Trying to create a starter app with PhoneGap. I’m stuck on this line:

navigator.device.capture.captureAudio(onSuccess, onError, {limits:1, duration:5});

It works fine on iOS but throws this error on Android emulator:

Cannot read property ‘capture’ of undefined

Here’s navigator object, at the time of error (notice there’s no device property which is causing this error)

{
    "language": "en-US",
    "product": "Gecko",
    "mimeTypes": {
        "length": 0
    },
    "appVersion": "5.0 (Linux; U; Android 4.0.3; en-us; sdk Build/MR1) AppleWebKit/534.30 (KHTML, like Gecko) Version/4.0 Mobile Safari/534.30",
    "plugins": {
        "length": 0
    },
    "onLine": true,
    "connection": {
        "type": 0
    },
    "platform": "Linux armv7l",

    "geolocation": {},

    "vendorSub": ""
}

And here’s the PhoneGap object just after Phonegap.js has loaded (notice it says device: true)

{
    "commandQueue": [],
    "commandQueueFlushing": false,
    "_constructors": [
        null,

    ],

        "sms": true,
        "telephony": true,
        "network": true,
        "splashscreen": true
    },
    "available": false,
    "sessionKey": 0,
    "callbackId": 0,
    "callbacks": {},
    "callbackStatus": {
        "NO_RESULT": 0,
        "OK": 1,
        "CLASS_NOT_FOUND_EXCEPTION": 2,
        "ILLEGAL_ACCESS_EXCEPTION": 3,
        "INSTANTIATION_EXCEPTION": 4,

        "IO_EXCEPTION": 6,

        "JSON_EXCEPTION": 8,
        "ERROR": 9
    },
    "mediaObjects": {}
}

Any ideas how to get past this?

    Ok, this is the most douchy solution I ever stumbled upon!

    The JS for Android is different than that for iOS. The files is named the same though – phonegap-x.x.x.js. No points for guessing it’d be different for every other mobile platform.

    I understand that you need to have different JS for different platform, but how about mentioning that somewhere?

    Once I dragged the JS from Android folder, everything fell into place.

    Thanks to this question for the answer: deviceready won't fire in Phonegap 1.0.0 on Android
