jandroid uses different implementation for low level graphic routines. Mixing Qt and Android won't work unless none of those low level wd commands have been called.
viewmat itself can work without jandroid and Qt, eg it works for both jconsole and jhs. previous jconsole can call Qt for some graphic functions such as reading and writing graphic files, but this doesn't work for linux server if X11 is not run. Since applicability of this function is limited , it will be decommited. The pplatimg addon will be updated to provide functions of reading and writing of graphic files on Windows, linux and MacOS.
