VuDroid in choice list when open an image file about vudroid HOT 9 OPEN

VuDroid v1.2 OS v2.1

What image type you try to open? Djvu? Or something else?

bmp, gif, jpg, png -  the same result for all variants

Of course I can easily select the second item, tick and do not see this list 
anymore (this is what I did) but I think this is still a bug.

Regarding your question. Djvu-files are not associated, when I open them I 
invited to select the type of the file, as well as with any unknown files. Then 
I can choose the type of file - "picture" and then I see this list with vudroid.

//Да! Теперь я могу делать скрины и даже без 
рута :)

pdf vudroid association is OK.

That's not really bug cause image viewer that you are using shows all 
applications that supports image mime type. Cause VuDroid supports image/djvu 
hence it in list. How are you think I should fix it? The problem is there is no 
extension - mime type mapping on system level. Each application tries to define 
their own.

"Cause VuDroid supports image/djvu"

when I open djvu I invited to select the type of the file (text, audio, video, 
picture), as well as with any Unknown files.

Ok, djvu is a picture.
Is that a system bug that djvu-file is not recognized as a picture?

I tried to open through Astro. Astro also said that the "File type djvu not 
found". He did not even offer to assume the type to open.
But when I open 'bmp, gif, jpg, png' through Astro Vudroid does not appear in 
the list.
I don't know how could you fix it - I can not understand how all this works on 
Linux )))

On linux there is some magic module that can recognize file by content. On 
Android this module is absent and hence each application should do it by 
itself. For example Astro have set of predefined extension -> mimeType 
mappings. Also you can add your own (it's our case cause djvu is absent in 
Astro). I think there is no fast fix for this problem.
