Do not yet understand but have had issues.
When Compiling an application using a service the service is compiled and then the application is compiled.
If the Service Module is referred to in the application it must be in the Application uses clause.
It seems there may be an issue with using Global Variables as the basis of singleton objects.
Eg
Var
GlobalObject : TSingletomObject = nil ;
Function GetGlobalSingleton : TSingletomObject;
begin
if GlobalObject = nil then
GlobalObject : =TSingletomObject.Create ;
Result:=GlobalObject
end;
Testing a passed pointer as an object type does not work from a service
Eg
procedure TLocationTrackingForm.ServiceConnected(const LocalService
: TAndroidBaseService);
begin
// if not (LocalService is TFBServiceModule) then Exit; Always exits
Service := TFBServiceModule(LocalService);
// if not (AThread is TISTestServiceThread) then
// Exit;
