readabilityThe string concatenation could be more readable using Kotlin string templates.
- return File( - imagesDirectory, (imageGson.id - .toString() + "_r" + imageGson.revisionNumber + "." - + imageGson.imageFormat.toString().lowercase(Locale.getDefault())) - ) + return File( + imagesDirectory, + "${imageGson.id}_r${imageGson.revisionNumber}.${imageGson.imageFormat.toString().lowercase(Locale.getDefault())}" + )
46-60: Inconsistent return pattern in getVideoFileThis method creates a temporary variable
filebefore returning it, while other methods directly return the File object. Consider keeping the pattern consistent with the other methods.- val file = File( - videosDirectory, - videoGson.id.toString() + "_r" + videoGson.revisionNumber + "." + videoGson.videoFormat.toString() - .lowercase( - Locale.getDefault() - ) - ) - return file + return File( + videosDirectory, + videoGson.id.toString() + "_r" + videoGson.revisionNumber + "." + videoGson.videoFormat.toString() + .lowercase(Locale.getDefault()) + )
70-73: Apply string templates here as wellFor consistency with the suggested improvements above, string templates would also improve readability here.
- return File( - videosDirectory, (videoGson.id - .toString() + "_r" + videoGson.revisionNumber + "." - + videoGson.videoFormat.toString().lowercase(Locale.getDefault())) - ) + return File( + videosDirectory, + "${videoGson.id}_r${videoGson.revisionNumber}.${videoGson.videoFormat.toString().lowercase(Locale.getDefault())}" + )

16-28: Well-implemented null safety in the Kotlin conversionGood work on converting the FileHelper to Kotlin with proper null safety handling. The use of the Elvis operator
?:and null checks forimageGson.idandimageGson.revisionNumberensures robust file path generation.app/src/main/java/ai/elimu/content_provider/ui/image/ImagesFragment.kt (2)
126-127: Good improvement in null safety with Elvis operatorThe changes to use the Elvis operator (
?.) for checking if the image file exists is a great improvement. This prevents potentialNullPointerExceptionthat could occur in the previous implementation.
147-147: Consistent null-safe checkingWell done applying the same null-safe approach when logging after the file download attempt. This is consistent with the change above and maintains robust null handling throughout the code.
