检查连接类型是wifi or mobile

ConnectivityManager conMan = (ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE); 
 
//mobile 
State mobile = conMan.getNetworkInfo(0).getState(); 
 
//wifi 
State wifi = conMan.getNetworkInfo(1).getState(); 

if (mobile == NetworkInfo.State.CONNECTED || mobile == NetworkInfo.State.CONNECTING) { 
    //mobile 
} else if (wifi == NetworkInfo.State.CONNECTED || wifi == NetworkInfo.State.CONNECTING) { 
    //wifi 
}
