可能重复：
Error opening mobile network settings menu

您好我开发了一个用户需要启用3G Wi-Fi网络的应用程序。

我成功提示用户启用wi-fi并让我进入wi-fi设置位置但是当我为ACTION_DATA_ROAMING_SETTINGS做同样的事情时，结果显示

08-19 13:17:06.291: ERROR/AndroidRuntime(10981): android.content.ActivityNotFoundException: No Activity found to handle Intent { act=android.settings.DATA_ROAMING_SETTINGS

我使用的代码是

Intent gOptionsIntent = new Intent(  
      android.provider.Settings.ACTION_DATA_ROAMING_SETTINGS);  
startActivity(gOptionsIntent);  
alert.dismiss();

任何想法......？
