嗨,我想用以下代码打开移动网络设置:

Intent intentSettings = new Intent();

intentSettings.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
intentSettings.setAction(Settings.ACTION_DATA_ROAMING_SETTINGS);
             cont.startActivity(intentSettings);

但它给了我这个错误.任何人的想法？

12-10 11:17:34.902: ERROR/AndroidRuntime(623): android.content.ActivityNotFoundException: No Activity found to handle Intent { action=android.settings.DATA_ROAMING_SETTINGS flags=0x4000000 }

谢谢
