i have followed instructions here creating application embedding api , have integrated cross walk library works , displays remote website url successfully. .apk file size jumped 61.8mb 21.8mb . have enable proguard rules crosswalk inside application. there way reduce size of apk?(at least google play 50mb limit)

crosswalk builds 2 types of arch: x86 , armv7. libraries each of them has weight 20m. in sum ~40m.

there 2 options decrease final build size:

1. build 2 separate apk each arch , upload them google play (it's supported)
2. use light version of crosswalk

for 1st option can check example on github. repository contains example of crosswalk embedding , build flavors build x86, armv7 or combined.
