Android判断是否是CMWAP联网

Android判断是否是CMWAP联网，如果是CMWAP联网需要设置代理，其他的使用直联网。这个是今天版本最后修改，也是我为Livingphone项目组写的最后的代码。

 public boolean isCMWAP()    {        String currentAPN = "";        ConnectivityManager conManager = (ConnectivityManager) LivingPhoneApplication            .getInstance().getSystemService(Context.CONNECTIVITY_SERVICE);        NetworkInfo info = conManager            .getNetworkInfo(ConnectivityManager.TYPE_MOBILE);        currentAPN = info.getExtraInfo();        if (currentAPN == null || currentAPN == "")        {            return false;        }        else        {            if (currentAPN.equals("cmwap"))            {                return true;            }            else            {                return false;            }        }

 /**     * 获取网络连接对象     */    private HttpURLConnection getConnection(String url) throws IOException    {        HttpURLConnection httpUrlConnection = null;        if (UIHelper.getInstance().isCMWAP())        {            Log.e("ray", "isCMWAP");            int contentBeginIdx = task.url.indexOf('/', 7);            StringBuffer urlStringBuffer = new StringBuffer(                "http://10.0.0.172:80");            urlStringBuffer.append(task.url.substring(contentBeginIdx));            URL urltemp = new URL(urlStringBuffer.toString());            httpUrlConnection = (HttpURLConnection) urltemp.openConnection();            httpUrlConnection.setRequestProperty("X-Online-Host",                task.url.substring(7, contentBeginIdx));        }        else        {            URL connUrl = new URL(url);            Log.e(TAG, "getConnection() url=" + url);            httpUrlConnection = (HttpURLConnection) connUrl.openConnection();        }        httpUrlConnection.setRequestProperty("Accept", "*/*");        httpUrlConnection.setRequestProperty("Pragma", "No-cache");        httpUrlConnection.setRequestProperty("Cache-Control", "no-cache");        httpUrlConnection.setRequestProperty("connection", "keep-alive");        httpUrlConnection.setRequestProperty("accept-charset", "utf-8");        //根据网络类型设置超时时间        int net_type = UIHelper.getInstance().getNetworkType(            LivingPhoneApplication.getInstance());        if (net_type == ConnectivityManager.TYPE_MOBILE)        {            httpUrlConnection.setConnectTimeout(TIMEOUT / 2);        }        else if (net_type == ConnectivityManager.TYPE_WIFI)        {            httpUrlConnection.setConnectTimeout(TIMEOUT);        }        return httpUrlConnection;    }
