Apps-android-commons: Add Zoom functionality to Explore

[tanvidadu]

Summary:

Add functionality to zoom images displayed after browsing through app ( Just like share Activity) .

Would you like to work on the issue?
If no one takes it up, I will work on it

Thanks!
Just yesterday I was thinking we should add this, because many people want to view the whole picture in full resolution without actually having to press the "Download" button and viewing it with a different app as that is cumbersome and generates a lot of useless files on the SD card.

Yup, I was also thinking of this feature. I also created 1 issue similar to this #1147

The Wikipedia app displays the image in a very clean way. It would be nice if we can have it similar to them.

A next step after this can be adding viewPager support in this feature similar to android gallery.

For adding zoom functionality , should I add a zoom option in menubar or simply add pinch zoom functionality ?
I prefer first option but I am open to second one too! I would love to hear others opinion too :)

For browsing images, I'd vote for pinch zoom, but I'm OK with the menubar if others prefer that. :)

@tanvidadu Are you still working on this?

[tanvidadu]

Nope due to some prior commitments, I am unable to work on it!
@domdomegg feel free to take it up :)

No problem - I'm not planning on taking this up so still unassigned. Thank you for the update and for removing assigned tag :)
