"Sticky Notes" sign in App Android client (open source)

[note] Sign-in app, Android client, server use Bmob service, use Office WiFi MAC address sign in, JKXQJ

1, the reason to do this app: the Friday company Administration told me that I did not sign in July, so decided to take the weekend to do a router based on the MAC address of the check-in app.

2, the afternoon I was in the company to draw a sketch, prepare for the weekend to do it.

3, in fact, this app is very simple, backstage with the Bmob service, development efficiency doubled, half a day to make.
As follows:

4, the core code is as follows:

    //Check what network is connected     PublicIntegerCheckwifi(Context context) {Connectivitymanager Connectivitymanager = (connectivitymanager) context.getsystemservice (Context.CONNECTIVITY_        SERVICE); Networkinfo mnetworkinfo = Connectivitymanager.getactivenetworkinfo ();if(mnetworkinfo.getstate () = = NetworkInfo.State.CONNECTED) {if(Mnetworkinfo.gettype () = = Connectivitymanager.type_mobile) {return 1;//return 1, connected to a mobile network}Else if(Mnetworkinfo.gettype () = = Connectivitymanager.type_wifi) {return 2;//Return 2, connected to WiFi}            }Else{return 3;//Return 3, no connection. }return 3; }//Get IP     PublicStringgetlocalipaddress() {Try{ for(Enumeration<networkinterface> en = networkinterface.getnetworkinterfaces (); en.hasmoreelements ();) {NetworkInterface intf = en.nextelement (); for(Enumeration<inetaddress> enumipaddr = intf.getinetaddresses (); enumipaddr.hasmoreelements ();) {InetAddress inetaddress = enumipaddr.nextelement ();if(!inetaddress.isloopbackaddress ()) {returnInetaddress.gethostaddress (). toString (); }                }            }        }Catch(SocketException ex) {LOG.E ("IP address is:", ex.tostring ()); }return NULL; }//Get Mac     PublicStringgetlocalmacaddress() {Wifimanager WiFi = (wifimanager) getsystemservice (Context.wifi_service); Wifiinfo info = Wifi.getconnectioninfo ();returnInfo.getmacaddress (); }
