mysql get X(point) along with join -

-

i trying run select query joining multiple tables. ont of tables has got column coordinate point type. works correctly in joins not allow me select x(coordinate) or x(point(coordinate)).

i can select coordinate in join , can select x(coordinate) directly on table both dont work.

select x(coordinate) location_coordinate

the above 1 works

select ca.campus_id, ca.campus_name, ca.status_code, ca_loc.location_id, ca_loc.address, ca_coo.coordinate, ca_loc.locality_id, ca_loc.area_id, ca_loc.city_id, ca_loc.state_id, loc_locality.name locality_name, loc_area.name area_name, loc_city.name city_name, loc_state.name state_name     campus_account ca       left join location ca_loc          on ca_loc.location_id=ca.location_id      left join location_coordinate ca_coo         on ca_loc.location_id=ca_coo.location_id     left join location_master loc_locality         on(ca_loc.locality_id = loc_locality.location_master_id)     left join location_master loc_area         on(ca_loc.area_id = loc_area.location_master_id)     left join location_master loc_city         on(ca_loc.city_id = loc_city.location_master_id)     left join location_master loc_state         on(ca_loc.state_id = loc_state.location_master_id);

this works. if try 

select ca.campus_id, ca.campus_name, ca.status_code, ca_loc.location_id, ca_loc.address, ca_coo.x(coordinate), ca_loc.locality_id, ca_loc.area_id, ca_loc.city_id, ca_loc.state_id, loc_locality.name locality_name, loc_area.name area_name, loc_city.name city_name, loc_state.name state_name campus_account ca       left join location ca_loc          on ca_loc.location_id=ca.location_id      left join location_coordinate ca_coo         on ca_loc.location_id=ca_coo.location_id     left join location_master loc_locality         on(ca_loc.locality_id = loc_locality.location_master_id)     left join location_master loc_area         on(ca_loc.area_id = loc_area.location_master_id)     left join location_master loc_city         on(ca_loc.city_id = loc_city.location_master_id)     left join location_master loc_state         on(ca_loc.state_id = loc_state.location_master_id);

it not select , gives me error saying x not column.

android - getbluetoothservice() called with no bluetoothmanagercallback -

i getting getbluetoothservice() called no bluetoothmanagercallback error in android application. i have no idea causing or bluetooth manager callbacks. can give me idea of causing problem or start looking. by reading android source code, seems warning cannot about. source code shows if call bluetoothsocket#connect(); then call bluetoothadapter.getdefaultadapter().getbluetoothservice(null); the key here, null parameter passes in above line. due this, there no callback, , bluetoothsocket class throw out warning. since warning, not think need it. https://android.googlesource.com/platform/frameworks/base/+/master/core/java/android/bluetooth/bluetoothsocket.java line 306 https://android.googlesource.com/platform/frameworks/base/+/master/core/java/android/bluetooth/bluetoothadapter.java line 1610
