機器人：不能發出彩信，當無線網絡是

Question

我想在我的背景項目發送彩信，我寫我的代碼是這樣的： How to send image via MMS in Android?

但是，如果WiFi是，我不能送出去我的彩信。 如果wifi關閉，我可以發出我的成功。

當WiFi上，我得到了這樣的錯誤：

我認爲它的WIFI發送出去我mms.i試圖這樣

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

MMS sending connectivity issues when wifi is active (Android)

但問題仍然存在，請給我一些幫助...

Answer 1

我有固定的t他問。 之前發送彩信時，無線網絡連接上，首先應該調用這個方法：

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

當連接處於活動狀態，你需要調用這個方法：

ConnectivityManager.requestRouteToHost(ConnectivityManager.TYPE_MOBILE_MMS,PROXY); 

如果返回true，你可以發出彩信成功。

Answer 2

我有一個類似的問題，它似乎可能與使用AndroidHttpClient（在HttpUtils中）有關。用DefaultHttpClient替換它對我來說是個訣竅。
