I use Mali Texture Compression to convert a JPG image to a PKM file, no mipmaps.And then I put the PKM file into the raw folder of my Android Project, and load it in my android java code via ETC1Utils, running on Samsung Note2, but it reports "Not A PKM File" exception.Again, I load it via libGDX, it still reports "Not A PKM File" exception.Is there something I missed in converting?
