first, determine whether the network connection is available
Public Static Booleanisnetworkavailable (Context context) {Connectivitymanager cm=(Connectivitymanager) context. Getsystemservice (Context.connectivity_service); if(cm = =NULL) { } Else{//if it is only used to determine the network connection//You can use Cm.getactivenetworkinfo (). isavailable (); Networkinfo[] Info =Cm.getallnetworkinfo (); if(Info! =NULL) { for(inti = 0; i < info.length; i++) { if(info[i].getstate () = =NetworkInfo.State.CONNECTED) {return true; } } } } return false; }

second, judge whether the GPS  is open  Public Static Boolean isgpsenabled (Context context) {           = ((locationmanager) context                   . Getsystemservice ( Context.location_service));           List<String> accessibleproviders = lm.getproviders (true);            return null && accessibleproviders.size () > 0;

third, determine if WiFi is turned on Public Static Booleaniswifienabled (Context context) {Connectivitymanager Mgrconn=(Connectivitymanager) context. Getsystemservice (Context.connectivity_service); Telephonymanager Mgrtel=(Telephonymanager) context. Getsystemservice (Context.telephony_service); return(Mgrconn.getactivenetworkinfo ()! =NULL&&mgrconn. Getactivenetworkinfo (). GetState ()= = NetworkInfo.State.CONNECTED) | |Mgrtel. Getnetworktype ()==Telephonymanager.network_type_umts); } 
Iv. Judging whether it is a 3G network Public Static Booleanis3rd (Context context) {Connectivitymanager cm=(Connectivitymanager) context. Getsystemservice (Context.connectivity_service); Networkinfo Networkinfo=Cm.getactivenetworkinfo (); if(Networkinfo! =NULL&& Networkinfo.gettype () = =connectivitymanager.type_mobile) {               return true; }           return false; }  
Five, the judge is WiFi or 3g network, the embodiment of the user here, WiFi can be suggested to download or online playback.  Public Static BooleanIswifi (Context context) {Connectivitymanager cm=(Connectivitymanager) context. Getsystemservice (Context.connectivity_service); Networkinfo Networkinfo=Cm.getactivenetworkinfo (); if(Networkinfo! =NULL&& Networkinfo.gettype () = =Connectivitymanager.type_wifi) {                   return true; }               return false; }
