Note that my current workaround to get it built with the icons is to simply move them into the correct position. I do that like so:

mv platforms/android/res/{values,xml} res
rm -rf platforms/android/res
cp -r res platforms/android
ionic build android

However I suspect if I generate a new set of icons or prepare the Android platform again, these steps would be reversed.

I'm also having this exact problem, seems the res map isn't created in the correct location

Yes, having the same issue just after updating Ionic and Cordova NPM libraries.

Using Ionic 1.3.2 app

Cordova CLI: 6.4.0
Ionic Framework Version: 1.3.2
Ionic CLI Version: 2.1.4
Ionic App Lib Version: 2.1.2

Update:

Hmm, mine appears to be a bigger issue than that, none of my Plugins (using the Ionic Native library) are no longer loading/found (all is fine for iOS), installed/reinstalled all plugins/platforms etc, strange because I have managed to upgrade fine in the past..

Also to note:
Upgraded all Android SDK tools..
Uninstalled and Reinstalled Cordova/Ionic

will investigate further...

** Lastest Update **

So after the various CLI updates. It appears if I use an explicit older android cli platform:
cordova platform add android@5.2.2
Fixed the issues with plugins, icons ect, and runs fine.

I have noticed the 'res' folder was appearing (cordova 6) (with the correct iocns) in the root folder of my inital app files, NOT the platform generated folder

So, this should be considered a Cordova issue?

Hi folks,
I have this pb also. I think I know the reason (don't worry it has nothing to do with Illuminatis ;-).
The command "ionic resources" updates config.xml. The code written is partly bad code.
Instead of "density" inside:
It should be "qualifier" as here:
Then magically the build process creates the right folders and copy the right files for every screens.
So basically the CLI has to be patched (PLZ supa Ionic Team).
But for know let's house party: https://www.youtube.com/watch?v=tGJEe-yGLos

this issue started as soon i upgraded cordova to latest (6.4.0).

The same problem here with ionic 2 RC2.

@workfluo thanks man, you solution solved this issue for me. was having this issue as well, my ionic info:

Cordova CLI: 6.3.1
Ionic Framework Version: 2.0.0-rc.1
Ionic CLI Version: 2.1.4
Ionic App Lib Version: 2.1.2
Ionic App Scripts Version: 0.0.39
OS:
Node Version: v6.9.1

I had the same issue with the following system information:

Cordova CLI: 6.4.0
Gulp version: CLI version 3.9.1
Gulp local: Local version 3.9.1
Ionic Framework Version: 1.3.2
Ionic CLI Version: 2.0.0
Ionic App Lib Version: 2.0.0
ios-deploy version: 1.9.0
ios-sim version: 5.0.8
OS: Mac OS X El Capitan
Node Version: v4.4.4
Xcode version: Xcode 8.1 Build version 8B62

and my cordova-android version is 6.0.0

I tried the solutions above but none of them worked for me.

Finally I managed to make it work by downgrading Cordova CLI from 6.4.0 to 6.3.1 by running the following command:

npm install -g cordova@6.3.1

and removing & adding android platform then re-building for android:

ionic platform remove android
ionic platform add android
ionic run android

Note: In this solution, instead of qualifier I keep using density attribute in config.xml. For example, <icon src="resources/android/icon/drawable-ldpi-icon.png" density="ldpi"/> or <splash src="resources/android/splash/drawable-port-xxxhdpi-screen.png" density="port-xxxhdpi"/>

If i try: ionic build android i get this:
Note: /Users/Workfluo/ionic-server/wad/platforms/android/src/org/apache/cordova/splashscreen/SplashScreen.java uses or overrides a deprecated API.
Note: Recompile with -Xlint:deprecation for details.
What does it means?
I've got this , the latest version.

I will try this from ghenry22 in ionic-team/ionic-framework#9060:
"Upgrade to android platform 6.1.0 and this should be fixed, just updated my project, reran ionic resources and then build and all good."

I have this:
Cordova CLI: 6.4.0
Gulp version: CLI version 3.9.1
Gulp local:
Ionic Framework Version: 2.0.0-rc.2
Ionic CLI Version: 2.1.4
Ionic App Lib Version: 2.1.2
Ionic App Scripts Version: 0.0.39
And i use this for config settings:
+
BUT in APK the splash screens are named splash.
It depends probably on cordova or ionic cli version.
Whatever it's unstabil! A MESS!

I would highly recommend to open the .pkg file with an unzip tool in order to check IF in "res" folder you have any image for splash screens AND their name.

GET IT. GOTTCHA YOU BUGGY BUG!
My solution with a config like:
Cordova CLI: 6.4.0 + Ionic Framework Version: 2.0.0-rc.2 + Ionic CLI Version: 2.1.4;
is basically:
after the Command $ionic resource,
in config.xml for all the

REPLACE "density" by "qualifier"
AND
in
REPLACE value="screen" by value="splash"

@camexapps , your solution to do cordova platform add android@5.2.2 worked. NOTE: This is for a cordova backbone app - thought i'd post here since this seems to be more a cordova issue than an ionic issue.

@florentsuc What Node Version you have and SO?

@herkulano Sorry, i have a problem with tha Node 6.9.X, say sys is deprecated. Use util instead. I wanna to know this hide using Node 7.0 or above.

Your system information:

 ordova CLI: 6.3.1
Ionic CLI Version: 2.2.1
Ionic App Lib Version: 2.2.0
ios-deploy version: Not installed
ios-sim version: Not installed
OS: Windows 10
Node Version: v5.12.0
Xcode version: Not installed

I too have the issue.
I just did

cordova platform update android@6.1.0

because I was on android@6.0.0 and it seems it is the cause of the problem.

But then I go through a lot of errors on compilation, plugins errors like:

AdMobPlugin.java:37: error: package com.rjfun.cordova.ad does not exist

import com.rjfun.cordova.ad.GenericAdPlugin;

I tried ionic plugin rm and ionic plugin addall the plugins, but I still see these errors.

Can you help ?

@EmreErdogan solution doesn't seem to work.

Any support for cordova 6.4 is coming ?

Or should I use @workfluo strategy ?

for cordova 6.4 this is working one
apache/cordova-android@854946e

If you're splashscreens and icons are not getting used/copied, run

ionic platform rm android
ionic platform add android@latest --save

Android 6.0 (which cordova currently has pinned as the default version) had a bug with resources not being used.

@mhartington who's better than you?

@mhartington Upgrading to latest android worked for me.

I got Error: cordovaProject.projectConfig.getFileResources after running

ionic platform rm android
ionic platform add android@latest --save

Thanks a lot @florentsuc. I updated android platform to 6.1.3 but seems like only 6.1.0 works well.
