I have the following textures in AndEngine 1.
512 x 4096 (PNG Size - 500 x 2415)
2048 x 2048 (PNG Size - 2048 x 2048)
2048 x 2048 (PNG Size - 2048 x 2048)
However some of the textures from the bitmap texture atlas do not show up during gameplay. One thing that surprises me is, the textures are visible on a 3 year old HTC Wildfire but they don't show up consistently on Galaxy Nexus or Nexus 4.
In Galaxy Nexus the few sprites just display white rectangles. And on the Nexus 4 some textures mysteriously disappear. Any pointers would be helpful. Thanks.
