Why Intel xdk apk such big file, because you need to embed crosswalk browser. If you don't use crosswalk, the file will be very small, but virtually unplayable because of unpredictability. You could use shared crosswalk  to reduce the apk, but, that might put off your players who may not like downloading the Intel crosswalk separately (about 25 MB).
