Question

是否可以检测Android设备支持的频率/频段。我只想检测该设备是否支持3G / 4G网络。

我已使用连接管理器和网络信息打印出详细的网络信息。

“mobile_hipri”是否意味着设备支持3G网络？我怎样才能检测到该设备是否支持4G网络。

编辑：我使用以下代码打印出此信息

ConnectivityManager cm = (ConnectivityManager)getSystemService(Context.CONNECTIVITY_SERVICE);
       NetworkInfo[] info = cm.getAllNetworkInfo();
       for(int i=0; i <info.length-1; i++){
           Log.d("3G4G", "Type : " + info[i].getType()+"");
           Log.d("3G4G", "Type Name : " + info[i].getTypeName());
           Log.d("3G4G", "Sub Type :" +info[i].getSubtype()+"");
           Log.d("3G4G", "SubType Name : " + info[i].getSubtypeName());
           Log.d("3G4G", "SubType Name : " + info[i].getSubtypeName());
           Log.d("3G4G", "Extra Info : " + info[i].getExtraInfo());
           Log.d("3G4G","______________________");
       }

我需要知道工作频率（GSM 850/900/1800/1900或任何其他）设备支持。如果有任何其他方式可以找到该设备支持3G / 4G网络，请告知。
