Well, on my tablet I just installed Gimp Inkscape Android. I am in shock........it works, slowly but it works. If you have great patients, it works. It opened with both Gimp and Inkscape on the desktop. A side bar with tabs for each program because they are separate. Then I made two squares, blured one into a shadow, oooh! I shut down Inkscape, then Gimp, what!!!, it's XFCE desktop! They put two powerful programs and Linux XFCE on Android!?!
Slow but it works. Patience Luke, use the open source.
I had to run, fight Vader, so now I'm back.
Now when you are using Inkscape you can't use Gimp. You can close one and full screen the other. I have used other vector apps but what's sweet about Inkscape is the alpha channels. You can blur things nicely, man I love shadows. Slow but it works. My Galaxy Note 10.1 came with 16 gig of RAM memory, I wonder if the 32 gig model runs this better and if a larger RAM model is in the works. Graphics apps use lots of RAM. AAH! they do exist on Android.
