I had solved the problem with the texture, I reduced the size of all and now the biggest is 871x320, but after adding more items to the project he returned to hang on the loading screen. Many objects in a layout can cause the same error?
— which calculation to find out how much ram each object will use on the loading?
Texture size power of 2 * 4 channels (RGB + Alpha).
Example, an empty sprite that's a size of 1100 pixel wide and 10 pixel high.. is probably just 1 Kb in size. In memory as a texture, it's actually 2048 x 2048 pixels, since it could not fit in a texture size of 1024 x 1024 (its too wide!) so it goes into the next one up ^2.
2048 x 2048 x 4 = ~16MB
If it doesn't fit that, it goes into 4096 x 4096 texture (which a lot of devices won't support, crashing or black box), or ~32MB.
