71mb added to app size for crosswalk

Solution 1:

I'm also running into that issue. Unfortunately using crosswalk will definitely increase your apk size. However, I found some way to at least reduce the apk size. For instance you could make use of the crosswalk lite. It may reduce your apk size for about 15 MB (see crosswalk lite). You can also specify that you don't want to build the projects for two architectures (explained here).

Solution 2:

Same problem here. I think promissed size of 20Mb is for the apk file which is compressed, you are looking at installed size on device.

You can check generated APK size on platforms/android/build/outputs/apk/ or platforms/android/ant-build/
