{ [CordovaError: Platform android already added]

[Ziv-Barber]

I used these settings in my Gruntfile.js:

    phonegap: {
        config: {
            root: 'www',
            config: 'www/config.xml',
            cordova: '.cordova',
            html : 'index.html', // (Optional) You may change this to any other.html
            path: '_build',

            // plugins: [
            // ],

            // platforms: ['android'],

            maxBuffer: 200, // You may need to raise this for iOS.
            verbose: false,
            releases: 'releases',
            releaseName: function () {
                var pkg = grunt.file.readJSON('package.json');
                return ( pkg.name + '-' + pkg.version );
            },
            debuggable: false,

            // Must be set for ios to work:
            name: function () {
                var pkg = grunt.file.readJSON ( 'package.json' );
                return pkg.name;
            },

            // Add a key if you plan to use the `release:android` task:

            key: {
                store: 'release.keystore',
                alias: 'release',
                aliasPassword: function () {

More info:

"grunt": "^0.4.5",
"grunt-phonegap": "^0.15.2",

Phonegap 3.4

Command: grunt phonegap:build:android

BTW:

I'll be nice to have documentation what all these config settings are doing...

I have the same error with phonegap 3.5. Have downgraded to phonegap 3.3 and it works.

+1 I have the same problem

The cordova CLI is creating the platforms directories relative to process.cwd.

workaround: create a symlink at root directory pointing to phonegap.config.path
