我想在我的项目中在后台发送彩信，我这样编写代码： How to send image via MMS in Android?

但如果 wifi 开启，我无法发送我的彩信。如果wifi关闭，我可以发送我的彩信成功。

当wifi打开时，我收到如下错误：

我认为它使用 wifi 发送我的彩信。我试过这样

 ConnectivityManager connMgr = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);
connMgr.startUsingNetworkFeature(ConnectivityManager.TYPE_MOBILE,
                "enableMMS");

MMS sending connectivity issues when wifi is active (Android)

但问题依旧，请帮帮我...

【解决方案1】：

我已经解决了这个问题。在打开wifi发送彩信之前，首先你应该调用这个方法：

ConnectivityManager.startUsingNetworkFeature(ConnectivityManager.TYPE_MOBILE,"enableMMS");

当连接处于活动状态时，需要调用该方法：

ConnectivityManager.requestRouteToHost(ConnectivityManager.TYPE_MOBILE_MMS,PROXY);

如果返回true，则可以发送彩信成功。

【解决方案2】：

我也遇到过类似的问题，看来可能与AndroidHttpClient（在HttpUtils中）的使用有关。用 DefaultHttpClient 替换它对我有用。
