I have a freshly created Cordova project with the following config.xml setup (used the instructions from http://docs.phonegap.com/en/edge/config_ref_images.md.html). I also added 2 platforms (iOS and Android).
When I run either cordova run ios or cordova run android, the project still has the default Cordova icons. My understanding from the documentation is that Corodva is supposed to create the icons automatically based in the icon.png I supplied in the config.xml.
config.xml:
<?xml version='1.0' encoding='utf-8'?>
<widget id="com.testapp" version="1.1.2" xmlns="http://www.w3.org/ns/widgets" xmlns:cdv="http://cordova.apache.org/ns/1.0">
<name>SingleApp</name>
<preference name="DisallowOverscroll" value="true" />
<preference name="AutoHideSplashScreen" value="false" />
<preference name="Orientation" value="portrait" />
<preference name="Fullscreen" value="false" />
<preference name="target-device" value="handset" />

I wrote a script that auto generates icons for cordova using ImageMagick:
https://github.com/AlexDisler/cordova-icon
To use it, create an "icon.png" file and place it in the root folder of your project, then run:
cordova-icon
and it will generate all the required icons for the platforms your project has.
You can also configure it as a hook in your cordova project so the icons will be generated every time you build the project based on the icon.png you've added. (instructions in the readme).
If you are using cordova 3.5.0 they have updated the docs. In older versions i've always had to replace the icons manually in the project but the latest version of cordova is working fine.
http://cordova.apache.org/docs/en/3.5.0/config_ref_images.md.html#Icons%20and%20Splash%20Screens
As you can see here https://github.com/phonegap/phonegap-cli/issues/58 it's been a common problem. So if you are using an older version of cordova i recommend to update it with the command npm update -g cordova
And after that you should update your config.xml to something like this:
<icon src="www/res/drawable-xxxhdpi/icon.png" />
<platform name="android">
<icon src="www/res/drawable-ldpi/icon.png" density="ldpi" />
<icon src="www/res/drawable-mdpi/icon.png" density="mdpi" />
<icon src="www/res/drawable-hdpi/icon.png" density="hdpi" />
<icon src="www/res/drawable-xhdpi/icon.png" density="xhdpi" />
</platform>
<platform name="ios">
<!-- iOS 7.0+ -->
<!-- iPhone / iPod Touch -->
<icon src="www/res/ios/icon-60.png" width="60" height="60" />
<icon src="www/res/ios/icon-60@2x.png" width="120" height="120" />
<!-- iPad -->
<icon src="www/res/ios/icon-76.png" width="76" height="76" />
<icon src="www/res/ios/icon-76@2x.png" width="152" height="152" />
<!-- iOS 6.1 -->
<!-- Spotlight Icon -->
<icon src="www/res/ios/icon-40.png" width="40" height="40" />
<icon src="www/res/ios/icon-40@2x.png" width="80" height="80" />
<!-- iPhone / iPod Touch -->
<icon src="www/res/ios/icon.png" width="57" height="57" />
<icon src="www/res/ios/icon@2x.png" width="114" height="114" />
<!-- iPad -->
<icon src="www/res/ios/icon-72.png" width="72" height="72" />
<icon src="www/res/ios/icon-72@2x.png" width="144" height="144" />
<!-- iPhone Spotlight and Settings Icon -->
<icon src="www/res/ios/icon-small.png" width="29" height="29" />
<icon src="www/res/ios/icon-small@2x.png" width="58" height="58" />
<!-- iPad Spotlight and Settings Icon -->
<icon src="www/res/ios/icon-50.png" width="50" height="50" />
<icon src="www/res/ios/icon-50@2x.png" width="100" height="100" />
</platform>
As you can see the URIs are relative to the cordova project's path, not to the www folder.
The config.xml settings for icons only works with the PhoneGap Build service. After adding both of your platforms you need to manually (or you can create a hook, but I haven't done that myself) place your icons in the correct paths.
For iOS:
PROJECT_PATH/platforms/ios/PROJECT_NAME/Resources/icons
For Android:
PROJECT_PATH/platforms/android/res/drawable
Android has many res/drawable-* folders, use as applies to your app but at minimum add to res/drawable
Then run cordova prepare or build or run
If you are willing to install extra software for icon generation you can use Ionic which has such function.
Do the following:
npm install ionic -g- Put png, psd or .ai files for icons and/or splashscreens to
${project_location}/resources ionic resources
If you want to generate icons only there is a handy key for that:
ionic resources --icon
More details here
Don't you need to specify the folder that has the icon on it? Cordova replaces the icon with the default one when it is not found.
Have you tried to replace with something like:
<icon src="res/icon.png" />
Try following https://www.npmjs.org/package/cordova-gen-icon
Example:
$ cordova create hello com.example.hello
Creating a new cordova project with name "HelloCordova" and id "com.example.hello" at location "hello"
$ cd hello
$ cordova platform add ios
Creating ios project...
Preparing ios project
$ cordova-gen-icon
Generate cordova icons with
project: .
icon : ./www/img/logo.png
target :
generate iOS icons
Success generate icon set
A little explication for people who say <icon src="res/icon.png" /> Not work !
You must put icon.png in both this folders
project_name/res/
and
project_name/platforms/platform_name/res/
Steps:
cordova create hello com.example.hello HelloWorld
cd hello
Copy your icon.png to project_name/res/
Open config.xml and put <icon src="res/icon.png" />
After that run
cordova platform add android
Now copy your icon.png to ... hello/platforms/android/res/
then
cordova build android
and finally
adb install platforms/android/build/outputs/apk/android-debug.apk
After that you can see on device your app with your icon
