You can use this method to get File extension. Then you can get MimeType from extension
In Java
public static String getExtension(String fileName) { String encoded; try { encoded = URLEncoder.encode(fileName, "UTF-8").replace("+", "%20"); } catch (UnsupportedEncodingException e) { encoded = fileName; } return MimeTypeMap.getFileExtensionFromUrl(encoded).toLowerCase();
}
In Kotlin
fun getExtension(fileName: String): String { val encoded: String = try { URLEncoder.encode(fileName, "UTF-8").replace("+", "%20") } catch (e: Exception) { fileName } return MimeTypeMap.getFileExtensionFromUrl(encoded).toLowerCase()
}
or as Kotlin extension:
fun File.getExtension(): String { val encoded: String = try { URLEncoder.encode(name, "UTF-8").replace("+", "%20") } catch (e: Exception) { name } return MimeTypeMap.getFileExtensionFromUrl(encoded).toLowerCase(Locale.getDefault())
}
