I have a hard time understanding what you've built (and don't have an Android device handy to test). The GIFs are jerky, and it's always hard to tell what is going on with touch interactions on screen recordings alone.

From what I can tell, this shows a few interactions for a multitouch file manager, where there is an explicit "selection mode" to reorder/move files; selection is preserved when navigating away from the current view. Additionally, interstitial affordances are revealed to facilitate rearrangement.

My main point of feedback would be to focus on the presentation - it is very hard to tell what is going on, and all I wrote I feel like I had to speculate to interpret. Explain clearly what problem you are solving, and why the current approaches haven't worked for you.

Btw I'm not sure what the claim of newness is; I have seen these interactions in other software in the past (but perhaps I am missing something).
