This is used when using Getsystemservice in a class: 1.

 Public classJajamenuextendsActivity { Public StaticJajamenu instance; @Override Public voidonCreate (Bundle savedinstancestate) {Super. OnCreate (savedinstancestate); Super. Init (); Instance= This; }      //Get Instance       Public StaticJajamenu getinstance () {returninstance; }}

2. Call

 Public Static Final int Nettype_wifi = 0x01;  Public Static Final int Nettype_cmwap = 0x02;  Public Static Final int Nettype_cmnet = 0x03;
