I am usually creating simple apps , but after uploading my APK on app store I see it occupying big size .!!!
Also it take a long time to download from app store to my mobile .!!
The question is : Why apk file takes big size , and why it is so slow to down load on mobile ?!!
Mohamed -- if you chose to "optimize with Crosswalk" your app includes additional libraries that are required to support the Crosswalk webview. If that is not the case, then your app likely includes a large number of files that are occupying the APK. Please see these doc pages for more information:
