For heaven's sake. I finally figured out how to add your own icons to Intel XDK Android Crosswalk apps. I'll provide a simple walkthrough since I noticed that this forum and the Intel forum have been lacking proper instructions on how to do things. Instead, people just pop in and give a smart-*** oneliners. Okay, that's my rant. Here's how you do it.
1. Open Intel XDK.
2. Log into your account if you haven't already.
3. Look at the TOP LEFT CORNER where it says "Projects". Click on "Projects"
4. You will notice the page is split in half. The left side is grey. The right one is black. On the right tab, scroll all the way down to "LAUNCH ICONS AND SPLASH SCREENS"
5. Click the "+" logo next to it.
6. It will show 4 tabs. Android, Android-Crosswalk, iOS, Windows 8. Click on "Android-Crosswalk"
7. It will show Launch Icons and Splash Screen. Add the 4 launch icons.
Bam! Now go to the build tab and build your app using Crosswalk!
I bet you did the same silly mistake I did and only added icons to the Android tab. Well. You need to add them to Android-Crosswalk. I have no clue why Intel has two separate tabs for that either.
I have absolutely no clue how to put my AdMob in there. If I ever find out. I will post a tutorial with images and everything because I think it's enough for one of us to suffer.
Some info on Intel XDK Crosswalk:
1. In my experience it is just as fast as CocoonJs WITHOUT the sound/audio issues. Your app will still be bloated because Crosswalk comes with its own engine. So whatever the size of your app is right now, add another 16 MB to it. E.g. my 8 MB application grew to 24.55 MB.
One more tip.
2. Under the Projects tab under "Plugins and Permissions" you can turn off all of the Core Cordova and Intel Cordova Plugins. Like I said, Crosswalk seems to be its own engine that already comes with all of that stuff included. It just makes your app look intrusive when Android is asking for 20+ permissions.
3. If you want to update an old app that is already published in Play Store, use the same Project!!! This is so important. I made the fatal mistake to create a new project. Then I went to upload the new app. Google rejects it because the app signing didn't match. I'm sure some people know how to change the app signing. But, who would want to go through that hassle. Just replace your old exported Construct 2 project to the same folder that Intel XDK uses. Intel XDK will refresh all teh files and all you really have to o is press "Build" again.
Hope this helps.
