If you want to test crosswalk, but are blocked by the 25M limit for upload while trying to build:
Start up XDK then click on the 'Debug' tab at the top. Connect your android device to your computer via usb. There is some help information on the screen--you may need to install a driver. Then click the 'rocket' icon and it will launch your app on the device using crosswalk.
The first launch will be slow. After the first time, a project with 51M of assets took 20 seconds to launch on my Nexus 4. Building an APK takes 5+ minutes when you include upload/download time so this is a much faster and easier way to test with crosswalk.
Debug tab also lets you debug your app in Chrome dev tools, profile tab lets you profile the javascript.@IntelRobert, using XDK NEW for iOS I'm getting a black screen testing a project with 7mb of assets. And a white screen on the emulator. Any ideas?
