i want add geofence on current location of user when user clicks on ad geofence button.however,after using fused api client states not connected yet.here code-

in oncreate method, correctly configure google api client , call onconnect:
if (mgoogleapiclient == null) { mgoogleapiclient = new googleapiclient.builder(this) .addconnectioncallbacks((googleapiclient.connectioncallbacks) this) .addonconnectionfailedlistener((googleapiclient.onconnectionfailedlistener) this) .addapi(locationservices.api) .build(); mgoogleapiclient.connect(); log.i("api is",""+mgoogleapiclient); } however, several lines below (still within oncreate lifecycle method), have following code:
location location = locationservices.fusedlocationapi.getlastlocation( mgoogleapiclient); startlocationupdates(); log.i("location is", location + ""); if (location != null) { onlocationchanged(location); } my guess first line of section causing error - trying retrieve location google api client still not connected @ point. since have analogous code inside onconnected callback, should able remove second block of code quoted above oncreate method fix issue.
