android:打开wifi时无法发送彩信

Question

我想在后台发送彩信到我的项目中，我这样写我的代码: How to send image via MMS in Android?

但是如果 wifi 打开，我无法发送彩信。如果 wifi 关闭，我可以发送我的彩信成功。

当wifi打开时，我得到这样的错误:

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)

但是问题依旧，请帮帮我...

我已经解决了这个问题。在打开 wifi 时发送彩信之前，首先你应该调用这个方法:

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

当连接处于 Activity 状态时，您需要调用此方法:

ConnectivityManager.requestRouteToHost(ConnectivityManager.TYPE_MOBILE_MMS,PROXY);

如果返回true，说明发送彩信成功。
