Suppose I have a full path of file like:(/sdcard/tlogo.png). I want to know its mime type.
I created a function for it
public static String getMimeType(File file, Context context)
{
Uri uri = Uri.fromFile(file);
ContentResolver cR = context.getContentResolver();
MimeTypeMap mime = MimeTypeMap.getSingleton();
String type = mime.getExtensionFromMimeType(cR.getType(uri));
return type;
}
but when i call it, it returns null.
File file = new File(filePath);
String fileType=CommonFunctions.getMimeType(file, context);
First and foremost, you should consider calling MimeTypeMap#getMimeTypeFromExtension()
, like this:
// url = file path or whatever suitable URL you want.
public static String getMimeType(String url) {
String type = null;
String extension = MimeTypeMap.getFileExtensionFromUrl(url);
if (extension != null) {
type = MimeTypeMap.getSingleton().getMimeTypeFromExtension(extension);
}
return type;
}
