I am using PhoneGap 2.8.0 for android app.

Need to get the full path of sdcard using javascript in phonegap, because in my mobile it shows the location as file

    Finally i found we can't get the external SD Card Path,

    Environment.getExternalStorageState();

    Its returns only Internal SD Card path

    Reference: http://developer.android.com/reference/android/os/Environment.html#getExternalStorageDirectory()

    Please try this code..

    There is window.appRootDir.fullPath through you get full path but before that you must use dirReady();

            window.appRootDirName = "download_test";
            document.addEventListener("deviceready", onDeviceReady, false);

            function onDeviceReady() {
                console.log("device is ready");
                window.requestFileSystem(LocalFileSystem.PERSISTENT, 0, gotFS, fail);
            }

            function fail() {
                console.log("failed to get filesystem");
            }

            function gotFS(fileSystem) {
                console.log("filesystem got");
                window.fileSystem = fileSystem;
                fileSystem.root.getDirectory(window.appRootDirName, {
                    create: true,
                    exclusive: false
                }, dirReady, fail);
            }

            function dirReady(entry) {
                window.appRootDir = entry;
                console.log("application dir is ready");
            }


            downloadFile = function() {
                var fileTransfer = new FileTransfer();

                var url = "http://www.irs.gov/pub/irs-pdf/fw4.pdf";
                var filePath = window.appRootDir.fullPath + "/test.pdf";
                fileTransfer.download(
                url, filePath, function(entry) {
                    alert("download complete: " + entry.fullPath);
                }, function(error) {
                    alert("download error" + error.source);
                });
            }
        </script>
    </head>

    <body>
        <a href="#" onclick="downloadFile()">Download File</a>
    </body>

    you can also get your directory by this code. code reference from phonegap documentation.

        document.addEventListener("deviceready", onDeviceReady, false);

    // device APIs are available
    //
    function onDeviceReady() {
        window.requestFileSystem(LocalFileSystem.PERSISTENT, 0, onFileSystemSuccess, fail);
    }

    function onFileSystemSuccess(fileSystem) {
        fileSystem.root.getDirectory("App_files", {create: false, exclusive: false}, onGetDirectoryWin, onGetDirectoryFail);
    }

    function fail(evt) {
        console.log(evt.target.error.code);
    }

    var onGetDirectoryWin = function(parent) {

    }
    var onGetDirectoryFail = function() {
        console.log("error getting dir")
    }
