Took from source above... too good not to repost here..

constructor(public navCtrl: NavController, private transfer: FileTransfer, private file: File, private webIntent: WebIntent) {
    const fileTransfer: FileTransferObject = this.transfer.create();
    const url = 'urlApkFile';//Modified this
    fileTransfer.download(url, this.file.externalDataDirectory + 'file.apk').then((entry) => 
    {
        webIntent.startActivity({
            action: (window).plugins.intentShim.ACTION_INSTALL_PACKAGE,
            url: entry.toURL(),
            type: 'application/vnd.android.package-archive'
        }).then(function () {
            //OK
        }, function (e) {
            alert('Error launching app update' + JSON.stringify(e));
        });
    }, (error) => {
        alert("downdload finish" + JSON.stringify(error));
    });
}
