Try cutting your texture size in half and I'll bet you have a lot less trouble with the lack of memory and zooming. That's a "huge" texture.
As was mentioned before using mipmapping can help in general but I think the problem is that you are using only a single texture thus when you "zoom in" if you want to retain high quality detail (with a single texture image) you are going have problems no matter what approach you take. I'd suggest breaking your texture into pieces so the 3D engine can deal with only a part at a time rather than the entire thing at once.

texture size is 2048x1024 (multiple of 2) jpg file
i forgot yto change back radius to 6371 km when im using 10 times smaller 637 then theres no memory heap error but zooming doesnt work well
Do you know if there is any restriction for sphere radius?? i thought it doesnt metter how big sphere would be
im not 100% sure what spheres 3rd arameter represents sphere(6378f,Primitive.GENERATE_TEXTURE_COORDS, 800, app), is it number of polygons used to rander sphere or is it number vertices`?
