推荐答案

要得到这个工作，改变你的意图创建以下code：

To get this working, change your intent creation to the following code:

Intent intent=new Intent(Settings.ACTION_DATA_ROAMING_SETTINGS);
ComponentName cName = new ComponentName("com.android.phone","com.android.phone.Settings");
intent.setComponent(cName); 

基本上Android清单需要一个组成部分过滤器。

Basically the android manifest requires a component filter.
