I have modified it to have 3D mode and made it a standalone installable APK.
It should work on any android starting from ICS(although on ICS, Photo Editing doesnīt work).
It is based from https://android.googlesource.com/pla.../apps/Gallery/
And it is using HJ200īs 3D Library from here
Full source from here
Download from here - https://github.com/1ackass/Gallery3D...D.apk?raw=true
When rotating, the 3D Button might disappear(Press back button and reselect the image to fix it).
JPS images are showing both images/sides when viewing in 2D
You tell me.
To install it, just open the apk and install it. If it shows some error on installation, put it in System/app(Make sure you replace the original Gallery apk).
