Q:

Why do some of my Textures cause this error?

I've been making a game using the rokonandroid game engine, but I randomly get an error that causes the layout to just stay as it is, and never update.
The following error occurs:

What causes this error?  Anybody know of how to fix this error?  And is it possible that my textures are causing this problem?

A:

Do your textures need to have the size with the power of 2, like 64px x 64px, 128x128, 256... etc?
